Help me identify the fault - Android Q&A, Help & Troubleshooting

I was using my Note 3, just as normal, when suddenly a bright green line appeared down the middle of the screen and it will not go away. There is a second fainter line to it's right, but it is barely noticable.
The phone is also running a fair bit warmer, with the area around the rear camera particularly warm. Battery life is also down to a few hours.
I've tried a factory reset, changed battery, and the usual things.
Any idea?

Seems like screen damaged!
Have you dropped your phone?
OR
it must be bent through that point.
Your battery must about to die or can be a charger problem. Try to use original charger.
If factory resetting didn't solve your problem, that means the problem isn't from software.
Possibility is, you need to replace display+battery.

[Q] Green Screen Galaxy

I just picked up my S3 and the whole screen had a hazy green tint on the lock screen and was the same when I unlocked, and I wasn't gonna mess about so rebooted quick and back to normal now, and I read another thread about it but isn't clear why it happens, but I checked the battery graph and there's just a huge gap as if no power was getting through at all, so has anyone else had this happen on S3 and what's causing it?

Just had this, I put my phone into my shoulder bag, cycled for 10 minutes, picked up the phone and the entire screen was green as if the red and blue pins from a monitor cable had disconnected.
I'm also having charging difficulties, although that may be the cables.
I'm on CM9, literally just updated to the newest nightly now to see if that sorts any issues. There's something just not quite right about this phone of mine. A quick reset was all it took to sort the screen out but it was scary to think such an issue could occur.
All I know is it's something to do with a sudden dip in power and I read about other phones doing it too very occasionally, and after it happened there was a gap on the battery chart as if the phone was getting no power at all.
Sounds like the OS or at least an important process crashed or got stuck (deadlock, livelock, ...).
Green color has something to do with the rendering process and/or screen calibration. All Galaxy S1 with Voodoo patches for the display color values show a green screen for a very short instant after screen-on.
That also explains the gap in the battery stats since a non-functional OS cannot collect any informations.
Did you run any particular apps which might be causing it?
Without any details I can only recommend the standard package: flash your OS again, factory-reset it.
Maybe wiping the cache is enough. Maybe it's a hardware fault, hard to say...
I just rebooted and I've already upgraded since then, and I wasn't doing anything really at the time except I think that was around the time I used G L to SD and it broke the Play Store, but when it Hulked on me I hadn't touched phone for 40 minutes and that's what I saw when I woke it up. but most people say it's a once in a lifetime thing so not really worried.

Problems after battery replacement

Hi there xda.
I gave my phone to replace the battery. To a service that claims they know what they do. Everything was looking good after I got the phone back after an hour.
I left the city so I got to use a satnav and after a while I've noticed a yellow splash on the bottom left of the LCD. It gets more yellow when the phone heats up, and gets less yellow when it cools down, but it's still visible.
I decided to take it apart and the yellow splash/dot immediately disappear.
I've returned to the service but they ofc claim they did nothing wrong.
So I've got a question for you guys, what could they do wrong. When I took the phone apart, I've noticed a curbed cu metal plate over the battery, and got nothing under the battery, between the battery and the lcd. Sth should be there to isolate the battery from LCD or what?
Any help would be appreciated.
Thx in advance

feels bad for this brother. That may b because they hit the screen with a punch aur may b it Being pressed hardly.. even it may b they replaced your screen with old or used one rather than battery
well, the screen looks like the same, the glass has the same scratches.
so if they pushed it to hard or sth, there is really nothing i can do.

Hi, it may be that they damaged the flex cable for the screen, since my cellphone also heats up but the screen is ok .

it might be that it gets a bad display after it heats upa a bit, i'll try to add some copper by myself to isolate the heat between battery and screen/cables

Screen burn

Hey guys, can anyone tell me what the heck is this and how did I manage to get one after 12 months of using this phone?
edit] sorry for not explaining it, it goes along left edge of the phone, yellow mark near the charging port. I didn't notice it until yesterday and its visible a lot in live, I don't know how good can you see it over picture
hey guys, anyone?
Most phone screens go yellow from exposure to heat, perhaps your screen on that spesific are has been exposed to heat or preassurr

I'd say locked pixels but seeing it happen with phone turned off, yeah it's probably from heat.
I can also explain how.Sony uses a "liquid cooling thermal pipe" which takes the heat from your chipset (approximately below the N (NFC) letter on your phone's back) and delivers it to the left edge of your phone, towards the charging port to be more precise (your yellow mark is also at that spot)
You may have used your phone very heavily in extremely hot environment.I've seen my previous phone's screen go all weird due to heat (chipset @90 C) but it was fixed after a bit of waiting, to do this kind of permanent damage you must have used it heavily for long period of time, long enough to burn the screen via the heat coming from the heat pipe.
I doubt you could get it repaired for free, they would know it was because of heat and if your phone is unlocked, you have no chances at all because they can just assume that you overclocked your phone.

Mine goes yellow on the nav bar but only when its hpt usually when the battery is above 40°c but this occurs mostly when I'm charging
First of all, thanks for answering to all,
Second, you cannot see it when the phone is off, the first picture is with gray picture on it so you think it's off. When the phone is cold started, the mark is almost invisible but after some minutes of using it becomes visible.
The phone was never unlocked, neither was heavily uses, such as maybe gaming.
I just wanna know can I claim my warranty on it since I'm sure no pressure was made nor was it exposed to heat, but I first need to probably repair my cracked back screen.

NEW S6 Edge Owner needs some help :)

Hello everyone,
As the title suggests I'm now another proud owner of the Samsung Galaxy S6 Edge (SM-G925F) and immediately a few questions rose.
First of all, I unboxed my device and did the first power on. However, I noticed something weird. From the 1st power on it only had 3% battery ! Is this normal guys? From all of the unboxing videos I watched on YouTube all of them where 40% + after the 1st power on! Is it normal to be so low ?? So, I immediately shut it down and got it charging.
Second, after plugging it in to charge it started from 0%. Probably it even lost these 3% it had lol. Anyway, charging started nice and fast but I noticed another thing. The phone got really hot while charging! Is this normal again? The back was quite hot and the aluminum bezels on the sides as well (especially side lower parts). I know that this device has fast charging so it may be this and also maybe that it started charging from too low , 0% .
(UPDATE: now that it is at 99% it's has really cooled down)
My 3rd question is probably a foolish one but forgive me please. :silly: When I got it out of the box, since I'm a crazy perfectionist, I started examining the body of this jewel with a really bright torch light hahaha. Everything seemed flawless apart from a couple of tiny little marks on the lower left part of the home button. (not scratched some kind of marks like tiny glue residue maybe) They didn't get away after wiping them, even with little water on a cloth. Also, they are not really visible. Maybe they are a bit in really bright conditions but still you should look for them to see them. So, are these kind of tiny imperfections normal too? I guess so, but just wanted to say hahahha.
One more. My heart rate sensor seem to have a little plastic protector applied on it. Am I right? I'm quite afraid to pull it so, is there a little membrane there? In camera, I'm not sure.
Thanks in advance and have fun happy owners!
When I got my first smartphone, the Motorola Droid Ultra on initial boot it had 1% battery, so battery being low on first boot is not unheard of. Yet you are right that it should have 40% on initial boot. The battery going to zero before going up again is something I have experienced as well. The phone getting hot is expected with how rapidly energy enters the battery. The last two I am unsure about. If you can remove the plastic do so

Thanks for your quick response!
Alright, so yea the low 1st power-on battery seems normal. I also asked Samsung and they say it's normal since they don't set any specific charge amount from factory but they just use it as much as needed (for quality control, I assume).
About the heart rate sensor yea, I realized that it has a little protector film which can be removed.
Also, what I told about the little "marks" on home button let me explain. You can't actually see this normally. You have to have your home button fully clean and then point a bright torch to it and then look carefully on the bottom left part of it and you can see some tiny little "marks" but still can't see them at every angle. However, they are not scratches, it may just be some little debris or glue residue under the button surface, probably on the fingerprint scanner. (maybe during assembly) But again this is from a crazy perfectionist's eye! :laugh::laugh::laugh: You can't see it in normal use. I guess if you take many S6 Edges out of the box and start examining them with a powerful torch, mm by mm for sure you will find different kind of "imperfections" in any of those. This thing must be the same for every device. But I like doing it just to know if there's something there in the first place.
Also, about the warm up thing. I updated to Android 6 and performed a hard reset afterwards. Also I disabled fast-charging from the menu. (don't know if it's also disabled when you charge the phone fully shut down tho.) In normal use the temperature is fine. When charging tho (when shut down) it warms up quite a bit on rear and on side bezels. So, you S6 Edge does the same?
Thanks a lot.

Also, 1 last question (detail style again).
When you start up the notification led lights dark blue and then lighter blue in sequences. So when it does that, I can tell that there is a little "2nd" led that lights up on the right side of the notification led and makes it brighter blue. My question is that, can you see that in yours? I ask this because in my Galaxy Alpha you can't tell where the "little leds" are but you just see a clean light changing colors. On S6 Edge though, you can tell that the notification led area must be somehow "splitted" so like there is "another little led" on the right side lighting up and changing the color. Is it the same to you?
Thanks
The low battery percentage you had in your phone is just normal.
The phone gets hot when it's being charged especially when it starts from a very low percentage. Do you imagine the amount of energy getting into your phone's battery? That's a lot.
Speaking of leds, mine has the same too.
Hope you have a great time with your phone!

Thank you man. I noticed something else too though which worried me quite a lot. I will post it on another topic itself though so it can maybe be helpful for other owners too.

Screen start flickering when in charge

Hi guys,
when my phone is in charge at 100%, after some minutes it start to flickering when there is at least an orizontal black line and a white part, for example if there are 2 notifications there is an orizontal black line that separates the two notifications, right? The white part of the notification start to flicker. I tried to hard reset and nothing changed, and also got my display replaced and nothing changed (huawei customer service said they will replace the mb, but idk if this will solve my issue).
Anyone have this issue or it's really a faulty mb ? I tried searching online but it seems that no one have this problem.
I'll upload later a video that will show my issue...
Have you dropped the phone? Even from a small height it could cause problems.
My old p10 plus fell out of trouser pocket and hit the inside of door panel but was enough to cause screen flicker.
I had a hairline crack in digitiser/screen.
It only showed when screen brightness was on low or if phone was cold.
Got the screen replaced and was ok after.

I dropped my phone only 1 or 2 times and always with protection, but even after the display replacement the problem didn't solve. It only flicker when it's in charge and already at 100% and when I unplug the charger, it stop. I noticed this problem only after I got my display replaced for the gluegate... but even after a second replacement nothing changed. I hope after the mb replace, my phone stops to flicker.
I have the same flickering problem with my Mate 20 Pro and have never dropped my beloved smartphone. For as of right now, the current (.232) update may have resolved the issue but it's only been a day since the patch. I will see how it goes.
edit: nope, even after the (9.0.0.232) software update, the flickering issue still remains as the original poster has described.
