Icon’s title text mismatch

3 days back, when I unlocked my phone, I realised something off with icons and it’s display text. i tried opening some apps but I see blank screen. couldn’t restart the phone. only option I was left with, is to drain the battery and turn on again. i did and it was fine after restart. Took some to drain battery.

luckily, I’m sitting in my home. What if I’m in emergency situation.
