BLU R1 HD receives new update that adds T-Mobile VoLTE and band 12 support
The BLU R1 HD is one such device, and those purchased it can confirm that it does its job as a daily driver. The smartphone made its debut in the United States several months ago, but it lacked support for certain bands.
BLU R1 HD owners will be pleased to know that the update also includes some Android security patches, though we're not certain if BLU added the October or November security updates.
The update is rolled out OTA (over the air) in waves, so make sure you check from time to time it's not available for you right away. It's worth noting that this is a fairly sizable update at 372MB, so make sure you have enough storage and battery before applying the update.
