after sbf-ing with 2.4.330 the screen works fine for about 1 hour
then it went wrong again
So here is the issue. Tablet has been working fine. Last night i did encryption so i could use exchange email without root. I am not rooted, i did have the update installed. After encryption and my account was set up if the screen timed out or was turned off and back on, touch would not work and pen would not work. I had to power down by holding the power button. Once restarted the screen would work until the screen went off again. Then the same issue. I called samsung to see what they could tell me. They had me do a factory reset. After the reset while in the setup stage (touch working) i turned the screen off and on. The touch was dead again. They told me the unit was defective and to return it.
I know another user was having the same issues with the touch screen. I dont know if he was encrypted or not but unlike me he was rooted.
This also looks like it was a problem with the first galaxy tab.
Anyone else having this issue or have insite?

Starting to sound like Samsung changed the touchscreen driver between the original release and the update.
I KNOW the pen driver has been changing frequently, not sure if the main TS driver is.

Ok, My new tablet is working after encryption so far. I have not applied the update yet thought, a little scared to do so right now.

Argh, I just rooted my tablet after accepting the OTA yesterday and now my S Pen isn't working at all. This is bizarre.
Just reimage with ODIN if you can.
Whenever I lock my device, the touchscreen becomes unresponsive. I must restart the device after I lock it every time. the lockscreen only works the first time u use it. Even if I hold down the power button, none of these work and I must do a hard shutdown. Has anyone else had this problem. I am on stock, with one firmware update, unrooted. I have the US WiFi model.
Update: I have tried a no lock app which skips the touchscreen. This works, but when the screen is unlocked no touch input is accepted.
Search for Entropy's Odin flash , and reflash.

frozen lockscreen
That update has screwed up pen on many devices . Mine was like that too for a while . I have changed settings in stylus , disabling the pen detection , and after that when I remove pen touch does not work , when I put it back screen works again . I went back to the store and exchanged it for new device . Since I heard that samsung has pulled back that bad update , I tried to update and it is pulled back . But samsung is not doing the right thing . They should put old one as " update " so that people can fix their devices . Find and flash rooted UEALGB rom and you will be fine
I saw this behavior when battery was low. After charging it up the issue went away. This was after the update so that might've introduced the behavior. Another GN 10.1 without update doesn't do that.

This does not work. When I turn the screen back on no input is registered. I am going to fully charge it now.
Ok, i seemed to have found the problem. I was on vacation for the last 3 days, and I had forgotten my S-Pen at home. On the last night I began encountering these problems. I have just gotten home and was able to test the tab with the S-Pen and it was not accepting the S-Pen input at all. I restarted the tablet, with the S-Pen in its holder this. Now everything works perfect! This was very strange but I am glad that it is working now. Thank you all for your help.
So basically, around 2-3 weeks ago my phone's screen started acting up. Usually it'd take me two tries when turning the screen on to actually get the touch screen working. As in, I turned the screen off, the touch screen doesn't register any touches, then I shut the screen down and try again, and it sometimes works. Now, this didn't bother me - I though, maybe there's some short circuiting, it may fix itself. Fast forward 2 days later. my touch screen now needs minimum 3 tries to work, up to 9 or 10 sometimes. Note that when my touchscreen starts working, it works without a problem, all 5 fingers until the screen is shut down. Then I did something that COMPLETELY broke it - I restarted my phone. The touch screen never worked then. Like ever. I could try 100 times and it wouldn't work. I'd take out the battery, let it reset nice and **** - it doesn't work. So the next thing I did was a factory reset in recovery - the phone is restored to functionality before restarting it. Now, I didn't shut down my phone for 2 weeks, nor did it run out of battery - it's the same. Today, I've restarted it and the same problem occurred again - touchscreen completely unresponsive. So, I did the same thing as before, only this time I tested dalvik-cache and cache separately - none worked in any combination without a factory reset - at this point, I'm already certain the problem is in the software, and not the hardware. So, guess what - phone was restored to functionality with 2-3 tries after that reset. Then - an even more peculiar thing - I've enabled the touch gestures to turn on a screen. Most of the time when the screen turns on with a double tap, the password screen reacts to touch, but there are cases when I double tap, it opens, and then it doesn't work - it doesn't register touches. Most of the time, though, it doesn't even open the screen through the double tap. I've also noticed that it would sometimes happen when running - for an example, I play a lot of Cytus and Deemo - whenever there would be a break of more than 2 seconds between taps, if I didn't tap in between (so, when there are no beats to hit), it would sometimes completely ignore the next tap, as if the digitizer turned its touch detection off due to inactivity...
At this point, I have no idea what it is. I know that it's not the proximity sensor which I had originally suspected, and I know that the problem lies somewhere inside Android data folders or something a factory reset wipes. However, I have no idea where. My phone has been rooted and runs xposed, although I haven't used it since the reset - I wanted to flash a custom rom but found none other than Mstars 5.0 fresh install ROM. So, if anyone recognizes this problem, can I fix it with a new ROM flashed? Can I fix it by finding the **** that's causing this and always delete it at startup via script? Or should I just attempt to fix my phone in a repair shop?

Hello guys,
This is not necessarily a specific S8 plus thread, it's more of a software/hardware general related issue. I just replaced my display two weeks ago because I cracked the screen and the display a while ago.
After replacement, I got the phone, everything was good until I dialed *#0*# and started testing the touch. It appears that theres a portion in the middle of the display that is not working (the boxes wont go green when touching them). The thing is that, sometimes, the touch passes this test as in everything is ok and sometimes, it fails.
From time to time(pretty frequent) it randomly freezes and I have to hit the power button to open and close the screen to make it work again.
I just flashed the android Pie hoping a complete erase would fix the thing but it appears it didn't. Do you guys know any solution to my issue besides returning the phone in the service?
Thanks!
