My mum's tab s2 is just over a year old and has started a reboot loop since September. I clear the hidden cache and it will be okay for a couple of days but the n it plays starts rebooting again. When it reboots the battery power can suddenly drop from 25% to 3% in a second. Does anyone have any other suggestions as I don't think it is right that I should be having to do this all the time. Also I'm concerned that it might be battery issue. Thank you.
Everything up to date but haven't tried in safe mode. It seems to happen once a week and after I clear the cached data it's okay for a week. I was just concerned it was battery as she has poor vision and has it very bright. Will try safe mode next. Thank you for replying.
Just wanted to update incase anyone else suffers with reboot loop. It turns out that my Mum was turning off the tab 2 every time she had finished with it. I asked her to stop shutting it down every time and guess what reboot loop has stopped.
