[Q] HTC Desire Z Freeze During Standby Mode

Hi,
I just got a new HTC Desire Z Bell Branded (A7275) for my AT&T service. I "debrand" it using the debrand guide. I just noticed twice yesterday that when I put it in standby mode, I try to press the power button to turn off standby mode so I can get the screen to slide down to unlock the screen for usage. Well, it did not....no matter what I do...I cannot get the screen to get unlock. The screen is black as if it isn't on. I hold the power button, still nothing. Only way is for me to pull the battery out, put it back in and power it up. Is this common? What is the problem that causes this? Any help would be nice. Thank you in advance.

have you oc your phone at all? have you flashed a kernel? custom rom? and what guide did you use?

I used this guide to debrand my phone.
have you oc your phone at all?
Not a single bit, everything is bone stock regarding CPU.
have you flashed a kernel? custom rom?
I only flashed the one from the guide.
[ROM] RUU_Vision_HTC_WWE_1.34.405.5_Radio_12.28b.60.140e _26.03.02.26_M
what guide did you use?

Thanks for the fast reply and help, bahmanxda.

Tbh I am not sure what is the problem I got nothing ,the only thing that I can think of is if you are already rooted and s/off do a full wipe and flash the Rom again or try different roms if u like sense try virtuous 9.0 its really good.

There are some others with this issue. Unfortunately, the cause has not been found, or whether it is hardware or software related:
http://forum.xda-developers.com/showthread.php?t=857584&highlight=pulling+battery
I've had this crop up myself a few times. I can say this:
Several times my Desire Z has powered off and could only be powered on after pulling the battery and re-installing. It did this twice within the first few days I owned it. Then it didn't happen anymore.
Maybe a week later I tried the Godspeed kernal (1 GHz) and SetCPU. No issues for about 2 weeks.
Then I tried CPU Tuner based on claims made by some users here that it is easier on battery life. Used a screen-off profile to underclock. The phone had the power off problem, 3 times in 2 days. Every time when the screen was off. But the random poweroffs did not start immediately after installing CPU Tuner, maybe 2 days later.
I uninstalled CPU Tuner to see if it would help (and it didn't seem to be improving battery life). Went back to Set CPU (have messed around with and without screen-off profiles). Its been more than 2 weeks, and no random power-offs.
None of this is conclusive, of course. Maybe the problem in my case was CPU Tuner, or a combination of the kernal and CPU Tuner. Maybe the things I've described are complete coincidence, and its some other factor altogether. But just thought I'd throw my experiences out there. Some claim Google Maps is the problem, but I have not found this to be the case. Or possibly some issue with the battery contacts, or the battery itself. Who knows?

Same thing happens to my Bell Desire Z. Every now and then it just decides to freeze and Only solution seems to be to take out the battery and then put it back.
Very frustrating.

Thanks for the reply, everyone. Strange it has not happen for the past 2 days now. I've read the other thread and still no exact detail on the cause of this. This is not good...especially it is my first Android phone and first HTC (bought it due to their reputation of quality made phones).

It happened twice within the first week of using the phone. Decided NOT to return the phone to observe it for a full month. During that month it happened every 3-4 days, always happens when the phone is not charging, and at the hour mark. Decided enough is enough and returned for a warranty claim 2 days ago.
During the one month, I rooted the phone after 2 weeks and flashed a custom ROM, but the problem did not go away.
There're people who aren't affected by this problem though.

I've the exact same problem here. CM 6.1.1 will just randomly black screen on standby. No response to charge when plugged in. The only way to reset is to pull the battery.
I don't think it happened on stock firmware. I'm now highly debating switching ROMs. It's getting annoying to remove the back cover every time I need to do a hard reset.

I think there is a thread in regards to CM and overclocking causing a screen on issue. But I think in those cases, the phone has power (LED and front buttons light up), just the screen can't power on. But adjusting any overclocking/underclocking profiles is worth a try.
Do you have SetCPU or CPU Tuner setup, and any profiles under those, such as underclock when the screen is off? I tried CPU Tuner for a few days, due to claims by XDA users of better battery life than SetCPU. I got 3 instances in 3 days of the phone not being able to power on (had to pull battery). I un-installed CPU Tuner, switched back to SetCPU, and haven't had the power on issue crop back up for almost a month now.
Given, I had the power on issue 2 times before using CPU Tuner, so it can't be the sole culprit. My only theory is that some combination of switching the kernel and SetCPU has solved the issue. Or it has nothing to do with those at all, just a coincidence, and is something else completely. Who knows.

It happened to me many time already. I still use stock htc desire rom and never rooted..

I've had it happen about 6 times, always requiring a battery pull. Totally stock other than being unlocked, not-rooted. But it hasn't happened for the last 3 weeks or ever since I stopped using juicedefender. Coincidence?

Desire Z freezes
Hi,
I also have some random freezes of my Stock Desire Z, I didn't do a thing on software or hardware side.
I run Android 2.2.1 Build 1.72.405.2 CL296256, provider KPN (Rabo Mobiel)
I got rid of the hangs after the upgrade from 2.2.0 then after several weeks it came back, only solvable by removing the battery.
I tried to figure out what's wrong and I think I have several clues:
- mostly some time after using Google Maps
- mostly when Wifi was on (it might be that the Wifi has limited connection and it screws up the data)
- after the reset I allways have updates from Market available
I can't remeber the Memory widget I ran, which I felt was having a good influence on the hangs.
I'm not happy with this behavioure, but cannot determine if it is hardware or software, it's not helping much that the phone just stalls , a reboot is irritating but less then a complete hangup when you don't know how long it has been in that status.
P.S. I don't run juicedefender
Cheers, Edward

I have STOCK G2 ROM.
S-off, CID, unlock via http://forum.xda-developers.com/showthread.php?t=855764
NO Cputuner or SetCpu (well I uninstalled them before these problems cropped up)
Used G2 for about a month and a bit no problems. Installed launcher pro then started to experience this problem. Coincidence? Not sure. Uninstalled and it did not help. Uninstalled several more apps that I recently loaded (skype, minimalistic text, Gtab Simi clock...) didn't help.
Wiped phone, nandroid backup to original ROM, restored using TB. Worked for a few days then just started happening again.
I also was using 2 chinese batteries I bought from eBay. Not sure if this has anything to do with it either.
// Just reflashed, HTC stock battery. Froze up within an hour. Too bad I bought this off of ebay, no warranty
// Factory Reset, restored apps and data with TB, still freezing

Hi all
I'm new to this forum (sorry, a newbie about to make a whole load of gaffs, no doubt), but I am at least fairly tech-savvy. I've had HTCs for years, right from the days of the 2000 vintage Compaq Ipaq!!
My wife & I bought two Desire Zs at Christmas, and it was therefore 50:50 which box was opened by whom. It appears I picked the dud, as I'm suffering from the issue described by all you guys, and in the other thread:
http://forum.xda-developers.com/showthread.php?t=857584
For the sake of adding more evidence to this otherwise confusing issue, I thought I'd join the forum:
So:
1) The device is not modded in any way. Standard ROM from HTC, being used on the UK T-mobile network. Currently at Android 2.2.1, Kernel 2.6.32.21-g540976a, Build 1.72.405.2 CL296256 "release-keys". This was installed on Christmas day, over the air.
2) There has been no playing with processor speeds or memory management.
3) The first crash of this nature was either on Christmas Day or Boxing day (ie the day-after-christmas-in-England); can't quite remember now, but certainly after the ROM update.
4) I have had this occur irregularly, but in increasing frequency, since that date. I think I'm probably into double figures by now, but I've only started to log them recently.
5) I was starting to think that there was some correllation with GPS applications. The phone would die after using Google Earth, for example, but not immediately. It may be after two or three standby's that it would fail to respond on the fourth, for example.
6) I had a very bad day a few weekends ago where the phone died four times in a single day. I had been using geotagging-photos (in the standard HTC camera app)... plus location-based services such as Yell and Google maps.
7) I tried keeping GPS disabled, and to be fair, there was no evidence of it crashing at that point. But I use GPS too much to make this plausible for a long time.
8) I wondered if it was due to the motion of keeping my phone in my pocket, but it died over night on the bed-side table on Monday-Tuesday, where my last usage had been the Friend-Stream widget/app. GPS was on...
During all of this, my wife's phone has not shown any of these symptoms. Whilst she uses Google Maps, Google Navigator & HTC Navigator a bit, she generally keeps the GPS turned off except for specific odd occasions. Hers has not crashed in this manner...
About to contact HTC to see what their response is...

This has occurred for me regardless of app usage.
It can occur right after a fresh reboot after being fully charged.
// Wow, I was in the middle of sending a txt and it just shut off on me...
I really wish I had a warranty on this

Hey there.
I can clearly pinpoint the problem with my desire z to the GPS. In the first view weeks I used it regularly and my phone froze, but only when the gps sensor was not active anymore (and the phone had gone to standby once or more). It didn't matter which app I used. For a while now I haven't been using GPS and my phone runs smooth as hell.
@lost800: I suppose your problem has a different kind of nature.
I already contacted HTC (very good support) and they told me to send it in to repair. I need my phone for work at the moment and I haven't found time to do this.
Due to the very small amount of ppl having that problem, I suppose it's an hardware error.

Edit: Just out of curiosity, is there any meaning to the kernel version? Or has every mobile phone the same one?

Hello all, here is my input on this problem
My DZ has started freezing while I'm doing stuff:
* playing cards
* writting an email or a text
* using xda app
* ...
I never have GPS on. The frequency has greatly accelerated in the past 2 weeks but the weirder thing is that the last 3 times I remove sdcard and then put it back in to get the phone to boot, but it does not boot... it hangs on HTC logo for a long time (I've left it there for up to 15 minutes to see...) I eventually just remove the battery and from the phone and wait before trying to put it back in and boot...
Wait times required have varried from 5 minutes to several days.
I have observed this behavior on Stock 1.34.405, Virtuous 0.9, Virtuous 1.0.0 and back on stock 1.34.405 Today. I've wiped, flashed stock RUU nothing has helped. This puppy is going back for repair/exchange (it is 3 months old).

I called HTC support to see about getting the phone replaced. After explaining to the guy that it was freezing and then not rebooting when I pulled the battery out, the first thing he said was: "Did you install apps from the market ?"
Given that I replied by the affirmative he wanted me to test rebooting in safe mode and seeing if the freezes still occured before moving on to a replacement. He claimed that some market apps are not "properly coded and can mess up the phone"
I asked for and got the instructions how to reboot into "safe mode" (hit keyboard S key at HTC logo and stay on it while it boots)
In "safe mode" you can still install apps but they won't appear in the app drawer so you won't be able to start them (you can start them if they are on your home pages though ). No backgroud apps will run though (bbc, task killer ...)
Well I ran in safemode for 6 days and used the phone as I always do (work email, leisure email, web, video, camera, games, GPS, bluetooth etc...) and the darned thing ran perfectly. No freeze during those 6 days (the last few times it took less than 2 days to get a freeze).
I therefore decided it was time to test it again in "normal mode". Before rebooting I removed my task killer as for me this was "THE APP" that "safe mode" was really blocking from running on my phone...
Well It has been 2 days now and still no freeze. If it stays that way for another week I think I will have a rather good idea of who was the culprit...
Will keep you all updated and keep my fingers crossed.

Hi guys
An update:
HTC over the web-support were very helpful. Immediately they suggested that the device needed to be taken in for repair. In subsequent stages of the dialogue, they stated that the mainboard would be replaced.
A couple of weeks ago, I cleared down my device, packaged it up and waved goodbye to it (sniff...). HTC took it and...
!!DID NOTHING!!
It came back on Monday with an *old* ROM installed (1.35... If I remember correctly), and a statement saying 'no fault found'.
I've built the phone back up to where it used to be, including installing the over-the-air update to 1.72.405.2 (I need this as there's an activesync exchange bug in the old ROM) and within 24 hours, the device was unresponsive again
I have just written back to HTC to find out what the next steps are. I'd be interested to see if they suggest some debugging actions, like the safe-mode option, for example.
I've also asked them directly if their engineers have any clue what is causing this? Fundamentally, I don't see how any app should have the power to kill the device, however badly written it might be. That suggests insufficient controls/barriers in the OS.
Throughout this period, my wife's phone has continued to operate perfectly, even with some extra GPS playing to try to force a failure. So, we are now looking for any differences that could help to pin this down further. One difference is that she has never enabled the HTCSENSE.COM account on her phone, whereas I had. Perhaps there's some problem with the Phone Location functionality (in addition to the fact that I have to be in a yacht off the West coast of Africa for it to accurately show the phone's location). To test this, I've removed my HTCSENSE.COM account this morning.
Dwardo: I think your issue is slightly different, but the safe-mode info is useful.
Thanks
Andy

[Q]random reboots on my xperia play

Guys I've been having random reboot issues lately and i can't figured out what is actually happening. Sometimes it just reboots itself, randomly every time.
I thought flash another rom or kernel would solve the issue but it doesn't seems to work, any ideas?
I'm currently on DFR3.0.5 rom and DF kernel.

Are you overclocking and/or undervolting?

not really, i only overclock when i play certain games, otherwise i'll set it back to normal.

Is this question sounds stupid? It seems that nobody else would bother to reply it?

i have it some times like every 6weeks believe it or not its currently on stock, but that's made no difference had it happen on custom Rom's also and its allways at about 5 am just sitting there rebooting over and over. not sure if that's what you are getting?

it just sometimes rebooting itself, so i have no idea how and why

Try reflashing back to stock and don't change ANYTHING. Install your programs or whatever, but don't root it or any major system changes.
Use it for a while and see if it reboots. If it doesn't, you did something to it, overclocking/volting, and you need to figure it out.
If it keeps doing it, I hope it's under warrenty. But it also could be the battery.

Hardware isse
I have had 2 XP's and both returned as they randomly rebooted. When I called Dial-a-Phone(UK) to enquire they put me through to their support department. I had to do a factory reset, then install an update from Sony's website and try it out. Still did not work so they said it is a hardware issue. Fortunately I returned mine withing 28 days so got an instant replacement. Pity the second one did the same. I have returned that too and am awaiting my 3rd phone(what can I say, I love the phone). If this one does the same thing I will be moving though cannot be without a reliable phone at the moment(expecting baby) I hope you are covered by the warranty. Good luck.

Annoying as f*** I know mine are fairly rare they were more often when I was all stock two things that reduce it are an apkiller and everyday reboot

Mines been rebooting randomly for the last three days now. In fact it just rebooted while I as reading this.
Sometimes tends to happen when I slide in or out the keyboard. It's breaking my heart as I love this phone :-(

If you have tried to repair the phone software via PC Companion and not installed any third party app's and it still reboots it needs to be checked at a repair center.
Contact your local support team for info about repair centers.

I have had the same problem, but my phone is only rebooting during games(especially HD games). Almost everytime I play Shadow Guardian HD, Backstab HD, or NBA Jam. I never have problems with FPSE and psx games. I am using DOOMkernel v. 11 and I OverClock to 1.14 or 1.21 max and 249 min when I am ready to start up my games. I am also using supercharger V.6 on 512 hp. Should I be overclocking at a higher voltage to stop reboots?

I started getting random reboots under .62. And hooking it up to logcat I was getting ANR errors from a ton of background 3rd party apps.
I think my issue was related to moving from Link2SD to App2SD. I forced all my apps to .android_secure and I think there was one app that didn't play nice. Anyhoo, restored back to .42 and my sd-ext and it works like it did.

3rd one going nuts!!!
An update to my previous posts. Received my third one late last week and have been really using it to make sure it does not randomly reboot. No problem there I am happy to say. The problem I had a day or so ago, is that when I was typing a text message fast, my screen went bonkers and started typing by itself. It then opened my phone app and selected a contact to call, it then opened and closed some apps and closed them. I pressed the home screen but nothing, so powered down and booted it up again. It just carried on going crazy so powered down again and took the battery out, the sim card and also the SD card too. This seems to have "fixed" it for now as I have not been able to replicate the problem. Anyone else had this issue?
FYI - I have been playing Asphalt 6 HD with absolutely no problems at all, as well as a couple of other games.

I think i just had a reboot yesterday night by itself...the reason i know it is the application will kinda er....reset it's position in drawers, some apps shortcuts disappears from my home and so on.....
just when i thought my problem has solved.........

I think it was batter

I also got this problem after changing with china battery. But when using an original battery it was ok. I buy extra for gaming. But now my original battery already missing. Hadoii...

To determine if your phone rebooted overnight, you can install "Android Terminal Emulator" from the Play Store and run the command "uptime", it tells you how much time has passed since the last boot
Or find an app that tells you that...

So is there no fix/ solution for random reboots?

I got my Nexus 7 when it first came out last year, rooted it, installed TWRP, and have been on several different ROMs since. Didn't have any issues with random reboots for several months. Early this year, I started having an issue where the tablet would freeze while I'm using it, then automatically reboot itself. I thought perhaps it was a problem with the ROM I was running, but I had switched ROMs a few times after that, and every single ROM I've been on since then has had the same problem. It usually only happens when I'm browsing the Internet (with Chrome being my browser of choice), but I've had it happen once while using the camera app, as well.
The other day, I upgraded TWRP to the latest version, and I installed the 4.04 bootloader in preparation for Lollipop ROMs. I was hoping on some slim chance that perhaps an upgraded bootloader might fix the problem, but I'm still getting random reboots.
I know I've seen people talk about random reboots as well, but in the past, I never saw anyone find any kind of solution. Is there one, or is it one of those things I just have to live with, at this point? It's odd to me that I didn't start experiencing this issue right away, and that it only started several months after I had had the device. To me, that makes it seem like it's not a hardware issue/ defect, but I guess no one has been able to pinpoint what the problem is, why it occurs, and how to fix it, huh?

I'd tend to agree with you it's a software thing. However, my approach would be a bit more radical than yours: that I would erase everything, including formatting the internal storage twice (after making a backup, of course), then install a completely clean rom, use it for a while to make sure it doesn't act up again before restoring any apps.
On the side, I've seen a Nexus doing random reboots whose owner had opened the back and bent the cover somehow, which slightly depressed the power button. While the button operated normally, this condition forced it to "click" randomly, which caused the reboots. It stopped after the owner replaced the back cover. You might want to check this part. Good luck.

Most of the time, random reboots are kernel related. If you are overclocked try to set max CPU lower and see if the problem fixes itself. If you don't overclock try installing something like Trickster Mod, and lower max CPU to see if that helps. What ROM and kernel are you running?

I always recommend flashing back to stock to rule out software issues. If it continues, you've got a hardware issue.

I haven't really messed around with kernels, I've typically just used whatever was included in a particular ROM, and I never adjust to overclock or anything like that. I don't remember what all the ROMs I've been on are, but I've been on CM before, and I'm currently using CleanROM. I think the only time I ever specifically tried a different kernel was a while back, when I flashed an Elemental kernel, but I've since wiped and been on a different ROM.
For now, I'm trying to hold out wiping anything until a good, rooted build of Lollipop is available, at which point, I'll try wiping out everything, including internal storage, and see if that helps.
I guess I could also try flashing back to stock before I do that, though. I think I've seen one stock ROM for the N7 floating around. The only problem is, it's really hard to "test" this, because the reboots are very inconsistent. The other day, after I had updated the bootloader, I was browsing Chrome for over an hour before I got a random reboot. One time, I was browsing Chrome for an hour and had 4-5 random reboots within that hour. So, that makes it difficult to determine if it's fixed in a timely manner. :/

Alright, so now that there's a proper build of Lollipop out, I did a factory reset and wiped internal storage (twice), and I'm now running stock Lollipop. I spent about an hour or so getting everything set up, and no reboots thus far; but the reboots mainly occur when I'm using Chrome, and I didn't really do any browsing, as I was getting all my accounts and apps and whatnot set up. Hopefully within the next couple of days, I'll have used it enough to get a good idea as to whether or not I'm still experiencing issues.

So far, no reboots, though i don't want to jinx it, heh... I'll be glad if the issue is finally fixed, but I'll also feel kinda dumb that all it took to fix it was something as simple as wiping internal storage and/ or reflashing a stock ROM. Lollipop is pretty nice, as well.

Yeah I'm using a custom version of L myself. You need to flash custom kernel to get working root access with SuperSU BETA 2.19

[Q] Phone problems since day 1.

Hey guys!
Sorry for the long post, I'm going to write down in one post the story of the phone, because I've had so many problems with it (probably because I'm an amateur) since day 1.
1. When I got my phone I had the usual problems, lagging interface, subpar battery life - I installed nova launcher, tried all the best, it was nearly ok.
2. When android 5.0 came out the phone by itself didn't offer it, however when I plugged it in the PC Suite said that there was new software available, so I installed it. This happened again with another update. The weird thing that after every update, when I switched on the phone it said something like 'the current version is not available for user, somethingsomething' as a notification, but I could easily press the side and it disappeared.
3. About a month ago my phone started going crazy. Firstly it overheated really fast. Secondly, which was much more annoying, it rebooted at random times. A week ago it started rebooting so often I could barely use it. I tried monitoring which apps they were, uninstalling but nothing changed.
4. For this reason I rooted, tried memory leak fix, tried greenify and amplify. The problem still persisted. So my thoughts were, that this must be a hardware issue (the reason I thought this, is because sometimes after rebooting it said it had below 20% battery, even if before rebooting it showed 60%).
5. I unrooted (I think I nearly bricked my phone), and put on stock TOT, so I can bring it back to the provider for a fix. Now it has android 4.4.1., the lagging interface is still there, the problems are just like at day 1. However there is no random rebooting, so its not hardware issue, so Im not rushing to my provider (they take a month and dont give substitute phone).
I tried software update again (I'm european d855), but it said there werent any new software available. I would like to have lollipop.
Please can someone explain why it was overheating and how I can have a stable and rock solid android 5.0 on my phone with normal battery life and without lagging interface? I would love to love this phone but it makes my job very difficult
Thank you in advance!

Have you tried any custom ROM?

Xperia Z1C sudden crash and reboot

Hello,
I want to mention that I didnt have any problems with my phone until 1 week ago. I just connected my phone to the charger right before I sleep, as usual, but I didnt notice that it rebooted the whole night. When I woke up I saw my phone with the time crashed and it was really hot. I turned it off for 2 hours but that of course didnt fix anything, so I tried to repair it through Xperia Companion. Then my phone seemed to be fine until a few hours later, it crashed and after a few minutes it rebooted. I didnt give up and I reset it to factory settings, but no difference at all. The phone keeps crashing and rebooting at random times (sometimes with an error message like " {this app} has stopped working", various apps but usually "Xperia Home"). What could cause this issue?

When I woke up I saw my phone with the time crashed and it was really hot. I turned it off for 2 hours but that of course didnt fix anything, so I tried to repair it through Xperia Companion. Then my phone seemed to be fine until a few hours later, it crashed and after a few minutes it rebooted. I didnt give up and I reset it to factory settings, but no difference at all. The phone keeps crashing and rebooting at random times (sometimes with an error message like " {this app} has stopped working", various apps but usually "Xperia Home"). What could cause this issue?

If it's persistent with a phone restore by PCCompanion, I would say some hardware failure. Are you rooted? You could maybe try with a different custom rom or something, and see what happens...

Thanks for replying, I'll try a custom rom. Do you have any good one to suggest?

If you don't care about camera, any of the newer N roms are very nice - https://forum.xda-developers.com/sony-xperia-z1-compact/general/z1c-nougat-roms-t3460868. If camera is an issue, you'll need to stay on LP. Try Jaguar or Cm12.

*UPDATE*
I searched a bit further about my issue and in the depth of my search I found someone that told that some clean type apps can cause this problem. I have Clean Master on my phone so I deleted it. From that time I havent experienced any crash or freeze or reboot. I still dont know the reason I had this app for 8 months without any problems, I dont understand what changed now.

I thought when you said you restored with PCCompanion that meant that it was happening with clean flash and no apps installed. Cleaner apps can often cause those types of problems, and it's questionable if they even help anything. If you must have one, I recommend SDMaid.

It didnt even cross my mind that it would be any difference to mention that I reinstalled all the apps I had because I never thought that such a "usefull" app could do that damage to a phone. Im glad its fixed .

Same problem. Connected my phone to charger, wake up next morning and saw that data disabled that pops up every time phone boots, but i didn't bother and just swiped it. Later that day i kept on seeing those notifications but i didn't bother as always until my phone just froze while i was using it. I could lock it but screen just went black and same image stayed there when i unlocked it. I had to restart it with that force button under sim cover. Problem was still there after reboot so i did factory reset and it was good for few days (more like 1 day) but it happened again. So i did system reinstall with pccompanion and it worked until for a week maybe and i thought i fixed it until few hours ago when it happened again. Phone was hot whenever that happened and crash.monitor keeps crashing ironically (i think that's the cause.) I never had any cleaning apps (i had clean master app lock for locking my apps tho)

oh my god... this is exactly the same Problem and I've been having it also for about the same time. It happened first on the night from Wed, 21st to Thur 22nd. When I woke up I only saw this screen which says, thats its restoring Apps (E.g. "Restoring apps 70 out of 200" and ongoing) Happens sometimes when it crashed - which was rare - so I didn't bother too much with it, but it kept freezing suddenly and randomly at any kind of app and screen went black, only thing I could still do was long press Power button, but sometimes it wouldnt even recognize the touch e.g. to select reboot. After a while in that state it soft rebooted itself. I also force rebooted it a few times with Power + Volume Up Key.
Also tried everything, like factory reset, Software repair through Xperia Companion, then switched SD-Card, an even replaced the battery because I didn't know what else it could be. This got me so far, that I was considering flashing a different Rom and just f*** it. Now I happen to find this thread by looking through the Xperia Forum - I didn't find it through Google... That's kinda sad, I might've not opened my phone if that App is srsly at fault... but oh well. I am just as surprised as you: I thought it could be an app but had everything up to date. And tbh.. I didn't even bother with this Clean Master. I installed it 3 years ago and used it a few times.. and kinda forgot about it, so it didn't come to my mind at all that this could be the problem. I'll uninstall it now and report back if it's solved for me, too.

Can you go to diagnostics and see application incidents. If you see only crash monitor tell me. That's where problem lies most likely

In diagnostics in "start" tab i can see everything. It says 19 systems incidents, 96 application not responding and 75 Application incidents. All of this was from yesterday and earlier. Hadnt had a crash today but I'll see how it goes from now on. What do you mean by "see only crash monitor"? You mean if you didn't accept sony to collect the crash data?
You also wrote, you were using Clean Master, did you uninstall it and did this fix the issue for you, too?

In system accidents there should be only com.sonyericsson.crashmonitor.
I said i was using Clean Master AppLock not antivirus. It's just app that can lock other apps with pin so nobody can acces it without pin.
Also you can check out this where we discuss about same problem

umm in system incidents it only shows a time and date whenever a crash happened. If you mean App incidents instead: I think I understand what you're getting at. As in: If theres another app in the incidents, this is the culprit. Well, as I said it happened very randomly before you can't pin it down on a certain app. Whatever I was using crashed and gave a crash report but most incidents were with "system-ui" Anyways, had no crash since uninstall of Clean Master. So I'm good for now.
When did I mention antivirus? Im referring to this:

So Clean Master, even if you only use it to Pin Lock your apps, might be the problem. Do you still have this problem anyway? Seems like yes, since you're considering to flash a custom Rom.

You don't need phone to be turned on to use xperia companion and flashing new software. Just open it click on repair software and follow instructions. After that just dont install official facebook app since thats most likley cause of crashing. Install some 3rd party client like simple pro. I use that one its awesome
