I am using Canvas A1 for 2 years now .at first it gave me nice fedback but recently it hangs a lot .When I insert a sd card to it.It automatically hangs for 5 6 mins .
This is really bad.I also have softwear issues, .though it got every latest update.
But when I lunch an app it crashes, .Happened 80% time in a day .Battery quality is too bad.100% to 80% it take only 9 10 mins of normal usage .It often restart auto.So dont buy Canvas a1 .If if want to use new versions of andriod .Go for it guys.
