Hello everyone, I havent been on XDA in a while, but now im reaching out to the community. I am having weird issues Like overheating, "false screen starts", very dim screen, unresponsiveness while charging, camera buzzing, and bad camera quality.
For starters, The overheating is due to the Snapdragon 808 chip. It was rushed in development by Quilcomm. I disassembled my LG G4 to find that LG had put an RF shield on top of the CPU. Between the CPU and the RF shield is a thin layer of what looked to be mylar tape. I had an idea, what if I removed the tape and put some thermal paste between the shield and the CPU? I might try that as it wont really effect anything. Ill give you guys an update.
2nd: Screen issues. I have noticed when I turn the phone on from standby, the screen is very dim. Another thing that happens is the screen will be on but not show anything or have "static" on the screen. Both of which are very dark and hard to see in normal lighting conditions. This is fixed by putting the phone to sleep and turning on again. Someone in my family got a LG Vista and had a dim screen issue, but it couldn't be fixed by reboots. Another thing that will happen is a flash on the right side of the screen of multi-colored static. The flash is about half a millisecond, however it doesn't happen alot.
3rd: You know what happens when you try to use your phone in the rain? And how it does random things or even doesn't respond to your touch? My G4 has that issue while its charging. It happens most on my Samsung Quick Charger and as well as some non-quick charge chargers. This is annoying when I want to use my phone on a near dead battery, and is doesn't help that the Snapdragon 808 overheats when plugged in.
4th. Camera Quality: I think its the lens, I dont know yet. I noticed that very rarely it starts to buzz and you can feel it moving. Why? I have no idea.
Does anyone else have these issues? Please let me know. This happens on various ROMs (stock included). On android versions 6.0 through 8.1

Since day one, I've had touchscreen issues. When the charger is plugged in, the keyboard is unusable. One touch triggers keys all over the place faster than I could ever touch the screen. Unplugging the charger fixes that issue.
After a while, phantom presses start happening. If an app supports multitouch zoom, it becomes impossible to scroll instead of zooming. Keeping the screen clean seems to delay the problem from happening. If the problem presents, just cleaning the screen won't help. I have to turn the display off and back on for any effect. I've heard putting on a screen protector helps with this issue, but I haven't had a chance get one. If the screen protector just masks the issue, that doesn't seem like a good fix.
Should I try to get a replacement Nook Color now that doesn't have these issues or should I wait until the last month of my warranty to see if I can get more developed hardware? There doesn't seem to be a consensus if these issues are hardware or software.

That must be frustrating. Mine does not behave this way at all (though I've only had it for 4 days). If you bought it in the store, I'd exchange it. If you bought it via the BN ebay store, I'd try the screen protector first as I hear it's quite an ordeal returning it via ebay.
This us a very common issue. It has something to do with sensitivity of the screen increasing greatly when the unitbis charging or the screen brightness is way up. I just chage mine at night and don't worry about it.
I was having a lot of problems with phantom touches -- I even replaced my 2nd NC just to get another one that had the same issue. I ended up putting on a B&N anti-glare screen protector and haven't witnessed any phantom touches since then.
Edit: I actually meant to post this in the other phantom touches thread. ;/
Happens a lot to me even while unplugged. Known issue. Until I pick up a B&N screen protector I find locking the device and a quick wiping of the screen with a microfiber or any soft cloth (my shirt works in a pinch) removes moisture and oil build-up that is causing the uber-sensitive digitizer to register phantom touches.

Just picked up a second hand S4 Active. At times, the screen gets jumpy. It looks as though you are trying to swipe between screens. Also, it will at times go unresponsive. Touching the power button to turn the screen off, then turning it back on with power or home, fixes it.
I am going to take it apart to see if there are any signs of corrosion, and make sure the LCD connector is tight. I really don't think it has water damage, because the stickers are white. I suppose they could have been replaced.
I saw some youtube things that said a swelled battery could be the culprit, but the battery is not swelled at all.
Any ideas on this? It's a flicker - it jumps around. Turning the screen off and on fixes it, so I'm not really sure what the deal is.
Thanks much.
Should have added - it's on stock 4.4.2, if that matters.
When I put my nexus to charge, screen flickers like it needs more power. But when I increase the brightness it goes away or I can't see it. Tried a different power outlet as well. And I'm using the turbo charger.
Anyone experiencing this?
I just received my Nexus 6 and I notice a lot of screen flickering if I have the brightness set to low or up to 25% ...I see more flickering when I have the ambient lighting option enabled in settings. If I put the brightness to 50% or more it kind of eliminated the flickering...I am worried because I'm starting to question if this might be considered a defective display. Thanks
Yep, I got mine on launch day with T-Mobile. The screen flickers at lower brightness levels, at first I thought it was my eyes or I was just going crazy.
But it definitely is flickering, kinda similar to filming a fat old CRT TV with your video camera for your Halo 2 Super Bounce Montages (too a much lesser extent).
I'm a bit worried that it might burn out one day...
Also, my display is uneven.
I haven't looked into it yet, but maybe someone here could tell me -- should I contact Motorola or T-Mobile for a replacement? I have a feeling T-Mobile will charge me for it.
I get this too. Is it something we just have to live with?
I have had my Xperia Z3 compact for a bit over a year now, and experienced the "sudden death" problem a handful of times. The symptoms are pretty much the same as everyone else said: black screen, no response to power button, sometimes red light after plugging in but nothing on screen. Thankfully I have been able to revive it reliably by first holding Power + Vol Up for 20 seconds, release, then plugging in the charger.
After the last few incidents, though, I think I'm starting to see a pattern: the sudden death always happened after putting the phone on a metal surface. For example, the magnesium lid of my ThinkPad Yoga 460 laptop, or the (presumably steel) top of a washing machine. Every time I pick the Z3C up and notice it has died, it has always been lying on a metal surface before. However, it does not die every time I put it on a metal surface, so I can't reproduce the issue reliably.
I remember reading somewhere that the sudden death is caused by a hardware bug with power management. It sounds kinda plausible that being too close to a conducting surface may change the capacitance / inductance of something on the PCB just enough to trigger some kind of protection. So perhaps using a thick case may prevent sudden death by making the phone farther away from the surface it is placed on?
I have a D5803 that came back from being serviced. The touchscreen went bad, so the whole assembly (screen + sensor) was replaced.
Since you have to almost completely disassembly the phone to get to the screen, I suspect something went wrong during the repair.
The screen is flickering at random. By flickering, imagine a bad fluorescent lamp: you can clearly see the brightness varying vary fast, causing a flicker effect. Also, imagina a CRT screen. The flicker stops when you refresh the screen, like cycling through the home screens of your phone.
The guy who repaired it said it is a bad resistor that controls the current going to the panel's backlight. His excuse is that the board is very thin and fragile and that something might happened during the repair service. He also said that if he tries to do something else, the problem might get worse/something else might break. I suspect the screen installed is not OEM and is of bad quality. Sometimes the screen keeps autopressing as if someone was actually touching the screen, but not. Wiping the screen down on soft clothes (cleaning it) solves the problem. The screen probably doesn't have an oleophobic coating.
So, my question is: Is this guy right or is he lying (trying to push me ****ty parts/service)? How to know?
Also, is it possible to have a slightly smaller sized screen part? Because it feels that the screen area has decreased a bit (bezel increased somewhat). But since I do not use this phone since almost two years ago, I might be imagining things.
