A quick review of the D-Link Portable Digital TV Receiver for Android on a Galaxy Note 4.
After making the review I also tested the TV receiver on a Nexus 5 and it simply did not work, the app crashed as soon as I plugged in the device. Make sure you check if the TV receiver is compatible with your device before you buy it.
Also, this device may not work in your country. On the packaging of this particular model (DSM-T100) it says it only works in Australia and New Zealand.
I have done a bit more testing and the included antenna is not completely useless it does work in an outdoor setting. The video gets choppy and breaks down a bit in a moving car though.
