Samsung Galaxy S3 GT-I9300 Android 4.1.2 Baseband I9300XELK1 Kernel Version 3.0.31-764725 Build Number JZO54K.I9300XXELCC
NOT rooted
For the past couple of weeks this device has suddenly started to crash at least once a day
- While using an app it would freeze
- After no usage for some time, phone would go on standby and will refuse to wake up.
- Sometimes it would reboot by itself
Have to hold down power button and restart the device. What should I do? Thank you
