Realme 10 4g unusable (extreme performance issues)

I have been using this device for a while, from the day i bought it ,i have been experiencing lags but i just accepted it but after the new update . realme ui 5.0 and android 14 (latest update as of december 30/2024, this device is literally unusable. it lags when there is no apps running in the background, ram expansion disabled and i cannot even open notification drawer without experiencing major lags.I have never had these issues and this is the third realme device i have owned, even the c25s didnt lag a bit . i did a factory reset, i clear cache almost every week and i cannot even use the camera app cause it takes like 20-25 seconds to take a single pic, i have almost no apps, disabled every unnecessary apps and still no good. Now is there any solution that realme will provide us with or do i need to get a new phone which will definitely won't be a Realme.
