That sounds exactly like the problem I have with mine. Could you please share your touchsetting.gt f ...

Follow the zip file I am using for touch screen and stylus and Datasheets of GT928 and GT9110P (Hi12 Z8350 uses GT9110P) I have changed parameters 0x804A, 0x804B (these are for Y axis resolution lower and higher bytes - that was wrong); 0x8053 and 0x8054 for Level to detect touch on the screen; 0x8075 for Level to detect driving stylus on the screen (moving it after it detected) and 0x8076 for level to detect the stylus on the screen.

Update: I could not attach the datasheets here (max 1MB). Search in Google for datasheet of GT928 and GT9110

Could you try it and give a return if it works for you ?

Thanks !

Could you upload a video with the issue (maybe a point I did not try to) ? I sent a PM to you !

How is your touch working, now ? Better, worst, same thing ?


I think explain HERE how to change parameters will be not good and usefull! This could cause confusion and problems for non technical users (just to give an ideia: trying to change one value, I miss calculate the checksum and when restart Windows (to validate the new configs), touch was in false detection all the time on the Start Menu button .... until I can open windows explorer and remove the touchsetting.gt, it consumes some battery, processor and my patience !! )

I just saw someone complaining about this problem in the Hi13. For me, I got this problem once, with charged plugged in, stylus was not working very well !

Just to clarify: Are you using my file or from other post ?

You're welcome !
