DEAR FRIEND, YOU WILL HAVE TO CHANGE THE TOUCH PAD OF YOUR PHONE.

Hi,you will have to replace the flex of the phone.
The flex make the touch pad to function,also the functioning of the number keys.
When you replace the flex the touch pad and the key will function again.

Thanks for using fixya.

Check by swapping the keyboard. You might have a stuck windows key (the one with the windows flag on it)....

Hi, when a phones touch screen malfunctions, it means that the touch pad is damaged seriously and it needs to be replaced.

Mostly it is caused by dropping the phone on the flow, hitting it on something or even pressing the touch screen pad with the wrong instrument.(any sharp object).

You can take it to a here by store for a replacement.

NOTE: phone is very delicate needs to be handled by an experienced personnel.

Take care.

Try this. Touch Keypad simulates a wireless phone keypad on the touch screen to allow you to enter text, numbers, and symbols just as if you were using a wireless phone keypad. Touch Keyboard simulates a 20-key QWERTY (typewriter) keyboard on the touch screen to allow you to enter text, numbers, and symbols similar to the way you would using a QWERTY keyboard. To use Touch Keypad or Touch Keyboard:  In a program, tap the Input Selector arrow, and then tap Touch Keypad or Touch Keyboard. To type lowercase letters, tap the keys on the dial pad or keyboard. To type a single uppercase letter, tap the Shift key and then tap the corresponding key. To type all uppercase letters, tap the Shift key twice. To change back to all lowercase letters, tap again. To enter a space after the word, tap the Space key. To start a new line, tap the Enter key. To backspace and delete a single character in any input mode, press the Back key. To open the Symbol pad, tap the Symbol key. To change the input mode:  Tap the Input mode key to switch to a different input mode: XT9 (predictive), Multitap (abc), or Numeric (123).

Hope this helps, let me know if this works or if I can help you with anything else.

recalibrate the touch screen

my lg's camera started to turn my phone off, i do tech work for a wireless company and when i was trouble shooting my own phone as a test i went to my camera and my screen went blank! i tryed every thing, but the master reset. because my screen is blank i need to know the number i will have to enter to get it reset from the key pad.

Try resetting ur phone by holding the red and green buttons while hitting the reset button on the bottom with the stylus. All the information u have saved in ur phone will be lost but it will work afterwards.
