My phone. (Galaxy A10) keeps automaticaly going dark and back into hibernation/sleep mode as soon as i press the power key and have entered my pin no to unlock the Homescreen. Sometimes this happens a few times in succsession and i have to keep pressing the power key and re-enter my pin no to unlock the Homescreen. ( Very Annoying!!!!!) As far as i know and i have checked, It is not in either power saving or battery saving mode so i dont know why it keeps doing this. I dont want to resort to having to go back to Factory Settings. Any advice would be greatly apprieciated.
