Since a few days my Archos 101 G9 has got this problem.
I activate the device and want to unlock it.
It looks like something on the left side is touching the screen.
Tablet is active, but the back-'button' on the lower left hand is blinking like someone is tapping it.
Programs won't run, the back does really work.
After a few minutes the blinking stops and the tablet works as it should.
I tried cleaning the touchscreen (dry cloth), took a small peace of paper between the edges to remove any dirt there.
But still this problem occurs.
Updated and reset to factory yesterday.
Firmware : 4.0.28 (Android 4.0.4)
Board : A101S-V5
OMAP : OMAP4430 ES2.3
BOOT : Unkown / 5.05.000009 - C0x00
Smallband : Unknown
Build : IMM76D
Try to recalibrate touchscreen 10-15 times.
If it will not help - then you have to RMA your tablet, I think.
Hi guys.
i bought a mtk6577 clone s3. My problem is sometimes i rebooted phone, after opening proximity and light sensor doesn't work. screen don't turn off in call and doesn't call the person displayed on screen when i take ear. And battery drains too much. (example: when proximity and light sensor works with %90 battery, when it doesn't work after reboot plummets to %50)
Another issue is when i reboot phone, boot animation doesn't show when proximity and light sensors don't work.
I bought twice of the same phone and sold another one my friend. Same problem on it. I think this is software problem. I haven't any idea will i do.
My phone specs written below:
Model Number: A117_T_MULB
Android Version: 4.0.4
Baseband Version: MAUI.11AMD.W11.50.SP.V20,2012/10/25

Thanks for all your support. Sorry for bad English.
Anyone have idea?

small guide to repair damaged touch screen & Upgrade to rk 3188
last weekend i have replaced my touch screen display damaged, and upgrade my KGL dual core cpu to RK3188 quad core:
I order display replacement and slot CPU from my vendor (25+75$)
Tutorial
1. wait delivery from china ...
2. remove 4 screws behind the panel of unit
3 remove 4 screws to pull up the display,remove the little orange connection of toch screen, then remove 2 svcrews and tape to slot cpu.
4 pull up display and disassemble by removing scotch tape.
5 replace the new touch panel, be very careful don't touch the glass on the inside...
6 lock the display with new scotch tape, re connect little orange connection on the inside
7 assemble all...
for new cpu need to download new ROM with rk3188 firmware like this: http://forum.xda-developers.com/showpost.php?p=60591423&postcount=12068
put on sd card and flash it...
no need to flash new MCU (is the same)
enjoy

If you need parts for Joying Head units please PM me and I will try to help.
I need to know your exact model number or a link to it.
Mine is not a Joying head unit.
I need a digitizer for my KGL rk3066 unit, aka Naval 2. Any ideas where to order one from?
Thanks
Digitizer failing symptoms?
Yesterday and this morning my HU touchscreen failed to work on first boot. After rebooting (reset or acc off for 30 sec) it restarts and work fine.
I wonder if it is sign of failing digitizer? How yours have behaved? I want to be sure it is failing digitizer as I also updated MCU (KGL) to 2.83 posted here on XDA and touchscreen problem started after that.
I'll try to revert to old MCU version (2.80) but I will be thankful also for info on signs of failing digitizer (as I also installed the reverse camera and I have also clues that sometimes reversing line may introduce some ghost current into MCU so it may also coincide with touchscreen issues somehow).
Any help and experience sharing appreciated so I can pinpoint the source of issue not rushing to replace digitizer itself if it is not busted for sure.
At last!!
I'm not the only one.It happens the same with my unit.Mine is kgl4.
I tried many mcu's and malaisk roms,etc.

I think maybe you have a little problem of contact... try to open front panel and see the connection of digitizer...
in my case, the damaged digitizer create a problem at the top area of screen... in middle and bottom the screen always work fine...
dont think yours is a software problem...

Well, in meantime I again updated to v2.83 - from diff sorce - to repeat test. After few days - problem reappeared. With old version for almost month, cold weather etc, - no probs.
Just for anyone interested to know. I may be SW prob after all.

Many thanks for your tutorial!!
I have exactly the same problem with my unit, my dealer was Mekede but now they doesn´t answer me
Where i can buy a new display ¿? i have a MTCB KGL RK3066 unit with 7" inches
Thanks for your attention
hi. i use joying headfor ford focus /rk 3188 unit and status bar doesnt work properly. pls help me for buying new digitizer
You would think one of these guys would be smart enough to sell PARTS for these units like digitizers, LCD's, front control panels (when the buttons/knobs break), replacement CPU boards, bluetooth boards, etc... they would probably have a pretty good amount of sales.
They are leaving some money on the table they could be making with little effort.
I still looking for the digitizer without success....Does anyone know of any store that has them?

Hi, I have an i19100 with broken screen. Since I couldn't find a new LCD replacement in my country, I had to buy a second handed i9100 (with damaged board but working LCD).
So basically I replaced my board with the other one, now when I plugin the charger to my phone the battery icon appears and disappears in 1 second repeatedly, It's like flashing. I have no idea what to do since I wasted money on that...
On backside of both phones it says i9100 but the one with damaged board and LCD, it also says SSN: I9100-GSMH
Why the freak would Samsung make thousands of versions for a phone...
Can anyone help me?
Problem solved, there was a problem with android 7.
I had an extended battery and could get into download mode and downgrade it to android 4.
Then I pulled back the standard battery and it started to charge normally....
So confusing but yeah nothing is better than official roms
Hi all,
First post here! So I replaced the screen on my honor 10 lite the other day, as well as the charging/headphone jack pcb and battery - all working fine aside from now none of the sensors work. So accelerometer, gyro, screen brightness (auto option no longer there in phone brightness settings) and proximity are not working. I know underneath the main motherboard there's a 'sensor board' small pcb - does this handle the function of all the sensors? A new board looks inexpensive enough - i don't see how I could have possibly damaged the board but if replacing it will fix it that would be easy, just don't want to spend more money on repairing this phone if I don't need to.
Appreciate if anyone with any insight could help! Thanks!
