Flip phones with external screen

Somebody please help!

Right, mum has a smartphone, no idea how to use, goes to sleep in the middle of whatsapping!

Me? I love a flip phone. I'm mum's carer, 49, frazzled and my phone is dying! I have ALWAYS had a little flip, started with a Samsung A800, then a E330, 270 or something like that, darling little phone that didn't take an SD card, a Nokia flip in the early 2000's, horrible thing that was a bugger to open, then I had to have a bar, fab battery but didn't like it (good as an alarm clock though!) then my last 2 have been Doros! And there is my problem.

My current Doro is the 6530 and it's having issues, SIM issues, battery issues, I've had it over 3 years and I think it's knackered. BUT, it does all that I want, I can assign ringtones from my sd card for contacts, so I know who's calling, texting is simple and it has external screen. A few years ago, before I bought it, I got a flip off Amazon and when texting, the space button was not at the bottom like all normal keypads it was at the top, well, I started out as a typist, then a data inputter so having mobile phones with a space button at the bottom is well ingrained in my brain , so that phone went back!

I NEED a flip, dual screen, decent sized buttons and lanyard compatible and not too heavy as I don't Have pockets, it goes down my bra!

Any of you any ideas?

Text/call only, all the other stuff not necessary.

Thanks
