hang problem

at any specific app
or during multi tasking

please sir give me some suggestions

first go to developer option and disable this option and then observe

and one more thing that
did you download any apps or game recently?

If the freezes and lags are due to minor firmware problem or glitch, then this procedure is more than enough to fix them.

Press and hold the Volume Down button and don’t release it yet.
While holding down the volume button,
press and hold the Power key as well.
Keep both keys held down together for 15 seconds or until the Galaxy A20 logo shows on the screen.

When the phone has finished the reboot, try to see if it still keeps freezing and lagging. If it does, then let us know.

yes sir

ok @giri of not download then do above steps which i I mentioned earlier and observe
