If your Android phone or tablet won't turn on, here are some steps you can follow to try to fix it before giving it up:
Has it fallen into water or gotten wet?
If your electronic device has fallen into water or gotten wet and has stopped turning on, you must be very careful, first of all do not try to turn it on or connect it to the charger as you could permanently damage it.
Dry the exterior completely and place the device in a bowl of rice, leave it in for several days without touching it or removing it, this way the moisture that has entered will be extracted.
Check the battery charge
1. Connect to a charger: Make sure you use a working charger and cable, preferably the original cable, and check the cable for any breaks. Plug it in and let it charge for at least 15 minutes, an icon should appear on the screen indicating that it is charging. Sometimes, if the battery is completely discharged, it may take a while to show signs of life.
2. Try other chargers: If the first one doesn't work, try different cables and adapters to rule out the problem being the charger. Check the specifications of your device to know which cable to use.
Restart the device
1. Press and hold the power button: Press and hold the power button for 5 to 7 seconds. This may force a restart of the device.
2. Button combinations: If the phone is not responding, try holding the power button and volume down button simultaneously for about 10-15 seconds. This may help restart your device.
Check the charging port
1. Clean the port: Make sure there is no dirt or lint in the charging port that could be preventing a good connection. Do not use sharp or pointed objects to clean the charging port as they may damage it, nor use water or wet objects.
2. Check the battery: If the phone is swollen or the battery is damaged, do not try to turn it on or charge it, as this can be dangerous. In this case, it is best to take it to a technical service or recycling point.
Does your phone vibrate and ring but the screen doesn't turn on?
If your phone vibrates and rings but the screen doesn't turn on, it's due to a fault in the screen or in the connection between the screen and the motherboard. In this case, you should take it to a technical service to have it checked and repaired.
If nothing works
If after following these steps your phone still does not turn on, it may be a more serious problem that requires professional attention. Consider taking it to an authorized technical service, especially if it is under warranty.
