Is there any Android phone test center in your country? There are at least 3 major test centers here in Seoul. (1)SKT Open innovation test center (2)KT Econovation test center (3)U+ Open innovation test center Each test center offers various Android devices(of Samsung, LG, Pantech, etc..) without any charge for testing purpose. The Problem that i got is, most of devices from these test centers are domestic products(For South Korea). Sometimes major smartphone benders prepare two similar models (Domestic and International). And international model is also sometimes customized for each countries(i guess). So Same brand smartphone/tablet shows little difference in each countries. Easy way to fix issue from this kind of differences is visiting test center in targetted country. I'm sure there are many test centers all over the world. Are there any this kind of testing facilities in your countries? Then Please let me know.
