Just bought a (good) cheap Chinese phone.
JIAKE JK12 android 4..2.2 I have a big problem : the top and bottom of the screen is not callibrated.
Although all the center works fine but impossible to reach any point on the first and last line.
Tried to reset to factory did not help.
Any idea how to sort this out?
Many many thanks

A new Hyundai Rock X IPS tablet.
Loaded Android v4.1 stock Firmware.
Turned off at evening as always. Turned on next morning routinely but waked up without Touch function which makes the tablet unusable..
Reflashed several time w/ FWs of the last two version of factory.. Every time the same result. Booting up w/o touch facility and not possible to start and execute initial settings and use the tablet..
It is bricked some way..
As it is not recovered by flashing with factory FWs, what would be the reason? Hardware failure ? But screen is okay, only no response to touch.
What do you suggest ??
I am away to China and no chance to ask service and replacement..
But if it is screen hardware failure maybe a new screen (as spare part) may be purchased and replaced..
Do you think Hardware ? Could it be disconnection of some part such as digitizer ?
Unfortunately i just experienced the same problem. Searching on Google and it seems its becoming a common complaint. I think its a hardware problem.
P. S.
Mine is just 4 days old.
Hi, i have this chinese tablet from not more then 2 weeks. It was working perfectly till two days ago. Suddenly the touch screen is not working any more, the only way two make it functioning is with mouse. I have done the fabric reset, but still the problem persists. Anybody can suggest me any solution. I could not understand if it is hardware problem or not. I didn’t found anything similar on the net. The fabric firmware is 2.23.
Thanks in advance.
Hi everyone, hope you can help me beacause im at my witts end.
In the last year, my galaxy s2's screen has occasionally stopped responding, the os was still running and everything so it wasnt frozen, my touch screen just simply stopped working. Only way to fix it was to hit the back of the phone and do a battery reset. This issue started poping up more and more, and now it won't respond.
Some info you might want to know:
Model: GT-I9100M
Age:~2 1/2 years old
No custom roms/kernels have ever been installed, has always run off the stock.
Never been dropped or had water on it (I took very good care of it)
The nav bar at the bottom (back/search/options/menue) and hardware buttons all work. Everything above the screen no longer works.
What iv done:
Iv reset the phone, did a bettery pull for the night, fully charged it, looked at the board and checked all the connections (all good). Would flashing a custom rom/kernel be something to try next? I read in a forum that someone had a similar issue to me and did that, but it didnt help.
Has anyone had a similar issue with their touchscreen? Why would the bottom nav bar work but no the rest of the screen? Could it be locked somehow? If it is.. how would I unlock it?
Thanks alot guys..

Maybe somethin is lose, take it to a repair shop
Hi guys,
Device: Version is G9 101 TURBO 8GB (A101).
Issue: depending on how you hold the tablet, lots of ghost touchs appear on screen and cause undesired touches. Example: if I hold it on the left side and try to use Google Maps, maps get crazy and start moving all over and zooming in/out.
I see some people complaining about it, but it's still difficult to see if it's a hardware or software problem.
Some people say reverting back to firmware 3.2.80 fix the problem, but I tried to downgrade the firmware with official and rooted versions and been unsuccessful (official gives error 221 because you can't officially downgrade and the rooted one flashes Archos logo nonstop).
I also tried to install CyanogenMod but installation fails after I select the ZIP file (stops at creating data ext4). Maybe because it's not rooted (I only have SDE installed).
Others apparently sent it to Archos for repair but I haven't seen the results - did them fix the problem?
If you experienced this issue, could you please post your solution?
Thank you!

Just a follow up: I went back to the store and replaced for another one (same model) and this one works perfectly.
If it matters, the first one had serial number beginning with PR13 and the new one has PR08... maybe it helps someone.
I actually have the same problem. My A101 G9 got its LCD broken some time ago, I ordered a new display and replaced it myself (because Archos assistance was really awful, they sent me the tablet back with the transport costs added only) and now i had this strange issue in the bottom right corner. It's now impossible to use. I thik it's a digitizer glass issue, can you help me?
hmmm... I have no idea what might being happening there...
In my case I replaced the unit for another one and it's been working fine BUT after charging I noticed I might get ghost touchs in the corner too but in that case calibrating (inside Settings > Repair) fix the issue.
The unit I had before, nothing was fixing... so probably a hardware problem.

A while ago I found a Galaxy Mega in the trash when I was out with family and took it home. Upon further inspection I found that the inside panels of the touchscreen were broken and nothing was visible.
Forward to the end of last month and I finally got a replacement screen for it in the mail and gave the phone and the replacement screen to a friend of mine that works in fixing phones and such.
When he replaced the screen, he told me that the touch inputs worked fine, however, after I told him to factory reset it since I didn't want to go through the previous' owners information and the data was wiped, the screen didn't respond at all to touch. We have tried soft reset, updating and what not [with the help of a smartphone mouse] and we really don't know what to do since I can't get a refund for the screen -_-
Any help with this would be appreciated.
Have you tried Flashing the stock ROM?
