1) Connect the phone to a plugged-in charging lead that you know works. Check that the connection between the USB, plug and socket is firm.
2) Wait half an hour. If the phone shows no sign of turning on either by itself or when prompted, try holding the home button and power button down at the same time for up to 20 seconds. If the phone switches on and you see the Apple logo, release the buttons.
3) If that still hasn’t worked, connect the phone to a PC or Laptop that has iTunes installed (preferably the one your phone is backed up to). While plugged in, hold the power button and home button for a minute or so. Your phone may turn on and enter recovery mode, where you’ll be prompted onscreen to perform a full restore. If this still doesn’t work, take the phone to the Apple Store.
1) If your Samsung Galaxy device contains a removable battery, take it out and hold the power button down for a minute or so. Put the battery back in and try starting the device up again.
2) If that didn’t work or the battery is non-removable, try plugging the device into a charger and leaving it for 15 minutes. Be sure you’re using a charger that works.
3) Try rebooting the phone. To do this, press and hold the power button and the volume down key for a few seconds and release.
4) Next, try booting it up in recovery mode. To do this, hold the power, home and volume up buttons together. Release the power button if the phone vibrates and you should then see a recovery screen.
5) If none of these options have worked, take your phone to a technician or back to your service provider.
1) Make sure the power outlet and charger are connected and working properly.
2) Leave the device a few minutes to see if it starts up or if the battery icon appears. After a while, press and hold the power button for 30 seconds to see if it turns on.
3) If it doesn’t, connect the device to a powered-up laptop using the USB cable. After 10 minutes, disconnect the USB cable and then reconnect it within 10 seconds. Wait 1 minute and see if the battery icon appears on the screen. If not, press and hold the power button again.
4) If that doesn’t work, press and hold the Volume Down button and the Power button at the same time for at least 10 seconds. Hopefully you’ll see an Android robot and the word “Start” with an arrow around it. Press the Volume down button to move through options until the screen shows the option to Power off. Press the Power button to select that option. Disconnect the charger and reconnect it within 10 seconds and if a battery icon appears on the screen, allow your device to charge for at least 1 hour before turning it back on.
5) If this doesn’t work, seek support from wherever you purchased the phone from.
1) Make sure the charging cable is working and properly connected.
2) Hold down the power and volume buttons together for 10 seconds.
3) If this doesn’t work, repeat but try shining a bright light into the phone’s sensors and camera.
4) If you still get no response, consult your service provider or the store you bought the device from.
