Phone Will Not Charge ¶
You are experiencing problems charging the phone.
Charging Port is Broken ¶
If the phone is not charging, you could have a loose charger. Check that the charger is connected to the outlet, the USB is fully connected to the charger, and that it is securely plugged into the phone's charging port. If the phone is still not charging your phone's charging port is faulty, replace the charging port using this guide.
Blocked or Corroded Contacts ¶
If the phone chargers intermittently while plugged in, the connection of the charger may be faulty. Check metal contacts on phone and charger for corrosion or debris. Use bottled air to remove any dust found within the charging cord or the charging port. You could also use a small amount of rubbing alcohol to clean the contacts. Take care to not touch the metal with your fingers because the oils on you skin can cause issues as well. If you are still experiencing charging issues, you may need to replace the charging cord. If you still are having problems after replacing the cord, you need to replace the charging port using this guide.
Broken Charging Cord ¶
If the phone will not charge with one charger, but does with another, it may be due to a broken charger cord. Look for kinks in the wire or exposed wires within the cord. If there are kinks/exposed wires in the cord, buy a new cord.
Screen Does Not Display Properly ¶
The screen is not working correctly or is distorted.
Cracked Screen ¶
If your screen looks distorted, it is possible that you have a cracked screen. Look at screen from multiple angles to check if there are any cracks. If you find cracks in the screen, replace the screen.
Damaged Screen ¶
If you hold the power button and there is no indication of powering on, the phone may have a faulty screen. Assure phone is adequately charged and you are holding the correct button. If the buttons on the bottom of the screen light up then screen may be faulty. After going through all these steps and you are still experiencing issues, you need to replace the screen.
Phone Doesn't Stay Charged ¶
Phone dies in a relatively short amount of time and/or does not hold a charge.
