Hi all,
I bought 2 units of SGN2 recently and found out that sometimes during from sleep to awake or from lock screen to unlock screen, there is a line of white light flashes across my screen horizontally at the bottom just above the home button. To be sure on the problem, I had tried out 4 more units of SGN2. 2 from my friends and 2 from shops display units and they all having same symptoms. Had sent back to Samsung service center and they had my phone formatted and reloaded software. Also done a full factory reset but still not resolve. Does anyone else seeing this symptoms? Is this a software issue? by the way, my phone is not rooted and still using original stock rom 4.1.1 Jelly bean.
Please advice. ...
Thanks

wow, thought I was the only one experiencing this. Hope there's an update on this one. Will try calling Samsung about this.
Me too
Hi,
Had try not using the ripple effects. Its the same. However, I had raised this issue to Samsung and their service personnel replied to me that it was a software issue. Ask me to wait for next software update. Anyone who has this same issue should highlight to Samsung too. Hope there is a fast fixed.

Same here and it is not happening very often...
I'm facing the same issue and now it is happening very often... I believe they samsung need to do some thing about it..

I have to say, my phone died 2 years after. Exactly that.
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.
Shot in the dark I guess but since I got this device, Snapchat has been terribly laggy and almost unusable. Specifically when using the keyboard for text. Sometimes when I launch it, the camera is just black for roughly 5 seconds and then the back camera comes on finally. The chat feature is very slow at times and the entire app seems to stall and crash at least once a day. Anyone else notice this?
A quick google search yielded several recent topics on various forums complaining about the same thing, all on 6.0 Marshmallow. Hopefully it's not just this device.
I'm getting this exact thing
I went through that too. Once I had to restart it to make the camera work again. My tip is do not try use volume keys until it load completely. It just frozen the app in a black screen. Isn't perfect but can be used.
It's probably not optimized as well for 6.0 yet
Snapchat hasn't been perfect for me, but I've never experienced any of those issues. The worst I get is a little delay when pressing the home button.

I have had this problem we will have to wait for an update!! Basically that's what I've been telling myself lately about marshmallow

I can tell you guys I had this problem on my Nexus 6 on Marshmallow, it has to be something related to 6.0, I'm on a LG G4 now and snapchat runs just fine.
Kinda laggy for me too. And I can't get it to play a notification sound when I recieve snaps. I have turned it on in settings and I get a notification as normal, but no sound. Does anyone else have this problem?
Just uninstalled it from the n5x will have to limit myself to using it on n72013 it was unusable. Crashes camera failed to load then started to affect the stock camera app, would cause system crashes and could only be sorted with a reboot.
Same here its completely horrible to use of this phone. Phone ****s itself every time I try use it!

The app has been perfectly fine for me, up until the update I got yesterday. Now I see exactly what everyone is talking about....it's completely unusable now.
Our of curiosity...are you guys all encrypted?

Ok never mind then. I've been decrypted since I got the phone, until I took an OTA recently. It's been crap since then, but I guess it's unrelated

Well again Snapchat just updated, and now I'm back to it working fine again....

The past few updates have been good for me luckily.. Just don't try to send a snap while in landscape, I tried to add text and Swiftkey went all wonky and overlayed the screen even after I pressed Home, had to force close Snapchat and Swiftkey both :/
me too I have same issues the lag and so slowly for texting and even after update marshmallow update 6.0.1 the problem still the same I hope can anyone help me with issue what should to do and thanks you
So I am a power snapchat user and had this same problem and might have accidentally stumbled on a possible solution after having a login failure. I enabled the travel mode so it's not downloading constantly. I installed snapprefs and I can't explain why but it's flying now. No lag on window switching or opening the camera. I'm on 6.0.1 December rooted
Everytime I take video from Snapchat, it produces the sound "dug" at the first second of the video, never put my finger too hard on the phone so it isn't bcs of my finger knocking the screen, anybody know why?

Hey guys,
Somehow I managed to make my H815T working by following ILAPO method by blueeyeblue. And it was working quite well for a few days. Then suddenly from today morning, it started automation touch problem as it someone is constantly tapping on the screen. The problem was so bad that it became unusable. Yes I removed the screen protector also, but it didn't solve the issue. Does anyone have this experience?

Hi, I was wondering if anyone else had similar issue. I have been using android smartphones for years now and since always I've been using custom roms. But never actually happen to get issue like this on Lenovo P2.
Problem description:
When device is unlocked. After some time the screen is ON it starts touching by itself at the middle of the screen.
Always the same spot. It doesn't matter if I'm using my phone at that moment or not, touchscreen can touch itself while I'm using it and it interrupts my usage.
I am not using any modifications. Only lineage root is installed. The problem started after installing Lineage OS official build, one of the first 5 builds, and continues to happen till now.
Here are the videos showing how does it look like.

Try stock ROM again, if it still happens, your display has a hardware issue
