Xolo is a lava company product, I have been using xolo era 4g for last 1 and half month its has no problem, working just fine, camera quality is too good, overall it has some hitting issues like various other smart phones, but thats a minor problem, cause I have an old xolo phone that I have been using for last 2 years, and still has no problem except that hit issue, whenever I play games on my xolo phones it hits up. over all never face any hang issue, so I like this comany vary much, cause each and evry model has a good quality camera so I can take good photos.
