By now it is very obvious, it is either you are a iOS, Android OS or Window Phone OS. For me, I am for now a Android OS user for my phone.
Being a smartphone user (mine is actually a budget entry smartphone), we tend to most of the time got carry away with all the hypes about the apps and features of the phones. Like my friend said, it makes us keep attaching and playing with it. Many a time we forgot the needs to maintain it (I am also at fault).
Here might be some useful tips on some steps to maintain Android phone performance.
1. Clear the Cache
Have an app that's always crashing? Rather than force-closing or uninstalling it, try clearing its cache. This simple step will help resolve most of the issues that troublesome apps may be experiencing--and it won't create new problems, as forcing the app to shut down might. To clear an application's cache, open the Settings menu on your phone and click Applications. Then select Manage Applications and tap the app that's been having problems. Don't worry--all of your data and settings will remain intact; you're just getting rid of temporary files that may be causing difficulties.
2. Uninstall Apps
3. Clean Out Your Memory Card
Cleaning out your SD Card may not boost your phone's performance, but it makes sense to remove any old or unused files that are just taking up space on the card.
