Hi ishaan_kumar, LG WRman Greg here,
You can use the Smart Share app on Google Play to sync your smart phone with the LG 3D TV. However, the app is best used for sharing files and images only. If you want to watch movies streaming from the phone, then it might be a bit slow. This works on all DNLA-certified devices. Just remember your phone must log on to the same wireless network as your TV so that the TV and the phone can recognize each other.
If you have any more questions feel free to ask or check out the official site for more info at 3D TVs: Discover 3D Televisions | LG India.
LG WRman Greg out!
