Lava x11 is a good phone, I would only say good because anything more than that would be unfair to say.
I brought this phone from Mumbai , specs are good. It is promised to receive a marshmallow upgrade.
Within few days of me having brought this phone, I got an update of around 360 MB. , I thought it is marshmallow one, as nothing was descripted within the update. I initiated the update process, phone updated and since then it is facing major issues.
