Sleep of Death on Mi4c - Xiaomi Mi 4C

Hi guys! A few months ago I bought Mi4c and got one little but very annoying problem: whenever I turn off the screen and ~1 minute passes its just reboots itself. Sometimes it goes to Sleep of Death(state when phone have no reaction on anything and can be rebooted only by 10-seconds power key hold). I tried everything: flashing latest MIUI from miflash and even from edl_download mode, its has no affect so I unlocked bootloader and tried to flash custom rom I've tried cm12, 13 by Teamsuperluminal, Ressurection Remix M, Mokee, etc. but problem still exists.
Now I'm use CPU Awake from Google Play to avoid my phone go to sleep mode, but it's not a solution.
Anybody know how to fix it?

I'm pretty sure that's a defective unit honestly. Have you tried contacting your reseller?

[Q] OPO constantly turning off and black screening

My one plus is constantly turning off. Never when I use it, i just constantly found my opo turned off in my pocket, or at the desk.
Till yesterday i was just able to turn it on and it was fine, but today it was turning on, but screen was black (not like not working, but displaying black color). For example, when i turned screen off, i could turn on flashlight with off screen gesture, but thats all i could do, so I get 350$ flashligt.
What to do? Is it possible to be software issue?
I too have been having this issue.
Pacman Rom 4.4.4, been happening since early october builds. TWRP at the time was V7, now V8 and still having issues with even the latest nightly. I've modified the performance settings and still no luck. VERY frustrating, Only happens on battery and never when plugged in. I've been thinking I'm the only one with this SOD issue and daily random reboot. Not sure I want to do a full wipe because I'm not fully convinced this is a software issue.
Anyone else having these issues?
you both should try fastboot flashing the factory image (then update again to 44s).

[Q] Touch not responding every few hours

Every few hours the touch barely responding, it takes me like 4 minutes just to reboot the phone, and rebooting is the only way to make the touch work again.
I tried to replace the the rom to cm12 nightly, change the kernel and modem. I even flash to stock cm11s and wipe every thing! And it still not fixed. Please help me!

this is no me but it is exactly what happened to me
Same problem here! Don't know if its related, but I just went on a ski vacation, so maybe the cold has something to do with it? Cause that's when the problem started.
The touch problem is very irritating when I try to unlock my phone, cause I can't draw the unlock pattern. Also scrolling trough photos or apps doesn't work cause it doesn't recognise scrolling, but does pressing instead.
I hope this is a software problem!
I use stock ROM cm 11. Did nothing else with it, I have my oneplus only 3 weeks now.

Screen backlight stays on!

Hello!
My oneplus one is having this issue for a while now, When I plug it in and lock the device, there is a 60~70% chance that the display stays on but its just blank, I have to unlock it and lock it again to fix it.
Recently this also started happening when it was not charging and the screen would often stay on causing massive battery drain :/
This happens on every single rom all the way from CM11S up to CM13 and also oxygen os,...
Does anyone know what the problem is?
Thanks,
Noahvt
I have the same problem since I can remember, also looking for an answer.
I have a similar issue. Sometimes the screen stays on, but is dimmed. A simple double press of the power button resolves it (turn on full, turn off screen) but its mildly irritating. I have only noticed it since being on sultanxdas cm12 ROM. I had an issue with a notification LED app not working since a recent ROM update so uninstalled it. Maybe the issue was related to that app as I cant remember the issue occurring since I uninstalled it a few days ago.

Issues everywhere, hardware problem?

Hi there,
I'm experiencing massive issues with the Nexus 5 of my wife. Everything is basically broken
It started 2 days ago, the phone start rebooting without reason and heating a lot. Applications sometimes hang for a long time, or the screen stays black with only the notification bar displayed.
Wifi is never able to connect, even though the welcome screen is able to display available wifi. On the welcome screen after a fresh flash, nothing happen when I enter the WIFI password and try to connect. Only the "ignore" button is available, as if I have done nothing.
LTE connectivity seems to work, but I have removed the SIM card for further testing, so it's hard to say.
Parameters screen sometimes works, sometimes won't. Battery consumption screen never works.
The phone is never able to shutdown properly, it hangs forever on the shutdown loading circle; I always have to hard-reboot.
I changed the battery (I had a spare one ordered few days before the problem occurs just to see if it improves the battery life), with no luck.
When I opened the phone to change the battery, it is clear the heat come from the CPU.
I tried (I wiped everything each time in between):
- factory reset
- flash a stock rom from Google website (MMB29K)
- flash latest Cyanogenmod rom (ZNH0EAO2NM)
I have the same issues with any of those 3 roms. I captured some logs while running MMB29K and ZNH0EAO2NM:
Stock (MMB29K) logs: https://drive.google.com/open?id=0B-CDc3nzF3e3M28tM2xjTmJKa28
Cyanogenmod (ZNH0EAO2NM) logs: https://drive.google.com/open?id=0B-CDc3nzF3e3TVUtTmExZDBLUms
The only state where the phone is stable is when TWRP is booted, which is not so useful...
I'm thinking of a hardware issue, but is there anything else I can try? What do you think?
Thanks a lot!
Nobody?
I said the same thing in another post. The fact that flashing different ROMs with the same issues kinda point to hardware problem. I'd guess something fried on the motherboard and it's causing weird behavior. Funny thing, the other post also reported wifi not connecting issues, so I'm thinking there is something that breaks in older Nexus 5 phones that cause wifi issues along with other random reboot problems.

Random reboots on some custom roms

I've experienced the same random reboots over the past few months across several roms. While on PiXeN OS (which sadly was discontinued) and OOS everything worked as intended, the reboots happened on PalladiumOS, EvolutionX and DotOS. Since the characteristics are always the same and I seem to be the only one having these issues it's probably something device specific that gets triggered by some roms.
After using PiXeN again for the past 5 months I decided to reset my phone using the msm tool to rule out any driver specific issues. Afterwards I did a clean install of DotOS and TWRP without Magisk.
I already tried safe mode, which didn't help either so it's not app related.
The reboots seem to somehow be connected to motion. They do happen when the phone is in idle and isn't moved but way less frequently (didn't happen on DotOS yet but it did happen on occasion on the other ROMs) than when it's moved. Whenever I move it my phone reboots after a while (seconds up to an hour), it seemed to happen a lot when being put in a pocket but playing around with pocket detection and wake on pickup did not fix the issue. Whenever there's sound playing the moment the phone crashes it will play a loud sound for 10 seconds without changing the pitch, afterwards the device reboots.
Any thoughts on what the issue may be?
