[Q] My Kocaso MID M762 android tablet screen is black - General Questions and Answers

Okay, so I just got my new Kocaso MID M762 tablet today. I turned it on, installed Kik Messenger, Google Chrome, and 4Shared. Then, I noticed that my screen was getting kind of fuzzy and the light was fading. Before I knew it, then screen went completely black. Here's the weird part though. I can put a flashlight right up to the screen and I'll be able to see it. So I used this and went to check my brightness setting, and it was all the way up and not at 0. So I am at a loss as to what to do now. I should also mention that I've tried resetting it, and that has not worked either. What can I do to fix this, or do I have to send it back?

Fuze screen problems

Today I used the iGo8 GPS for a little bit just to get onto the freeway. The phone tends to go to sleep, and when that happens, it loses it's GPS signal. Since I was already on the freeway, I know my way around so I just let my phone sleep.
When I got home, I realized the bottom part of the screen, where you can scroll through home, people, messages, etc. is messed up. That part of the screen keeps flashing. AND the GPS screen got burnt into the screen, like how things burn into Plasma Screen TVs when you leave it there for a long time. But it's not a completely burn on, it is like a ghost affect.
I have soft resetted my phone. Doesn't work.
Anyone knows how to fix this problem?
Thanks.
I can post pictures/video if it will help.
Have you tried running igo again and closing it down properly?
Yeah, I closed igo properly. It's not just burnt in the igo screen new. It changes. Now it's the Today page. I can see the "Phone" and "Camera" buttons burnt into the lower part of the screen.
ROM Issue?
What ROM are you using? I always use EnergyROM and its a great ROM but it always does the same thing... i thought my phone was ruined the first time i saw this, but when i flashed to another ROM it all went away, im not sure if certain ROMs use different video drivers or what, but my problem atleast seems to just be with the ROM.
Good Luck!
use a all-black or all-white image(i think all black is betteR) and keep it on to try to reduce the burn it...
ohhh. I am using EnergyRom as well. I will change roms and see what's up.
the all black image seems to be a good idea.

System Unresponsive with 5.1 Stock Rooted

Anyone having the same issue and have found a solution?
Phone suddenly stuck at some instances even with non-extensive usage.
Yesterday I was only using Facebook app. When messenger bubble pop up, my phone suddenly spiked. Moved once and then it got stuck already. You'll notice that it's not Facebook app only that's not functioning since nav. buttons are also stuck. You can't go press home and clear recent apps/hibernate apps. Power and volume buttons are also not functional.
So I assume the main system crashed. I only did a long press on power button to restart.
I installed Franco kernel r73, and thought that issue would only occur with stock kernel.
However, it occurred again today, I was viewing photos in Stock Photos app. I haven't started viewing the first 10 images yet, so memory should not be consuming that much. I turned on the auto rotate to view the image larger. When I turned the phone landscape, it reacted like it's about to rotate. And suddenly it got stuck. This time, power button is functional. It turns the screen on and off but it still turns to the same stuck screen, not the lock screen.
I've been experiencing this since 5.0.1. and almost everyday since I updated to 5.1.
I'm not sure if this is a hardware issue on my unit since mine is already about 1 year and a half old. I don't want to buy another phone yet!
Or is this a common issue nowadays due to Lollipop upgrade. If so, then could you provide temporary fix before they update this on 5.1.1.
Thanks a lot!
I had something similar . When I put forward the curtain hangs notice and then everything worked fine
Meh
I've seen this behavior on my Nexus 5 only on 5.1, and I'm pretty sure, it was introduced with that specific lollibug version. It's really annoying, that you have to reboot the phone every two or three days to avoid the freezes.
There's already in issue for that, it has got the ID 161032.

"Ghosts" on the display

Hello everyone, this evening when I play with my s8 plus, i notice that when i swipe from one screen to another, there are "ghosts" goes from top and bottom of the device. The worst it is, when the bringhtness is set to center/low and bluelight sensor is on, ist that normal? I try to make a video and take the screen when I took the password. Phone is after latest update QDD, after I install it, i clear dalvik cache, after that I make factory reset. The phone after the update is little bit slower, and how i remember, befor update the antutu was showing acros 175000, now it is about 172-3000. Where can be problem?
The new video and photo what i take:

I see nothing on the pic and vid.
What ghosts?
Could you please draw in the picture and Mark the places with the ghosting?
Hello, yesterday I was in Samsung Service center, and they told me, that is normal display functionality. So I was going to the near shop and compare it to another galaxy S8+ and lets see the differences, my display is little bit purple, what i should do, they said I should wait to another update, but last update QDD im currently download and install it and the phone have still a little bit purple colors on some angles. PS: my phone is after QDD update more lagging than before, some ideas what I should do? I made Clear dalvik cache and after that factory reset.
If you are unhappy with a device costing 1k€ then take it back, I certainly would. I am not suggesting you have a lemon but let the retailer see the problem and if you are not satisfied insist on a new mobile. Mine, so far, is fine, zero problems (touch wood). If it misbehaves it will go back as it should.
Let us know how you get on.

Use the red green blue test under *#0*# and check if your problem exists there

I would suggest getting it replaced. However, if you have as much trouble showing them what the issue is as you are us, I doubt they'll swap it. You need to put up some solid color backgrounds and see what it does. The pics you're posting could just be banding in the original image. Not sure what to to tell you.
That's the problem when I try the service code and turn on the red, green, blue screen, everything looks OK. As soon as I go to the main screen or I go to the application menu, and the brightness is set to less than half, the problem is there. This is not a static picture, the "bubble" above moves. When I turn on the blue light sensor, so it's even worse, but if I give more brightness, the problem is not. Also, there is no problem in any application. It would be good to have someone who has s8 plus orchid gray, to check if have the same problem, or at least try setting the orchid gray theme. Anyway, when I compared it with the other s8, the display was more pink, and I did not notice the problem what I have.

Believe me. I cant swe any hosting.
What I see is a dark screen where it should be dark.
I have orchid grey and I can check something for you.
PS. I checked every single picture posted here.
BTW. On yt video the animations are very slow. It looks like you turn on the specific option on the developers setting.

Maybe it is just software, we should wait. But at the night it is really annoying.

Screen and graphics are just jumping, flickering and doing random things

My Samsung Galaxy S5 Sprint (carrier unlocked) with Android 6.0.1 has suddenly been acting weird. The screen and graphics are flickering and jumping about the LCD screen. Once it even turned the screen negative with black and orange colors. I manually went to accessibility settings and enabled negative colors so that the screen went to normal.…That is until it again went negative and I had to turn off negative colors afterward. I don't know what is causing this and I want to badly fix it.
Specifications:
Android Version: 6.0.1 from Lollipop
Rooted: Yes (probably since it had SuperSU already installed when I got it)
Now I haven't Factory Reset it yet because I fear that resetting it to factory default while it is rooted might break it. I don't know how to unroot it either. I will be helpful knowing if I can safely reset it with it still rooted.
Edit: I also want to say that whenever I try to share my PC internet connection to the phone, the phone somehow manages to crash my PC every time. I can find no fix for any of these problems. I am so helpless and hopeless…

Screen Color Balance/Blue Light Filter

Hello,
First post here, looking for some help.
I just updated my At&T Galaxy Note 8 to Oreo, and with Oreo has come a very strange problem where the color of the screen is very red. It is definitely a software problem, as the correct color balance is there for a couple seconds after booting, then the red comes back. This has lead me to believe it is a problem with the blue light filter being unable to be turned off. The switch is settings is definitely off, and I even tried using Adhell 2 to completely disable it, but have had no luck. I've also revoked the permission to use screen overlays of all my apps that had it and that didn't help either.
If anyone has any ideas how to get my whites back to being white, I'd appreciate it greatly!
I'm having the same problem. Also my notifications aren't showing on any of my apps until I open them. I read something about the blue light application being turned off. I made sure my location is turned on and blue light still is stuck on.

i am having the exact same problem as well. same situation just i have a tmobil phone. i tried to disable the blue light filter with the bk manager to no luck .
my wife who has a note 8 as well has not updated and when compared side by side my phone has the blue light filter stuck on with the minimum opacity. i can still turn on the filter it just makes it even more incredibly red. i sadly do not have any advice to offer and hope there will be a hot fix soon.
To all who are suffering this. Check these settings.
1. Go to Settings/ Device Maintenance/ battery and make sure power saving mode is turned off.
2. Settings/ Display/ Screen Mode and make sure its on the highest setting.
3. This is mostly a diagnostic step but, Turn the blue light filter off, then HOLD the power but to open the power menu then touch AND HOLD power off till it asks for comfirmation to boot into safe mode. Then do it.
If non of that works. A Factory Reset may be needed.
Back your personal stuff up. NEVER back up settings if your having a software issue.
Id turn the blue light filter off first then reset from recovery.
Mine started doing the same thing today and I checked the setting and saw I accidentally turned on scheduling.
First note 8 I bought did this the first day, ended up returning g it for a new phone. Mine had a yellow tint to the screen and there's a million things on Google about it.
