Hello, I am new here and am absolutely not a developer.
My company has bought a year ago 1K tablets from a vendor in SZ.
The tablets have installed a developed application by a third party for elderly which requires that the tablet screen will be ON 24/7 and constantly on a charger. The application manages to adjust the screen brightness during the evening/night.
Now after 15 months we experience that tablets are coming back with a strange screen behavior.
Screen is ON constantly
Pressing shortly twice the ON/OFF button the screen goes OFF and returns ON with horizontal lines but the touch functionality in tact.
Turning OFF the screen (press ON/OFF button shortly once) for 20 seconds and then turn ON the screen again, these lines are gone.
When you repeat the first step turning OFF and ON the screen, the vertical (blurred) lines returning.
I have tried many things.
Flashing the firmware using flashtool in different settings (we have the firmware).
The factory can reproduce the issue, but is reluctant to find a proper solution.
I would like to be in touch with an engineer / developer who would be able to helps us out.
We can sent some tablets for examination or just the firmware files.
I am reaching out on this forum hoping on some positive response.
Thank you for reading,
Best Regards,
Jan

Hi guys...
I'm glad to post my thread in this great forum which was helpful since I've bought my new (Plaris - HTC Touch Cruise) ... " it is new (9 days) so far, lol".
okay, i wish you are doing well.
Alright, I searched over the Internet about (the blank screen) when I lock my device and most of the post are about doing a hard reset (and it worked for me many times) but the thing is I've my files and worried to loose them esp. the messages. So I've tried many and many times to lock and try to unlock my device............Guess what?!
I've found the solution and it is in here for you!
okay.. I installed the nice app. (vSnap) - Download - and it captured two amazing pictures, here they are:
1.

they show the accurate place where you can press and unlock your device easily.
first, try to click on the "unlock" on the left buttom of the device.
then, press the "unlock" on the right and middle of the screen.
I hope you like it and it helps you.

What exact problem were you having with your Polaris?
There's a great app called MyMobileR which will let you take screenshots of the screen, and also control the phone from you PC.
Also, if you're looking for an 'unlock/lock' application, I'd recommend S2U2 which can be found here on XDA with a simple search.
Hi peepz,
Since a week ago I installed ICS (9.2.1.11 WW) (android 4.0.3) First I was really excited about it but after 20 minutes I saw alot of bugs. So I started to look on the forum if more ppl had these but since I have alot of bugs I decided to make this post.
Bugs:
1: My screens give something like dead pixels (don't really know how to describe this so made screenshots and photo's of it) So on the photo's I see the dead pixels (as you can see too) but on the screenshots it shows like there are no problems?!?!!. So if anyone know how to fix this please tell me!
2: Sometimes my screen just turnsblack and I have to hit the powerbutton once for putting it in sleep and hit it again to wake it up... kinda weird? (i also goes to sleep when im playing a game or using a app, so it's not that im idle for too long)
3: When I shutdown my device with the power button and select shutdown. This all works but when I try to boot it up again I have to put the USB cable in my tablet and connect to the pc or the charger else it won't boot up!?
4: On some locations my wi-fi don't work it just keeps saying about getting ip adresses or something but that takes thousand years. (and my mobile does work there. I got nexus S running ICS 4.0.3 too).
So if someone could tell me how to fix one of these problems or maybe even all of them! That would be great!
Yours,
Kasper

Hello, I'm having issues with my Moto G 2015, the screen registers input when I'm not touching it, I switched on developer mode and set it to shot touches, and this was the result:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_toggle_sidebar": "Toggle sidebar"
}
It does this seemingly at random, and it almost makes it entirely unusable. I've tried wiping the cache and factory resetting the device, and it still has issues. I've also tried cleaning the charging port with a can of air, and cleaning the screen. I'm not using a screen protector.
Any insight would be appreciated.
Apologies for the size of the screenshot.

Did you look through some of the threads here, there are several threads similar to yours? Basically, many of us have the ghost touch issue... This has been on ongoing problem for many people since the device was released, and it seems to get worse and worse with each subsequent OS update (it is rumored that this is why the 6.0.1 roll-out seems to have stopped). There is no known "fix" unfortunately, although if you have a tempered glass screen protector, many users have reported improvements after removing it.
Wow I thought this happened only with me, I called it overdrive mode, happens more often when battery low, It once took 44 pics in like 5 seconds!

I've tried several keyboards that allow swiping and they all malfunction when I try to use them. They work some of the time, but very often the swipe trail will veer down to the space bar in the middle of each word. This happens on the stock Samsung keyboard, the Google keyboard, Swiftkey and Swype. I'm guessing it has to be a screen problem, but have no idea how to troubleshoot or fix it. It's out of warranty by about six months, but it's in perfect condition otherwise. Running rooted KitKat.
Any ideas?

You can check the touchscreen function in Factory Mode.
Use calculator to enter the code:
(+30012012732+
In Factory Mode, then enter
*#0*#
Your tablet will have a menu of many tests, including the touchscreen test. Use BACK button to exit testing and factory mode.
This is an example, if all are green, it will pass and exit the test

Thanks

Edit: Fixed by reflashing the ROM I'm using.
Restore the device to factory settings and your done!
Before that make back up anything you need!
Hi all - need answer from older members, googled a bit before no information regardless to my question what i want to know is it problem or not. Is it due f1.9 apertature or no ? Changing 4.3 - 16:9 modes , nothing changes, same effect. I can see it only in close range - 30cm range, like in these photos. Model is international unlocked, 920 android 7 BTU feb22 . Found this only now, by doing macro shots on the table ( have phone for 5 months, under warranty - thats why wanna to hear answers is it a problem, give them to fix it or no, its ok )
I'm receiving this "fish eye effect's" , very small amount of it, near corners - I marked RED or Black color with a line the real position of object in real life and what I get wia phone when I take a picture in 16mp mode or any other mode.
