I recently got the same phone! Mine doesn't crash, but what amazes me is how slow it is -- The flip phone(s) from circa '05-'08 that I had been using weren't fast, but this Alcatel / KaiOS feels like it's running an interpreter in a virtual machine and waiting for network roundtrips on every keystroke ... I mean i'm exaggerating but the lag for all my actions is a real bummer.
The UI and functionality would be nice if not for the bugs. Maybe they have fixed a bunch of them in later releases, but my provider isn't providing updates.
