I too faced similar issue while working on construction site. Kindly let us know OP8 have bomb inside, it will blast after heat?
Because the app is using more resources than it normally does. Force stop the app. Report the bug.
This happens when your phone gets heated up to a certain temperature and when you exceeds those temperature limits your phone will automatically switch off to prevent something bad happening try using your phone in a cool environment do not use your phone to full brightness for more than a 5-10 mins in direct sunlight keep your recent apps clear
