Weird charging behaviour. Flashlight comes on and full screen brightness. - Sony Xperia XZ Premium Questions & Answers

So this has only happened twice, but twice is enough. For some reason while charging the phone, the help screen comes on, the screen is on full brightness and the flashlight/led is active. No one has touched the phone whilst charging and it only seems to happen occasionally. Anyone else having this strange issue?

sounds like a defective device or a bug in the system. I would reflash and test again

Ghost presses when turning screen on (erratic)

Hello,
My Nexus 5 has been driving me insane since I got it (bought it used). When the screen turns back on, I get ghost presses anywhere on the screen. This happens sporadically.
I was able to pinpoint the problem by disabling the screen lock and running "multitouch Test". When turning the screen back on sometimes you can clearly see 5-10 ghost presses. The phone does not have a case, and there does not seem to be any pressure on the screen (else I would still see the press after turning it on).
This happens on AOSP or CAF based roms.
Am I the only one with this issue??
Is there a way to lock touchscreen input for 500/1000ms after waking up the screen (this would be a great workaround)?
Thanks
Is your phone charging when you notice this?

I tested this without charging.
I see. It happens sometimes when it's charging. I feel like it might also happen if your phone gets too hot.

Sounds like somebody sold you a lemon. I hope they transferred their warranty over to you.
My Nexus 5 is showing the same behaviour but only when I enable DT2W via any kernel. Can you confirm?
Sounds like water damage. Owned!

Screen Flicker / Dimming Screen

Has anyone else experienced the phone when first turned on being bright only to have it flicker after about 5 seconds and get a bit more dim? That's my biggest complaint with this phone. I have found out last night that while I had no lights on in the house it was not happening. Tried it again this morning and same thing. Works fine. But I turned on the lights and it happens again. I have the display at 100% with no automatic brightness. I hope it's not a hardware issue and just software.

Horizontal lines and now a black screen

My trusty old Nexus 5 has been showing horizontal white lines on the screen the past few weeks. Whenever this started to happen, it would detect taps in random areas on the screen or become unresponsive. Rebooting the phone would temporarily fix the problem. Last night the battery got entirely drained and now when I boot the phone, it only shows a black screen. The led at the bottom is flashing in white. Has anyone been able to fix this issue? I was thinking that maybe a LSD cable got loose, so it's fixable, but from what I've read it's likely that the LCD is broken?
I hope someone can shed some light on what the issue is and whether I can fix it or not.
Thanks in advance.
Was the phone every dropped? It could be the LCD or motherboard. I think the only way to really tell would be to move the motherboard to a working phone to see what happens when you try to boot.

Screen won't turn on G965F

Hello! I replaced my battery with a genuine one yesterday. The phone worked fine for a few hours. Then it started showing a white frame with a green line once in a minute. After that it progressively worsened in the course of two hours. It went through green screen with numerous green horizontal lines, completely black screen and a black screen with a few green lines. Now the screen is completely black and shows the lockscreen for a few milliseconds when locking/unlocking and now this is a permanent state. It is not going better. The only way I am able to use the phone now is through Dex and scrcpy.
The screen has no cracks and the phone has never been dropped. Which is strange, because it really looks like a hardware issue. There is no water damage as well.
I would like to know what may be the cause and I will be grateful if you could suggest any temporary or permanent solutions.
Currently I have tried the safe mode, oled saver, min and max brightness in the hope of being a software issue and still no luck.
Thank you in advance!

Are you certain that the replacement batter is the original OEM battery with the same specs and ratings as the stock battery or is it a higher rated aftermarket battery with "OEM design"?
If replacing your battery required opening the device and exposing the hardware to remove the battery, you may have damaged other parts of the hardware without realizing it.
From your description, your display is fried, probably due to the battery not being compatible or due to something internally making contact that shouldn't be making contact or due to the ribbon being damaged or slightly pulled loose while changing the battery and eventually completely disconnected after replacing the battery and reassembling the device.
Either way, it is definitely a hardware issue.

Screen flickering

Guys,
I've used the tablet for few times and this started to happen.
I mean it was noticeable few flickers when booting inside Android OS,but now I even get reboots.
So is it repairable or sadly throw this tablet to garbage which would make me sad?
I did googled and seems like common issue.
Could it be that happens when battery deplets below 50 %?

Why screen replacement?
I thought it's the battery or flat cable over it.
I would try the option "disable adaptive brightness," this would reduce the flickering to a minimum. What works is the disabling the HW overlays in developer settings but sacrifice deep color.
