[Q] Alcatel LCD Testing code?

[kenth21v]

Is there a way or a code to type where you can test the smartphones LCD?

I know in Samsung you can type *#0*# and then the LCD test will appear where you can test for dead pixels, colors, vibrations, buttons, etc.

How about in Alcatel One Touch IDOL or Alcatel One Touch Sapphire 2? I am planning to buy either of the two but I want to test it first.
(Also for Lenovo phones please.)

Is there a code for these phones? If yes please reply how, of none, please reply too. thanks !
