I purchase this mobile since 2 years. Its really bad. When I used it, I find many defect and problems in this mobile. RAM is so low in this mobile, ROM is also very bad. We can use external memory card just upto 4GB. Battery backup is also very bad.
We cannot download more than upto 4-5 aps. If we will try to download more apps than it will hangged and you faced very difficult to uninstall app and use any apps.
I recommended you that dont use this mobile. For this generation its unsetisfied phone.
