My A52 is extremely lagging

[Chainoo]

Hello, My Samsung A52 is extremely slow that I am almost unable to use it especially I can't type because it just mess up. I've tried a lot of things including resetting my device. 

Note, my phone was repaired some times ago. It's wireless connections(WiFi, Bluetooth, Hotspot) don't work after repair. But recently they started working for some hours.
