Tablet bubble (aka battery bloating) issue
When you see a bubble in your tablet screen, it can be
1) A new tablet that got an air bubble during the shipment
Fix 1: Rub your tablet to remove the bubble
Fix 2: Slightly bend the tablet to remove the bubble
2) Battery bloating issue.
If the bubble happened after months of use, it can be the battery bloating issue. We have the new feature called "Smart Charge" [Setting - App - MISC] which keeps the battery level between 55%~65%.
But if the tablet battery was bloated before, the bubble may remain in the screen or even get bigger.
