When certain applications no longer function properly or if your Samsung Galaxy S 4 LTE is very slow, you can reset the device to its factory settings. This will reset the telephone to the settings it had when you first turned it on.
Please note: your Samsung Galaxy S 4 LTE may request a security code, which, if necessary, can be found in the instructions of the Samsung Galaxy S 4 LTE. Make sure you have them at hand.
If you purchased a used device and do not know the code, you should ask the previous owner for it.
