Xperia C is not worth to have.!
Having only 4Gb of internal storage you can’t download more apps in it.!
Also rooting an xperia needs lots of efforts. Its camera is not good and front camera is worst I have ever seen.
And also its having some problems with its power button.
And the worst part is that the customer service of SONY is unfavorable or bad one don’t like it.
Don’t go for it seriously.
