Develop Bugs

The DOA thread (did your 2nd(or more) device improved)?

Ok, so I returned my phone still in DOA period.
My problems were the glitching all over the place, and not just once a day, but it kept on getting worse, youtube, camera, browser, status bar, apps, multitasking, scrolling, keyboard, jumping white line in messages,etc...
Mine also was creaking arround the front camera and part of the corner of the screen there too.
My battery was displayed wrong all the time, so I couldn't see the right %.
Yellow bottom of on the screen.
Games were lagy, Tegra 3 and normal like teeter.
1 dead pixel.
Probably forgetting some problems now.
Somethings will be software, but because I(and most of us) don't know what is software I preffered to send it back before the doa period was over. Also some posters stated htv told them to send it back, witch problems same as mine.
Also if this is software for most of the part, than why isn't everybody getting the problems.
So I made this topic so you can tell what the problem was with your first device, and if you allready had your second (or third, etc) and what improved and what stayed the same... So you can we get a better vision on that.

My first phone arrived yesterday and is getting swapped out by a currier tomorrow for what will then be my second device.
The problems I am having is the jumping/bumping at the bottom of the screen; this is very inconsistant but does happen more often than it doesn't. For instance I was using the phone for 40 mins earlier it was happening, then for 10 mins it wasn't, again it happened for 5/6 mins and then didn't happen for around an hour but again its happening as we speak.
I've also had the problem whereby you can't unlock the device by pulling up the ring, and I have to shut down and startup the phone for this to be fixed. This has only happened twice so far; but again should not happen at all.
Lastly I have had the problem that when you lock the device the screen turns back on, even when you only pressed the lock button once.
I think thats everything... I do believe its software problems more than hardware, however as you have said why isn't this happening to everyone if that's the case. I guess you could look at it that maybe it is but they are either living with it or reporting it direct to where they purchased it from; either way they are not posting it on here. Who knows?
Now I do understand bugs are there in just about every phone and to be honest they are normally bugs you can live with until an update; the problem here is that the bugs are completely preventing the use of the device and/or making the use of the device very difficult. No phone should be released with this being the case.
One thing I do know for sure is that its happening to those who got the phone from a network (mines from Vodafone) and those who got it SIM free; in all areas or the world. This means they (Vodafone, Orange, O2 etc...) have not caused these problems so it eliminates any tweaks/software they may have placed onto the device meaning the problems do entirely lie with HTC to resolve. Lets just hope they do; or more importantly lets just hope its a small number of phones that are affected and that our replacements are okay.
I will let you know tomorrow what the second one is like... (sorry for the long post),

How did u notice a dead pixel
Sent From My HTC sensation (desire with rcmix s )

Phone turning back on after i pressed power button to lock the screen, got that too. But happens at random, so not always.
I saw a very tiny shiny spot when in a complete dark room, on a black background. Dead pixel i suppose.

Im considering getting it online but not sure what to do if i get a dead pixel
Sent From My HTC sensation (desire with rcmix s )

Send mine back because one of the 2 yellow spots didn't go away after 10hrs screen on (5 days) and I had some random restarts.
I don't want a faulty device, some devices will keep giving problems while others have no issues from the start.

You would be able to send it back if you bought it online, just like buying it from a shop. They have to give you the same period of support...

Please help! Galaxy Tab S glitch.

So, I got a Tab S a couple of months ago and then about a month ago I started having some trouble with it. Lines flashing down the screen and the screen turning off. I'd have to lock and unlock to get the screen back on. Sent it to Samsung for repair and they sent it back about two weeks ago saying they couldn't find a problem. Well, the problem is definitely still there so today I took a video. Samsung said I would have to send it back in for more tests and that they would not watch the video. I'm afraid they're not going to find anything again so I was wondering if anyone had a similar problem and could help.
Samsung Galaxy Tab S 8.4 glitch: https:// youtu.be/ 7kOFewYbNzw
That's the video, remove the spaces

Does it still happen when you use power saver mode?
When the display goes blank, you press the power button twice, once to enter sleep mode, and again to wake it up, so it looks like a loose display connection or a faulty display, does the screen ever come back on without pressing the power button.
Does the brightness level effect how often the display goes blank?
John.

Thanks for getting back to me. It does still happen on power saving as it turned that on not long after I took the video. Screen brightness I'm not sure though because I packaged it back up to return or send for repair, whichever I decide is best to do.

This happend to me 2 times in the 6 months I have the tab s, seems more like a software thing for me.

All you can do is a factory reset, then install no apps (in case they cause the fault) and see if the problem is still there, if it is, all you can do if you are still in warranty is get an replacement or repair.
John.

I've got the tablet back out of the box while I wait for my repair packaging. I did a factory reset when I got in from work and restored a backup and straight away I had to the same problem. I've now done another reset but with out restore, I haven't even logged in to my Google account. So I'm thinking it's either an app I have installed, not that there were that many or some of the factory installed apps I disabled/removed. I don't think the restore from backup reinstalled apks such as remote play and show box so they can't have been the problem. Could deleting any of the factory apps cause any problems?

You can only delete factory apps when you are rooted, any you have delete without root will make no difference to your tablet stability, try and use the stock apps and see if the error shows.
John.

I've disabled a couple of them like New York times and the office suite one. It's working faultlessly at the minute. The problem is when it came back from Samsung it was working fine for about a week and then the problem returned so I can't be sure if I've solved anything or its just a ticking time bomb.

I don't know how Samsung tests the tablets, they will just send it back if they cannot find a fault, download a couple of benchmark apps, to stress your tablet and see if the fault shows up, see if increasing the brightness while benchmarking doe anything.

Just ran Geekbench 3 adjusting brightness from lowest to full and nothing, worked fine. I'm at a loss, I know that if I send it back to Samsung they're not going to find anything and spoke to Very today, they won't refund me without Samsung authorising it.

Is that Very UK, if so they send phones and tablets for repair, if they cannot repair your phone/tablet in 30 days they give you a refund unless as you said the manufacture says to refund.
Hopefully your problem will not show again, but it could have been an downloaded app, or an update to an stock app that causes the problem only time will tell.
I suppose you are on lollipop, I decided to stay on Kitkat as it`s super stable for me.

Yeh it is, but I bought it a couple of months ago. And they've have to find the fault first.

Hello i have similiar kind of problem i mean it shows stripes and boom reboot or sometimes screen goes black.I wonder if you found any solution?

Have you done a factory data reset from the settings menu, you will loose all internal user information so backup first.
If you have done an reset and still have the problem and you are on the stock rom and have not flashed an rom and have not rooted then you have an hardware fault.

Yss i did it 2 times didnt worked.Weird thing is when i open powersave mod its not happening maybe i should use powersave mod always meh

If you are out of warranty check the battery as it sound like an bad connection or a bad battery, there are guides on youtube on how to get the cover off the tablet, you can buy a kit from the link below for $65 or cheaper on ebay for the battery and pry tool.

It is a screen burn ,i have tried to solve problem with Screen Burn-in Tool app from Play Store
but no success,this problem have also few my friends with lg g4,i newer buy any lg phone again, lg is better to produce tv sets and wasmachines because as phone manufactures sucks.

Same issue here too, it isn't necessarily burn in, more image retention I guess which tends to happen to some LCD's, tried all sorts of things to fix it, if anyone knows how to fix this that would be awesome
Guess we'll have to either get the device replaced or replace the LCD

If it's retention the LCD won't have to be replaced. Just wait a little, and it's gone.

And it inst always there, it knows to disaper.
And one more thing, it constantly changin, for example now i see 12:30, and for 2 minutes i will see 12:32, not one picture burned in.
Sorry for my English, i hop you will understand what i trying to say.

Its pretty bad retention if thats the case, not permanent...only really see it on grayish backgrounds....Ive left the phone off for days...switched it back on and within a matter of minutes my status bar is burned in lol

Same problem here pink burn that appears only on gray with a few minutes of use.
I was wondering if its just my device or not.
And now that i know that is the case i guess switching the phone display will not solve it.

I am getting this issue as well. Pinkish tint (when there is a light grey background) and image retention on the top of the screen and I can see those little icons. Did you get the problem after motherboard replacement due to bootloop issue? I am regretting my decision in purchasing LG G4.. :crying:

It is the display, friend of mine replaced his and he no longer had this issue.
I think he ordered a $70 USD replacement off Amazon and did it himself since LG requested for him to send the phone to Taiwan.

To be honest it does not really bother me,the only thing is that i can not put a gray wallpaper :/.
And when you mention this i think it actually started only after i got my motherboard replaced because of the bootloop but i might just did not notice until than..
And no regreting is needed alot of people that i know with s6 are not so happy about it..and the only other option was m9...so.....if you like me and had no choice the g4 was the smartest choice lol and i am quite happy with it...

Well i was talking about that, if you would give your phone to lg they will replace with the same display..so i dont see the point...
And the replacement displays you cant tell how are they as in brightness battery drain and color accuracy...
I guess if it will get worse than i will probably replace it..for now its fine enough lol

Meh...it's really not a huge problem lol, it grew on me after some time and it doesn't bother me anymore
Hasn't gotten worse over the past 6-ish months or so, so I guess it'll stay this way
I'm from Jamaica so sending it to Taiwan is going to be a bit of a problem
But as for the replacement part, I definitely get what you're saying, I asked my friend about his for the purpose of this thread and he told me that the battery life is the same, brightness/quality is similar to the original display, worse case scenario if you need to change the screen I'd say go for it.

I have found a some kind temporary workaround ( i don't know is that correct language expression in english so sorry for that )
Mainly here is what I did : I have flash latest SUPERXE kernel for stock rom android 6.0 from here , after flash from Play Store I have installed app Kernel Adiutor ,from the drop-down menu selected Screen section and aply this settings :
RED=230
GREEN=235
BLUE=235
Minimum RGB Value=35
Saturation Intensity= 30
Screen Hue=0
Screen Value= 125
Screen Contrast=127
After this no more red colored retention on gray background,not even in TWRP recovery.
This solution is only for rooted devices with unlocked bootloader,I hope this will help You
After kernel installation i have run few times antutu benchmark,so maybe this is also have influence on screen refresh.

This worked for me, too Thanks for sharing.
Anyway I will try warranty soon.

Dear guys, 12/2015 I have same issue that burning, my local warranty service ok change a new LCD, it is very OK after replacement, no burn any more. But after 6 months the same issue come back, it is hardware issue. LG always have issue about hardware in flagship more than other competitor.

Not a G4 owner but I have used a G4 before as well as a V10 and a G5, currently own the V10. This issue is present on all three devices and isn't a question of if it will happen, it's a matter of when it will happen. I noticed this issue with my display a few months ago and the entire affected area has a weird yellowish hue to it which is most noticeable on a lighter grey hue and as of now have grown used to it to a degree: still annoys me a bit. Also had a friend whom I recommended the G4 to and he had this issue with retention since he got it though he barely notices it since his phone is almost always set at 0% brightness
Anyways, at this point the main cause for this as I've said in a couple of threads is the display technology itself. I'm guessing this is one of the side effects Quantum Display has for offering near-amoled quality with vivid colors and blacks in comparison to regular LCD panels. Basically, even replacing the display is a temporary issue and still a lottery as you may get one with no issues until a year later or one that already has retention out of the box.
At this point, I might even tolerate amoled displays or non-Quantum Display lcd panels but it's too bad LG makes great phones. Oh well, just another thing to keep in mind when getting a phone from LG

I started getting this burn in and i am 95% sure that it didn't happen before. My G4 was in bootloop so i sent it back and i think that they replaced motherboard. After about 2 months of usage i started noticing this and as i said i am 95% sure that it didn't happen before motherboard was replaced, only if i didn't realise that but i am sure there was not this problem. :/ :/ :/ Is it actually possible that it is coz of motherboard replacement and that it can't be fixed even if i replace screen?!?!

It's not a motherboard issue but a display issue. With the G4, V10, and G5, there will be displays that will have retention out of the box or in a matter of a few months and then those who don't get it until 2 years into use or in fact, never at all. Only solution is replacing the display but that's a bit of a lottery in it of itself as you don't know if it won't have its own issues and I'd imagine constantly buying new LCD digitizers to grow costly that you might as well just buy a new phone altogether.

Bluelight Filter
Try " Bluelight Filter " app from Google store , I had the same problem until I used the app .

Screen retention fix supposedly on the way

I chatted with a oneplus agent. Long story shot I asked if the retention issue was software or hardware. According to this agent she spoke with the technical team and they're working on a software fix so according to OnePlus it is indeed a software issue. Figured I'd throw this out there for anyone plagued with the same issue. I didn't ask about the black bar cause I only see it below 15 percent brightness and I never have the screen that low.

OP agents don't know what they're talking about. Different agents say different things, and of course they're going to deny that it's a hardware fault because then they'd lose money.

Can you elaborate what you mean?

To further explain a lot of people have been suffering with the image retention/ghosting issue as well as the black bar in the status bar. I asked a OnePlus agent if this issue was hardware or software and supposedly according to OnePlus it's software and should be fixed in the next ota. I'm hoping this is true but like the guy above you said they could be just saying that to stop people from sending their phones back for replacement/refund or repair. If this issue isn't fixed in the next ota I'm sending it in for rma to either be replaced or fixed. Either or doesn't matter to me as long as I get a fully functional display without defects.

Mine is no where near that bad. Mine is only the status bar that has image retention but I never really notice it unless I switch to a gray background and look for it and even then I can go to a white background turn up the brightness and then back to the gray with normal brightness and the retention is already gone. Even if they don't fix it with software I'll probably just keep it cause I seem to have a relatively issue free display other than the retention with the status bar icons.

So just adding an update to this post. 10.5.10 did not fix the screen retention on my OnePlus 8 pro. I ended up starting a repair rma and shipped it out with the UPS label they sent me. Hopefully they replace the screen with a non faulty one.

don't get your hopes up mine had a build date of May 28th for the new RMA 8 pro even with the new update it still has image retention

Wow that's ridiculous. I think it's time they actually address the problem of faulty displays rather than trying to mask it.

I believe its definitely screen retention issue and not burn in. I am not sure if its HW or SW issue but i made an experiment. In which i checked what icons i can see in status bar and then i changed them and i could no longer see the ones that were previously there and only the new ones. This makes me believe its a SW issue rather then HW issue.

Yes, that's perfectly calls temporary screen burn in.
It on amoles since ages.
No fix for it.
You use black theme, you don't get screen retention issue.
If you use white theme, you get it.
White color with high brightness caused this.
And it's temporary.
It's goes out if you keep screen off for specific time or change theme to black.
For me, most of issue happens on in call screen where we put call on hold etc.
There I can clearly see shades of navigation bar buttons and nav bar layout.
Also, there are few black lines / color distortion happening on lower half screen in call screen.
But it's happen only on that occasion, so I am fine with this.
Also, there is too much black crush issue when brightness at 40 % only. Not on lower, not on upper.
So, i am fine with this.
Customer clear said that it's hardware issue and I need replace screen.
But I m not going to do that because I fear I will get more bad screen than this.
I don't have any tint issue at all.
.
.
.
And, it's hardware issue, no software can fix it.
Our android already includes screen burn in protection ( slightly change position of icons pixel by pixel on status bar and nav bar)
So, it will remain same.
We all are got 3rd grade amoled panels from Samsung.
And oneplus can't do anything about it. ( they can't afford it)
For proper fix, they need to recall all devices and change panels from different vendor which is too costly and time consuming.
Also, soon there will be 8T pro. So everyone going to forget this device and it's issue.
I previously had 7T and it was having green tint issue on lowest brightness, 8 pro cause retention issue.
So, this is my last device of oneplus.
You can't get good hardware, good software and low price.
Take it or leave it.

I know what you mean it's similar to burn in, id say the only way this should be considered a software issue is if the screens integral settings are pushed too high, if they're within the boundary of what's acceptable then it'll be hardware.
Personally I haven't had this issue which suggests to me that not all screens are or have been created equal, which to some degree is to be expected, even Apple has issues with their screens, as do Samsung and Sony.
Something you could try would be to alter the RGB output of your display and live with it for a while and see if it helps, essentially lower values.
If the problem is voltage/ amperage to the screen then without some tinkering you'd have to wait for a fix, I would assume they're aware of it.
Time will tell I guess.

Severe brightness issue (screen largely unusable)

Hi all, I have a problem with my stock T-Mobile US S9. A few months ago this weird thing happened where if I turned on my screen immediately after it turned itself off, only the top few lines would be visible. The whole screen would take input, but you could only see a little below the status bar, maybe. If I waited a bit and then turned the screen on, it would work normally, with the whole screen visible and looking fine.
It's gotten progressively worse to the point where this happens most of the time I turn the screen on. However, I've found two workarounds:
1) My Always On Display is set to turn on when I tap the phone. If I do that, the AOD works as normal, and if I then turn on the phone screen the phone screen works fine. This only works when Always on display is set to turn on on tap. It does not work if AOD is set to always be on.
2) If, when my screen is glitching out I hold the screen up to a reeaally bright light (like inches from a lightbulb), the rest of the screen turns on. It's weirdly green tinted and kind of stuttery.
Turning off automatic brightness does not fix this issue. If tried booting in safe mode and even factory resetting the phone. Issue still persists, including on screens like when the phone enters recovery mode.
The fact that I can get the screen working normally using workaround #1 makes me think this is a software issue, but the fact that it happens on the recovery screen makes me think it's pretty low-level. Any ideas? Anyone else had a similar issue?

I gave Samsung tech support a call and the level 1 tech I spoke with seemed to think that it was a software issue and that I should bring it in to be looked at by a technician. I'm in Maine at the moment and there's no Samsung or UBreakIFix stores within two hours, so she suggested taking it to Best Buy to look at. Not amazingly helpful or surprising.
If it's a software issue though... I mean this is my fourth Android phone and I've rooted and flashed ROMs on all the previous phones anyway. I don't want to lose Samsung Pay, so I'd rather not unlock the bootloader, but is there a way to flash the stock operating system or something? The exact model number is SM-G960U

It's a firmware or hardware issue not software as a reload* would have fixed it.
The firmware has been corrupted (needs reflashed) or there's been a hardware failure.
Best to send it in for repair or take it the a Samsung Experience Center as they can reflash the stock rom and have advanced diagnostic tools.
*make sure all system apks are running on factory load and have not been updated after the reload.
Updates, destroyers of worlds...

If that’s really necessary I’ll do it. But the closest place is out of state and when I called them said it would take 4 hours just to do a diagnostic. That plus the round trip... if there’s a way I can save some time, I’d like to.
For example, if one possibility is a stock firmware reflash, that’s something I’ve never done before on a Samsung device, but not very different from things I feel comfortable doing. I've flashed roms and rooted many android devices in the past. From a preliminary search , it looks like there's even a leaked tool online to do so from Samsung called Odin and that I just need to find the latest SM-G960U image with the right "csc" code for my carrier (I think TMB for T Mobile US). What would be even better is if one of those diagnostic tools you mentioned leaked the same way that Odin did.
Any recommendations on either diagnostic software or firmware reflashing? Or would you strongly advise leaving that kind of thing alone? I would like to still use things like Samsung Pay at the end of all this.

If it's under warranty let Samsung deal with it. A good tech with experience is invaluable.
Rather then waste time the extra ride might end up being the easiest solution. You could also next or 2nd day it to the center and back, make sure it's insured and packaged well.

That makes complete sense for something under warranty, but unfortunately my phone isn't. The S9 is about three years old now, and the Samsung rep was quick to tell me that the device was no longer covered. It looks like a mail-in repair service would cost about $175, which I'm theoretically willing to pay, but not if I can just handle on my own for free.

In that case you have nothing to lose by reflashing it. Hopefully that gets it.
Otherwise it be hardware... probably a good chance this actually the cause.
The good news is the 9's are available for a couple hundred in good condition if need be.
I was considering getting the 9 as a second phone (have the 10+) as the 10+'s haven't come down much in price.
Samsung current lineup sucks.

Huh. Well, before reflashing, I tried something I found other people suggesting for a related problem: https://eu.community.samsung.com/t5...t-bars-black-screen-issue/td-p/1745470/page/7
It's an app called OLED Saver. It's not perfect, the screen still has an odd green tint to it unless I use one of the tricks I was describing above. But I no longer have the issue where most of the screen isn't visible.
I might try reflashing anyway, will post results if I do.

Yeah, no joy. Reflashed by downloading the latest firmware using Frija for SM-G960U with TMB as the CSC, and flashed using Odin v3.13.3. If anything the problem is slightly worse now, but OLED Saver still mostly seems to fix it. I guess it's just a hardware issue with a weird software workaround...

Same type of brightness problem here as you describe, on my new S9 (G960U) - - Model starqltesq - CSS XAA
The product is under guarantee, but as it is imported from Hongkong to France, I don't have accesss to the Samsung local representatives and have probably to send it back to Hongkong ...
I will keep you updated if I learn something about the problem and the solution ....

Wiping the cache partition stopped this happening for me for around 24 hours but it came back this morning. On the Note9 forums someone posted that setting animations to .5 in dev options fixes this. I will try it.

Disable animations instead. It wastes resources. Personally I like seeing a fast, snappy OS do it's thing with no middle man needed. Lol, you end up waiting for the animations rather than the OS.

I've heard of people flashing custom roms and that resolved the issue permenetly, but can't find anyone willing to give some real feedback. I posted a topic asking this question, but haven't gotten any replies..

Not very helpful, but a work around could be to use Screen Filter

I temporary fixing my S9+ green screen issue by uninstalling the NFC module.
Unfortunately, this option make us cant charging the phone.
Maybe some one expert in hardware mod can do better.

Hey could you explain what exactly did you uninstall and how?
After uninstalling it wireless charing stopped working or what did you mean by cant charge the phone?
Did it fully resolve the green screen issue?

Some people noticed that problem after upgrade Android 9 to 10.
At this moment we have some facts:
1) OLED saver temporary solves problem
2) disconnect NFC module solves problem, some people on xda and on the yt confirm that
3) heating back cover using heat gun can help - I Discovered that some weeks ago
Interesting comment from the yt:
Sour Words
Sorry to say this, but green screen issue is a hardware fault not something an update can fix. One of the updates from Samsung is causing the CPU to over heat and in return permanently damaging the oled screen. Not only that but also compromising the battery as well. The only fix is the replacement of both the oled screen and battery. This repair is entirely the fault of Samsung due to a faulty update that over works the CPU capacity. Therefore my advice is for you to return your device back to Samsung and lodge an assessment request. They charge a small fee for the assessment, but the entire repair should be compensated by Samsung. Be firm and keep the pressure via emailing them to insist on Samsung covering the repair costs. My Note 9 is almost 3 years old when green screen issue happened. They fixed the entire thing free of charge. But I kept firm and didn't let them bully me into charging me for the repairs, which was their fault in the first place. I must admit, my phone despite its age, is in perfect condition. Not a scratch on it. Which I know contributed winning my argument for the repairs. So if you have psychical damage, I doubt you will have a chance. Good luck to all who will give this successful method a go.

When we disassembly NFC Module, the phone will give LOW TEMPERATURE warning. And make us cant charge the phone
