Mi 9 lite switches off for no reason? - Xiaomi Mi CC9 / Mi 9 Lite Questions & Answers

Bought a Mi 9 lite from amazon Spain on 26th February. Everything was working fine up until 2 weeks ago. Now, every few days, it just turns itself off for no reason. I have to hold power button to turn it back on it then gives me option to reboot or wipe data (which obviously I don't want). Then I press reboot, using power button, and it reboots. This has happened 4 times over past 2 weeks. Any ideas whys this is happening? Any fixes? Thanks

Got a Nook + for Xmas 2013 3 days later its knackered

Got a Nook + HD for Xmas after looking at great reviews for the tablet. Sadly just 3 days in my device is rendered useless.
It was working fine until an hour ago, i had done nothing to the device that was not forced upon be when i first turned on the device. It was just running stock everything.
The only app i had installed was iplayer. I was using the inbuilt youtube app watching some videos and it just died. The device was just off a full charge so i know it was not that. The screen backlight seems to work when i press the on button but nothing else. When plugged in the chargelight is green for 2 seconds then orange for 2 seconds then it goes off.
Ii have tried holding down the power for 10, 20 and 30 seconds with no joy and have tried all 3 while holding the home button again with no joy.
Anything else i can try before returning to John Lewis?
Thanks for any help offered
Since you did nothing to it, I suggest you exchange it at B&N. But if you want to try to fix it yourself, go to my HD/HD+ CWM thread linked in my signature and make a bootable CWM SD and use that to flash a plain stock zip from item 6 followed by a factory reset with CWM.
Or you can interrupt the boot 8 times in a row and it should reset itself to factory ROM.

Screen does not light up - Mi max 2

Hi everyone;
I bought a Mi max 2 last month and I was very happy with it . But a few days ago the power button does not work to light up the screen. The phone is on, it rings when I receive a call but when I click power button to unlock the phone it doesn't light up. It seems to be a delay because sometimes it works but other times it doesn't.
I've tryied a temporary solution found on the internet by rebooting but the next day the problem came back.
Anyone has any idea?

Screen Blackout!

Recently, I've noticed that my phone's screen completely blacks out while the phone is still working. So, if you plug in your charger, it'll play that charger connect notification sound if you use the fingerprint, it'll unlock the phone but nothing comes up on the screen. It'd be completely blacked out. This has happened to to me twice and has me got worried now. No matter for how long you hold the power button, nothing happens. Right now, it seems that the phone corrects the default by itself after leaving it aside for a good 10-15 minutes. Has anyone of you faced this?
Yep, unfortunately happens, though rarely . Mentioned in few other threads.
Happened to me thrice. Yesterday was the last go. You can reboot with Vol up + power.
It's an annoying bug, I'll admit that.
For me the same, two or three times last two weeks, I think some bug in Pie, because before there was nothing like thies

Have had this phone since its release date here in UK (TA-1055) and have not experienced black screen or any other bug, except the non-appearance of Pie which has still not Ben released in UK OTA.

Experienced it thrice. The first time I experienced it was last August (Android 8.1 Oreo), then October and today. I didn't think this was the new Android 9 Pie's fault as I experienced it when my phone was on Android 8.1 Oreo. Also one thing I noticed is that even if the screen is not showing up, the touch controls are still active. So I managed to restart it normally my phone by press hold the power for a second and feel the default location of the restart.

Mine would just not restart. Or maybe I was touching the wrong portion of the screen... Afterall, it was all blacked out
Same, holding the power button vibrates the phone and touching the screen does make it vibrate sometimes, but Vol up + power does not do anything. Screen is still black.

It happened to me last month for the very first time and hopefully will never again in future!
I can't recall if I was pressing the right key combination but for several times it would just vibrate and then nothing. I had to call customer care from my secondary device to check what can be done who were pathetic to tell me to take it to the nearest service center. Then, I eventually tried the Power button + volume up and then it rebooted and went back to normal.
I was so shook with this incident, I hope it never happens to anyone. I've been using this device since 7 months now and it never happened to me when on Oreo. This device is getting more and more pathetic with each new update!
Hi,
sorry for necromancing the thread. It happened to me today too, for the first time. If anyone else stumbles upon this thread, then this is absolutely easiest solution:
1, Hold down power button until it vibrates
2, The screen is black, but the touchscreen still works. The easiest one to touch is the power off button, because it is right next to the power button So simply tap on the display right next to your power button after you feel the vibration, and you will tap the power off button. Wait a few seconds, then hold power button again to turn the phone on again.
Same happens to me. I hold down the power button until it vibrates, release, take a deep breath, tap button again and it is back.
Happened to me as well ?
Hi,
I just bought this smartphone nokia 7 plus TA-1046 4G/64G dual sim. I could parameter it and after only 2 hours of use: total black-out! I could still feel vibrating keys despite the black screen. I ve been able to force the restart by pression power button + sound level up, but the screen remained desperately black. I tried to charge it well for 1 hour, same ****. Surprisingly, I removed the sim card and the SD card and It restarted normally.
Pretty scary! Will it happen again? What was the pb? A SD card conflict? Shall I format the SD card maybe? Or buy a top quality SD card? A sim card conflict? Shall I keep the phone or send it back to the shop?
Did anyone narrow down a potential SD card cause as well for this kind of glitch?
Thanks.
Arn
Happened to me also couple of times.
One time happened just before I wanted to show off my phone to my friend. I had to keep my phone in my pocket for like 10-15 minutes, lol, I was embarrassed because I praised this phone, and praised Android One, because he was considering this phone to buy, for at the end he went with the P20 Lite.
F***you HMD
Re happened again
Just 1 hour ago my nokia 7 plus re black out again! Had to wait 1 hour to re start it. Then, it worked 5 mins and black screen again. That s enough => I ll ask for a product return and refund.
Btw: i don't have blackout problem using daily N7p for 10months...
Have you guys tried formatting the phone ? I had clearing cache issues when I set font size and screen size small. It will clear the cache very slowly and eventually it will struck. But it was solved after I tried default font size and display size. Looks like every model got its own issues.

Note 9 black screen with power still on

I purchased a Note 9 (unlocked international version) in November upgraded from the note edge. I also ordered the galaxy watch (also international version) last week, upgraded from the gear neo . I received my watch and decided to pair it to my note 9 immediately however it was a disaster.
During the setup procedures when the necessary updates were taking place (at least I figure that's what was happening) more or less the watch displays setup mode and the percentage is displayed on the phone. During that period I received a call, answered, talked and hung up and placed the phone down for the update to complete. When I took the phone up to check the progress the screen would not turn on. The phone is still on because the notification light is blinking and messages and calls still come in but the display just won't come up.
I've tried restarting with and without the charger connected but the screen still doesn't come on
What can I do?...Think I'm about to lose it.

Thanks bober10113.
I tried this but it didn't work, my timing might be off. I'm going to try a couple more times and see what happens.
If this doesn't work, is there a way I could flash the phone to get It back to normal?

Looking for blankflash file for Amazon moto x4 with april patch.

As the title says. i had one of this phones, and i ended up sending it to motorola, and they send me another one, wich it lasted me one day, now i did ask on another topic if someone could help me to get the files out of the phone to help the comunity but i didnt got a responce. Now that this phone its in the same situation i wonder if someone can help with such file in order to fix the phone. thanks for any help, and pardon my bad grammar. moto x4 Amazon prime 1900-1 32gb with april patch.
me too
I managed to start the phone by just using two rubber bands ,one in the minus volume on other on the power button, set it for at least 5 hours, after that plug your charger, and it should boot into fasboot, just select start and phone should work just fine, sometimes I don't even need the charger I just release the power button ruberband then wait for 10 seconds , I press the power button again for 10 seconds and the phone starts in fasboot mode, I select start and all works again. Last time I just waited 2 hours, I know it's a solution that sucks ass but until someone comes with a real permanent solution ,this would do. I also flashed latest rom but the problem persists. I'm on may patch now and it happened to me last week. Good luck. Post results if you try.

I started a new thread on this but though I might ask here as well. Is the goal to drain the battery by holding the buttons? Also, after 5 hours do you remove the rubber bands and then plug it in or keep the buttons pressed? Thanks.
