Screen randomly stays blank after hitting power button N900 - Sprint Samsung Galaxy Note 3

I've got a strange problem with my Sprint Galaxy Note 3.
What's happening is that randomly when I hit the power to turn the screen back on, it will do nothing then the screen will stay blank. The phone clearly still works because if I'm on a call or listening to music it will still keep playing and the volume and other buttons continue to work.
When that happens I hold down the power to turn the phone off and then on and it boots up normally.
Rarely what will happen is the same behavior except the screen will go strangely green after I hit the power button, making the phone unusable until an off/on.
This happens sometimes multiple times a day, sometimes days without happening.
Phone is rooted, running OC5 on Android 5.0. Problem has been happening for months. Haven't made any system upgrades or installed any major apps so that isn't it. I'm thinking it is some kind of loose pin/wire but don't want to crack the phone open without a plan.
Any help appreciated!

[Q] Broke Wifi and fails to power off

Hi, I have a 2 week old handset which has now twice displayed a pretty strange/annoying bug.
I have been using no Stamina settings other than location based WiFi and queue background data for the most part to gauge battery life under my normal work schedule but I noticed last week that my saved WiFi at home wasn't on, so instinctively I tried to click the WiFi symbol but to no avail.
I then tried to restart the phone, but when pressing the power off option, it simply booted me back on to the screen I was on before hand. This continually happened until I got pee'd off and repaired it.
Again today I ran into the exact same problem. No WiFi and I could not power off. After several attempts at powering off I managed to get it to boot into safe mode where I started uninstalling apps to rule out any rogue apps. I still couldn't reboot forcing me to repair and wipe the phone.
I keep telling myself that this is merely a software bug and I can't seem to find other posts where people are suffering similar problems.
So I futilely ask, has anyone ever had anything similar happen to theirs?.
Yeah I think this is a software bug too, a similar thing has happened to me a couple of times with the wifi becoming "stuck" and rebooting the phone fixed it but if you're having trouble shutting down your phone, have you got quickboot enabled? Regardless of that though, you do have two options to force a restart, either hold volume up and power, this will force shutdown or press the small red button next to the sim card tray.

I am pretty sure it is the quick boot option now. Stupid bug.
Phew...don't have to return it now.
I think sony have disabled the quick boot functionality for some reason, I ticked it thinking it might be almost like a reboot instead of power off & then power on, later I noticed the power off menu wasn't doing anything when tapping it, was almost about to do a reset but then remembered I ticked the quick boot option.
Hope they enable it in future updates.

Screen turning black and won't respond

after exchanging my phone due to the reboot problem, im encountering a new problem
my screen sometimes turns on by itself, and if i try to operate it at that point, the screen will turn black and nothing is functional except for the soft buttons and the pull down menu, only restart will solve this
sometimes it will also just crash to black even without the screen turning on by itself scenario
does anyone have the same issue? i suspect this is a software problem
I just got the z5 last night, and experienced the same problem this morning. Turns out that if you give the power button a 'double click', the screen comes back on. So this solves the problem reported above.
HOWEVER, there must be a setting (I hope) which we can change, I find it very irritating that as soon as I make a call, the screen goes blank, and you have to double-click the power button to see what is happening. If anyone knows about such a setting, please let us know!
My screen went black about an hour ago.
After Hotspotting for 40ish minutes so I could use my iPhone on the way to work on the train, I tried to check this forum with my Z5C, the back of it was really hot & after a few minutes, the screen went black & the phone was unresponsive for around 20 seconds & then basically unusable once it came back on, for another 20ish seconds, due to lag.

Did you ever find a resolution for this? it is driving me crazy, I've tried factory resets, software repairs via the Sony Companion and this still occurs, sometimes it won't happen for a week then sometimes it happens multiple times in a row even straight after a reboot. The fix that RohitMayor describes does not work on my device. This phone is really terrible compared to the Z3 Compact
I have the same issue. This pb occurs since i have update my phone to 6.0.1...
Any solution ?

Samsung galaxy s6 edge is in a weird type of bootloop freezing cycle

https://vimeo.com/194087533 link to video showing what's happening
So my sister's samsung galaxy s6 edge is in a weird type of bootloop freezing cycle, where it won't actually turn on but it can be restarted over and over again using the buttons.
A few days ago it restarted itself and froze a few times so she used the volume up and power key to restart it and it worked so she turned it off and left it for for a few hours and it worked again until yesterday.
Yesterday it started freezing again but the volume up and power keys no longer worked for restarting so she started to use volume down and power keys and by holding them in it restarted the phone. The phone would only stay on for a few seconds and then freeze again and she would have to restart it again.
Now it's got to the point where it won't even turn on and every time it's restarted it gets stuck on the Samsung opening screen like I've shown in the video.
I know the option here is to hard reset it but she has alot of videos and photos with sentimental value, so if there's a way to back it up before hard resetting it id love it know
Can anyone offer up a solution or 6 please? Appreciate it!

First thing... what model is i? G925? After i have this i can give you the best steps to take.
Its stuck in a bootloop and the easy fix is to boot to recovery and wipe data/cache then if not fixed flash the stock fimware. But there is a way to save the data. But i need the model.
And btw volume up and power does nothing. It will of just restarted due to holding power. Vol down and power is the correct way to boot to safe mode

[HELP]Xiaomi Redmi Note 4X stuck at blank screen.

I have a Xiaomi Redmi Note 4X, which I started using around March. Lately, I have been facing an issue which has left me troubled a lot. My Note 4X seems to be in a bootloop.
Around two weeks ago, I was casually using my phone in college. I had put around 25 apps on download from Google playstore. Alongside, whatsapp was running. I usually take pics of my lectures, so when the teacher had written on the board, and was about to erase, I quickly attempted to go to the home screen, by clicking the home button ( middle button), so I could launch the camera app, and take the pic. But, the phone didn't go to the home screen, and stayed at the app being used. However clicking on the recent apps (the left button), the two running apps showed. However, as I didn't have much time, I did what came in my mind. Reboot the phone. Unfortunately, as soon as it booted back, the screen remained black.
Its been like this for two weeks now. Whenever I turn it on, It will show the Mi logo, then the Android logo simultaneously below it ( Like usual when it boots), but after that, the screen goes black. Touching the three buttons at the bottom of the phone make the back-lit underneath light up along with a vibration(Like usual). Clicking the touchscreen gives a vibration. If a sim card is put inside, and a call made to the inserted sim card's phone number, the phone starts ringing as usual, however, still with a black screen. Another major issue I experience other than the black screen, is that the top right of the phone becomes really really hot as time progresses( within minutes)(This never happened before), and the battery drains really fast too. I get freaked out because of this( I think it might explode or catch fire), so I quickly turn off the device, after some tinkering.
I have been trying to find a solution since the past two weeks. Hard pressing the Volume Up+ Start button takes me into MiRecovery 3.0, which offers 3 options, 1.Reboot, 2. Wipe Data, 3. Connect To MiSuite. Going into 2 gives the option " Wipe All data" only, and 3 is seemingly useless the MiSuite doesn't support new versions of Android. Hard pressing the Volume Down+Start button takes me to FastBoot. It should be noted, that in both MiRecovery 3.0, and Fastboot, the phone doesn't warm up really fast, as it does when booted normally, and rather remains cool even if left for quite sometime in these modes (approx 30 minutes atleast).
The main thing I'm trying to achieve is to backup the data on my phone, mainly the photos (lecture notes), and whatsapp data. The rest of the app-data isn't that much important, albeit if also savable, it would be a bonus.
I haven't tried flashing any ROMs, recovery, or anything else, as I'm afraid the data may be erased, and as I have never done anything like this before. Also, my phone isn't rooted, as I didn't feel the need for it to be.
Help is highly appreciated. I hope to be able to safely extract my data, and be able to start using my phone again.
Thanks to advance to all those who reply.
Guys?
