Hi, sometimes when I try unlock my Xperia M, then I stay on black screen. Phone is in standby and I must pull out battery. This issue I have two times, maybe three times per day.
I dont know, it is CM11 bug? Any fix for this issue?

I have been having this problem since I installed cm11. I tried a lot of things and up till now i've gotten the best result with turning off the "agenda on lock screen". I'm now 36hours crash free.
I also installed the latest nightly. But I think the agenda causes the black screen on wake up.
edit: 60 hours
Hope this helps!!!
Hi there,
I was hoping you could give me some advice regarding an issue I've had for a while with my Tab S.
The screen is flickering occasionally and at times it causes the battery to drain very quickly and suddenly it reboots.
I have tried disabling hardware overlay option in the developer settings which seems to be suggested in many forums but that has not made much difference.
This has been getting gradually worse and now I am at a stage where after entering the PIN code to unlock the SIM the screen flashes a few times (white lines across the screen) and then the tab powers itself down.
I should add that I have root access and can flash roms if needed.
I believe the tablet was originally from United Arab Emirates but since I am in France I changed to a French stock rom. Before doing that the phone app kept crashing every time I missed a call...
Your help is greatly appreciated!

Well I have heard of this, but never seen it. Could you perhaps provide a video of the flickering? I guessing this is an firmware issue as people flashing lollipop said they saw this. The only thing I can think of is going back to KitKat or check if your on the latest update

Thanks for you reply.
I am actually on KitKat already, and going back to stock would mean issues with my phone app crashing when I miss a call.
Incompatible firmware seems likely but how do I know which firmware is right for my tab apart from trial and error?
Any other diagnostics? Changing CSC?
It sounds like a battery or loose connection problem to me, does the flickering happen when you move or slightly bend the tablet at all.
Have you tried the Samsung hidden codes to do an battery/hardware test.

I read a lot of people reseating the battery after having issues with battery draining, I might give this a go.
But before I open up my tab, are there any other diagnostics I can do, what are those codes for testing the phone?
Thanks
I have not tried any myself as you need a dialer and my T800 is wifi only, be careful what you are doing, there are loads of lists of secret codes.

You can use activity launcher from Adam Szakowski to lauch the hardware testing apps, just be careful what you launch, you can end with a wiped tablet.
I have now reseated the battery (disconnected and reconnected it) and so far so good!
No screen flickering and no random rebooting.
Thank you for your help!
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.

do you use some fancy animations and custom features?
you can try to change CPU while in standby mode, just turn it up by few hundreds and see if sth changes

no fancy animations or anything , this has been there since it was on stock and not even rooted ...
i have no idea how to increase CPU in standby mode ,
I am not sure if it is touch issue or display issue. https://www.youtube.com/watch?v=JdMbbML9ECg Please have a look at this link.
The touch works for 2 seconds of screen on. Anyone having same issue? Please reply if anyone has fixed this issue.
same problem.
It's like the smartphone, after a 2 second make a check then blocks the touch.
I noticed that if I touch the screen before turning on the smartphone, the touch does not hang after 2 seconds but after more than 2 minutes.
I'm not sure it's a hardware problem; I still believe that it can be solved by preventing the above control.

Which ROM and Kernel are you using? Should be a kernel related issue, try flashing a different ROM or Kernel.

I had the same. I used a piezoelectric of a lighter to give static shocks to the screen while touching it with the other finger. It worked.

I had the same issue, and fixed it by removing the screen protector. Now the touch has been working since yesterday

I am also facing the same problem on my phone.
I tried discharging the phone completely and charging again.
I use the original charger only.
I'm running Pixel Experience ROM on stock kernel. This problem started a week after unlocking and rooting my phone. I also feel that it is not a hardware issue.
The problem started with the nav. buttons: The rest of the screen functioned properly but the nav buttons were unresponsive. A little later (a few hours), the entire screen responded to touch intermittently, and after that it responded only a few seconds after unlocking the phone (the above mentioned problem).
I am having a very tough time as this is my daily driver and I'm stuck.
Please Help. Thanks a lot in advance.

This is exactly what has happened to me too. It started with the nav. buttons and then the rest of the screen. Have you found out what is to be done?
Guyz try a cell ,u know those 1.5 v cells use them as the s pen im not joking it really works u just try once
No solution whatsoever!! I just cannot believe this is a hardware problem. My screen works (most of the time) for 2mins if I wake the screen up while touching it with one of my fingers, otherwise the screen works only for 2 secs.
This problem has been discussed in very few places although there are many people who are affected. Loosing hope.
Can I exchange this phone on Filpkart/Amazon in India?

I exchanged my z2 plus with this problem on Amazon without any problem. They only want a phone which switches on and whose display is not cracked

Exactly how did you did that? Could you explain?
Broke a piezoelectric lighter and got the raw mechanism.
I made it discharge several times on the affected area while touching another area of the screen with another finger

Workaround
I tried one workaround indicated by someone else on another thread. Follow below steps
Press power button to put screen off
Hold phone in left hand and put left thumb on screen
Press power button to start screen
Touch with right hand fingers
It will work till left thumb is there on screen..
If touch is lost follow from step one
Atleast this helps alot instead of only 2-3secs stuff..
Thanks to one who indicated this workaround
Found a solution
Hi I was also facing this problem and I was ready to give up then I tried changing custom ROMs and when I installed the dot os v2.4,the problem disappeared and I was back to using the device normally
Hope this helps
