Feature Phones
Phones that possess a certain level of features, below a smartphone but above a landline phone. They must also be phones which have a “brick” form factor, rather than a Flip Phone form factor. It is also expected that these phones will have a keypad for the purposes of dialing. For CPU architectures and operating systems, it is difficult to say, as older feature phones featured a large variety of obscurities, while newer feature phones almost always combine a Qualcomm ARM chip with an Android/Linux-based “KaiOS” install.

This phone stands out for having a physical keypad, whilst having came out in 2018. Alas, the keypad does not work in postmarketOS, probably because of it’s very weird proprietary keypad driver. However, it does boot into postmarket and actually run.
