On #Android Everyone is not fortunate enough to have the latest and greatest may that be because of ever raising prices of products or just lack of availability in the region. Good thing with Android is that users have full say over customization and a tip I have for Android users is that in order to make your phone feel snappier just turn off app animations.
Now this setting is easier to access with Android 9.0 just go to Settings>Accessibility>Turn off Animations
Don't worry if you have an older version of Android OS, you are still able to do this, enable your developer options by tapping on build number 5 times in Settings>About, once Developer options are on there are many options to tweak around including animations, just turn them off.
Doing this will make your phone feel lag free and snappy at no cost.
