Cheapest smartphone for LEGO – Xiaomi Redmi 7A

Since the introduction of the Boost system, the Powered Up and Control+ sets I read a lot of complaints about the smartphone requirement. People usually does not want their kids to use the parents’ expensive devices to play with LEGO. I decided to find the best option for a phone that meets the requirements of these applications but still reasonably priced and easy to get.

This is the Xiaom Redmi 7A, a phone around $100 that works with the LEGO control apps just as well as the $400-500 mainstream phones. Black Friday is coming, there are some sales going on so check the links below for the current availability and the price:
