Try going to recovery mode
Power off your device completely.
– if the phone doesn’t boot recovery after you complete the guide, then you have to remove its battery and re-insert it after a few seconds, then repeat the guide.
Boot recovery mode by pressing and holding Volume Up, Home and Power, all at the same time.
Release all buttons when the Galaxy S5 screen flickers and the main Recovery screen will appear.
In the recovery mention do a wipe cache.
If this still doesn't work, do a factory reset. Please note this wipes all of your data on the phone.
If you can't get into recovery because it involves the home button, then there is something else wrong, like maybe a defective daughterboard.
