Motorola 4g is good option under this 1300- 1400 price range, speed is very good.
Look of Motorola 4g is also good.
Yes its convenient and easy to use
Yes video calling is disappointing, one more thing is mobile heating, this will be more warm while charging and while talking to someone for long time.
Sound quality is good and okay.
Cameras are okay giving good quality. Almost All essential apps are inbuilt excepting some are.
Overall I giving a good complement to Motorola 4g.
