Hi. I updated the latest software (see image) and since then my phone had been buggy. Biggest irritant is when O unlock my phone it locks itself again almost every time. I also have issues with the Edge Lighting but that I can live without at this point.
Sometimes a sd card can cause issues so please remove it just incase.
What i advise to do if a phone is misbehaving after an update is …
1. Please put the phone in Safe Mode which disables your downloaded app's but let's your stock app's keep working. If the issues stop then this highlights a downloaded app as the possible issue. Come out of Safe Mode and start deleting your most recent downloaded app's one at a time until it stops.
2. Clear your phone's System Cache Files by turning your phone Off and then from a set series of button presses go into the phone's System Files and clear the cache. No information is lost this way.
3. Last resort is a factory reset after backing up and removing any relevant sd card.
