Why did my mobile phone keypad suddenly stop working?
There are several possible reasons why your mobile phone keypad may have suddenly stopped working, such as a software glitch, water damage, or physical damage to the keypad or phone. It is recommended to troubleshoot the issue by checking for software updates, checking for water damage, and inspecting the keypad for any physical damage.
Can I use an external keypad with my mobile phone if the built-in keypad is not working?
Yes, many mobile phones support the use of external keypads or keyboards through USB or Bluetooth connections. Check your phone's user manual or do a quick internet search to see if your phone is compatible with an external keypad.
