Square-Enix is inconsistent with their mobile port release dates. TWEWY took almost 2 years to come over to Android, most of the FF remakes were on Android (ranging from a few weeks to a few months) after their iOS releases, FF Tactics is on Android only in Japan, DQVIII, as you said, were almost same-day. It's tough to predict what SE will do in regards to Android.
