[Q] Touchscreen Issues

I purchased my NVIDIA tablet yesterday but having problems with the responsiveness coming from sleep. About 1/5 of the time, my tablet will not respond to my finger/stylus. I always have to press the power button a few times to get it to work.
I have all the updates, including the recent update from yesterday. Is this defective?
Thanks in advance

I've had that many times during one single day. Had to literally reboot the thing 5 or 6 times that day. COMPLETELY NO RESPONSE FROM THE SCREEN, ONLY BUTTONS. Still have to clue what the deal was. Hasn't done it since, but the issue DOES exist. And yes, I bought from the very first batch, straight from Nvidia.

I've had this problem since day one. Also the tab crashes at random times and it getting ****ing annoying. Thinking of returning the thing. It's worse than useless. Turn the screen off and you can bet that i'll have to reboot to get the touchscreen working again.
Idk why this helped but it did. I switched from using philz touch recovery to cwm recovery...now screen works less than half the time I turn it back on. That's still better than never.

I've never experienced this on Stock, Only on Pac-Man ROM and CM11. Either way it is very annoying.
This is a reaaallllllyy ghetto work around until the issue is solved, but the way I worked around it on CM11 is to have Tasker and Secure settings wake the device for a few seconds every 45 mins - 1 hour. Ever since I've had Tasker performing that task I've had no issues with the screen being unresponsive.

I have figured out how to fix the touchscreen issues. All you have to do is go under Settings>Apps>All Apps and find anything that ranges from Google Taiwanese or any Google foreign language app and disable it. There should be two of them. I haven't had any problems since I disabled them. :good:

I found something that has worked so far. I always use Nova launcher since it's my fav. I didn't think much of leaving the launcher that came with the rom. I went to titanium backup and froze the other launcher and it solved the touchscreen issue. This also fixed the app crashing problems most of the time. Still if I run more than two applications at the same time everything on the tab starts crashing. Seems to be a ram problem. I checked max backround processes and it's at "normal" which usually is fine. If anyone has a solution to the crash problem please let me know. Meanwhile i'll keep trying stuff.

Same problem here... Funnily enough I just wanted to try a custom rom to see whether this issue will be fixed and a new official upgrade to 7.0 came up - https://shield.nvidia.com/support/shield-tablet-k1/release-notes/1
Will see whether ithe problem is gone.

There was a time when my screen became a bit unresponsive. Very random. Calibrating the touch sensor fixed it up. Its a bit hidden but you'll find it by going into Settings>About Tablet (device)>Click on Model Number 3 times>The calibrating settings will pop up hit Touch then hit Start. It'll do it's thing and reboot. Hopefully it helps.

I had a similar issue with touchpoints not working near the corners, calibration fixed things for me also. It's pretty quick and easy to do so I urge you to try that before doing a factory reset.

So far so good... Android N seems to fix the problem

Screen randomly turns off but phone still on, backlight often stays on

Hey guys, i'll try to explain the situation as best i can below, hopefully someone can work out what is wrong.
My phone is about 16 months old. About 2 months ago i dropped it twice within the space of a couple weeks. There were a few cracks along the screen, however it wasn't very noticeable and i wasn't going to bother having it fixed. The problem started a couple of weeks ago when i went to grab it out of my pocket, however i found out the screen was black and it wouldn't turn on. I don't really know how to describe it but it was acting very strange...
- The screen would have white/gray bars all over it then turn off, then it would do the same with very thin vertical lines that were white/gray/other colours...
- When i get the screen on, it generally turns off again within 30 seconds, however it can stay on for a few minutes.
- If the screen is on and i press the lock button, it almost certainly won't come back on.
- Restarting the phone or holding the power and volume button nearly always gets the screen to come back on. It often then restarts but turns off again shortly after.
- The phone is otherwise still working when the screen goes off; the notification light stays on and i hear messages etc coming through
- The backlight often stays lit, revealing a gray screen opposed from total black. Sometimes it does not stay lit however.
- When the screen came on it was often unresponsive to touch
I had the screen replaced yesterday by a phone repair shop and the phone is still not right. I have factory reset the phone and also wiped the partition cache. Other than that it is still not working. IT seems to be working better... The screen always seems responsive to touch when it is on, and it doesn't seem to be turning off as often. It generally starts up and works fine when i start up by holding the power button and down volume button together... However even still it sometimes just flashes up with a few thick white/gray and black lines on the screen..
Does anyone know what can be causing this and how i can resolve it? If you need any more information please let me know and i will try provide it. I could try get some pictures of what the screen is doing when i finish work. Thanks guys, i appreciate any input.
EDIT: I managed to get a pic of what i mean by the thin vertical lines all over the screen. This just appeared when i tried to restart the phone after it the screen had once again stopped working. The imgur link is gIFMGD6

Anyone have any ideas?

Hey, did you ever figure this problem out? My phone just started doing the same thing. Can't find much info about it.

Yeah, i had the screen fixed hoping it would fix it, however that didn't work. Turns out it was the motherboard, don't know what was wrong with it in particular other than it was simply going faulty. Had someone replace the motherboard on it for $50 and have had zero problems since! Hope that helps you.

Thanks for the response. I tried replacing the screen too with no luck. Unfortunately the same place that replaced the screen said it would cost $400 to replace the motherboard!!! The phone cost less than that so it looks like I'm gonna buy a new one.

S6 Screen Glitched/Broken?

Hey guys. My wife's s6 just did something really weird and I have no idea how to fix it. Her screen seems to be glitched or messed up. I don't know how to describe it. When ever I turn the phone on the screen turns on for 2 secs but all the words and images are all over the screen and then the scree shuts off but the applications are still usable. I tried doing a restart but didn't work and I then tried upgrading it but also didn't work. I tried to kinda mess with the brightness but still nothing. We just got this phone like 3 weeks ago and it was working fine up to 20 mins ago. She hasn't dropped it or done any water damage. Can anyone please help me to see what is going on with this phone.
I cant provide photos because i am new user. If anyone know how i can get around this without posting 10 times let me know so i can show you the screen of my wifes phone. I posted a similar help post on android central with pictures if you need to see the screen.

You can try a full reset 1st. If it still persists then its most likely a factory defect. Return your S6 back to Samsung for warranty replacement.

Hi, Please try the following,
1. Open the dialer and hit *#0*#
2. There will be different color options like red/green/blue. select each one by one and check whether the issue comes up somehow.
3. Then try using the phone in safe mode/factory reset.
If the issue still persists, then it is likely to be a hardware issue and please get it checked with samsung as soon as possible. :good:

Which note edge's are affected by the soft reboot?

I was excited to remember this phone during looking at phones since I'm in the market for a new phone since my G4 died. But looking at a thread here it seemed a lot of people were having problems with soft reboots. Does this only affect rooted? or? is it for every verizon note edge? As nice as this phone is that might be a deal breaker for me. How long does a soft reboot take on the note edge? under 5 seconds? 10 seconds? longer? Just wondering in case I ever had an emergency how long I'd have to wait before I could call while it's doing it's soft reboot. And I hope it's not for every verizon note edge. But if it is how many times does it do it in a day for most? Meaning from about 8am-12midnight. Thanks guys.

Just do not use fingerprint lockscreen and no soft reboot at all.
How often occur? Good question, it depends on your habits. For me about 2 times per day. It last 5 sec, with laggy things 10-15 sec...
I am on 915FY btw not V.

On my 915FY it occured several times a day, and took sometimes more than a minute to get it working again. But fortunately I solved the problem with disabeling the stock-lockscreen and use hi locker instead. That app works with fingerprint and no reboots since then. All the other bugs (eg. loosing BT- or wifi-connection every now and then) seem to be related to exact the same lockscreen-bug and never appeared since that change.

Thanks guys, That helps me rest at ease.

Are there any other lock screen apps that work with the fingerprint scanner, i find hi locker temperamental.

I'm sure there are some, just browse through play store. What means "temperamental" in relation with an lockscreen-app?

I can't use Svoice while the screen is off, which is probably true of all lockscreen apps thinking about it.

I am using hi locker but still get the soft reboot in background....

Seems like it's every 20 mins... literally all the time.

Is this issue unique to the Note Edge, or does it happen with other Samsung phones?

What does soft reboot mean?
I'm wondering if this subject heading is the same as the problem I'm having on my notes edge... The phone goes off and tries to reboot even with 56% and at times with 70% battery left...
I'm desperately looking for a solution.

I had this problem. Every time the battery got down to about 60% the phone would cut off, try to reboot unsuccessfully a few times then die. Would not fully boot up until I put the phone on the charger. New battery solved it for me. Had this problem with another phone. Same thing. The battery was bad.

Thanks. I'm on this thread today because of an N915F crashing around the 40% battery full range. Unfortunately after it does that a few times it goes into boot loop that won't fix with cache wipes, and after a while it wouldn't fix with a reset either. It was still on KitKat, so I flashed 6.0.1 from September 2017 (Sammobile), but it crashed as well. Stepped back to July 2017 from Updato which updated to August 2017 through system update, and switched to a charger that will actually increase the charge on the phone while it's being used. Has been running fine while on the charger, but I also suspected a hardware issue since it would soft reboot on the recovery screen. Even though I have the battery at 100% now, I don't dare run it without the charger because I'm tired of going through setup and configuration over and over again. I ordered a battery last night. I hope that solves it for me too.

Use wakelock
select partial wake lock
and setting to start up on boot
its work on me never deepsleep in lock mode

I had same problem... Time for a new phone

S7 Edge freezing then restarting

Hi all,
Hope somebody can shed some light on this issue I'm facing. This is my first ever post. All your input will be very much appreciated.
I purchased this S7 Edge DUOS (Dual sim version) around 8 weeks ago. Around 3 weeks into my ownership, I've started facing a persistent issue which I've tried to resolve with the best of my knowledge but unfortunately I haven't succeeded.
Randomly the phone will freeze for around 5 to 10 seconds and then restart. Sometimes a pixelated set of lines would appear across the screen when it freezes, a lot of the times they are green.
When the phone does reboot and I return back to the main screen, everything is back to normal and the apps I was using remain opened in the background, so it's not a proper reboot.
There is no such pattern on when this happens, it happens while being used on any app and a lot of the times it reboots while the phone is in my pocket. The only reason I realise is because the phone will be on the startup lock screen.
Battery life seems okay, nothing seems to be draining the battery. Although sometimes it does get hot and drains it temporarily.
I have cleared cache partition, done a factory reset and deleted third party apps. Nothing has resolved the issue. When I did the factory reset, the phone didn't crash for a good few days then started doing it again.
I just cannot work out what it may be and it's getting really frustrating!
I really hope somebody can shed some light on this, I am trying to avoid going down the return route.
Many Thanks in advance for all your help.
Hassan

Hi my mate had the exact taste problem with his s7 Edge single dim version, it woody of freeze and reboot and pixilated just as u explained and turned out his phone his cpu overheated and this was the result of it, he then returned it to Samsung and he received a brand new handset so best is to maybe return it as it sounds to be a faulty handset.
