First of all - Hi!

I am big fan of this forum - but this is my first post

I have my Onda more than 1 year and now I have big problem :-/

First problem was with touch screen (ghost touch)

And after some time on top of touch screen problem one additional appeared:

After some time after full boot - screen blinking. Below you can find movie of my tablet:

I tried to write to Onda support - but no response :-/

My version is: v2.

Changing version of fw problem is still the same..

Please advice something!

Thank you for your support!!

I think yours is a hardware issue rather than firmware issue maybe cable loose or driver IC has come to the end of its useful life.

NOTE :

I dont know if this can help you but it is a very rare Android application to recalibrate Capacitive touch screen, I have been using this app since 2011.

You should try to recalibrate it a few times if your touch is lagging. But after it is OK dont use it anymore maybe once every 6 months only.

Please also check your internal cable, BUT be very careful when taking the back cover apart as it might cause more problems (e.g more broken cables! and missing buttons.)

Thank you very much for your response!

I think I have found a problem - I hope this will help someone with the same problem.

I noticed (tablet was in a drawer) that one of battery just exploded!!

When I disconnected damaged battery - tablet works good (but even with a power connected battery losing %)

Now I need to find a battery replacement!

If you have additional ideas - please let me know!!

Search AliExpress site for replacement battery, I have some good experience buying thro AliExpress (as with any online purchase , do your background check first) I have no complains so far on any traders I have dealt with so far except for one who wanted to con me out of my money but a quick report to AliExpress (got a refund and the trader was banned) : try this pages as a start : http://www.aliexpress.com/af/Tablet-Replacement-Battery.html?ltype=wholesale&SearchText=Tablet+Replacement+Battery&d=y&initiative_id=SB_20150301202941&origin=n&isViewCP=y&catId=0

Or the best is this site : http://www.actablet.com/replacement-12000mah-battery-for-onda-v972-quad-core-a31-tablet-pc_p5327.html

But while waiting for your battery to arrive it is bset to check and replace the "Power IC for battery charging" as it could/most probably/might have "KOed" during the battery explosion causing the IC not to charge the battery. that I am very sure of.

GOOD LUCK!
