Got this phone, but it has odd fault. If phone is not connected to charger, it power off after few seconds screen goes off. If it's connected to charger or using application to prevent screen to go off, phone stays on.
Battery is full and I've used it empty once. Phone reset does not fix problem
Phone is naturally unusable as a cellphone now. Have you ever seen behavior like this before?

Is there anything I can do myself?
Reset and flashed phone multiple times, fault stays. You should avoid Oukitel.
I just lost 200€ buying faulty phone from Aliexpress. :/

Hello,
recently, my 7Pro drained all the battery and turned off. When I got home, I plugged it in and waited to finish the charging. After 20 minutes I noticed that the phone powers on, put the announcement that the battery is critically low, stays on for about 3-5 minutes, then turns off itself. After that it shows big battery icon on a screen and nothing is happening. Again, when I plug the cable out and in again, the phone starts and behave again the same (stays on and then turn off by itself).
Does anyone encountered similar problem? Could it be faulty battery? I've tried 3 different chargers (including car), tried to charge it from my 2 computers, tried charging while in bootloader mode, also I've reset it to defaults (+; - ; power). Nothing helped so far.
I have it still in warranty, but I have cooked ROM made by ansar. I'm a little afraid to send it like that to HTC.
Any advices greatly appreciated!
Thanks!
OK,
I will answer myself
Do not give a phone to your younger brother! Little brat somehow changed USBMode to "diag" and uninstalled the app! I have restored the phone to defaults and managed to check that before it turns off. After switching to Zune mode, the phone is charging without any problems.
So anyone having similar problem might want to check it out before panicking like me.
I recently dropped my phone on the ground and the glass is now broken. But it worked normally for about 14 days. Then suddenly one day at work it shut down on its own. After that I wasn't able to start it. No reaction for any of the buttons, nor their combinations. Even when I plugged the charger in, no sign of life. I thought it's over.
Then the next day, I plugged the charger in and the screen with 0% battery appeared. So I left it charging, but when I came back to it (20 minutes) it was dead again. Not even the diode indicating it is charging. Again no response for the buttons, nothing. So I tried to disassemble it, disconnected everything. Put it together and viola! The screen indicating 0% battery was there again. I left it like that for a while, and when it was charged a little, I tried to start it. It started and normally worked. At least it seemed to, but after a while (1 - 3 minutes) while I was using it, it went to the dead phone again.
So I discovered, that when I disconnect the battery for a while and then connect it again, I am able to boot the phone. I was even able to do factory reset. I thought I got it and that it was some software fault. However after like 5 minutes (it downloaded all apps, logged to my google account, looked all ok) the screen shut down again and again the phone played dead.
Now I have the phone booted, and charging (almost 100% now). But I guess when I start using it again, it will again go to the dead mode (since it did it everytime after I used it a little, no specific action done, totally random).
I guess it has to be related to the broken glass. Maybe some water or humidity got through it and the phone is trying to save itself from damage by going to the dead mode. It's weird because sometimes (like now) the phone is OK when not used, normally chraging and not shutting down (now it's ON for about 40 minutes), but if it shuts down, it takes about 3 or 4 battery disconnect and connect again, before it boots to the main screen. Sometimes it just dies before the screen, sometimes it dies when I try to plug the charger in, really no idea what causes it.
How should I diagnose it? USB debugging and check the log when using it and when it dies? Or has anyone experienced this too? Or could the battery be damaged? Or can I somewhere set the phone to prevent from selfkilling actions? Today I will try my main board in my friends G Flex 2, to see if it's the board, or something else.

OK so it was probably mother board fault, so I had to buy a new phone It is like 3 months, and I just yesterday accidentally poured some water on it, so i destroyed another one. It is still in warranty but I guess with water damage there is no warranty. Anyone knows where to find all the water damage indicators? Or is it even possible to make it look like there was no water damage?
So,, first of all, hello everyone! I'm new, I'm not a device-proficient, and I'm in a problem with my phone.
This might get complicated.
So my problem starts just some days ago. When I am charging my phone with a tablet charger, it now stuck on the COOLPAD screen when plugged in. It bricked itself, but if I restart boot the phone it will turn on and goes normal, so I turn it off again then charge it with an appropriate charger. And it works and charges. Although that usually the tab charger didn't do this to my phone before.
But then.... That's just the start.
When I booted it on after charge fully and then turned off for some hours, it will boot, but no sound coming when booting on COOLPAD screen, which indicates a problem. The booting on the screen of that takes long, very long then when it's On, surprise surprise the wifi can't connect to any nets suddenly, Sim card cant be read (indicated as No Service) , SD card not detected as well(also indicated as No SD card) . Seems like a malfunction. I had experience the same before 5 months ago (and it goes semi-perma so I asked Coolpad center for software reinstall).
So what did I do? I restarted the phone through the Chinese recovery mode. Booted up right, and back to normal. But this happens just when I boot it on morning now. I am scared this might get worse and will completely bootloop or brick my phone in the future (just like the same problem I face some month ago).
So should I never turn my phone off again or is there a fix for this? Tried factory resetting it in the past, the problem just got even worse so I won't do it again the third time my phone is broken again after software reinstall again. Please help, can't really switch phone until able to find a very reasonable priced ones.:crying:
NOTE: Some day before, my Coolshow app got disabled by Play Store because of "danger" reasons. It is a system app that comes with Coolpad. I can't enable it again because the enable app isn't there, just a greyed out Disable button. I don't like to reset the preferences of apps because it'll make me need to set everything up again. Problem already occurring 3 days ago, till now.
Hi,
Last Thursday night my pixel 2 became unresponsive, I rebooted and it worked again, then it became unresponsive again, I rebooted but to no avail. The phone does have a large chunk of glass missing in the bottom left below the screen (https://drive.google.com/open?id=1NdlE-Xrwa9rPPGpMXT47FHqLWfW0MHd2), this happened due to a drop some time ago. At the time I tried booting into safe mode which didn't help, I also tried to go into recovery mode to factory reset the phone to rule out any software issues, but the phone wouldn't enter recovery mode, it just would go straight to the "google" logo and then would boot loop and sometime it would break the loop and just boot as normal. This unresponsive behaviour has been demonstrated before, but a reboot sufficed.
As the phone appeared to be functioning otherwise, I decided to order a replacement screen (I haven't received it yet), although I do find the ability to not go into recovery mode concerning.
Also, when I say unresponsive I mean just to touch, the fingerprint reader still lets me pull down the notification bar; the phone is not frozen. One final thing and I'm sure if it's related, is that I was getting some crackles and pops when using my headphones with the provided 3.5 to USB C, I assumed it was down to the cable getting damaged, but it might also be to do with phone's damage.
I hadn't touched my phone all weekend, I turned it back on last night so my alarm would go off this morning. It did and I was to my surprise responsive. I left my phone to sit on my desk over the weekend and I believe the battery drained completely and it turned off, I'm not sure if that complete battery drain was the reset it needed or what. It was definitely unresponsive for half a day of me rebooting, but who know how long that would have went on for.
I'm not sure now if I should replace the screen, I think I will just due to the physical damage the phone has, but I would want to return the screen if the phone is on the brink of being unusable regardless of the screen/digitizer hardware. As clearly the hardware does still work.
Any advice/help would be much appreciated
Hi. My close friend has this issue. I'm posting this because she can't figure it out by herself. A month ago, her phone downloaded an update and she installed it. Since then, the phone has restarted by itself without any reason, just random restarts and the frequency of restarts was more frequent with each day. Fast forward to this day and the phone is constantly turning up and shows the POCO logo and restarts by itself. This loop is not ending until the battery is completely dead. When trying to access fastboot or recovery mode, she can get there but only for few seconds (until the device restarts again) which is not enough time to make any changes / factory reset. She did not accessed developer tools in system, so the bootloader is still locked. Holding down power button does nothing. ONE SINGLE UPDATE screwed up whole phone. Can't do ****. There's no SD card or SIM card in the slot. Is there any "hack" to stop the phone from restarting itself? Note when the battery is completely empty and she plugs the charger, the whole nightmare starts again. I'm lost. Did you guys have any ideas what to do? Or is the repair centre only solution? (She cracked glass of the display, i'm not sure if that voids warranty. [it's not glass COVER, it's the glass which is part of the display])
Is this device unlocked? If not, then RMA.
If it is, my best guess is to get the device into recovery (or fastboot?) and immediately connect to PC.
If it holds, leave it there as it will charge, although at much slower rate.
When charged, use TWRP to try to reboot to system.
If it doesn't work, then factory reset.
Sadly, i can not get to recovery because in about 2 seconds the device will reboot. There's literally no time to make any changes - factory reset. Also the device is not unlocked. I hope RMA accept the phone even though it has cracked screen . Thanks for response anyway
Then RMA it is. If you're in EU they'll have to take it, even with the cracked screen.
But does the reboot happen even when connected to PC? Two seconds is enough to plug it in if you're fast...
Yeah, we tried every possible idea we can think of. Pressing the toggle button from different angles with different intensity to make sure it isn't stuck inside, covering up the proximity sensor (yeah makes no sense but even that we tried, lol). Tried with connected to PC as with classical charging brick. No change. Back in those days where smartphones doesn't have unibody construction and you were able to take down the back cover and remove battery it was way simple. Nowadays it's not possible to stop the phone from booting itself until battery is completely empty. My friend says the problem started about month ago, when the phone annouced that there is an update available so she downloaded it and installed it. Before that, there was no problem with the phone whatsoever. Maybe it's caused by some kind of virus but IDK which apps she was using. She didn't have rooted phone not unlocked bootloader in developer tools. Also i googled that it may be caused by "Airtel Thanks" app which she didn't have installed aswell. I will keep this thread updated as what happend to the phone cause i'm also interested what went wrong and to help future users who will struggle with this problem a solution. Thank you.
CaptainFedora, did you solve the problem? I have the same issue...
Yeah, actually. Sorry for not posting the answer although it was definitely her fault. It was the power button being pressed down (which made continuous bootloop). But the button was somehow pressed deep into the phone's body. So complete dissasembly was needed.
Btw. my friend lives in other country so we discussed this problem over internet. If i could have the phone physically with me i would definitely know what was the problem.
Hi.
Yesterday I had the same problem, the device kept restarting every 10 seconds, it didn't even come to any screen besides the first one with the POCO logo in yellow.
Things I tried that did NOT work:
restart
hard restart
fastboot (it did enter the fastboot mode, but only showing the picture of the 2 robots and after 10 seconds restarting again to the POCO logo image)
plug it to power
plug it to computer
After 3 hours of continuous restarting and trying anything I could find in the internet and I could imagine of (except extracting the battery because it seemed complicated and difficult to revert), I tried randomly something that miraculously worked...don't ask me why.
pressing the power button shortly and quickly around 30 times (it might have worked after 10 or 20, but I just kept doing it a little longer
Afterwards it just started as if nothing had happened...doesn't make any sense, but I just wanted to tell you in case you are in a similar situation and desperate to not lose all the images and videos as I was yesterday.
