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 http://www.cartft.com/catalog/il/477 I've contacted vendor, and It's not for sale anymore (under this brand at least). Regards
