I have an S3 and a Micromax a110 . I have used Micromax service and Samsung service. Both once. Micromax kept my phone for 20 day's and Samsung for 1 . They changed the entire board and returned the phone in 1 day . Micromax changed my in call speaker for 20 days . But still for daily use I use Micromax and when travelling by car to work I use S3 . Never s3 in train or bus. . Too scared to scratch it or loose it . Micromax is use and throw .
