A:AnswerIt has cast feature but I haven't tried yet as it's so slow and lagging, my mobile phone and previous tablet both Samsung work great casting to roku and all other normal usage. But the one, oh my, wasted my money here. Just download the cast app on roku and as long as they're on the same wifi it should work my concern would be lagging and annoying to watch anything through this device.
A:AnswerYes, but your level of success is going to depend on the devices you want to cast to being compatible, discoverable, your WiFi capability and configuration, and what apps you cast with. This tablet casts photos and music to my Samsung TV OK, videos not so well, and so far I can only find one app that sort of successfully plays to my AirPlay speakers. If you are used to iTunes, AirPlay, Apple TV etc, the Android equivalents can be just as simple or horrendously frustrating depending on all the factors I first listed above.
A:AnswerThere is, the basic one from the manufacturer. You can also buy one from Best Buy, which I did one the very first one, when my child was very young and knew the chances were high that it would be broken before too long!
