There have been reports of running Android 11 on a small computer, the Raspberry Pi 4.
Originally, the Raspberry Pi runs on Linux. This structure is the same ARM as the Android operating system, but it was also difficult to operate Android due to lack of drivers. However, according to a report submitted by a man named Max Weninger on the Developer Forum (XDA-Developers), it has succeeded in getting the Android 11-based OmniROM running on Raspberry Pi 4.
In the Raspberry Pi 4, Android 11 operates in tablet mode and can be operated like an Android tablet, and the Play Store is also available. However, it is said that there are limitations to the graphics unique to tablet mode. Related information can be found here .
