[C6903] Persistent problems with full screen and home bar, detailed info. - Xperia Z1 Q&A, Help & Troubleshooting

I updated my C6903 to Android 5.1.1 around... say a month ago? Or around there. It was giving me so much trouble, I couldn't stand to use my phone anymore.
Therefore, I read up on what I could, and attempted my first downgrade to 4.4 KitKat (Central European 01 version 108, unbranded). I didn't wipe the data and that turned into a bit of a mess, but I successfully flashed it and wiped the data properly during the second time around.
But I was still getting some problems, ones that had been occuring since my phone was upgraded to Lollipop. First, that my phone can not enter full screen at all, on any app. The home bar flickers on and off all the time, during Youtube, during any videos, during visualiser, or any app that will make use of fullscreen.
The second issue is that my home keys become unresponsive the vast majority of the time. Restarting does not fix this, and locking my screen then unlocking it again works for roughly 1 minute, then it's back to freezing and no response.
So, considering my main issues were persistent since the update of 5.1.1, I tried a factory reset. I wiped everything and flashed it properly again with Flashtool, to 4.4 KitKat.
It has not worked. Using the developer options/diagnostics I have tested my display and my entire screen has no dead pixels and reacts to the movement or touch of my finger with no issue. So if my screen is fine otherwise, why has 5.1.1 completely ****ed my phone over? It does not make any sense.
At this point I cannot even watch videos or do basic things on my phone as the above issues are preventing me from doing anything. I'm willing to provide as much information as I can, so I would appreciate some help and insight into this. Thank you!
EDIT: Additional information - Trying to view pictures in full screen (Album) ends up with it zooming in and out constantly, even when nothing on the screen is being touched.
When my phone is on landscape/full screen android keyboard, it will intermittently go crazy and start vibrating. I believe it is the symbol key being pressed on it's own, off/on constantly. Nothing on my phone is being touched or moved at this time, it just does this by itself.

it looks like some dirt got on the edges of the screen and it's messing with the touch detection.give that phone a nice bath(one of the best advantages it of being waterproof ) and clean that screen.that should fix it!

The cover for the charger port is broken and just fell off one day a long time ago (it never closed properly, though) so unfortunately, I won't be able to go through with that suggestion.

Added new information. I hope I can get some insight into this soon.

[Q] Did I get a virus ???

The video tells everything :
youtube . c o m/watch?v=Ay_eV9ycRZE
( Please modify the youtube . c o m to youtube.com , I cannot post url currently based on my forum level , sorry)
The thing is :
This is my second nook. My first one got the same bad thing just after I bought it in 2days, then I exchanged it to this second one.
I really don't know if this is a virus or something else :
It will not active always, it will active even I format system and data ( yes, rooted), it will active even I restore back to 1.0 or 1.01 stock rom, it will active even when I use the latest Ad 3.0 honey OS in my SD !!
Let me know if you have any clue on this please ~
Turn off the screen and wipe it for fingerprints and it should work normally. This has been a well documented flaw from the capacitive screen's design. The 1.1 update has seemed to help but it still happens occasionally.
Thank you man.
Do you mean this is just because of fingerprint??????
Not entirely from the fingerprints, what I believe is happening is when you long press on the screen the device starts thinking that its multiple touches in the same area and will temporarily remember those touches and tries to keep up with you by these so called phantom touches. It happens a lot to me when I would play a game where you constantly were touching the screen and it then would eventually start to go crazy. I could then recreate it every time doing this and turning off the screen and doing a wipe for fingerprints would correct the problem.

I also experienced the same issue early on. It happened when my NC was plugged in. I unplugged and the problem immediately disappeared....never to return.
Good luck.
I had a really bad phantom touch problem, focusing on the wifi/quick options menu in the stock eclair rom. Ever since I flashed my emmc with the custom nookie froyo rom, the phantom touches have completely gone away. I wish I knew personaly what could have changed in order to get that result, but I'll take it.

[Q] Just a broken screen, or more?

Good evening everyone!
Little did I know, my father had his OG Droid just sitting in a drawer when he upgraded to the Inc2. I had him ship it out to me this past day so I can use it as my play thing!
Upon first boot up, before root or anything at all, I noticed the left side of the screen wasn't responding. Say, the back button and all the way up. Everything beyond the back button seemed ok.
I felt that maybe it was just a quirk with how old and how much he had used his phone, and was hoping for a software fix (read - flashing) and not a broken screen or any hardware problem.
As I began wiping data and resetting everything that could / should be, it started to get worse. Random "touches" on the screen, menu keys moving, total unresponsiveness. Just general whacked out problems that make you want to throw any device across the room.
I did manage to get Clockwork on, flash into recovery and install (successfully!) a plain 2.3.5 ROM I like. It was annoying with all the menus and key presses going all over the place, but they weren't happening while in recovery, so I was hopeful.
Upon the successful bootup of 2.3.5 though, the screen was even worse - more bouncing around, less responsive, etc etc.
So, my long winded question: anyone have any idea if this could be any problem but some sort of screen mishap or other hardware problem? I kind of hope it's not, just so I can have a device to constantly play with.
Thanks in advance!

[Q] Frozen Screen

First I want to thank all the people on here who have help me out many, many times and never knew it. That's why this is my first post but unfortunately I can't find an answer this time.
I have a AT&T GS4 Active that up until yesterday was rooted since new with no issues. About 3 months ago I noticed a yellowish half moon halo on the left side of the screen halfway up that does not show up on screenshots. Then two days ago I was dialing a number and the screen just froze and would not respond to any touch. I pushed the power button to black out the screen and then again to turn the screen on and it worked fine for a little while but got progressively worse throughout the day to the point where it was unusable.
I than un rooted it and that did nothing so I re booted the phone to factory and attempted to do the OTA update many times, it would download and then reboot and at 25% it would stop and not load the update. Since the factory reset the screen has frozen twice so I can only assume it is going to get worse again. I don't know if the "yellow halo" means this is a hardware issue or not. I am willing to SS and install a ROM if anybody thinks this will help.
Any suggestions would be very appreciated.

It sounds like a hardware issue, but you could always try flashing the ML2 Odin files to see if it fixes anything. Make sure you do not flash the ML2 bootloader or you will be stuck on ML2 with no way to downgrade.

Split Screen Mode Gone Crazy

Hey all. Just grabbed a new 32 gig Edge on Thursday. Everything was working fine up until this morning. As I was scrolling through an article, the Split Screen kept coming up and going away. I thought I hit something so I paid it no mind. As time passed, it started going crazy on its own. I wasn't pressing anything, just unlocking the phone and putting it down on the table.
It was almost like there was a ghost (or remote operator) screwing with me.
I did a factory reset, thinking maybe one of the apps I installed was causing some kind of issue. Still having the same problem.
Anyone else dealing with this on their new phone?
Hi,
I've got the exact same problem with my 32GB Edge. While my kids were playing some Lego Junior game on it (yeah I know, that was the the last time ), it started going haywire. It's like someone's pressing the button for recent apps all the time and sometimes very rapidly.
After a factory reset, logging on with my own Google account resulted in the same behaviour. So I tried another factory reset and tried my wife's Google account while restoring as little as possible. Now things seemed a little better so I tried the same with my Google account. That went fairly well (it now pressed Recent Apps once only when I pressed the Back button myself) but after a little time of fast charging, it went all crazy again.
So maybe it's got something to do with (over)heating? I'll try to leave it off now and see what will happen when it's cooled down.
Did you (or Samsung) happen to solve the problem?

sorry! didn't realize there was a response here. i've yet to find a fix. it'll happen every now and again. i try to reboot it, but sometimes i can't because of it going crazy. once rebooted, it behaves for a little while.
but in terms of the back button giving me recent apps, that happens way too often.
I've had the same problem with the S6 edge 64G. After Samsung advised on a factory reset, to no avail, I spoke with my network provider who suggested a replacement sim. This worked for a few days but then back to the exact same problem as described above. Working along the lines of the sim replacement I noticed this problem occurs more frequently in areas of poorer coverage. I tried the phone in Airplane mode when I noticed the problem was occuring and it stopped straight away. Haven't spoken to my network provider since but now I'm not sure if it's a sim issue or the over heating problem.
Its hardly an effective fix having a phone that you can't make calls on so I might have to settle for the' return to samsung for repair' option.
Hope this helps a little in finding a solution
Does anyone have a fix for this. My phone started doing this whilst on charge, and I have a gorilla case, so the overheating thing made sense until I let it cool down and removed the case and it still happens. The reboot (holding all four buttons down) does not work.
Multi-screen glitch
I am having the same issue on my Galaxy s6. I installed the Multi-Window Toggle app from a developer on this site and now instead of switching in between recent apps and multi-screen, it switches between recent apps and the home screen. It doesn't seem to be related to overheating with my phone. It can be just sitting on the counter and start doing it all on its own. Very disappointed.
I'm having the same problem with my s7 edge 32gb. Haven't found a fix. If ywguys upgrade to an s7 you may find the same issue unfortunately. Its probably a software problem. Hopefully a system upgrade can fix it soon.
Hi, I have a Verizon Galaxy s6 and got the software update late last week. Since then, my split screen has gone crazy. It goes through these cycles of splitting the screen and vibrating. It is unusable when in the cycle. HELP!!!
Hi, I too started having the same issue with Galaxy S6 on ATT. Any fix for this?
I got caught in a monsoon the other day (really heavy rain) I was only in it for maybe a min and a half till I could ride my bike to cover, but unfortunately, I was soaked and so was my phone. I wiped the water off, but I noticed that some may have gone in my headphone jack because everytime I pressed my back button the multi window button would light up and then start flickering and turn off. So I turned my phone off for awhile to let it dry out and now my button is not working at all. it's been 2 days of not working and all the sudden tonight it starts opening up my recently used apps and telling me it's going into split screen mode and glitching like this 20 times or so, every couple of minutes. My S6 has gone downhill the past couple months. 3 weeks ago it stopped charging completely the battery would drain after 2 hours of regular, to minimal use and when I went to go plug it in, it would notice that I would plug a cord into it, but wouldn't charge. It did that on and off for a week. now it charges, but tells me it's over heating every couple hours. Now it's doing this glitch with the button. Kris upfront up either split screen, or recently used apps overt and over again. The button still doesn't work, won't light up, or do anything when I press it. It'll only lights up when the back button is pressed. I just thought my button was broken cause of water damage, but maybe it's a software issue?
I replaced my screen protector. Problem resolved!
Replacing or removing screen protector didn't solved my problem. I have edge 6 32gb and it's clearly not an software issue because I have flashed my phone with different firmware with odin and still the problem occurs again ....
I'm thinking this might be due to screen protector I recently installed. I had the thin one before but since adding the thicker one this has started happening. So much that the phone is almost unusable. If this doesn't work, the phone might be going out the window!
Samsung Galaxy S6 Split Screen & Apps Gone Crazy
I also have the split screen issue with my Samsung Galaxy S6 (not an Edge). I've done everything recommended up to and including a factory reset to no avail. I also removed the screen saver (which was relatively new) and that did nothing.
I also have an issue with the recent apps toggle key, which in the end, may be the real issue. The key only works randomly and lights up even less than that.
Anyone?? Any other ideas? I, personally, have reported this to the BBB and requested an inquiry since this has been a known, major issue since long before I purchased the phone in September 2015. We are in the middle of the inquiry now. Will advise as to the outcome.
This works!!!!
I have a fix but im new it wont ket me post till after ten post. Want help email me..bummer just trying to help.

I had the same problem. I thought it was because glass was cracked. Tried replacing the glass, and actually ended up getting an entire new AMOLED/digitizer assembly, installed it, and it has the same problem. So annoying! I can't even send texts because it splits the screen and/or opens recent apps like every 0.5 seconds. The only thing that helps is having one finger continually pressing down on the screen as the app is open, which will let me scroll with my other finger and the app wont go in to split screen. I think it is a software/internal hardware problem. Not Cool, since this is an expensive phone.

I took the screen protector off of my wife's s6. It was okay for a few minutes, then it started again. the same thing everyone else is experiencing. 'Can't afford a new device right now. So she has to downgrade to a s5
This fixed mine
Hi guys my sister had the same problem and I tried the toggle app and that didn't work for me but I found this vidio on YouTube on how to disable the multi window button and it worked for her! I'm not allowed to send a link but if you type into YouTube 'disable back and multitask button' it's the first one to come up. hope this works!
My samsung s6 edge has been switching between recently used apps, going into switch screen mode and both power and home buttons haven't been working consistently. If I do a force restart the buttons only work for 10 mins or so. I also did a factory reset and am currently using a replacement phone because the reset did nothing. Some people seem to think this is due to an SD card corruption, I'm not so sure. My screen is also shattered but it had been shatter 6 months prior to this problem occurring so it is not related. If I take the phone in they'd have to repair the screen as well and that will cost too much for me.
Hi, I have had this issue twice and both times I think it was moisture/humidty related. The first time it resolved itself after presumably drying out any condensation. Today I had the same issue and fixed it by blowing a warm hair dryer into the bottom of the phone for a few minutes.

Random black screen issues?

Hey guys, I've been having some issues with my RP2 since fresh out of the box. Randomly, my phone screen will not turn on and will stay black. The phone itself isn't shutting down, as when I attempt to turn on the screen, I can feel the haptic feedback from an attempt to unlock via fingerprint.
It's really touch and go, sometimes its good for a day or two, sometimes it'll do this two or three times a day. A hard reset (Pwr+Vol Up) gets it back running again, but it's getting really annoying and interfering heavily with just everyday use.
Anyone else having the same issue? Anything I've read around the web hasn't helped or isn't pertinent. This happens on complete stock and running Arter97's kernel, so I'm left to believe it's a hardware issue (please no) or a ROM issue, i.e. Razer did a crap job.
Any thoughts? Thank you in advance!
