Don't bother. Flip phones have enshittified, too. (Alarms don't consistently trigger unless you disable and re-enable them after setting them; sometimes the sound just breaks until the phone's restarted; if any voicemail expires then the phone's voicemail indicator is stuck there forever; J2ME support has been removed, so the only available games are the ones you have to text a premium number to "buy" (even though the software comes pre-installed).)

Multiple different brands have the same buggy OS, even those which used to be household names. This must've saved the companies at least $20 000.
