That's still a problem unfortunately, though less so than it used to be so your perception might depend on when you last used it.

If you're interested, you could try perhaps FlatJewels from the play store. It's a simple game with a fairly quick loading time (except the first run, which is always slower). I don't know if the author put effort into specifically optimising its start time, but it's probably fairly representative of what's currently normal.
