Replacement for rg405m that's just as pocketable?

Thought I'd ask for advice on what to get as my rg405m reached a point where it's hard to play on it now

It was a great device - pocketable, powerful, good screen and battery but first the screen came off (glued) and now the shoulder buttons are barely functioning. I want to replace it with something just as pocketable and something that can play DS/PSX/GBA well enough to run some games with fast forward function but also something that is NOT by Anbernic as this is the third device I have from them that has major QC issues and eventually becomes unplayable

Is retroid lite good? Is there something older that's still good like retroid 2s? Any other options?

Basically looking for something that isn't bigger than a smartphone and doesn't have major QC issues + can play DS/PSX/GBA comfortably at 2x speed
