Mekotronics R58 review – Part 2: Android 12 on Rockchip RK3588 CPU

RK3588 mini PC SATA SSD

I’ve written the first part of Mekotronics R58 review last month with an unboxing, teardown, and first boot with 3D graphics benchmarks. I’ve now had more time to play with Android 12 on the Rockchp RK3588 mini PC, so I’ll report my experience with the device. User interface and settings As already mentioned, the box ships with Android 12 for TV and the stock launcher. The Google Play store is working, and I had no troubles installing all apps I needed for the review. Most of the settings are pretty much standard. While the first time, I used Ethernet, and also tried WiFi 6 connecting the R58 to Xiaomi Mi AX6000 router. It worked but not without some effort, as initially, all I got were messages like “Couldn’t find SSID” both with 2.4GHz and 5GHz SSIDs. It turned out I had to disconnect the Ethernet to make WiFi work, and […]
