 Hello, yesterday I began to have failures in my cell phone, notifications are not reaching me through my mobile network, but in wifi they arrive in a massive way, it is bothering me and I would like to know if anyone knows how to change from 7.2.2.0RU to Global, Since it has more updates and improvements ... I am not root and I have already done everything essential (reset, configuration, etc. Without solution)
