How to wipe android phone

If you have problems with your Samsung Galaxy S4 and that the smartphone isn't working properly, a good solution to this is to wipe the system cache of the phone. You don't even need to do a hard reset. In fact, doing a system cache will NOT delete any of your personal info, but only the background and application cache. Cache is stored data on the phone which allows apps to load quicker, it's like the data is on standby until you need it again. Wiping it simply means that the app will have to reload the data.

Here's how it's done:

• Turn off phone 
• Remove the battery and reinsert. 
• Hold down the Home and Volume Up keys 
• Press and hold the Power button while still holding the other keys. 
• As soon as you see the Samsung logo, release all keys/buttons. 
• Press on the Volume Down to scroll down to Wipe Cache Partition. 
• Press the Power button to select it. 
• Press the Volume down button to highlight "Yes" and press the Power Button to select it. 
• Wait for a few minutes for the phone to clear the data. 
• Then press the Power button to select reboot system now. 
• Wait for your phone to reboot.
