The last few days I found my android phone often restarted itself. There is no wind, no rain, why does it suddenly restart itself. Maybe because my cellphone is old enough, it's been four years. I was made quite anxious because the cellphone was included as a favorite cellphone even though its main function has been replaced by Asus Zenfone Selfie. I only use Posel only to send messages, make calls and receive calls. I finally went to search to find a solution to this problem.
