In this case, the form factor is of a clamshell phone which can be opened and closed to reveal the display and keys. Like the feature phones, the architectures and OSes vary, as older flip phones were mostly obscure in this sense, while newer ones almost always pair Qualcomm ARM chips with an Android/Linux-based KaiOS install.
