My phone is a LG Stylus2 Dual Android version 6.0.1 Android security patch level 2016-12-01 Kernel version 3.10.49 Build number MMB29M software version V10d-AME-XX. It was bought in the USA on March 2017 and brought to Brazil, so no warranty. The problem is sometimes the phone, correctly charged, shuts on a black screen, little red light flashing, and the only way to bring it back is to remove and put back the battery. Then it turns on correctly. This happens sometimes 3 times in the same day. Any clue? Thanks, Luis.
