Hi,

First apologies for delay.

Actually, I wished someone else will give you feedback earlier
since I don't have this screen anymore.

Anyway I know it worked well once applied to some 4.2 rc version.
(and also merged downstream in tizen on 3.14)

Doesn't the change look trivial ?
Do we assume it will work on later versions too ?

For the record here is the reference of the mentioned touchscreen :

MM500

I've contacted vendor, and It's not for sale anymore
(under this brand at least).

Regards
