Re: should i download cleaning app for samsung galaxys4
In my experience cleaning apps don't do much to help. What you can do that prolly will yield benefits is clean your cache.
Go to settings~~>storage~~>Cached data. Tap Cached data to clean the cache.
Further, you can wipe the cache partition by:
1. Turn off your phone
2. Press Volume Up+Power+Home until the phone vibrates. When the phone vibrates release the Power and Home buttons but continue to press the Volume Up button. This should land you in the Recovery Menu. You may release the Volume Up button.
3. Once in the Recovery Menu use the use the Volume Up and Down buttons to navigate the options and the Power button to select Wipe Cache Partition.
4. When done, select Reboot and Bam! You've cleaned up and your phone will be happier.
