This Reliance jio phone was tough for normal people usage, because phone keys are different, mainly delete button. Phone have 4g feature and 2gb internal memory is available for user, Internet browsing available but it is tough to use for browsing. Other apps are not able to install in the phone, only jio apps are available. Screen casting is possible, needs to buy a media cable. Phone wait and you can import contacts from mail. Phone heating in long time calling, digital calling clear based on area signal strength. I am not satisfy while it was hanging, some times irritated.
