My phone's face unlock feature is most of the time fast but sometimes it performs slow or says "No Face Detected".
When I play games (1hour) it heats a lot.
And I also feel very sad thinking how it is the successor of A50 as it hasn't inbuilt screen recorder compared to its predecessor A50.
Almost every phone has march security patch but A51 is stucked on Feburary security patch.
