The ESP32 community is really creative. Like, really creative. Every week, there’s at least one cool new project that someone has worked hard on, complete with open-source code and a full guide on how to make it at home. But sometimes, something incredible comes around, and today just so happens to be that day. Someone has shown off an ESP32-powered 4G smartphone on Reddit, and as you might imagine, the comments are full of people clamoring for the source code, the hardware used, and everything in between.
