Hello Blackview team. I have just upgraded my Android to Marshmellow 6.0 yesterday at Blackview service center and then i upgraded it to the latest version. Everything works perfectly but i noticed my default language is Bahasa Malaysia. I changed to English (United States) but for some reason it keeps changing back to Bahasa Malaysia on its own. How to solve this problem?? I prefer using English as my default language. Pls reply A.S.A.P and help me.
