How to fix homescreen lag / slowness
Depending on how your phone is set up, sometimes you will see lag when swiping between homescreens. There are a number of things you can try to fix this, as follows:
First, try restarting your phone. This will fix many problems.
If that doesn’t work, then remove any Widgets that pull data to the phone, such as Twitter, Weather widgets etc.
If you have Live wallpapers turned on, then try turning them off by going to Settings – Wallpaper, then changing to a different Wallpaper.
Go to Settings – System – Developer options – Window Animation Scale and Transition Animation Scale. Try changing these to 0.5x (or even 0).
(you will need to unlock Developer options if you can’t find this. Use the search form on this site).
Sometimes the problem can be with the phone or operators skin or launcher, so try going to the Play Store and downloading a third party launcher such as Nova launcher or Go LauncherEx. Note: you will need to re-create your homescreen shortcuts, but they are both great launchers.
Another tip is to always press the Back key instead of the Home key when leaving Apps. The Back key will often close the App properly, while the Home key can leave it running in the background.
