Are you on a stock rom or custom? Have you tried doing a factory reset to see if it fixes the issue? If you are unrooted/stock have you tried asking Samsung about the issue? Read in other forums that draining the battery on the tablet until dead and then letting it charge to 100% without turning it on or using it fixes some touch issues but no idea if this works.
If all else fails might want to think about upgrading to the official 4.4.2 release (if there is one for the 5120 but assuming there is) and see if the issue still exists.

It could be that the tablet is not detecting the Spen properly... as if your case or screen protector is doing something odd.
I run Xposed Framework... even though it works well, I find bugs with its plug ins... so every once in a while I disable xposed to fix an issue in the settings by toggling the parameter for the troubled function and enabling framework before rebooting.

Hi,
Thanks for the replies.
I'm not using any custom ROM. I'll try with Samsung corp. Meantime if anyone knows a solution or a workaround then much more appreciated.
Cheers,
Karu.

Icecoldsandwich 8.4 and 8.5

I've been using 8.4 since release as it is so far the only version that has allowed my GPS to work for more than 2 minutes. 8.3 and now 8.5 both get a lock in seconds but then loose lock and search until I turn GPS off and on again or restart the app using GPS. I have fastfix installed and working but only 8.4 will work. My question is can anyone tell me a radio that works with 8.5 and the soon to be released 8.6? I'm also getting the 1-2 second silence on 8.4 when a call connects so really would like to update ASAP.
Many thanks to anyone who can help out,
James

If your on at&t try the new radio that just came out (.11) I also tried radio (.19) which seemed pretty good to me. But radios are based on your region not on rom.

I'm over in the UK and on T-Mobile, I'm currently using 26.14.04.28_M Maybe just testing a few out is the way forward...
Thanks for your reply
Update:
Just installed 26.16.04.09 radio and reflashed 8.5, I get lock within 2 seconds and permanent loss (searching) after about 2 minutes. back to 8.4 I go...
I've now tried:
26.13.04.19_M
26.14.04.28_M
26.16.04.09
26.09.04.11_M2 (now current as signal + GPS seemed to be quicker and better than the other radios)
With all the above on 8.5 GPS would lock then slowly start drawing a larger and larger blue circle around my position in Google Navigation until searching appeared and stayed. It seems like the ROM is the issue to to me, some way it handle the data passed to it? In 8.4 the indication of lock (the circle with the dot in the center) appears to have lost the sat lock, but the software is able to continue giving a near perfect lock of it's global position. In 8.5 I notice the software gives up around the same time that the phone starts to indicate it has lost lock. Could that be the issue? 8.4 ignores the instruction that GPS is lost and 8.5 goes along with the data passed to it? Sounds odd but it seems that is what is going on...
Does anyone else get this? or do I just give up and get a new phone...

[Q] Caller Screen turns blank, doesn't wake up anymore

Hi,
I got my Nexus a few days ago and I am quite happy with it - JB update worked immediately like a charm and it's a joy how fast everything works ...
But there is one pain point I encountered. While taking calls or calling someone the screen blanks, probably because of the proximity sensor. So far so good - but it doesn't turn on again. Then I am not able use any on screen controls, especially calling hotlines that require you to dial specific numbers while calling this behaviour is very frustrating.
I found a workaround, to setup the power button to cancel ongoing calls - this way I am able to hang up at least.
Is this a known behaviour, are there any solutions or other workarounds or am I the only one encountering this problem?
P.S.: I am running Stock Jelly Bean (4.1.1) / no root / no modifications
Am I the only one experiencing this behaviour? - any help would be gladly appreciated!

I have a friend with a Galaxy Nexus with the same problem. I'm wondering if you have found any solution to this or what was causing it?
This doesn't happen with my Nexus or my wife's
Either a busted proxymity sensor or a disconnected one
Under warranty ? exchange it
not under warranty ? Open it, make sure that the wires are plugged correctly. If it is and you still have the problem, replace the sensor
Hi, I haven't found a definitive solution for this issue
It just happens from time to time. Maybe the proximity sensor is kind of flaky?
I am using a combination of the Accessibility settings, pressing power button to hang up a call and screebl to keep the screen on. This works okay for me.
If you have any other intel regarding this, I'd gladly read it.
Cheers!

[Q] System performs some automatic actions even user doesn't use touch screen

Hi,
My galaxy grand touch screen digitizer was broken, so i have updated it new screen digitizer which i bought from local dealer(looks original but not sure it is original or duplicate). After changing the screen digitizer, some times phone automatically performs different actions.
when i turn on data roaming it used to perform different actions, without allowing user to perform anything(we need to turn off data roaming, then it works normally. I used to manage to turn off it).
So i thought it is a software issue and i have recently upgraded to 4.4.2 using cosmic ROM. But using this also i am facing same issue, im facing this intermittently.
does anybody faced same? is there any solution for this.

Hello...
I guess its duplicate....you could have given it to official Service Center?? Regarding Random Response it its possibly digitizer issue...Try differnet ROM and see if this continues then it is Digitizer Issue...

Tab S 10.1 Touch Screen Stops Working

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.

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.
