For litecoin, on my two mobile devices, it is not synchronizing at all now after I left it open for 5 minutes 0% synchronization. I tried it just now.
For dash, on both devices, it is very slow. The synchronization got to 26% after 5 minutes on the first device while 38% after 5 minutes on the second device. Also I tried it just now.
That is not the only problem if you have this kind of coins. If you want to send them, it can be pending for minutes and later become failed. It happened when I wanted to send litecoin in the past. I tried it there times before it was send successfully. The third time that I sent the coin, it was first pending for several minutes if not hours.
