MI A3 Random shutdowns - Xiaomi Mi A3 Questions & Answers

My phone would shut down at random intervals, several times a day, most likely when it's asleep and not being actively used. Sometimes I can power it back on, but it also happens, that the power button is completely unresponsive and it takes a couple of tries/minutes to successfully turn the device on.
Phone is completely stock, latest update is installed. No physical damage whatsoever. I've tried factory resetting, didn't help. Can't return the phone, 1 year warranty has run out.
How could I diagnose such a problem? It would certainly help if I could narrow it down to being software or hardware-related, but I don't know where to start.
Thanks, cheers!

Bro, i have the same problem, can you solved it?

[Help] Power button issue

I tried to turn the screen off, but it keeps turning back on. I've had this issue for a while and looked it up. Most people said it was a hardware issue, but the thing is...now it will not turn off the screen at all. I know the power button works because I can long press it to get the power menu as well as hold to restart, but not turn off the screen. Also, I can activate the "lock" feature in TWRP as well with the power button. I had this issue on an older rom, so I wiped EVERYTHING and installed revolt, yet I still had this issue and as I was typing this, I got the new issue of it never turning off. I don't know what's causing it. Any ideas? It's been happening for a few days now.
Attempt 2: Now I have the stupid turning off issue. Now, every time I press the power button the opposite happens. It turns on for a second and then turns back off. I'm thinking that this is a hardware issue. Anyone else disagree?
Attempt 3: Back to same issue, turns off and turns right back on in like 2 seconds. Going to call Samsung and see what this is about.
[EDIT]: I should mention, I have the same vibrate issue described in this thread. I'm suspecting a stuck power button. Great. Time to talk AT&T into giving me an early upgrade.
A stuck power button won't allow your phone to boot up completely. So you're probably ok there if you can boot up and type in an app.
You do have an issue though. Something got borked up somewhere. I would try going back to stock completely.
Backup important files, wipe EVERYthing on the phone at least twice. Then using Samsung kies on a PC do an emergency firmware update. Once your update completes perform another factory reset and see how she's working. If you still have a problem then contact Samsung. If no problem, enjoy your phone!
Eh, I tried the wiping everything (internal, not the sd card), but I guess I shall try moving it to stock as well. Do you suggest keeping TWRP or should I install stock kernel, recovery, and do a firmware update? I might also dump my phone in rice to see if maybe some water got in there (doubt it though). Also, I might be screwed if it's otherwise. Been over a year since I bought the note.
Also, are you sure it's not stuck (partially or sometimes maybe)? My phone is constantly rebooting on and off for no reason and sometimes this happens, other times the power button is okay. But when it does reboot, it vibrates a lot. Sometimes it'll just keep vibrating and never reboot like it's turning off and on constantly and I have to press and hold the power button a few times before it starts booting again.
EDIT: I also realize it could be a combination of issues and one of these issues might be a battery one. I do have another battery and I can feel a noticeable bulge so I'll go home, change the roms, battery, and do a firmware update and see how it goes.
Would just like to add that flashing an official firmware through kies did not fix my problem. Furthermore, now I'm getting the invalid sim problem and it keeps asking me to restart. I had this problem before and just recently (a week ago) got a new sim and now it's back. Maybe it's an hardware issue?

Motorola RAZRi XT890 broken - strange issue

Hello,
My RAZRi turns on, but is unable to access the phone. I have been researching this problem and there doesn't seem to be any solutions, this problem seems very weird.
So recently my phone has just been restarting itself, absolutely no idea why but it only happened rarely (probably should have done something immediately when this started to occur, -sigh-). The issue begun to grow more severe, as the RAZRi was restarting itself more frequently and was becoming a nuisance as I may have been doing something at the time.
I had a theory that the problem may have been something to do with the battery. There was a couple of occasions where I would be charging my phone and I would remove the connector to then notice that the phone resets a couple of seconds later. The problem was getting more serious.
The phone has now entered a stage where I can't even access the phone. By which I mean it keeps resetting itself on the boot-up process, in fact this is happening as I speak. I have been unable to access my phone for the last 2 days and this is really strange. I tried booting in to safe mode to perform a hard reset but I literally can't do that as the phone just keeps resetting itself.
What the hell should I do!?
Thanks,
James.

That's certainly not good. :/ Is it able to stay on at all, like if you boot into recovery? If it won't stay on in any mode (fastboot/recovery/OS) then without trying a new battery first, there won't be much else to try. If it's rebooting itself that quickly, in any bootable mode, then there won't be much else to do because if you try to SBF the original software back and the phone reboots in the middle of flashing, that could be a surefire recipe for an unrecoverable brick. I haven't worked on an i before, but for most Razrs the batteries aren't THAT hard to access. Generally it involves a couple of Torx screwdrivers, removing the 2 bottom screws, sliding off the back, and undoing some of the screws around the outer shell to give access to the battery terminal. I'm sure there are a few guides lying around either here, droidforums, or just YouTube.

Zperia Z5: LEDs Flash, Then Phone Reboots

Random Crashing
I am experiencing random crashes where the phone stops and the LED flashes a few times before rebooting. At first I thought it was overheating, as the phone was quite warm the first few times, but it has just done it when cold. It has happened mostly whilst in the play store. It's crashed about 15 times in 4 hours.
Has anyone else experienced anything like this? Is there anyway to access the logs without root?
*** Edit ***
This must just be a dud device. I did a factory reset last night and it crashed rebooting. Will take back to shop and hopefully exchange for a new one.
Did u tried to repair it via PC Companion?
It comes from a bad battery voltage. I had One m7 and after 1 year this problem begin. They change the battery and battery conector and it comes to work good.
This happened after 5 minutes, it's been sent back to the shop now for repair / replacement. Shame, as it was a nice phone when it wasn't crashing!
I had kind of the same experience with my device I bought yesterday. Turned it on, worked for about half an hour before flashing the red LED a few times and shutting down. After that it turned on once again, booted halfway up, the red LED flashed again and it shut down again. Then it did not react to anything anymore.
Plugging it into the charger did not yield any reaction at all. Pressing On and the Vol+ button made it vibrate three times as its supposed to do, but afterwards even that did not work anymore. As a last resort I pressed the hard reset button in the SIM slot, which also made it vibrate three times without any other reaction.
So I concluded it was dead and returned it to the store this morning to get my money back. I think I will hold of of buying a replacement until all the errors that currently pop up are sorted out.
Also noteworthy is, that while booting up and in the time it was usable the screen had a red tint sometimes and touch was working rather flakily.
They sent me a brand new phone, so was def a dud. No crashes so far, finger crossed

Galaxy S3 Freezing. Help

hi all,
i have a very unusual freezing problem that is driving me nuts. i have read loads of posts about people using dummy file generator, clearing defaults, factory resetting etc. but my problem remains after all of the above.
here is what happens with my device.
device is galaxy s3(gt-i9300)
running stock vodafone branded but open to all networks 4.3
baseband i9300buugnf1
build number jss15j.i9300xxugnh4
the problem started back in october last year. the screen would freeze and the only way of getting it back would be to hold the power button in for about 10 secs, or pulling the battery. i tried leaving it overnight to see if it would unfreeze itself, but no joy.
this was just occasionally to start off with, but has now become too frequent to allow the phone to be usable. sometimes the phone would go for about 20 mins without a freeze, but other times it would freeze after just a couple of mins.
sometimes, when i reboot the device, it freezes on the samsung logo, but the logo still pulsates as if it is still booting up. but never does. it also freezes when turned off and charging. i have to hold the power button in for about 10 secs again to get it to start up.
the phone is out of warranty. i did have a problem with the phone over a year ago and sent it away to samsung, where they changed the motherboard as it was force closing all my apps. but just after a year of it working perfectly, this happens. it seems samsung have put a self destruct timer on their devices. lol.
has anyone had the same sort of problems, if so did you manage to fix the problem?
any help with this would be greatly appreciated.
Thanks

HTC One M7: Power button doesn't work, but only when screen is on?

So about 3 weeks ago, I dropped my HTC so now I have a large crack running down the middle of the screen. However I haven't had any other problems up until last night. The ringtone volume turns itself up without me even touching the phone every now and then and once it does that, the power button stops working. But it does work again once the screen is switched off, meaning I can turn in on but not off. The power button functions fine until the volume button acts up the first time after restart.
I factory reset my phone thinking it may have had something to do with the software but the problem came back within the hour when all the updates started rolling in. Once it did, i booted it into safemode and the problem seemed to stop but I don't know what's causing it. Could it be an actual bug in an update or is the damage to the screen simply too much for the phone itself? Has anyone ever dealt with a problem like this? Any help will be appreciated as I know it's expensive to fix these things and I don't want to go to the shop to get it fixed only for the problem to come back as it's software related.
