SM-T815 freezing from time to time - Galaxy Tab S2 Q&A, Help & Troubleshooting

My SM-T815 (Tab S2 9.7 4G) has a habit of becoming completely unresponsive to all touchscreen actions for 20-30 seconds. This can happen in a wide variety of apps. I'm running stock Android 6.0.1. The hard button usually works.
Has anyone else had this problem?

I came here to see if someobody else has this problem. Apparently you do.
The Tablet freezes from time to time, screen turns black, and it becomes unresponsive for a few minutes.
I have many apps on a fast external SD, I figured this might be one of the reasons.
Strangely it has become worse the past few weeks.

My screen doesn't go black - it just stops responding to all touches (the home button usually responds though). I also DON'T have any apps installed on the external SD card. So it sounds like we may not have exactly the same problem????

[Q] Galaxy Note not waking up?

I can't put my finger on this issue I've been having with my Note.
Don't get me wrong, this device is a godsend!
The problem I've been having is that sometimes when I take my Note out of my pocket and try to press the unlock or menu button it doesn't show anything on the screen. I've read about people having issues with delay before it pops up, but it doesn't pop up even after 10 seconds or a minute, it feels like the device 'hangs' or doesn't want to wake up. The only way I can turn the phone on again is by pressing the unlock button for like 10 seconds and the phone reboots.
I thought it was a problem with Green Power, I thought it maybe had issues turning off the wifi or data when the screen was locked and that the service would cause the OS to crash or 'hang'. When I look at my battery history after the reboot it shows that I lost a significant amount of battery (5-15%, depending on how long it took for me to 'discover' the crash) and there's a 'jump' in the graph.
Things I've tried:
Stock rom - problem persists
Different kernels - tried all the kernels available in the market including stock, problem persists
Add a bit of paper between back-cover and battery (to make sure it doesn't lose contact)
Checked if there was dust between battery connections
Tried different sim card
Tried disabling wifi and data all day (mysteriously persists)
DIfferent governors (ondemand and interactive) (the phone reverts to default governor after the forced reboot, normal? i have my phone set to interactive on boot, but somehow it skips that after the forced reboot)
I've attached a picture of the battery graph. According to the stats there's a 25 minute gap where the phone was 'stuck' and you can see that the screen was on and active for that duration.
There are NO funny apps running in the background, this is is a clean install with some standard Samsung apps frozen.
tl;dr version: phone randomly won't wake up; battery loss after forced reboot;
I might have found the issue myself. Now when I come to think of it, I think it always occurs after I've been in my car for like a 30 min drive... Maybe the phone is having trouble switching networks? Anyone know what might be causing this?
Or better yet, how can I research this issue? Can I enable some logging somewhere to track this?
I had the note for about 10 days and today, about 1 hour ago it happened to me for the first time. I tried the home button to wake the screen but nothing, tried the power , nothing and holding the power but nothing happened. I had to pull the battery.
I had this problem in the beginning, but no more.
It's one of two things, in my case. Restoring apps (with data) from Titaium backup, or SetCPU or both. Do a factory reset, reinstall apps without data. If using setCPU, disable it for a while to see if it happens again. It's been over a week and the problem is gone.

I was using System Tuner instead of SetCPU to freeze apps and change governor, maybe I've just been using the wrong app? I deleted it just in case. Will see if the problem persists, thanks!
The nasty thing about it is that it seems to happen randomly (but it most likely doesn't) and is pretty rare (happens once every 3 days).
Still, I don't like the fact of not being available for X amount of time, even if it's 30 minutes.
I'm on stock room and unrooted. Like I said first time it's happened.
i've had the GNote since 4 days now , and yesterday same thing happened as the device was in my pocket and i couldnt wake it up at all , battery pull solved it.
im on stock , non rooted
I can't believe that we are the only ones with this issue. Anyone else? OR better yet, how did you resolve it?
Dont know if this is the same issue as the streak had, but with the streak if you kept it your pocket with the screen facing your body this would sometimes happen. Flipping it so that it that the screen doesnt face your body in your pocket solved this issue.

Thanks for your reply. I did some research, and apparently it had to do with static being built up in the screen from wearing it towards your body in your pocket.
This issue was that you couldn't swipe the lockscreen cause the touch screen wouldn't respond. The problem we are having is that the screen won't even turn on and that the system locks up.
Same issue here with my 2 days old Galaxy Note, that's how I found this forum. In my case it went from not waking up occasionally to every time WIFI was ON (I did some experimenting with settings to see which one could be the one causing the problem). But then...occasionally it would not wake up even with WIFI OFF: very annoying. And this is my first Android, so I didn't have any custom anything, pretty much same as out of the box when I got it The only solution was to reset the handset. And definitely has nothing to do with having it in my pocket as I don't carry it in my pocket. Rang Samsung, they told me it was faulty, I returned it. Now I'm concern the next one is going to have screen issues? As so many people complain in this forum? we'll see.
My issues have been resolved after flashing AbyssNote 1.4 and when I stopped using System Tuner. I've started using Voltage Control instead and now I'm not even having problem @ 100Mhz undervolted 50mV from stock.
Same problem with my wife's Gnote, totally stock, just a small handful of apps installed. Happened twice, about a week apart.
She does a lot of travelling, maybe you're right about that. But it happens after she gets home when it's still OK.
Had the same same issue twice in two days and had to do a battery pull, just did a master reset and re -installed the applications manually, so far so go.
YOu guys think its a hardware or a software issue?
Hmm.. Happened to me too about three times in the last two weeks. I am on stock rom but rooted, and running Green Power. Hopefully samsung will fix it in the next updates. Seems like a software bug to me. Maybe not enough juice when in deep sleep?

Hello
its the problem of your kernel. try Abyys 1.4 and use XDA Superpower to adjust the CPU-Frequency automatically

It's very well possible that the stock kernel has faulty settings for the CPU. Haven't had the problem again with AbyssNote 1.4 and Voltage Control (even with custom cpu frequencies)
I just got my note today.
Battery in, turnt it on a few mins playing around.... the problem started
and hasnt since stopped...
Anyone tried contacting samsung about this?

at this point we're just guessing, there haven't been any official confirmations of the problem as far as i know.
But if it's so accute that it keeps happening all the time you must have a faulty device.. call samsung ?

Touchscreen problems

hey,
since one or two months i have some troubles with my touchscreen. Randomly it starts to press something that i didn't touch and when i stop touching the screen, the system touches from alone. mostly opening google now by swiping up the home button. it also types thigns in whatsapp or so. Sometimes when i turn on the phone the touchscreen doesn't respon. all those problems are solved when i turn off the screen for 5 secs and turn it on again. i am running eXistenZ v3, i also tried some aosp 4.3 roms and had the same problem.
Any idea ?
EDIT: because the problem is solved as soon as i turn of the screen and on again i am not sure if it is really a hardware problem, is it ?

I was just about to post with the same issue!
I replaced the screen and back cover on my Xperia Z back in August and it was running issue free for 2 months but after the update last month to 4.2.2 I started having serious issues with touch screen.
Random inputs, no response to touch, looping homescreens and random apps opening and worse.
I am torn between a hardware issue?
As when the USB cable is connected the problem seems to gone so I think there may be a slight voltage leak screwing with the screen?
What is the best way to ensure that it is not a ground/voltage leak issue?
Or
Or because the issue cropped up almost immediately after the last Sony update, is there a chance it could be a software issue?
I am running on Stock 4.2.2 and any advice will be much appreciated
I have noticed yesterday that my Z's screen keeps pressing a certain spot randomly. Its by the O / P when i use the onscreen keypad. I opened the note app and drew lines, and there is an actual break in the lines when i draw in that area. This happened so sudden. I didnt drop my phone or anything. I just noticed it while typing that the letters started to get jumbled.
I have the same issue but only on certain kernels, I'm using that XZK "Stock kernel" with dual recovery and it's fine now (Note: This kernel only runs on Sony roms) Also, not sure if it's related but if i leave my phone to charge over night, ill turn the screen on and the touchscreen won't respond at ALL unless i hard-reset...

It might have even been a corrupt update, if you run windows go onto the sony application and get it to RE update your phone see if it fixes, it might. And if it does, yay. if not, then atleast you've ruled that out, right?
Well I noticed a small distortion in the screen on a white background in the area that my screen was experiencing random touches, and today I pulled my phone out of my pocket....and 4 cracks spread all over my screen....cant use the touch screen now have to look to order a screen

[Q] Various issues with new Note 4

I tried to search already and didn't find any threads that answered what's wrong with my note.
So I finally updated my note 3 and went and purchased the 4. Got it home, immediately noticed quite a few things.
1. Incredible lag in almost everything. (I turned off all the bloatware, s-voice, flipbook, etc..., also changed animations/new launcher)
- If I try to go to phone, it takes about 5 seconds to pull up and show the dialer.
- going back to homescreen takes about the same, sometime turns the screen off.
- scrolling is almost broken, it stops and stutters a lot. I've gotten some FC's from it.
- apps take awhile to launch, some I can understand, but the calculator shouldn't take that long.
- everything is just really slow. (I'm used to my note 3 and nexus 5 tbh)
2. It takes me almost 3 button presses to get the home screen to come on, when it does come on, takes about 3 seconds to appear.
3. proximity seems to be broken, it goes black while I'm looking at it, if I go to type, turns off and sends me to the lockscreen a lot.
4. Won't mount any of my sd cards ( I have various classes/speeds and sizes, none work, one is brand new out of the package)
5. After a restart, I have to wait at least 20 seconds to have everything load from the lock screen to the launcher.
6. Overheats a lot, while browsing it gets pretty heated up, I don't really play games on mine, it's worse when I run sketchbook on it.
So, a few things, I'm holding off on rooting, just in case I have to return it. I've disabled everything, I don't have many apps installed, I don't over-charge it, it's in a lightweight case, never been dropped, I've barely had it. It's not rooted, flashed anything, it's pure stock with nova launcher and it barely works without something happening.
So what do you suggest? A dud, go and return it? I can't seem to find a source to the issue, resetting to factory didn't fix anything, in fact it mae the lockscreen issue worse.
Mine does none of that. Take it back
Sent from my SM-N910T using XDA Free mobile app
If a factory reset didn't work, return it. No way is any of that normal.
Dosent even take AN SD CARD? Whaaaat yea man I'll take that back. Not normal at all
ROLL THAT SHT, LIGHT THAT SHT. SMOKKKKE THAT SHT
I would have taken the phone back before even making this thread... It's pretty obvious the phones not functioning correctly

[Question] EuphoriaOS 1.1 Freezing/Restarting/UI Unresponsive

Hi. I tried to post in the EuphoriaOS thread, but I don't have enough posts to say something in the development section.
My Nexus 6 is currently using the latest official EuphoriaOS 1.1 and everything has been great up until about a month ago.
This happens sporadically. My phone will start to freeze in the middle of doing anything.
Ex1. I'm listening to Spotify and my music will freeze every 10 seconds or so. Instead of being like a normal skip, it picks up exactly where it left off.
Ex2. I push the power button to wake my phone, but nothing happens for ~3 seconds. Pushing it again will bring up my lockscreen, but my lockscreen is totally unresponsive, so I can't unlock my phone. I can use the power button to turn the screen back off. Then I will wake it again like normal, and It unlocks just fine.
Ex3. My UI in general becomes sluggish and at times completely unresponsive.
Ex4. My phone will just restart randomly. It has done it numerous times each in different applications. I haven't been able to pinpoint a cause.
I enjoy using Euphoria and do not want to update to any Marshmallow ROMs because I have everything the way I like it. My battery is great and Marshmallow currently doesn't have Xposed.
I haven't really installed anything new since before these issues started. They just happened out of the blue.
This stuff happens maybe every couple days at totally random times.
Could anyone help me in trying to fix the issues I'm having?

phone randomly turning off

Hey all just checking to see if anyone has same issue, it is persisting beyond an update. I plug in for night and usually every morning screen is off. Takes me holding down power button for ten seconds for it to come back. Not sure if I'm rebooting phone and it was on or if it was off.
Same here. Got it 2 times. No idea!!!
Exactly same issue, happens every 3-4 days.
I have same problem. After last update, that hapoend 3 times already. I wonder why...
Guys you have to search before posting. Here is the topic i made a while back. Have had this issue since then and i notice it because i have the aod (always on display) and the screen disappears.

Apps i suspect:
Blockada
Owntracks
Health mate
Spotify
Which of these are you guys using? Maybe we can deduce if its an app or some firmware issue.
From your list I'm using only Spotify. However I'm afraid that my phone was turning off even before I got this app. Will check anyway (already uninstalled it), and will let you know.
What I can say for sure is that my phone is switching off completely (not only display) as all my Bluetooth devices are disconnected straight away.
Hope we will find a solution for this issue!
it happened to me twice as well, having the phone for almost 2 months. It is a bit annoying and I dont understand why it happens. Among the list of these apps, I only have Spotify installed as well.
I dont have any apps from Your list. My phone turned off twice since last update, before that, for 1 month everything was ok. Now seems good aswell, we will see.
Seems like its none of the apps. My phone also completely disconnects from my devices and none of the buttons work (like double press volume button for camera). Have to hold the power button for a while and it starts up.
My Always on display is off
Random phone off was happening before the update and it's still happening after!
Also at times phone send to be so sluggish! 7gb+ram still available at that time.
North America 12gb/512gb.
All stock.

Ok, this issue together with the reported complaints of dust in camera lens has made me hold on the purchase of this phone.
Isn't there an official ROG II forum where all of you can complain so Asus can look into this issue maybe request dump files and resolve it once and for all?

Well my doesn't randomly turn off and I'm using blockada if that sheds any light...
Also, I don't use Spotify
I have deleted all the apps. Literally done a reset to the factory settings to see what happen and this morning phone turned off again... That's really annoying.
I have found relevant topic on Asus forum: https://zentalk.asus.com/en/discussion/12715/rog-phone-2-12-512-freezes-and-auto-restart-problem
Looks like they are not fully aware of the problem....
Is there any update for this case?
I'm experiencing random hangs as well after updated the firmware to the latest. It reads my power button and will shows the options to reboot but the UI is totally not responsive, have to hard reset it Everytime.
Since factory reset everything seems to be fine, however it's just few days since I have done it.
09/12/2019 - I can confirm that after factory reset everything works fine. If anything change I will let you guys know straight away.
02/01/2020 - Annnnnd it's back... After few weeks phone started switching off again and tbh the whole thing intensified. Yesterday phone went off 9 times. On top of that when it's off it drains battery like crazy - 5mins and 20% is gone. Bluetooth doesn't work properly as well. I'm aware that others don't have any problems with ROGII, however I'm afraid that due to personal experience I won't buy Asus phone again and won't recommend it to anyone.
Rog phone 2 turns off automatically
Same problem here happened twice in 2 days everytime phone is off i have to hard restart to switch on the phone
Does anybody got any solution for this problem
Yes I have faced a similar issue since I have updated to android 10 beta. This happened once. I left my phone for charging and the screen blacked out. I had to press the vol up+dwn and power to restore the functionality. Strange.

What version of beta you use?
It happened to me twice in three months. The smartphone got stuck/freeze in standby mode: no response from the physical buttons or touch. I use the official android 9 rom.
I managed to restart it with the power button and volume up/down pressed for 15 seconds.

No apps install in the list nd it randomly switch off my phone it's software issue
Mine started turning off after 1 minute of use. Couldn't stop it nor control it.
Managed to barely get the WhatsApp backup and then factory reset the device. So far things are ok. But setting up from scratch is a pain in the ass.
I suspect that I tried to enable twin apps on WeChat while being on Nova Launcher. That may have triggered something, But I'm not sure.
