[Q] Z1 screen flickering - Xperia Z1 Q&A, Help & Troubleshooting

2 days ago when putting the phone in the water afterwards the screen started to flicker, closing it for a while decreased the frequency of the flickering however this did not resolve it, I did the device tests which came out fine however the brightness is stuck and increasing/decreasing it won't make a difference, touch is operational. Phone is 4 months old, software updated a week ago (did not put in water since), have yet to try restoring. Help is appreciated!

Put it in a bowl of rice for a day. Maybe water somehow got into it.

[Q] Rebooting and Drain problem

I've been ROM-free for months now ever since this problem started but alas! Not even returning it to the stock using Sony's repair thing fixed it.
My phone has been rebooting at random moments and whenever I'm lucky enough to see it on, the battery status always changes. For example, I've recently charged it then put it in my pocket for a couple of hours, when I check it, I see the Sony Ericson logo and when it turns on the battery has completely gone from 90 to 20 something if I'm lucky and 3% or so if I'm not. This problem is often found when: I've left it in my pocket for even the slightest period of time, when someone's calling me (I can't even answer calls for more than a few seconds now because it always dies on me), and other random moments.
If it helps, the battery seems to be on fire every time it reboots itself. Thanks for any helpful suggestions and even for just reading.

Screen mysteriously broke, now overheating

My phone has UB and been using different custom roms, but nothing outside of stock roms. I never overclocked it, but the top half of the phone would get warm from normal use. After using it for about a half hour I put it on the bed, with nothing else near it. I was the only person in the room, and after 10 minutes, I picked up my phone and realised the screen was broken. The phone was cold, so i realised my air conditioning was directly blowing onto the phone for the past 10 minutes. So i assumed, it was the hot and cold mixture that caused the LCD to shatter into 5 hairline cracks.
I recently carried it to a very good technician, who replaced my LCD with a witrigs.com replacement screen. He did a very good job, but from day 1 i've noticed the upper half of the phone gets hot randomly throughout the day with little use. The longer I keep the screen on, the hotter the phone got, and sometimes i would use the phone for long periods without it getting extremely hot. Today I tried to use the camera in broad sunlight and I got the error that the camera had to close to cool down my Xperia.
Does anyone have any tips as to why its over heating or what could solve it? I've tried different roms and kernels but nothing changes.
You can see at the bottom of the phone is where the crack started and it split thruout the entire LCD
Hello, my z1 was also heating by normal use. Then the screen broken. Why ever.
Yesterday I got my new z1 from the provider. No heating (I play Ingress) all things fine again

Reboot/shut down while on standby/sleep

Hello guys. Recently my phone has been acting up. It's been rebooting or shutting down by itself while not in use(standby/sleep). But this issue doesn't happen at all while the phone is in use. I tried to reflash everything from scratch but it's still happening, even when I'm on stock. Hardware failure imminent?
One thing is, about a week ago, when I put my phone to download stuffs overnight, I found it suddenly getting REALLY hot after just 2 hours or so and battery completely drained. I shut it down for itself to cool down before charging it. It was ok for a couple days than the issue I mention above started happening. Oh yeah, and it's getting hot easily now.
Any idea, anyone? Is it really hardware issue or anything I can do software wise?

Submerged redmi 9 still alive - 4hrs underwater

Hi there. Unfortunately, my 6 days old redmi 9, under a tragic but also hilarious circumstance, was found at the bottom of a 2,5m deep well full of water for about 4 hours!!!!! Do we have a record here or what?
As soon as I got it out of the water, I have rubbed its circuits with isopropanol and I dried it out for about 48 hrs using a dehumidifier
Now, 20 days since, it still works quite well... The screen has lost a lot of its luminance, but despite that seems fully functional!
BUT...
The only issue I cannot handle is that, as soon as the screen gets off, the mobile is repeatedly rebooting. When the screen is on, everything is OK!
Damn! The only trick I found to make my phone usable is letting an app working in the background while the screen is off. Yes, this is working but is battery-consuming. For this reason, I used a music player (misicolet) in an endless repeat mode.
Any ideas guys???
