I bought micromax A60 few month earlier and i must say as per my budget i think i have chosen the right choice but from few days it started giving me problem like i when i try to unlock it the display pattern get hang or the pattern goes wrong. Please it is irritating to unlock the screen and became a hassle for me to cross. Please help.

First of all you just put off the pattern mode of locking the display.
then just take it to service center and ell them that there is a problem in setting the pattern password in the fone and the display is hanging whenever I do so.

If your phone is in warranty or guarantee period than it is OK. otherwise you will be charged for that.
