I'm using M2S now for 6 months...performance better than my Note II. Only screen small (720P IPS 4.3") hence causing eye strains if reading articles more than 10 minutes.

Built Quality impressive. Fall 2 times without protective case from 1.5 meters height still good. Only cause defects on the rounded edge..very minor.

Camera 8MP with acceptable quality. Night shot not so good producing a lot of noise. In door shot quite good cause i always use this to take photo in Engine Room.

Overall very satisfied with the phone. I was about to get a Nexus 4 for outdoor work due to bulky size of Note II which can't fit in my coverall suit pocket properly...i laugh when the contractor gave me this phone. She told me its the best phone in China & u cannot buy in shop. I laugh but then only i notice almost everyone in the yard will try to get one...they will come and ask from where u get the phone..its really popular there...nobody cares when u have Note II, IPhone, S3 etc..hahaha...

go to display setting...there you can find launcher preference.
