Back button Ghosting/pressing itself

Hi, I have a galaxy s6 and its back button is pressing itself, without me touching it, closing apps and making it unusable. Using warranty isnt an option as it was bought abroad.
What are my options? Is this necessarily a hardware problem or could it be software related?

me too have this problem

I had similar then found that the animations (in developer) were set to 0.25, reset them to 1, used rebooted a few times and now its OK. Could be coincidence but tried reboot, clearing cache etc before the Animation setting?? Weird but may be worth trying.

my phone is already set to animation 1s
I change launcher and now the problem seems to be less frequent (I install nova at the place of next launcher)
I think that the problem maybe depend by some app not perfectly compatible with lollipop 5.1.1.

I had this problem on my S6 and when I googled it, it seemed to be a recurring issue on Samsung phones. Poor insulation causes the radio to leak into and trigger the captive buttons in weak signal areas. What eventually fixed it for me was replacing my tempered glass screen protector with another one, as non-unrelated as it sounds.

Mine never made that, even in poor/nonexistent areas... I believe that has massively to do with the production quality of every particular product. Some of them might be a little bit better fabricated than others.

I had this problem. Luckily I was on warranty and just switched it out. I would try factory reset tbh, that's the only thing I didn't try

Screen Flickering

Whenever I decrease my phone's brightness to the lowest, i can see some flickering below my phone's display. Does anyone here experience the same issue/ have a fix for this?

j7 flicker at low brightness
Whenever i face low the brightness of my j7 below 15% it started to flicker...
Please help and tell is it problem with the software or hardware.
I tried safemood but it still flicker
I also tried factory reset but still flicker
What should i do now?

I am having flickering problem in my j7,
When i am doing completely brightness low then it starting flickering... I have done data reset.. Wipe data reset but it's not work.. Please help me...
My Gmail is.... [email protected]

Its happend because of you pluggrd your phone with other chargers (volatage variation), once its happen can't do anything have to change full display. if your phone under warranty then goto near samsung care
Warranty is over and still you dont want to change display ?? Then slightly increase the brightness till the flickering is over and use bluelight filter app.

My j7 have problem.Is there a solution to this problem.

I also have this issue on my j7... sometimes. It doesn't seem to be a constant issue for me, just occasionally. I currently have it at the lowest brightness with no problem. Another symptom of this bug is a flash of pink when I lock the device.

I was also facing the similar issue and my phone is under warranty. I went to Service Center and told them that the issue keeps happening after New version update. They said it's a defect in my display in Samsung J7 and they agreed that they will replace display with free of cost since my phone is under warranty. Thanks to Samsung.

I am also having the same issue in my Samsung j7 phone.i am using ooriginal samsung charger.then how do I get this problem .plz help regarding this issue. I bought this 8months back only. Can I go Samsung care

Kwa nn mwanga wa cm yangu samsung j7 unacheza cheza chini ya kioo

uow
yes dude

My one is also. I updated to Android 6(Officially ask) Then After 2 weeks Its came to picture. I feel its come with update otherwise no volatage damaged. Why because I used original one only. And use with very carefully.

I have also same problem please tell me some solution for it

I have also this problem. how to fix it guys?

Try downgrading to lolipop
Ps:Not tested by me just heard this

Yes me 2

Same problem!!!!Please someone help

Whenever I decrease my phone's brightness to the lowest, i can see some flickering below my phone's display. Does anyone here experience the same issue/ have a fix for this?

Go to customer care
There is no way you could fix this.. It is a hardware problem. They dont check if you tripped knox or something, at least in my case they didn't. Because it is a hardware problem.

And also who thinks it is their fault, it's not. It is samsung's fault. Whole j7 series has faulty display like note 7 battery.

[Q] Backlight/screen flicker at low levels?

Hello, I'm just getting my replaced K1 from Nvidia today and I'm incredibly disappointed to find that this unit is showing the exact same symptom as the one that I originally sent back to them; the screen flickers at low backlight levels. It doesn't matter whether I have PRISM set on or off or adaptive brightness, the screen flickers.
To me a screen that flickers like this is really not acceptable.
Does your screen flicker when the backlight level is set low? Should I keep trying through the RMA process with Nvidia until I get one that works? Or, am I just going to keep being disappointed?

Disabling quto adjust solved it for me

On 0% brightness the screen sometimes flickers slightly mostly perceivable on snow white backgrounds like the Settings. Bump the brightness up a notch like 2% and the flickering immediately ceases. Deactivating PRISM can help in some cases too.

Nvidia customer support has told me that they've isolated the flickering problem as a software issue and that they will be issuing a fix for it in an upcoming update. Hopefully this is the case.
I am returning this previous RMA replacement K1 again due to the fact that it came with a mark on the screen, so hopefully when I get the new one a fix for the original issue will be forthcoming.

Here me too ... and this is the third K1 replaced (I changed the old k1 for other problems)
edit: i found that video on YT https://www.youtube.com/watch?v=h24YdpHinVE

Yes. it happened since i upgraded my tablet to Shield firmware version 5.0. upgrading to 5.1 also cannot resolve it. It never happened with previous firmware versions.

it must be a software issue since it never happened before the firmware version 5.0. I noticed it started to happen when i upgrade it to the Shield firmware 5.0 (it is even worse at 5.0). then, when they release 5.1, i noticed that the flickering is still there but a bit better than previously happened in version 5.0

I doubt that. I'm still on Lollipop 5.1.1 and the flicker exist inconsistently.
I presume that the screen merely doesn't get *enough* juice at 0% brightness hence the flickering. A software update would consist of bumping the brightness level of 0% by 1 or 2 percent. Problem solved.

Yes, it looks like a software problem, because on my current K1 i never have that problem. After a seriously freeze ( impossible to reboot manually, after several seconds it has restarted by itself) the K1 shows a burn-in image for some seconds (like the amoled) and then it began to flicker too much, now it's much better, but there is yet.
this is my video: https://drive.google.com/file/d/0B_0vaad8L7zDSGtzaW1BN3RlWU0/view?usp=drivesdk
But i don't think is a problem of the update, I agree with what @Niii4 said, maybe the system can't support the lowest brightness,
maybe is an hardware+software problem

Display & Touchscreen Issues

I've owned an unlocked U11 (US) since launch day, and it's been performing flawlessly until these party couple of weeks.
I started to notice that on occasion, visible scan lines would appear on the display.
As well, touch response would suddenly drop or get really jittery. This causes a lot keyboard typos (i swipe) and accidental instagram likes (due to the jitters!).
The two issues do not always happen at the same time.
I ran that line drawing diagnostic test, and it does appear to fail every so often.
I've babied this phone since day one, so it's really frustrating that this is happening.
I'm wondering if anyone else is experiencing the same issues. Could it be software-related?

Yes. I believe HTC needs to do a update.

Yes, you are getting the same problems? Or yes, it's software?

I also noticed this behavior. In earlier Firmwares I had this way more often than in the actual one, but this scanlines appear from time to time. Seldom but they appear. Contacted HTC already, they believe in an software issue. Let's look what the time brings.
I think you can force them if device sleeps and you cover the screen completely with your hand. If the device wakes up the scanlines are noticeable.

the scanline thing happens with all of them, its not a bug specific to your device, sadly its so hard to pint point and report

No it doesn't happen to all of them, I've never seen this issue once. The scanlines anyway. The touch screen is overly sensitive so if I don't move my thumbs away as I type, it acts like I'm still on it. It's not in glove mode either, that would probably be unusable.

Looks like I'm not the only one with touch screen problems:

Guys can you do the screen line test and see if hitting two sides of the screen in succession as if you're typing a message joins up and draws a straight line?

It does. Totally repeatable when the taps are super close to being at the same time.

Turns out it's normal - my brothers one plus 3 does the same.
I cleared my cache partition and went back to using the original HTC keyboard to see if it helps. It does seem a bit more behaved at the moment.

Well its definitely doing it with SwiftKey. I've been getting really aggravated because it will delete words as I type, close the keyboard occasionally... SwiftKey has a gesture to delete words and sentences and guess what that gesture is? A line on the screen.

Hmm, I get what you're saying. But my brothers One Plus 3 behaves exactly in the same manner but doesn't have the weird jitters.
I'm thinking it's an Android thing to join the two touches on a software level, however if the digitiser is recording a straight line touch end to end that's a different matter.
Here's another idea, enable the pointer location in the Dev settings and see if you get a straight line with that when touching in succession - I don't, and hence that's led me to think joining the two touches on a software level is intended.

Its not intentional, they will undoubtedly fix it at some point. They had to fix it on the Evo 4G too but it was not as bad as this...

Just updated to 1.27. Previously in 1.13, tested tapping using sketch app, there were 4 horizontal lines produced during 50+ taps. Now it's 0.
6hours in, I feel typing is better now.

I remember the same thing when HTC 10 was released and I had the same issue with over sensitive screen. After couple of initial updates everything was fixed so like someone already noticed with 1.27 base HTC is refining this speed deamon and they already addressed this problem

That's very interesting. I wonder why my brother's one plus 3 behaves in the same way, but doesn't cause any adverse effects...ah well there's hope. Thanks for the update.

Swiftkey is amazing because of those 2 gestures but I've had lots of problems with them on the U11, especially when the keyboard is closed and I end up pressing random buttons that were behind the keyboad. It's a really bad and dangerous issue. The only fix before 1.27 is to just disable the gestures.

Is the typing still OK? And can anyone else on 1.27 confirm if the fix is good? Thanks

Used to make ghost swipes here and there when using SwiftKey. Now it's not happening anymore. Not even once since 1.27

Honor 9 - issues that make the phone worse

Hello I have my honor 9 since it launch june 2017.
I use global rom strait from the (aliexpress) store. I use EMUI 8.0.0.368 (C432) my model is STF-L09, Kernel version is 4.4.23)
Slowly i get frustrated from the device and ill explain why (if there are solved problem ill like to hear that)
1. Performance issues - after every update or upgrade it become slower and laggy, and now it reacts even slower than my xiaomi mi4 !
2. Reliability - since now screen got broke (too easy), battery got damaged (bulged) and the rear cover opened, and now camera getting out of focus (well known huawei problem that on youtube you can find temporary solution - hit hard :crying . good point for the phone is that fixing isn't expensive.
3. Camera Video issues - focus was never good (before my recent problem) and stability bad for 2018 phones.
4. Heating too fast - in summer phone get hot and screen become darker so almost cant see anything.
5. Display - till today it can not be automatic brightness cause it getting immediately to minimum light - come on couldn't they fix it till now ? another issue is not bright enough in direct sunlight no matter what other users say, compare it to samsung phones and you understand !
6. Connectivity - Wifi too slow. i test the wifi speed of the phone next to others and next to laptop and it was half speed of the others
7. Smart assistance - Draw never work at my phone, no matter how hard i knock on it
Please if any of the issues solved il like to hear that
Thanks

I never had one of these problems and I am on 8.0.0.368 too.
Well, after a time in full summer sun and full usuage it got a bit hot but i guess that is normal with every phone.
Maybe you should clear all caches, there could be some rubbish left from previous firmwares.

A. I already replace the battery a month ago so its a new one. i know no warranty anymore (no worry)
B. Can i test light captor or replace it ?
C. regarding Smart assistance any thoughts ?

I've had mine for 3 months now and haven't seen any of those problems . sounds to me like the phones been damaged , probably dropped on a hard surface .

i checked my light sensor and it work fine, the problem must be software !

Try a full factory's settings restore.

factory's settings should go to Chinese version or global rom ?

A factory reset won't rebrand your device.

No i didnt do nothing. it come like this from the shop (aliexpress to shop) when i asked them to send it with global rom
Why its not look ok ?

I said you may have rebranded wrong because your old post : https://forum.xda-developers.com/showpost.php?&p=73073528
But if it was done last year by chinese seller you should be ok.
So when you get your phone you were on nougat C432, since then, you're now on oreo.
Maybe somethings gone wrong during the last year updates. Does your flahlight still working ?
It may be a good thing to test again your problem after
-a reset to factory settings
or better
-a full restore with a dload firmware image via sdcard or usb-otg

I did not do it it come from the shop (aliexpress top shop) i requested global rom

Update - after factory reset i test sensors and all working fine and also flashlight (164,000 on antutu), but still some issues:
1, autobrightness still bad - in very direct sun light reach only to half so cant use it .
2, Smart assistance - draw still not working no matter how hard i knock
