No user replacable battery, no SD card slot, no headphone jack, i’m guessing that since its a new samsung there’s little to none avaliable custom ROMs for it. to be absolutely fair the note 20 ultra I’m using to write this comment is basically the same when it comes to a lack of these things except for the sd card slot.
there might be an BIOS update you could try i don’t think it will fix 64 bit and even if it did 32bit apps probably take less memory for storing addresses.
on my AOD255E 64bit just works :tm:
