Every now and then, your Samsung Galaxy Tab S3 might lock up and become unresponsive. These devices aren’t perfect after all, and are prone to lock up from time to time.
If you just need to force the tablet to restart (also known as a soft reset), then do the following.
Soft Reset
A soft reset will force a restart of the device. No data should be lost when performing a soft reset.
- To force the tablet to restart, simply hold the “Power” and “Volume Down” buttons down simultaneously for around 15 seconds. This will force the tablet to shut down, allowing you to power it back up again.
If this doesn’t work and you’re still having issues with your tablet locking up, then you may need to perform a hard reset on the device.
Hard Reset
Option 1
- Navigate to “Apps” > “Settings” > “Backup and reset” > “Factory data reset” > “Reset“.
Option 2
- With the device powered off, press and hold “Volume Up” and “Home“, then press and hold “Power” to turn on the device.
- Continue holding all 3 buttons until the “Recovery Booting” screen appears.
- Use the volume buttons to toggle the highlighted select to “Wipe data/factory reset“. Once selected, press “Power” to make the selection.
- Use the volume buttons to toggle the highlighted select to “Yes“. Once selected, press “Power” to make the selection.
This process should work for the SM-T310 (WiFi), SM-T311, (3G) SM-T315, (4G) GT-P5210, (WiFi) GT-P5200 (3G), and GT-P5220 (4G) of the Samsung Galaxy Tab S3.

October 6, 2018 at 5:32 pmI have a Samsung Galaxy Tab S3. When I try to hard-boot into recovery mode, I get a light blue screen saying “This device has been flashed with unauthorized software and is locked.” How can I re-flash this device with official, supported software?

When connecting the charger there is no charging sign on the screen.
