[Q] Lock screen issue

The wildest thing happened to me when I flashed the latest nightly. I originally had a pattern set to unlock the screen and that was backed up in titanium backup. When I flashed the nightly I changed it to a PIN. Here's where the issue comes in - I restored my backup (to get apps and settings back) in titanium then rebooted. Now I can't unlock it. I type in the PIN since it shows the PIN ui but it's actually looking for a pattern though the ui for that isn't showing up. Obviously this is my fault, however I'm wondering if anyone else has had this happen before? I don't want to do a data/factory reset but I see that being the only simple fix. Anyone have another idea though?

I think I know what you mean.
Every once in a while when I have to unlock my SIM it doesn't recognize my pin.
I just blackout the screen and go back, usually it gets the pin right.
Sometimes I get scared when it happens lol.

Yeah that's what I thought it was at first, until I saw the message that I entered the pattern wrong 10 times, now I have to wait 30 seconds. I got it fixed now so I'm happy. I just wonder why or how this would occur. It seems to me that 'if X is true>then Y is true, Z is false' doesn't exist for the lock screen, it's more like 'if X is true>then Y and Z are true'. I guess it's just a quirky argument bug in the system, oh well. It can always be fixed

Fingerprint sensor not working occasionally

I've been recently getting some instances where I would lock the phone and the fingerprint sensor won't respond to my finger.
This really started when I changed my lock to pattern swiping. Anyone have the same issue? I rebooted and changed it back to pin lock and it seems to be working all the time again, but I don't know what caused it in the first place.
Thoughts?

How many fingerprints do you have saved? I have 3. 2 of my left index finger and one of my right. 95% of the time I use my left. Set up several and see if that helps. Move your finger all over the sensor when setting it up so it gets a broad picture of your fingerprint

It's not that it doesn't recognize my fingerprints, but it doesn't recognize fingerprints in general. So when I put my finger on it, it doesn't do the double buzz, it's just non responsive.

this happened to me yesterday several times. And i received phone yesterday... . I have two prints. Left and right index fingers. It didnt fail, just was as my finger wasnt in the reader
MDB08L

experienced the same thing this morning. phone was plugged charging and finger print would not detect, had to manually hit the power button then it worked. i find there are a lot of issues when the phone is charging though, screen sometimes becomes very unresponsive while charging. i think there was a similar thread about that as well.

Just started having this today as well. Sometimes doesn't acknowledge fingertip at all; works if i press lock button to wake the screen. Kind of a bummer, otherwise very satisfied overall. Hope it's just something that can be ironed out with a software update.

Nothing out of the ordinary installed. Twitter, Instagram, Dropbox, etc. Nothing to interfere with lock screen. I do use pattern unlock.
EDIT: Will try PIN unlock instead of pattern for a while to see if it acts any differently.

Any luck? I did a system wipe after unlocking, and flashed new factory images but still happening.

No luck. Still happening either way. I'd say maybe 10% of the time, fingerprint unlock works correctly. The other 90% I have to wake the screen with the lock button first. Sometimes after trying fingerprint multiple times, when I press the lock button and the screen wakes there is a little message at the bottom that says "Fingerprint hardware unavailable" in red where the little fingerprint icon usually is. But then it immediately changes to the fingerprint icon and it works fine.

I was able to find a bit more about this issue. When it happened again, I pressed the power button and quickly checked the fingerprint icon at the bottom of the lockscreen and it turned red and said "fingerprint hardware not available" for a split second before turning white again. I searched that error message and got this thread https://www.reddit.com/r/nexus5x/comments/3pm3lv/fingerprint_hardware_not_available/
I'll try wiping the cache and see if that helps at all. If not, I'm going to RMA.

I'm not much of a tinkerer, but I'll give this a shot. If it clears it up then okay, but if it happens again I'll probably RMA too. Not willing to put up with such inconsistencies on a brand new phone with such a highly touted feature.
Unrelated, this is actually already my second Nexus 5X. The first one I received would not take a charge, and I didn't have another USB Type-C cable to test, so they sent me an entirely new package. If wiping cache doesn't do it, I'm really not sure if I should bother with a third Nexus 5X. Kind of disheartening. I really enjoy the device otherwise.

So far so good for me, Let me know how it goes for you!

I chatted with a Google support rep today, describing the issue and sending links to other message boards that are discussing this topic. He had me restart the phone in safe mode and sent a follow-up email, asking me to check back in after a few hours or a day or whenever, and let him know if the issue happens again. This was about seven or eight hours ago, and I haven't had the fingerprint sensor fail once when pulling the phone out of my pocket. It seems possible that a third-party app is interfering with the sensor's ability to function when the device is locked and the screen is off. I haven't installed very many apps, and they're all mainstream ones that everybody uses. My next step may be to factory reset the phone and stick to stock install for a day or two, then maybe add apps like Twitter, Instagram, etc., back one at a time per day and see if the issue returns. If it is a software issue, I don't think an RMA is necessary.
EDIT: Well it just did it, never mind all that

I've spent the past week emailing back and forth with Google tech support, sending in bug reports, even sending a video of the problem happening (and showing the fingerprint sensor working immediately after pressing the lock button). They've determined that the fingerprint sensor hardware itself is fine, and the problem is that instead of waking the screen it's telling the phone to go into Doze. I'm still sending them bug reports, and they're trying to replicate the problem on their own Nexus 5X to determine what (possibly an app?) is causing the problem. I'll report back in with any more information, in case anyone else has the problem and ends up here.

It happened to me too, stock phone, no third apps installed. I will keep an eye on this.
off-topic: the discoloration of the back of the phone it's very bad!

I believe it's not the hardware as well. I've noticed that it's mainly when I get notifications from something that the sensor stops working.

Did a factory reset, and the problem came back almost immediately. Google tech support wanted me to reinstall OS entirely, but I don't have the right cable (type C to type A) to hook up to computer, so they just gave RMA. Got the new one on Friday, so far so good. But then, with the last phone, the issue didn't appear until after a week or two. Fingers pressed. Tech support really seemed to take my case as a rarity, and they were unable to recreate it with their own device. Here's hoping it's just limited to a few devices.
P.S. Off topic, but Google support wouldn't give me anything for the Black Friday deal. I asked multiple times in multiple ways. Oh well.

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?

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...

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

Random Apps Opening after 8.0

Has anyone else been experiencing random applications opening on the device after the Oreo Update? I have the VZW Varient so i dont know if that makes a difference but im interested to know others feedback

I'm on T-Mobile variant as well as on oreo and have not had such an issue. Which applications have been doing such things?

i've got the similar issue for my z2f EU (xt1789-06) and i'n with 7.1.1
app: amazon, yahoo auction JP, chrome

Hmm..I did notice a couple apps do that..

I've noticed it a few times. Nothing consistent. Probably just the Chinese government making tiny mistakes

Randon apps
Yes im experiencing the same problem with apps just opening over the top of what ever your doing. Apps that I haven't used in awhile. Would love to find out what is causing it

I don't have that issue. The application manager will opens temporarily when device reboots. The only bug I have found is that if I try to disable the amazon app my phone instantly reboots.

I am on Sprint and have used this phone since Sept and never have experienced this, not even on Oreo since I updated on Tuesday.

just to add my two cents. I was having this problem. Turned off Moto voice security and I haven't seen this happen again.

I've got it too, can't figure it out. I'll have to try your suggestion JAWheat411, thanks!
Warning for those who are experiencing it: this bug has the capability to bypass screen locks. Opened up an app today that completely bypassed it. Interrupted my Spotify while at work and saw that app open instead. And I am sure that I locked my phone since I leave it on my toolbox, and don't want all my co-workers in my business.

I'm also having this very same problem. I will also try disabling Moto voice security and see if that rectifies the issue. I will report back in about 2 days.

This is exactly what is happening to my Galaxy S7 edge since the Oreo update. And it goes right past the lockscreen and my security. My phone is always locked, yet I find I've send a nonsense text, or pocket dialed someone, or that a gibberish email is half-composed, or that my calendar is open and a new nonsense event is half-entered. Somehow Oreo is doing all sorts of screen taps, or allowing my phone to wake up and let the pocket do that. And I have enabled the thing about disable touch when in pocket, and I've shut down smart unlock, but that hasn't made a bit of difference.

This problem is happening with my recently bought Moto Z2 Force. It started out random, but then became pretty consistent. I tried disabling the Moto actions (voice command, voice unlock and one button nav) but the problem kept happening afterwards too and became consistent.
It even opened outlook and managed to delete an important email from my boss that I hadn't read yet! Had I not been looking at my phone while it happened, I would have had one unhappy boss.
Even after unlocking the phone, it would just try random unlock codes for a while and eventually lock out the screen for 30 seconds, and then try again. Wouldn't even let me restart the phone. After struggling for more than 2 hours, I was finally able to restart in safe mode and the problem seemed to stop in safe mode. I disabled Moto actions app, deleted data from that app, and also just to be safe removed the HDR+ cam app that I ported. Planning to monitor for a couple of days and see what happens.
This sh!t is just bonkers!

Question Screen lag on unlock

Hello all,
I have this really stupid issue where the phone gets stuck for like 30 sec after fingerprint unlock then works normally or sometimes forcing system UI to work.
I tried factory reset and still have the same issue.
This only came after may update.
Anything im missing or this weird lag is happening to everyone.

Try samsung member app / diagnostic / test every thing
I don't have or saw any problem with may update

Tried that, everything is fine.. I think its a software bug.

I've always hated how slow the PIN entry screen is. You can't type fast at all because the keypad doesn't register fast presses. Once past that screen everything is normal.

It is Samsung UI. I have that seen in almost every Samy´s device. Even the flagships.
