android slider phone becomes retro-pocket-computer

This is an LG Enact,a slider phone from around 2013, one of the last phones with keyboards. The 5 row keyboard means a lot of the usual symbols are easily accessbile and makes it a great pocket-computer. I installed FreeBox which is a DosBox port that works on Android 4.4, which is what the phone is stuck with. I’ll be using mainly to study assembly programming.
