weird screen took over my phone after update - Sprint Samsung Galaxy S7 Edge Questions & Answers

My phone updated to build APL6 this morning, when it finished it was just black with an installing applications screen. None of the buttons worked. I was finally able to double tap the home key to open the camera, take a picture and then view it. Swiping over allowed me to finally get to the lock screen but it would just unlocked back to the same screen. I eventually fixed it doing that over and over while trying to get into the recent app window. Just wondering if anybody else knows what it is or has experienced this before.

Happened to me too. Eventually it finished but took a while.

Today screen problem

For the last few weeks I have been experiencing a problem with the today screen in that it randomly disappears. Clicking on today from the start menu does nothing and the only way to get the screen back is to do a soft reboot. I installed the new o2 rom update hoping that this would clear my device and resolve the issue but within a couple of hours it happened again. I suspect that it may be caused by either calander+ or the magic button application but I cannot be sure. Has anyone else had this problem or got any ideas how to resolve it?
I got the same problem now and then.
I got the feeling is had something do to with Magic Button (a closer app). Just removed it - and now waiting for the thing to appear again (or not)
I think you're right. I've removed it too now. Fingers crossed!!

Automatically reverting back to start screen

Hi, I hope this is where I ask a new question. My HTC Snap had been working perfectly up until last this morning. Whenever I go to any app (i.e. PIE, Mail, Start button, etc.) my Snap reverts back to the home screen as if I had tapped on the back key, but this does it by itself after a about 15 seconds.
It never did that before. The last thing I installed yesterday was the TCPMP player, but I don't have any other type of mods on my phone beyond the install of a few apps, and again it was working fine last night.
Tried soft reset, but issue is still there. Afraid to do a hard reset thinking that will deleted everything including Sprint added apps.
Has anyone experience this? I want it to stay in the program until I decide to close it. It's now a pain when loading web pages and it jumps back to the home page. Help please from the experts!
**** UPDATE: RESOLVED ****
I found the issue. Somehow the Home Screen setting was set to 10 seconds. Bumped it up to 5 minutes.

Erratic/laggy touchscreen performance

I've been getting very strange/unwanted touchscreen issues for a while now. It seems to happen randomly and for hours at a time. When I press the power button to wake the phone and turn the screen on, I can't even drag the unlock slider to unlock the phone. It takes numerous wake/sleep power button presses until I can get the screen to respond to my finger. Sometimes I'll be typing and it will go crazy and highlight buttons back and forth quickly, usually two or three letters almost always off to the left side of the screen. When this happens I am unable to get it to stop or register any other screen presses. I have to press the power button and then press it again to wake it and I'm stuck at the unlockable lock screen. Only after repeated attempts does it finally get through and the problem will go away for a while, only to come back later.
I have used the program 'Dotty' to track the touch points and I noticed that it will sometimes show a multicolored touch point off to the left of the screen and it will jump around, and it won't detect any other new touch points.
Soooo I think my screen touch sensor is messed up somehow. Does anyone else have this happen? Seems to have started when I flashed the kernel to get rid of the 30 fps cap. I have recently flashed Fresh 3.1.0.1 and still have this problem, different kernel with that rom correct? I'll try to get a video up sometime to show this in action...
Yes, I've been having the exact same issue. I even did a hard reset, with the assumption that it was an app. My plan was to add them back slowly until I got the issue, the problem was it happened as soon as the phone rebooted on the reflash. I have no idea what the issue is, but its very frustrating.
I'm running 2.2 stock...
Some people have reported touch screen problems with netarchy's kernel. There is usually a revision to correct this problem for people who are experiencing it. I suggest you carefully read over the OP in that thread and determine what kernel is right for you. There is usually a version specifically for Fresh users also.
MIGHT i ask what widgets are you running??
i talked about it before when running the pre-official ota rom.
it was my htc music widget (half sized one) i had running on the home screen.. caused lag like a mofo, couldnt swipe most of the time, capacitive buttons wouldnt react, pressing the app drawer button wouldnt respond till 5 seconds later...
AS A MATTER OF FACT.
im running fresh 3.1.0.1 + latest kernel + music widget on home screen.. LAAAGGG like before. removing it makes things snappier again.
YEP. Its happening again.
when i ran the STOCK Official rooted rom, with music widget on home screen didnt produce this lag and poor touch input, even with kernel it didnt produce this problem.
Mine is fine, no screen problems!!! stock rooted rom!!

Top part of screen stops responding to touch occasionally

After a while the top part of my screen will completely stop responding to touch. I can't pull down the notification area or press anything on the upper portion of the phone. After, I reboot it works for about 30 seconds and then the top part of the screen will stop working again. The only thing that will fix it is to wait it out. Maybe a few hours later it will start working again. Then a couple days later and the same thing happens. I think maybe my phone is overheating from some app or something and then it causes this to happen for some reason. That would I guess explain why it starts working after while, because the phone had a chance to cool off
Anybody else experience this?
Yes your not alone with this issue.
This happened to my galaxy S8 plus after using twitter.
I uninstalled the app but I hadn't regained the ability of touch response.
I don't have a backup device but have ordered an older model so that I can further diagnose.
In the meantime I found an app to help counteract the problem. ie. Rotation - Orientation Manager
To be clear this is the top portion of the screen from Very top to about a half inch down.
I verified by using a touch sensor test app. ie. Yet Another MultiTouch Test
I've also did the soft reset, clear cache, and since I use a third party Home Launcher reinstalled it. ie. Nova Launcher Prime
Good luck!

Home button unresponsive, lock screen comes on by itself.

Update: So today at work it decided to behave seemingly out of the blue.
Heya,
So I have a problem with my Note 4 that I just cannot figure out this time around. I found that the lock screen was turning itself on even when left alone on a table and on top of that the home button is not working. After I installed a security update I had put off installing the home button worked again for about 10 minutes or so. I figured it was a software problem so opted to factory reset the device. No problem getting into the recovery menu by holding power and volume up.
Once that was done though the problem persisted. I'm inclined to think it's hardware but I figured before I throw down money on parts I'd get a second opinion just in case I'm missing something.
It's a N910-P running 6.0.1 and April's security update. Any ideas/suggestions would be appreciated.
Thanks!
My device is doing exactly the same thing all of a sudden... Seeing a few other threads with similar issues... I'm guessing a Google Play Services update, as the play store icon changed just about when it happened...
