Application on restarting state

Why is it happening? I have to restart my phone about twice a week to make sure it is useable, else keyboard just won't come out sometimes.
It happened on different 4.2 and 4.3 roms, it seems to be memory related, but I shouldn't be running out of memory right? I even tried fancy kernel to add a bit more, but it still happens

Is there a bettre place where I should post this?

Test: Try keeping your phone to bare minimum apps - just the ones the rom comes with. See if your keyboard becomes unresponsive/slowdown. If no, then the issue is not the rom/kernel but possibly your phone usage and app-install habits.
Sometimes the issue is with excessive apps/and or poor memory management to combat the issue. This can be remedied by kernels or limiting the amount of apps you are using.

T989 running very slow?

From last few months, I've been noticing a major slow down in my device. It lags a lot freezes while opening almost any app making the phone almost unusable for daily basis. I don't know what's causing the slow down.
Here's what I've already tried with no positive results:
- Completely formatting SD card + Internal storage and Flashing stock ROM
- Completely formatting SD card + Internal storage and Flashing CM ROM with all android versions (4.1, 4.2, 4.3, 4.4, 5.0, 6.0)
- Frequently cleaning cache partition and wiping all application's cache.
I also have very few apps installed on my phone and there are no major load on the RAM as well.
I am wondering what can cause such slow down?
As far as I remember, this device wasn't that much slower when I first got it about 2 years back.
Does Google services are causing incompatibility with this device causing freezes or this is a hardware issue? (If it is, then which part of hardware could it be?).
Also do you also experience such slow downs, lags and freezing?

You can try to change your kernel and modify a few things. I really suggest using Wild Kernel and downloading the Trickster MOD app on Playstore and change your settings. I usually set my Governor to "ondemand" and it's worked pretty well. I used to have this problem too back when I had the phone on "batterysaver" and it was a mess.

I agree with the kernel tweaks. I"ve noticed that this device does NOT like to go below about 250mb free ram. I've set my LMK settings very aggressively. Accept for foreground applications, I've set everything to 3x normal.
I too am using On demand, tweaked.
I/O set to BFQ
I also like to run Chainfire's Recently (check the playstore) and I set it to max 6 apps with a limit of 6 hours. I only allow 2 Google search instances, no settings screens and I set it to remove each apps documents as well.
With the above, I experience very few slowdowns any more. I should add, that I am using MM roms.

Note 4 Sprint 6.0.1 Baseband PC1 lags

I bought a used Note 4 Sprint and since I flashed marshmallow using odin on it it gets laggy or reboots from time to time.
Is it something with my Baseband? Like should I install a different Frimware or it's a marshmallow issue?
The battery is okay and the screen is all good as well.
And finally do you recommend me any stable ROM or stock ROM ? Thank you I'm advance

You could likely do better with later Marshmallow releases and possibly custom ROMs if that's your thing. I'm on the PJ1 update running UN7 (Note7) port.
Between, Samsung, Google and Sprint, there's enough bloat on a stock Sprint Note 4 to sink a ship. And Samsung can't optimize the RAM caches well enough to suit individual preferences because it favors its native apps that are baked in as well as other system apps from Google.
This optimization may not favor the apps you prefer to run at will so you need to understand how to deal with it. There's Samsung's version of Doze and there's Android's version of Doze on your Marshmallow Touchwiz firmware. Samsung's version will routinely shut your apps down and doesn't do a good job of real time RAM management while sleeping. It's based on a 3 day run theory but it doesn't my user apps use at all; it shuts apps down that haven't been used in three days. This favors apps that it runs in the backgrounds continually.
So turn that of and focus on Android Doze is my advice. You can find both methods in battery management. Smart Manager may a shortcut to battery management but you can use Settings to find it too. You may see App power monitor on first battery screen; I advise turning that one off. Android doze can be found by tapping Battery usage then tapping 3 dot menu button in top right to goto Optimize battery usage. Once there, the dropdown menu will allow you optimize doze by showing all apps. I disable ones I don't want running continually but enable those that may be impacted by doze with screen off only. If you ever wonder why your music or downloads stop with screen off, here's a place to start. Push notifications should happen anyway with doze active so those may not need enabling to run continually.
You may consider freezing apps that show as running when you don't prefer them to even you're checking running apps. You can use Smart Manager often to optimize RAM or get an app that allows you white list some apps and dump cache for non white listed apps on a scheduled basis.
Personally I find Marshmallow Touchwiz poor for RAM management. The UN5 Lollipop ports managed RAM better without having doze. Somehow I think even the Note 5 may not have good RAM management on Marshmallow. Maybe Nougat is a different story? But I do know that Marshmallow proved to be a bigger challenge than Lollipop did, especially the ports. Why would I run Marshmallow? I guess its inherently faster than Lollipop. But only when optimized, IMO.
I also use Boost+ by HTC found in Google Play Store to free up RAM. Samsung thinks many apps I use regularly aren't being used. HTC Boost+ can discern app use better and logs freed RAM so you know it's working.
As a user, you can discern if these suggestions help or not. Just lag, preferred running apps and battery management advice. They may not be every user and YMMV.
Edit: pay close attention to battery capacity at reboots; bad batteries do have a tendency to shutdown, possibly reboot as well. Last time I had a bad battery, it was on a lollipop ROM; phone shutdown at 30% and plugging in charger showed 0%. Marshmallow may be different; battery is suspect for reboots in Marshmallow. I haven't experienced reboot issues with Marshmallow or have a bad battery to add to this suspicion though.

You couldn't have got a better answer very concise and thought out. I can only add that a bad battery will have the same results as far as shutdowns in marshmallow. Never had a reboot issue. However many have with the earlier builds.

Phone freezing twice or thrice a day ! Tried all reset options !

Hi All,
Anybody here with the same issue ?
Looks like a software issue/touch unresponsive issue because usually I find it coming back to normal once I press power button and unlock it again.
Sounds like RAM allocation issue, isn't ?
Thinking to sell it. Please suggest if you guys know a better way to deal with it !
Even if I go to SC, I cannot reproduce the issue at that particular time. They will just reset it and give me back, and that where I don't want to waste my time.
Does this looks fruitful to flash stock firmware again by the unbrick way ? I feel like that will be me last try.

You seem new here, so welcome on xda
One thing you should keep in mind is to be as precise as possible when presenting an issue, your description right now is not very clear, by the title it sounded like your phone actually froze, which could have been a ram or even a power management issue, but after reading your post it seems more likely that your display was wet, or that you were charging your phone, capacitive touchscreens are sensible to that.
Usually a frozen phone does not respond to the power button like yours did, and a ram issue seems very unlikely tbh

My style of using I believe is the same and I had no such issues in my Cool 1 ever in an year. Was a lot better in every way. Picked it up because I loved the looks, but have lost my trust on Huawei. They really need a lot of improvement.

i am having the same issues as the OP (Although i don't know what he means by "going to the SC")
the phone just goes through moments of extreme lag for about 10-30 seconds, sometimes longer, and it makes the phone COMPLETELY unusable during those times. it happens at least once every other day or so, sometimes several times a day, and sometimes it only lasts about 10 seconds, although on a few occasions, it has lasted several minutes, the phone will "attempt" to respond to inputs, but it gets nowhere quick, opening apps i did not click on, closing apps that weren't open, black-screening, half-screening (app on half the screen), etc.. sometimes i have to just power cycle..
i have the exact same feeling as the OP in that i want to sell the phone. (although i type much better, i'll assume english is a second language for him/her)
i like EMUI a lot.. although i think i want a galaxy s8/s9 now.

Since yours is the us variant, I'm assuming you've got 3 gb of ram instead of 4 gb, in which case a ram issue seems much more likely.
Not much of an issue actually, just that you probably had lots of apps open at the same time, leading to almost full ram (so the system starts closing background and even foreground apps if needed, leading to the strange behaviour you noticed).
Just remember to close apps you don't use and you'll be fine

It's 2018 and I think the OP and I know how smartphones work. I am coming from a phone with 2GB RAM and it has no such issues, no matter how many apps and/or games are open. Google explicitly states that closing background apps is unnecessary, and I should think EMUI offers an improvement over stock Android, not a detrimental experience. However, if you are correct and it is the RAM, it is not acceptable and needs to be fixed or I'm buying a new phone from a different company. In today's world, phones will open links to Chrome and from Chrome open reddit, xda app, pinterest, link to Facebook, share to Twitter, etc etc.. every time I click on a button I should not be having to back track to make sure I only have a certain amount of apps open. Nougat limits max open apps to 20 BTW, marshmallow it was 30.. But RAM management CPU management should be better. If it's of any interest, my reported "free" ram always stays at or above 1-1.5GB so I don't think its ram.. CPU or software problem, possibly.. But my Temps are good as well. Yes it's the 3GB version

Just a quick thought of something you could check (I also have the US 3GB version and was experiencing the same issue). Open up Settings > Battery, and other the "Other" section click "Consumption". See if there's any apps there that are keeping the phone awake and preventing it from sleeping. I would get constant lag after only a few hours of use, and it was intermittent just like you're experiencing. I was about to send the phone back, but checked this setting first. Turns out, the CNN app was running the CPU at nearly 100% for hours on end and preventing the phone from deep sleeping. Once I uninstalled that app, I haven't had issues since then. Could be something similar, just a thought. YMMV.
And by the way, it's NOT the ram. 3GB is plenty. You can see how much is being used on the app select screen, and I've never used more than 1.5 with a ton of apps in the background.

Let me help you there guys....i got the US variant too and has these freezing and lags all over the place, what i discover and did was:
1- Not all the apps works well with the phone hardware(they told me that somewhere) so try to test the apps you put on the phone.
2-Delete all the unnecessary apps from emui, that will give you less lag.
3-Check the battery consuming apps like the guy said and if you want turn on the close apps on screen lock.
Now after all of these my phone have been moving better but the problem isnt the ram, is the software so wait a little more so they can fix this cause is really a good value phone

It has to be the RAM management. Huawei must have optimized the software for 4GB, and then released a US 3GB version without changing anything, so it's screwed up even though phone is showing lots of free RAM.

Wao man thats the best explanation for this problem thanks man

It isn't and never was a RAM thing. Android's memory management essentially force closes apps (but shows them in recents) if it needs more memory. Note there is no work involved in that and you'd never know it until you switch apps and it has to reload, shows logo, etc. Amazing how non-solutions we're brought up multiple times and even thanked. Insert that's-not-how-any-of-this-works meme.

Well, yeah, ram issues nowadays should not be present, but I do speak on a basis, I have experienced bad performance and foreground apps getting killed on a nexus 5, which has 2 gb of ram and stock android. I have no idea what's emui's ram management policy, but on a scale, this would be the least likely cause for sure

CPU frequency sometimes lock on maximum frequency values

Hi guys.
I have global device version, without root, everything is default.
Sometimes (independently how exactly I use the device) it could be locked on maximum CPU frequency. I noticed this issue just, randomly. I've installed CPUZ to see more details about phone and then noticed that all frequencies in maximum (1612 first 4 cores and 1804 all another 4 cores).
Then I've installed AccuBattery to see the energy consumption and noticed that when this bug occurs, the device consumes about 210-240 mAh (with disabled all wireless interfaces surely), but after restart, when everything OK with frequencies stepping, it consumes about 110-140 mAh.
I've been facing this issue on 9.5.19.0 and the same on 8.8.16.
Have someone similar issues? Could you please install CPU-Z (or any anorher similar application) and say if everyone has locked frequencies?
Yes, I know, I've checked all background processes, I've enabled debug mode, connected via cable to laptop and.. adb shell -> top, I was seeing on real CPU activity. It could occurs randomly and then only reboot device could fix it until it happen again.
The same bug I found on the same phone in my friend. Strange, actually.

I knew this problem about 2-3 weeks ago. When you charging, it go up top freqs too
That's why I want to use custom kernel. But sometimes ( much less than stock ) locked at top freqs so I think it is Miui system policy also.
You should try some kernel manager to solve temporary.

Aha, yes, you're right. Now I sorted our everything in my mind and seems it occurs after charging.
Do you think the same issue has all people with this smartphone? But just a lot of them doesn't look on that?
But I'd say it's critical bug to have locked frequencies. Why do you think it's like "miui system policy"?
I had many xiaomi devices, only here I faced with this issue. I thought may be my phone has manufacturing defects.. but seems the bug is general on our device.
What the miui version you have?
Ah, I didn't want to root my device.. I wanted to leave it as is, as stock and don't think about all this headache, but seems the time to unlock bootloader.. Because I haven't root, so, I'm not able to use any kernel managers to reset the frequencies/governors

- I'm on Masik 2.5 with BlackBox kernel. If Kirks solve Dual app problem I will switch
- Miui system policy: I can not freeze/delete many system apps/modules after rooted. I also can not disable many Miui services/procsess ( by MyAndroidTools ). Miui also has performance mode for some purposes, can be auto activate in some cases

Does it drain battery faster? It can be caused by one of your user app. Try to remember when this started to happen, and traceback to the time you install/update apps during that period. Use MiXplorer and check the last installed app. There are apps that can triggered to mine cryptocurrency during charging, making your phone super hot and charge very slow. I am not saying it must be a malware, but it can be some apps that act similarly.
Try to boot to safe mode for several hours to check if it really caused by user app. Turn off your phone > Hold power to turn on > As soon as mi logo appear, quickly hold volume down until the phone finish booting (can be up to 30 seconds). You should see "safe mode" watermark at the bottom left corner, indicating all user app has been temporary disabled. Leave it for several hours to see if the battery still drain or the phone stay awake all the time (high cpu usage). To exit from safe mode, simply reboot.
I always found it is kind of a habit to blame MIUI for everything. I am not defending MIUI here, they bloat a lot. I also hate it and I am using RR now. But on several occassions when we troubleshoot, we found out it is one of the user app that cause the trouble, ads, or slow charging; not anything related to MIUI. Blaming MIUI won't solve the problem, only troubleshooting will lead us to the real culprit. In your case, it still can be caused by the MIUI itself. But until you troubleshoot it out, you won't know who is the real culprit.
For comparison, when still using MIUI 9.5.17.0 I can easily achieve 10+ hours SOT within 1,5 days (max is 14 hours). When switched to RR, affected by the wifi deep sleep drain, I rarely get 10 hours SOT anymore. Still in the process of troubleshooting the problem.

I've checked everything. It occurs after charging in most cases. I think that is the bug in governor. Yes, it drain battery a bit faster, but just a bit, I just calculated emergy consumption.
So, when my frequencies was locked, I just connected my phone via ADB to laptop and was looking at the "top" utility to see the load of CPU. And guess what? No load! Idle 796%. (all another 4% for top with refreshing each second and for CPU-Z ran on device).
Weird bug, actually...
I think I have unlock device and re-flash firmware via fastboot to over-write everything.. who knows where bug is hidden.
I've already done full reinstall system. wipe.. but it could occurs even during I read the book. Or just.. enable device, go to CPUZ, and frecuencies locked at max. Absolutely random event

Try not to install anything first after the wipe. Or just try the safe mode. As I said before, it might be caused by the same user app you installed after you wipe.

That's could be.
I've unlocked bootloader and just flashed the last 8.8.16 with fastboot (just had thought about it could fix something, may be some thin deep bug).
But no, after I've installed the firmware with fastboot, I've started to install all my software from Google play. And guess what? I just see in cpuz and see the same - frequencies are locked on maximum values.
Strange .. I don't use something custom, or from unverified sources, just everything from google play.
Even without games (just PUBG). All another software just social. FB, messenger, Instagram, telegram, WhatsApp, Viber, and so on. And I even cannot to see what application could cause that. Don't want to root the device. After I've installed everything and rebooted device (to reset that bug with frequencies), now everything normal. Continue observation...
Just wanted to find someone who has the same issue and at least compare revisions, installed apps and so on...to try to find the trigger which causes this issue.

That's why I prefer the troubleshooting starting from small first, before going thru the whole ROM flashing. 80% of the time, it is caused by user app. A simple safe mode or factory reset will pointed out a very obvious clue immediately.
Not all playstore app are bug-free, we just don't know what happened in the next update of the app.
While you don't state it before, it can be mediaserver bug. It is caused by the mediascan which stucked at certain file/folder during the scan and keep eating CPU cycle forever. But I've never seen it goes thru almost full CPU load. The solution is to rearrange the files/folder in your internal storage or microsd (if you have it), clean up as needed. Sometimes, a simple restart resolve the issue, but not always.
I have Whatsapp. Some users in the kaskus has FB, IG, Telegram installed; I don't see much complaint from them regarding the CPU usage, except that the IG story are cropped/zoomed (16:9 to 18:9 ratio problem). You can only troubleshoot it step by step, by installing one app at a time. It is very lengthy process and tedious. But usually you can spot which app can be the potential culprit by looking at the battery usage of them. Example, you don't use viber at all, by it appears as one of the highest battery usage.

Yes, I understand that and understand why it would occurs and tried to investigate in this way, but...
I have equals application list which I had on previous device except...CPU-Z and AccuBattery (the AccuBattery for now is removed) because of I faced with this frequencies issues.
This morning it happened again. But I just.. woke up, saw on frequencies - everything OK. Then I just.. Instagram, Telegram, Facebook Messenger and Google Chrome and no more. Then I realized that the phone became a bit warm.. I saw on frequencies - it was locked again
As it happened, I've came to office, connected via ADB to laptop and made several screenshots from `top` utility and looked a bit into `adb logcat`. But nothing... IDLE ~798%. And then I've tried to go to all apps and do force stop for ALL apps. But nothing.
I just rebooted device again...

Just concerning about.. there are a lot errors in logcat. But I understand that.. that's ok.
But 90% of logs flowing from system processes, not from apps. But there is nothing critical.. Nothing something what could flow unstoppable text and caused over-loading CPU.
I'm afraid that it could be manufacturing defects
I event tried to re-flash firmware with fastboot (I thought that byte-by-byte flasing into ROM memory could fix some random small issues). But after flashing with fastboot this CPU locking happening again.
Actually.. dunno what to do with that. The last thought to try any custom ROM (may be Lineage OS) with custom kernel and make sure that it is just bug in Xiaomi's ROM..

And I've posted about this bug on official MIUI forum and seems this bug happening with some people.

Talking about me. I've flashed Pixel Experience and for now everything good. Seems that's the bug in xiaomi firmware.

Maybe that's the random issue with certain apps configuration with some users. Not all reporting the same. Seems to be related to thermal engine or CPU governor configuration. But I don't know where it goes wrong. At least you solved it now by flashing custom ROM.

I just used custom firmware just for check is that factory defect. But seems that's issue only with xiaomi's firmware.
Yes, I thought that could be governor likewise. But.. Don't think so, because this low-level things, I think, debugged and enhanced successfully by default. Seems some conflicts between system applications.
On custom ROM I haven't faced with this issue, so...
But this morning I've flashed again the global stable firmware (9.6.3.0), will see how it will going..

Yes, I've got first lock on maximum frequencies.
So, after researches.. I could say that it's a bug in xiaomi firmware. Definitely.

I also have this problem on every MIUI rom, with stock or custom kernel. It happens randomly. I have tested in 9.6.19, 9.6.4.0, and betas 8.8.23 and 8.8.30.
If I flash any custom rom the problem desapears so it must be a problem of miui rom itself.

I have no problem with Miui based custom Rom + custom kernel

Could you specify the rom and kernel, please?
