Bluebird, the slow flipping time is preset by the game, and probably not due to your device. You literally have to flip the next card while the previous card is in the process of flipping back. Fast flipping shaves off a few seconds overall. But a few seconds can be all it takes.

That's why I stopped using the eyeglasses. The time it takes to look is not really long enough to memorise more than two or three pairs, (unless you have a photographic memory) and in those few seconds you can be flipping and matching instead.

I found Detective stage was the hardest too. Drove me bonkers at times. It gets easier, eventually.
