Hard Reset
If you’re having continuous technical troubles with your Galaxy S6 where it will not start, freezes constantly, or malfunctions, you may want to try a hard reset. A hard reset will erase all data from the memory of the device and set it back to factory defaults.
Option 1 – From Startup
- With the Galaxy S6 powered completely off, press and hold “Volume Up” + “Home” + “Power” buttons simultaneously.
- When the Samsung logo appears, release the “Power” button, but continue to hold “Volume Up” and “Home“.
- When the “Android system recovery” screen appears, release all buttons.
- Use the “Volume Down” button to toggle the selection to “wipe data/factory reset“, then press “Power” to choose that selection.
- Use the “Volume Down” button to toggle the selection to “Yes — delete all user data“, then press “Power” to choose that selection.
- Wait for the reset to finish. You will eventually be prompted to “Reboot system now“. Press “Power” to choose that selection.
