I do not see it that wayfrom sounds the camera upgrade is basically normal S22 level not ultra level.
I would say this would be a good upgrade for fold 2 users but not for fold 3. basically seems very close to same as fold 3. very minor improvements.
Almost every aspect has had a refinement and given most are only paying $2-400 to trade up from a F3 which gives you another 1+1 years warranty and screen coverage, a new case and pen, free screen saver replacements and a generous E voucher, that makes it almost a bargain for us techies
