Ok so I am having a strange touch screen issues with both mine and my wife's tab S 10.1. It started on mine several weeks ago. When using the device, the touch screen will all of a sudden stop responding. If I press the home button, the device goes to the home screen, it just does not respond to any touch. If I press the power button to put the device to sleep and push it again to turn it back on the screen is working again but it will freeze up again, sometimes in less than a minute. When it first happened I tried to do a factory reset to see if that would help and the problem actually occurred during the initial device setup then so I know it's not related to an App that I have installed. I have sent mine to Samsung now three times trying to get them to fix it. They have replaced the screen once and said that there is nothing wrong the second time (still waiting on the determination of the third time). I have tried to research the issue but have not seen anyone experiencing the same thing. I do not have the rebooting issues that others have mentioned and turning the screen off and then back on does make it work, at least temporarily. I only remember noticing it since upgrading to Android 5 so I am going to try getting the device downgraded to Android 4.4.4 to see if that helps. Wanted to see if anyone had any other ideas. Samsung has basically told me if their techs say there isn't a problem they won't do anything for me.
A few people have mentioned touchscreen problems after upgrading to v5.0.2 mostly 8.4" but some 10.5" have you had any horizontal/vertical lines on the screen.

I have never noticed any lines. I have noticed after the first time at the repair center that the touch screen also seemed to be acting erratically, jumping around when trying to scroll or pan instead of having smooth motion. If I am able to get the device downgraded to KitKat and that improves things, I will just stay there until they figure out what is wrong with Lollipop.
I have stayed on kitkat because of the problems with lollipop, it`s just not worth it to me, but the majority of people don't seem to have any problems with it, I cannot see how upgrading to lollipop affects some touchscreens and not them all, but some people have reported the problem after upgrading i just don't know what to say.
It is normal for the touchscreen to behave erratic if you use it while your tablets is being charged, it is mentioned in the user manual.
I would say you have a faulty touchscreen, do you use a screen protector, have you tried the setting that increases the sensitivity of the touchscreen.
John.
I did not know about the charging item so that might explain the erratic behavior. I thought it might explain the screen locking up too but I know that has happened at times when I am not charging the device. I will be interested to see what happens this time when it comes back the third time from Samsung and whether downgrading my wife's device helps the issue on hers or whether we will need to fight with Samsung about hers as well.
For a couple months, I've had exactly the same problem on my Galaxy Tab S 10.5 (SM-T807V). It comes and goes in severity; some days, I lose all touch input every 5 minutes, it seems, while other days, I can go hours without trouble. Using the device without a case seems to help, as does restarting it, at least temporarily.
I have not sent my device to Samsung, nor have I performed a factory reset. But based on your experience, I'm not sure if either option is worth it.
Hi.
I would suggest removing any screen protector and cleaning the screen looking for any damage, download a touchscreen tester app from google play and testing your screen.
After searching around i found an touchscreen recalibration app for android, but i am very wary of it being fake or causing more damage or that it is for a specific brand of phone/tablet.
EDIT: I used an hex editor, and found this text within the apk file, see photo below.
John.
Well Samsung is finally sending the device back to me. This time they said the found the problem and replaced the main board and updated the software. So we will see what happens when it gets back to me tomorrow.
For anyone who is having this problem like I did. My wife has not had problems since she stopped using the device while it was charging. I have not had problems with mine since it got back related to this but whether that was Samsung fixing the issue or the fact that I also am not using it on my charger, I do not know. So if anyone else if having the problem, try the charger thing; otherwise, you may be looking at some kind of hardware issue that Samsung will have to resolve for you.
Most devices behave erratically while being charged. My HTC does it so does my tab.
Samsung even mention it.
Hi, i am having EXACTLY the same issue. The tab toucj freezes and normalizes if i lock it and unlock it with home button. I think its a software issue.

I have two of these from Verizon (T807V) and after updating them to 5.0.2 they both have this same behavior.
Quite annoying.
Any luck finding a cure ? I have noticed that the ram usage gets crazy. Any given time 1.8 gb is utilized out of he 2.77 gb available. I have uninstalled quite a few apps and shut down background processes but still the system is eating too much ram. Can any one help me on how to monitor aap ram usage ?

Hi.
I was reading the HTC forum as i have qone of their phones, and i read that some people were using an Samsung touchscreen app to boost the touchscreen as they were having problems, the app is called "SGS Touchscreen Booster" link below, The Tab S1 has it`s own touch screen booster in the settings, maybe try that first.

That's how android works. Its pointless trying to reduce ram usage if there is still ram to spare.
Android utilises ram not wastes it.

I had multiple problems with 5.0.2, ram hogging, touchscreen problems, my solution was to root and install a custom rom 4.4.4 the tablet is so much more responsive after reverting back to kitkat. I know it's not a solution for everyone but it fixed mine (SM-T800). Just throwing it out as an option.
Used kies today to upgrade to the latest firmware but still the problem continues. I have the Samsung sm t807v Verizon locked. Is there a way I can downgrade it to kit kat? Xda experts are saying it's bootloader is locked

This is a strange one I used to have the opposite. 4.4.4 every now and then touch screen stopped responding. Pressing power resolved it.
When I upgraded to LL the problem went away.
However I mostly use custom builds. At the moment the best for me is PhoeniX ROM.
Absolutely bug free so far.
Can't say I had any issues with Ironrom either.

I'm running BlissStalk (discontinued) but I haven't had any issues with it. I was running the CM11 unofficial also without issues. But the stock 5.0.2 it had on it when I purchased it (used) had issues. All my devices eventually end up with a custom rom eventually!

I flashed stock kitkat firmware via Odin... But it is a different tablet than yours (SM-T800). I found the following thread when I was trying to do it. Just make sure you flash the firmware for your specific model.
http://forum.xda-developers.com/galaxy-tab-s/help/sm-t800-best-to-downgrade-5-0-2-to-t3069929
Bootloader unlocking
So basically searching around the internet to find a kitkat firmware for this. I think it can be downgraded but I need the stock firmware for the sm-t807v.
XDA forums have support for the other variants but for the one I have which is Verizons sm-t807v there are no STOCK firmwares anywhere.
Ashyx and steve if you know any resource, please help me out. I need to get this fixed. I don't have access to any verizon stores where I could go and get this fixed or sorted. It just me and the internet.
I need some help guys. I received the OTA update from Sprint with my stock firmware and it totally made my phone unusable. It keeps freezing and then rebooting. I have tried everything i can think of but nothing helps.
I did i full factory reset about 3 times. 2x with the zerolemon battery i was using for the last 2 years. Then another factory reset using the stock battery that came with the phone, which didn't get used more than about 5 recharge cycles before I replaced it with the zerolemon one.
After that I thought i could undo the patch but as you guys know the QI5 firmware is not backward compatible so am i kind of screwed? I have tried rooting and loading a custom rom, the CMDMOTO is the only one I tried since it seemed to work for others using the Qi5, but i still have the same issue.
I am a bit new to the rooting world but i have been reading up to figure out my problem, any suggestions? I have TWRP, super user and titanium backup.
Thanks
Work around FOUND !
Installing the app 'Wake Lock' and using level 4 'PARTIAL_WAKE_LOCK' seems to have made everything better. I will keep this thread updated if something else happens. I guess for some reason the last patch changed something that made the cpu go inactive or sleep much more frequently or something like that.
If anyone knows how to correct this let me know. It seems that this was actually a very common problem with the other variants of the note 4 it just took a while to get to this version. I wonder if anyone else was having this issue with the N910P.
Cheers
Have you tried booting to recovery and wiping the cache partition? If it falls asleep and freezes that points to a kernel issue if I'm not mistaken. Wiping cache will NOT delete any of your data. Hold Volume Up, Home, and power til the phone turns on and you see some yellow/blue/red text in the upper left corner then release. Try wiping cache and see if it helps

When I did the factory wipe from the 3rd time onward I always wiped the cache and all other options that were available. As long as i keep the wakelock app active the phone does not freeze up and/or shut down but it is draining my battery pretty fast. I am thinking it has something to do with the phone going to deep sleep and unable to come out of it properly. I am playing around with 'Kernel Auditor ' to see if i can find a setting that will fix this issue. I am almost convinced it has something to do with the cpu clock states and Deep sleep not working correctly anymore.
I personally am a fan of 3c Toolbox for most of my diagnostic needs. Theres a free version available, check under the cpu manager tab for whatever info is relevant to you. Example..it will tell you live cpu frequencies/load, live power usage, wakelocks, all sorts of goodies
Have you tried to ODIN a factory .tar image?
sammobile dot com has the QI5 image. Just make sure tou grab the sprint one and not the unknown carrier version.

Thank you so much for posting this work around! My Wife's Note 4 has been working great for over a year, she bought it used. Then a few weeks ago a bunch of updates were pushed to it and it just started to act up.
I narrowed it down to always occurring after the phone was idle for more then an hour or so and started to look for a clue if this may be a known issue so your work around makes a lot of sense.
It does appear to be an issue with Googles 6.0.1 OS version since my BlackBerry Key 1 also received a bunch of updates but its fine.
Ever since I updated to 8.0 last week I have had to reboot the phone on a daily sometimes twice daily basis because all the sounds randomly become very low even though the volume for all sounds is at max. Very irritating. Anyone else experience this issue?
i have this exact same issue on my device i did a factory reset and it did not go away. this is why they need to unlock the bootloader so we can fix our our issues. im working on a flash script that i will test since i have others i can use if i need to rma this device.
You would think others will be chiming in here shortly after they update. I doubt we are the only ones that will notice this issue. I would hope and expect MOTO/Lenovo to push an update out to fix this and any other issues that may have been noticed in the Oreo update. This I can at least live with as annoying as it is, Unlike my issue with my GEAR S3 Frontier no longer charging post the Tizen 3.0 update!!!! Samsung has yet to address this bug rendering this product useless for now.
i called at&t and they are replacing the device since they dont have a way to revert the software or unlock the boot loader to allow me to fix this my self. once my rma shows up i will be doing some very risky mods to the device. lets see if we can get some traction on this device.

T-Mobile variant here. I notice this randomly too. As best I can recall it only occurs when I disconnect my Bluetooth headphones. Toggling Bluetooth on the phone seems to reset volume levels.

Nice! I will try this next time it happens- Much better than rebooting each time.

I tried it and it worked! Much better than having to reboot the phone everytime the volume takes a dump.
Good to hear it works for you as well. Maybe Moto will fix that bug in the next update, there is a lot of talk on the Lenovo forums about Bluetooth issues since the Oreo update.
Hey guys, I have updated to Android 10 from quite a sometime now(was a beta tester) and was noticing that device practically become usable after a few days of usage. Keyboard stops popping up, apps get killed in background and so on..
This issue gets fixed by a restart though. Has anyone else noticed something similar?
I am also facing issues after Android 10 update. Please let me know if you find permanent fix or solution.
Yes, same here. I reverted back to Pie. I thought I was the only one!

Nope, you are not alone :crying:
i can confirm the exact same issue since OTA update to Android 10 on S9 (DBT). currently with second minor Update to DTAD build problem still there. Tried different things to work around but yet nothing helped. i assume it has something to do with memory leak on swap partition. memoryinfo & swapcheck app always show 0 byte free swap memory which cannot be freed again when this occurs. As stated before, only reset phone helps, but after 24h its the same. struggling with this since the first Q Update Version. Any suggestions highly appreciated.

Auto-restart every morning
I didn't find any issue, and I didn't factory reset my device after installing the update. My phone runs quite smoothly, no issues whatsoever.
The only minor bug is that the transition animation of the clock from the lock screen to the always on display is laggy, and sometimes the instructions like "hold your phone more upright" get stuck on the always on display. I hope this will get fixed in the next update.
@icoolguy1995
any news on this issue? Perhaps it's any app or launcher or tool some of us use in common, since it seems not everyone is affected. i have to admit, that i have really a ton of apps on my device and freqently use it. But I already had the same conditions on Pie and there never run in this lag problem,so....

Well I am still researching about this issue. I reported this issue couple of times to Samsung during beta testing; they said, they are unable to reproduce this issue neither they are able to see it on logs which I have sent. For me, the issue starts to appear after 91 hours of usage without a restart. Weirdly, using any keyboard other than Samsung Keyboard seems to help somewhat. I tried using Gboard and the issue somewhat mitigated but still annoying enough.

I have reflash the firmware because it was getting unbearable. It's been 3 days, no issues yet. Will keep you guys updated.

Same issue here. After android 10 update it's laggy as hell. Android auto crashes randomly. Spotify stops working..

No effect of reflashing. Same issue popup up after 4-5 days. I wonder if this is more like a hardware related issue then software?
No, i don't think so.
Got a new update, it made issue worse. Now, instead of 90 hours free of system killing spree I am getting 70 around-ish hours with good ram management. So my workaround for this is now to set auto restart in 3 days interval.

Hey guys i am having very much lagging problem in my phone. After my current miui virsion is miui 13.0.3.0 stable version.. can i claim warranty on this problem!!? I have bought my phone recently. Thnx in advance.
Hello,
If the phone has defects, the warranty should be taken into account. On the other hand, if the phone works well, especially the hardware, I think that sending it under warranty is not necessarily the right solution. Have you reset your phone since installing your update to MIUI 13?
Bill
i'm having the same problem, i see that very often the system start to lag when it have about 1GB of free ram. Then the camera slow down and the launcher sometimes crash. Closing all the app frees only some 100s MB, the only way is reboot the phone. I'm thinking about moving to xiaomi.eu rom
Definitely warranty. It's a phone. It has electronics inside. Just RMA the phone.
Mine does not have any lag, freeze, issue. It's the most stable, long-lasting phone I ever used.
The only "issue" I ever saw/had is the lack of OIS on the camera, but that's 100% hardware. Xiaomi loves saving pennies on camera all the time. (See Xiaomi 11T Pro)
Ps.: I've tried stock, Xiaomi EU Stable and Weekly; all with ram boost enabled and disabled. No lag whatsoever.

No lag even after 3/4 days without rebooting?
In a German forum someone could solve this problem by turning off that 2 GB memory extension in settings (turning it off is a good idea anyway).

When I saw that option turned on I disabled it immediately. No luck, still lagging
Some users on 4pda reported similar problems.
The solution - do not use custom themes, only pre-installed.
Classic/Boundless.
Proof link
Deepl.com translate:
"Can be happy with the phone today, holds 86% by the end of the day, nothing hangs and camera instantly on. Delete all the themes except for two "Classic" and "Boundless". I have Boundless, the phone does not recognize, but the other day I already wanted to throw it away for his stupidity. To understand - I have a phone so consumed the charge that the car when the navigator mode, he discharged even with the charging cord, and if you turn on the camera while the navigator, you have to wait for about 15 seconds. In short, I just realized for myself - it's crooked theme it so stupid!"

I totally agree.
I had the same problem. What I did is reset the camera app settings and set it to autostart(saw it in a video) which fixed camera lag issue to some extent. Also there is an option to schedule shutting down of device, so I scheduled it to turn off and turn on in a couple of minutes just before my alarm goes off in the morning. The phone runs smooth like butter throughout the day!
