Good evening, I bought teclast f7 few months ago. It worked fine, until something happend and now it freezes out of the blue whenever it is plugged in charge. I have noticed that this is a common issue among the users of teclast f7. I have searched on the web and I have found several ways to solve the issue, however none of them worked for me. Since it is a widespread problem, Do anyone know the right way to solve the issue?
