Facing strange Black Screen Problem even after booting of the Phone successfully - Xiaomi Redmi Note 4 Questions & Answers

Hi,
I'm facing a strange Black Screen Problem even after booting of the phone successfully every time. I can see the lock screen every time for like 2-3 seconds then suddenly entering to black screen automatically if I try to unlock or don't attempt to do so. The phone is able to ring if I try to make a call from other no. but won't able to pick up because there is no option to answer or decline the call. If I hit the power button all power menu buttons are coming like to reboot, power off , airplane mode etc but some how I'm not able to access the phone from inside.
Please note that last time when the phone was running fine I saw one error like android.system.mui has stopped working and everything was crashing so I had to reboot my phone and ultimately landed into this issue. Also my internal storage was like 600-500 MB free that time.
I'm on miui 9 official for Redmi Note 4 ( 32GB version SD 625).
I'm a new member of XDA and I haven't read all the rules yet, so I apologies if I do any mistake please correct me if I'm wrong as this my first post in XDA. I respect all the community guidelines.
Please provide the working solution for this.
A few quick questions as follows
- Do I have to install TWRP recovery for the same to clear cache which i think it may resolve the issue just removing the cache?
- I'm not sure about Miui recovery 3.0 clear data option to clear cache as i don't really want to erase my all important documents, photos, videos, notes in my phone.
- How can I recover my data if I had to reset my device ?
Please guide me for the above issue.
I really appreciate all your concerns.
Thanks & Regards,
Gaurav Kumar

I have exactly same problem, please help with solution.

Are you able to boot into the recovery and use it? Or does the recovery shows the black screen also?

hey I`ve just got the same problem in Redmi note 4, did u find any solution?...
so far what i did till now is, flash Red Wolf Recovery, wipe, DALVICK, CACHE and DATA (not the internal storage where is your info), the wipe is like a factory reset, is the only solution I`ve found so far.
any ideas?

Do you have a unlocked bootloader? If you don't then possibly resetting device from recovery is the only thing.

Does this issue already solved? I also have the same issue but I don't know how to fix it. Please help me

HI
I have the same problem, I tried using the fastboot (power+volume down) and nothing happened, I tried the recovery mode (power + volume up) and I got three options, (reboot, wipe data, connect with mi assistant) the first would reboot the phone to the same problem, the second one I don't want to wipe all data or reset the phone as I want to retrieve the data on it, I tried the third and downloaded the mi pc suite, but the phone doesn't show on my pc, I receive the no device detected even after connecting my phone with USB

I have the same issue on my Mi Max 2!!!
And the developer mode isn't possible to enable, because of this black screen!
Please help!

I updated my Mi Note 4 system software yesterday to MIUI 9.6 (me thinks), but it is having booting issues. I struggled 2 hours last night to get it started but in the morning I noticed that the fingertip sensor isnt working. I cleared cache, added new finger print, still the problem persisted and then I read on the forum to power off and restart the phone. I clicked on power off and since then my phone is not rebooting. The screen in black, I can hear phone calls, msg notifications. I have tried pressing the power button for 40 seconds (as per the MI Support Tech's advice), followed by using the fastboot (power+volume down) and nothing happened, I tried the recovery mode (power + volume up). Still nothing is showing. The Mi logo and android restart option isn't showing only. The phone is black. I can see navigation light and the blue light blinking on the top left when msg/notification comes. I haven't taken a back up since many many months. I don't want to lose my data. Please help.

Why don't you throw your data in a PC or a memory card? Also guys if im not mistaken you can not rollback from MIUI 10 to an earlier version if you update via the OTA right?Or else your phoned will be bricked am i right? Someone confirm this cause its risky.

Solution for mi black screen.
Hello friends,
I think the issue in sensors, because when i bump my mobile on my hand the screen wake up suddenly but some time screen in hang position but when i try it one or more time its working normally .

Same issue
Hi, I recently updated to the 9.6.2.0 in my Mi note 4 and after reboot it started to go off and on (only the backlight (touch layer worked)). I rebooted several times and get it going. after few minutes went black again and after reboot the fingerprint sensor stopped working (HW diagnostics saying error if you try to test it) and then the battery status started act weir. If i plug phone to charger, no matter how many % i ve got it charge only 1% (after hour or so)and if i unplug it lose 5% in 5 seconds and stays there for amount of time till the battery reach the same percentage as the indication is sayin.
TBH pretty weird and pretty annoying.
And yes it is probably sensor ( or a driver? ) because turning phone up-side down or covering the proximity sensor osometimes help.
I dont want to wipe my phone until it is necessary.
Is it because of update?
Thank you

Hard to say.
Could also be a hardware issue.
I recommend to flash back stock ROM with stock kernel.
Maybe you have to wipe data (do factory reset).
Then check again.
Good luck !

You've already done the extreme of reinstalling a stock ROM and performing a factory reset. I'm also assuming you didn't install a bunch of apps before the problem started, though.
My advice would be: go back to stock ROM again, factory reset, and SLOWLY reinstall your apps. This will help narrow down what app could be causing your issue. (if it is an app)
No bumping threads after 54 minutes. Not cool. People here aren't at your beck & call :-/

sorry for that ,but this site is my only hope
i tried ..i put the stock rom without any apps installed.but i had the same problems..by example when i want to delete a widget from the screen the phone stucks a few seconds,and the came to normal..the home button had the same delay and the proximity sensor works with the same delay,when i want to close a call ,stays a 5-10 seconds to light up the screen..i dont know,what is with him,i m disperate
..and what is strange,by example when is on charge ,the home delay dissapeared,works normally,but the rest of the problems remain
comeone..nobody knows anything about my problems with phone?
1.send it to Samsung for warranty.
2.get your money back from "friend".
I think i had similar problems with you previously, even worse maybe. Battery shows charging while cable is unplugged. Some of the time it pops up a warning message "Unstable Voltage". I did the same thing as you, flashing roms, wiping x " i forgot how many times", factory resetting X times and so on. What solved the problem for me was ;
-> i took out the battery
-> left phone untouched for several days
-> put the battery back -> charged till full
-> wipe data, factory reset, wipe battery stats, wipe cache,dalvik as well, FIX permissions
-> flash latest stock rom ( 4.0.4 at that time )
-> reboot phone
-> root again ( flashing stock rom loses root ) using CF-Root
-> reboot to CWM recovery
-> wipe data, factory reset, wipe cache,dalvik as well, FIX permissions
-> flash PA (Paranoidandroid ROM - please follow the instruction from OP post) via CWM
->wipe data, factory reset, wipe cache, FIX permissions
-> reboot phone
-> wait for apps updated and then reboot to recovery and FIX permission for the final time and VOILA!!
The phone works great up till this moment. Not sure if you gonna solve your issue with the way i did it but might worth the try. Nothing to lose anyway it seems as you were hardcore-ing flashing roms and wiping data and such. Good Luck!
Certainly that i hope this will be able to relieve you of the unnecessary distress.

UP
Your friend clearly sold you a dodgy phone. You should demand your money back and use the phone to beat him until he pays. That is my diagnosis and clearly the answer to your "problem".
today after wipe everything and flash de jelly bam rom ,custom kernel etc..doesnt work at all,but i removed the battery for 30 minutes,and when i put it back and openned it ,everything works very well..just a calibrate,and clearly now have no problems..how long it mentain,i dont know,but even now i dont know what it had .. mistery
so,what are you thinking,what is the cause?

Hello ppl i could really use your help.
About a few weaks ago i installed a nightly version of cm 10.2 all was working fine until my phone didnt wake up at some point. So i tried to reboot phone with holding down power button until the 3 buttons start flashing but it didnt work out my phone didnt reboot. So i tried to do it again with holding down power button but now the 3 buttons didnt start flashing but the power led went of for a second and came back up so i waited after that. my phones screen stayed black for like 15 minutes and after that the htc quitly brilliant screen comes up. When i wait another 15 minutes it will start to boot into cm.
Now i get the following problems: Sound on my phone doesnt work anymore, Camera doenst work, Cant play videos, Gps doesnt work etc etc.
I tried to install stable version of cm 10.1 flashed new boot.img but didnt seem to solve the problem same problems as with 10.2 remain.
does anyone know how i can fix this?
Still didnt fix my problems does anyone know what to do?
Tried different roms with different kernels but booting still takes awfull long.

Maybe i must try format the /boot partition first? and flash kernel after that?
Because i think my problem is a kernel problem...

[Q] It keeps rebooting

Im Argentinean first of all and I'd bought my new GS2 3 days ago on mercadolibre.com.ar (a site like ebay.com) to a guy that imports it from factory. After of almost 50 days of waiting, i did got my new mobile phone, when i got it i'd upgraded to JellyBean with the official samsung rom, and that's when the problems showed up, the top left corner come overheat turning off the device, over and over again. So after some failed testing I'd chosed to change the kernel to Siyah expecting some performance improve but it become kind of worst because when the screen blackout the device just reboot itself, but if i keep doing something on it nothing happens, just when the screen comes black.
So i guessed that it may was related to the kernel, so downloaded another official rom jelly bean, this one was a Pre-Release rom, that some time ago i'd installed on a friend's galaxy s2 and it worked fine (despite the increased battery drain). This wasn't any solution though, because it keeps rebooting when the screen comes black.
I did tested to turning on without the simcard and microsd card, with the same results.
Another fact is that if i left the music playing and turn of the screen with the power button, nothing happens, it works perfectly.
It seems that is some kind of trigger when the mobile actually suspend itself doing really nothing.
Now i dont know what to do, should i test some custome rom/kernel?? should i get the chances to use the warranty? (implies to send again the device to china i guess ¬¬)
Please help, and thanks in advance.

You should try custom rom. Try to Flash Neatrom or any stock custom rom.
Hope it solves your problem.

Firstly, you need to verify that it's a genuine S2. Turn the phone off, take the battery out and post on here EXACTLY what you see on the sticker in the battery compartment.... Just don't post the IMEI number...

Because your phone is now in Bootloop.
Bootloops can occur pretty easily, it’s mainly caused because system files interfering with each other which causes instability and/or crashes at the boot sequence.
Think of system apps that are compiled incorrectly, permissions that are not set correctly, files from other devices and even an init.d script, everything is possible.
To find the cause of a bootloop you have to think about what you did before getting the bootloop.
Choose one of the following reasons that caused the bootloop for you and try out its solution.
– After flashing a new rom
If you flash a new (base)rom on your device it may not automatically wipe your dalvik-cache, This means your old dalvik-cache will be used for the new system files which would result in a bootloop, to fix this problem:
1. Start your phone in CWM Recovery
2. Go to Advanced
3. Choose “Wipe dalvik-cache”
4. Now go to “Mounts & Storage”
5. Choose “Wipe /cache”
6. Reboot your phone
Note: by wiping “/cache” and “dalvik-cache” you make sure it’s completely deleted, some roms use /data and some use /cache for the dalvik-cache
If the problems still exists after doing that, you could try to wipe your /data partition. before you do that first make a backup of your phone (in it’s current bootlooping state)
1. Start your phone in CWM Recovery
2. Now go to “Backup & Restore”
3. Choose “backup” (it may also be called “backup to internal/external sdcard)
When that’s done you are free to wipe /data, you can achieve this by doing:
1. Now go to “Mounts & Storage”
2. Choose “Wipe /data”
3. Choose “Wipe /cache”
4. Reboot your phone
If the rom still doesn’t boot correctly it’s probably the rom which isn’t working, contact the rom creator then and try an other rom for the meanwhile.

No is not, the cellphone starts normal, and while im using it nothing wear happens, but when i left it the screen goes black and the device reboot itselfs. But now im seeing that doesnt happen anymore, i dont know why.
Still with cyanogenmod rom, i connected the phone to charge the battery, and i saw a tendency of reboots and turnings off while the percentaje comes to 100% and a increasing overheat on the left-top of the phone, i suspect that the problem may be related with the amount of charge from battery and the overheating... Hardware problem?
Well... After all this time my cellphone went through the argentinean official service of samsung and the tech guy told me that he couldn't do anything on my device because he tried installing a lot of samsung official roms and the device was still malfunctioning. So he gave up on it, so i'd tooked it to another service (non official this time) and that guy told me that it may be a non official device, so he wouldnt do nothing on it, because i couldnt get the hardware that possible was malfunctioning. So here im now, with the all money spent for nothing.
My question is, what can i do to know if is or isnt an ORIGINAL samsung device? Knowing that i'll choose how to proceed. Txs!

RN3P Kenzo - Lot of random reboots and app crashes - possible a hardware problem

Hello!
I recently bought a Snapdragon Redmi (kenzo), it came with a chinese version of MIUI and on the first setup it already started to show some problems: when I try to connect to my google account it suddently rebooted. After some tries and reboots and worked but on day by day usage I continue to have random reboots and apps crashing.
I already updated to other miui versions, CM13, CM14 and some others roms and kernels, flashed with diferent TWRP versions, in all of them I got the same problem.
I think it's also not related to hard usage, because the problem appear when I open what's app, facebook, a lot of times with swiftkey. And I can open some heavy games without problems.
Also, sometimes it reboot and get stuck on a bootloop, when this happen, a backup restore or dirty flash wont solve the bootloop and I always need to go on TWRP, do a factory reset and flash the rom again.
I think the explain it's a hardware defect...
There are any other thing I can try to solve it?
Try flashing fastboot ROM if you didnt yet

I already tried once with miui, but I can try again with other ROM. Which one do you sugest?
You can only flash MIUI fastboot ROM via MiFlash, not possible to flash other...it must be a hw problem if you encounter that on every ROM...
Try flashing the developer ROM. Or look for similar issues on MiUi forum. Those guys will surely help you out!
Hit Thanks if I Helped You!

thanks pituca292,
i thing that would be no option for me,
i bought the device abroad, would be not economic for me to return it.
very strange what happening to my device.
reboots stopped (have no idea of what reason : recharge again from 5% battery, get into test mode (push 3 button for 10 sec': vol+, vol-, power).
but now other issue showed up : very lots of screen glitches, can use the phone like this, like some bad soldering inside.
first time i got into test mode, there were also screen glitches,
but now, whenever i get into test mode, downloading mode or the 3rd mode (with phone and cable picture), there is not glitchs at all,.
but after phone is starting - lots of screen glitches !!
i am lost

Samsung S7 shuts down

Hello, I have a Samsung S7. It boots up fine, you go into APP's or messages, pictures, but after 10 or 15 seconds it reboots or and or, it never operates normally. I would like to know if there is a way to fix the phone. Or if there is a way I can get all the information off the phone. Pictures and text messages.
I can't believe no one out there has had this problem. Can it be a battery problem? Can I load old firmware with ODIN? Any help would be great.

If you're unrooted , it's really strange to witness such an issue . Backup your stuff including the internal storage and then boot into recovery using the Vol UP + Home + Power button together . Scroll down to wipe data/reset . AFter it's complete .. reboot .
WARNING : This will wipe your phone completely including the internal storage . SO backup
If the above solution still doesn't work - FInd the latest firmware for your device from sammobile.com/firmware and flash it through odin
All set. Loaded the latest firmware this morning and I am all set.
