Tab S (VZW) loses touchscreen sometimes - Galaxy Tab S Q&A, Help & Troubleshooting

I have a Verizon Tab S 10.5, which has been working fine for months. Now, I'm experiencing random times where the touchscreen is unresponsive. The physical buttons still work, and the bluetooth keyboard still works too.
If I press the power button, then unlock it, the touchscreen works again.
Has anyone else experienced this?
I love the tablet otherwise.

I have the 8.4 and am experiencing the same difficulty. I usually use a stylus and suddenly, the same stylus on the same page of the same site, isn't responded to. I push harder but that never works. I find that using my finger, even for one response often brings back functionality. I've been wondering about the screen protector and whether that gets old or something. Are you using a screen protector?

No, I don't have a screen protector on it. It is in a Logitech keyboard case. Do you use a case?

tab s 10.5 touchscreen unresponsive
I am having the same problem with my tab. At seemingly random moments my touchscreen becomes unresponsive. The home button works but nothing on screen is responsive until I hit the power button, putting it to sleep briefly and then hitting it again to wake it up. At that point the touchscreen becomes responsive again.
I sure hope someone finds a solution.I love my tab but this is a bummer.

Content screen unresponsive
The content screen has suddenly become unresponsive, none of the windows will open or refresh. The other home screens are working, just not the content screen. Any suggestions please?

What firmware are you guy`s using, are you still on stock 4.4.2 or on stock 5.0.2 or something custom.
John.

Hi John
I'm using 5.0.2. I've tried restarting and a soft reset and the other screens/apps work fine, just the content screen.
Jill

I had a search for Samsung touchscreen problems, most were down to the touchscreen connector coming loose due to a drop or flexing of the case, a hard reset sometimes works, a battery pull sometimes works, somebody said he flashed to another firmware and that fixed the problem, but if you are on the stock firmware that cannot be the problem, or is it the new 5.0.2 firmware?
Have you tried a touchscreen tester app ???

John.

It's a pretty new tablet so I guess it's the new 5.0.2 firmware. It's only unresponsive on the content screen so it seems like it's to do with that software - would you think. I don't know how to get at that though. It's Samsung thing and there are no settings for it, it's a bit like blinkfeed on an HTC only it doesn't work!
But thanks for the link, I'll try a touchscreen app anyway. A screenshot is attached hopefully.
Thanks for your help.

Ok, a list of owners affected and tablet models and firmware version, can you give your details so we can get some pattern?
golden422 - 10.5" - need firmware version
mlg250 - 8.4" - need firmware version
dbarkett - 10.5" - need firmware version
jgordon5 - 8.4" T700 - v5.0.2

Galaxy tab s SM-T700 8.4 v5.0.2
Thanks.

Strangely enough i installed nova launcher, didn't like it so uninstalled it and then the content screens started working and are now responsive!

I have the same problem with my SM-T807, running 5.0.2
Any luck on finding a fix?

My touchscreen was only not working on the two home screens where you choose your own widgets. I installed a different launcher, didn't like it and so uninstalled it and then very strangely those two home screens became responsive. Weird!

Huge problem with gyroscope, please help.

As title.
Since many days my gyroscope is going mad.
If I leave the phone motionless, on a table for example, the gyroscope does not remain stationary, it moves.
I tryed the free app from the market GyroRotate, I leave the phone on the table, and the cube moves by itself. This make games like battlefield unplayable.
I'm experiencing this problem since some days, why?
I have the stock rom. Are you experiencing the same problem?
Can you try the GyroRotate app please and tell me if your cube moves if you leave the phone on the table?
Thanks.
Tested with that App and mine is fine. Have you tried the figure 8 movement to reset the gyro?

Mine also works as expected.
Thanks to all. Now is fine here also.
A battery pull solved the problem.
Neither a reboot solved before the battery pull.
My phone takes 4-5 seconds to switch from landscape and portrait and I am having the same issue with games from time to time. I am still incredibly surprised and annoyed that they did not include a "calibration" option in settings.
Mine still has roughly a 2 second lag when rotating. Today when playing a game that you can rotate to landscape on either side it keeps flipping itself as though I'm holding the phone upside down...argh...so frustrating.
I tried the figure 8 now and if that doesn't help then I did a battery pull
I tried to find the GyroRotate app but it doesn't exist on the android market.
Still having issues.
I have the same problem I wonder if the games are messed up, because the app "gyroscope rotate" works fine.
But Brothers in arms 2 (free app) it's moving to the right by itself.
Can someone else try this game?
Also Asphalt 6 is messed up too.

pull battery didn't help..
same problem here, tried battery pull with phone turned off and then turned on, but still neither worked. Don't understand what "8 movement" people are talking about. Is any way I can solve this problem ??? I want to use google cardboard on my galaxy s4 but it goes to one side alone slowly -.-
Goggle Cardboard problem
Hi, I have the same problem with realy slowly movement of sreen in Google Cardboard app. I have tested my gyroscope with other app and it is very accurate. Any suggestions how to fix it
Same problem with Samsung Galaxy S3, after shaking the phone the movement changes direction for a while. This problem is really visible in virtual reality apps. What can be done to fix this? Any help is really appreciated!
Same problem here with the galaxy note 3. The cardboard app is impossible to enjoy and also photospheres are moving left by their own. Could it be an hardware problem? Has anyone found a fix?
Here is the solution that worked for my Samsung Galaxy S4:
1. Open Phone app
2. Tap on Kepad tab
3. Type *#0*#
4. Tap on Sensor
5. Put your phone on a flat surface
6. Tap on Gyro selftest button
7. After the PASS message, tap the back button until you exit on the homescreen.
That's it! Hope this helps you guys.

Strange screen behaviour

Hi all.
I have p-601 which is rooted and I am using Nova Launcher. It works fine except of some lag from time to time.
I use the S-pen for everything and with all applications.
Recently I started to notice strange bizarre behavior of the screen with the S-Pen when I capture a screen shot with the S-Pen (Screen Write) some pictures specially with the png format. The screen flashes and displays a horizontal lines then the screen turns off. Then I close everything and reboot the tab and try again to screen write and so on.
This happens from time to time not with every screen write.
Any recommendations or advice?
Best Regards.
I'd do a hard reset in recovery if it bothers you that bad. And if you have any mods running try it with out those installed a few times and do some testing to see what is causing the issue. But start fresh, stock and if it still happens its your device. Either return it, if u can't return it sell it, or just deal with it and wait for an update.

Very strange issues with my M8

I've been using unlocked international M8 for more than 5 months, and I've never had any problems.
Few days ago I updated it to 4.4.4, and everything worked perfectly. But today I've noticed some strange issuses.
1. Screen turns on by itself
2. Auto-rotation is off, but screen is still rotating in every angle (including 180). I can even rotate screen on lockscreen, home screen or app list.
3. I can't browse the web because pages are constantly refreshing them by themselfes.
Phone is fully stock, never rooted.
Anyone has similar problem? Or does anyone know why is this happening and how to solve it? Any help is appreciated.
Random bugs after an update can often be resolved by backing up your personal data and doing a factory reset.

T325 severe issues after update.

Well I got an ota update a few weeks back. Installed it and had issues with my tablet doing reboots all by its self. It would just shut down and restart and so on until I caught it and turned it off my self. Also some of my apps started freezing. Plus has some touch issues. Well got another update yesterday and now the tablet is pretty much useless. 90% of the screen touch doesn't work. I had reset it twice and its still the same. Now if you try to touch say the chrome app feom the home screen it doesn't register. Though if I open my apps and click on chrome there it works. So chrome is now open. Nothing on the screen works but if I open the recent apps the touch works perfectly there but I close the recent apps and again screen is unresponsive. Its also random. Sometimes stuff works and others don't.
What do you guys think needs to be done to get this to work. Paid $500 for this tablet 6 months ago so this one hurts a little not working.
Do you all know if the warranty is valid since I bought an international version

Warranty should be valid if you bought it in the same country, They sell international versions in major retail outlets like walmart / amazon so I'm sure its fine,
btw have you tried doing a factory reset under settings? (this will erase all your apps and settings but it should restore the tablet to stock condition, except it will retain all the OTA updates), I never suggest doing OTA updates as they can sometimes cause issues, even Samsung doesn't recommend it, I would suggest you update the tablet with KIES 3 (Samsung official software) or Odin
(for odin you can find the fimrware for your tablet here http://www.sammobile.com/firmwares/ ) Odin is a little more advanced the kies 3 but its what I always use to update, either one is fine.)
Did a factory reset and it didn't help. Will try update with kies and see if that works. Thank you for the suggestion. Hope it works

Reduced touch screen responsiveness after OTA 12.1.1.0(JRDMIXM)

Hi there,
I had gotten the OTA on my Mi 10T Pro some time back and since the update, I notice the screen responsiveness reduce a lot. I always missed the gesture to perform back or pull the notification status down or any other gesture.
I even notice my Capacitive Pen (fine tips) wasn't registering the touch too. Previously, it was working fine on my Mi 10T Pro.
Do you notice that too? Or it is only me?
I have the same problem with big lags on the touchscreen, or maybe big lags on the apps that freeze touchscreen changes.
I updated to 12.1.1 Global via an OTA a few weeks ago, but had to factory reset to get it working. Then it worked well, except for the very annoying lack of gesture support for non-stock launchers.
Now I get major lags scrolling through items or using swipe on the Google Keyboard. Very frustrating ,and I only hope the 12.5 update comes soon and fixes things.
Look like we are not alone.
You set to factory default fix the problem?
No, it's still lagging badly.
I had to Factory Reset to get the phone to work acceptably after the OTA to Android 11. It worked well for a couple of weeks, then started lagging badly with many apps involving a long swipe (like keyboard using swipe, scrolling through news etc) would become unresponsive after about 1/2 sec movement.
Reboots didn't seem to fix it but may have improved things for a while before returning to lag.
