Hi again @Sudhan_23,
Have you checked whether there is a software update available? Find and tap Settings > System > Software update. It might also be a good idea to check for available app updates. Open the Play Store > Tap the three horizontal lines in the top left corner > Tap "My apps and games".
Have you tried rebooting your phone in safe mode to see if the menus are running slow there as well? Safe mode is a troubleshooting mode where all apps downloaded from Play Store is temporarily deactivated, that way you can see if there is a downloaded app causing the phone to act slow
The easiest thing to do to improve the charging rate is to use a quick charger instead of the charger that came in the box (UCH20). As it is always recommended to use original chargers, I would suggest that you try UCH12.
Regarding "perfect camera settings", it is practically impossible to say which settings are optimal due to the fact that one set of settings works better for a specific kind of surroundings and while another set of settings work better for another kind of surroundings.
