I can only speak to iOS devices; I have successfully run V&H on an iPad Mini 4 (which, although the most "current" model, certainly would never be considered a gaming platform for anything more than Solitaire) with no problems.
Can you download it, and just try to see if it will run? (Sorry, I have zero experience with the Android OS)
what about a Galaxy tab E? Got my daughter one for her birthday and she is not able to get the game on it. Game doesn't show up in the play store. Will the game be available for the Tab E in the coming expansion? She was really looking forward to playing on her new tablet inside of her phone. Game works fine on my 3 1/2 year old Galaxy tab A and my hubby's newer Galaxy tab A.
Unfortunately most models of the Galaxy Tab E are unable to play the game due to not meeting hardware requirements - Villagers & Heroes is a fairly demanding game and as such it won't run on many lower-end devices, depending on their individual configurations.
The coming expansion will not change this, sorry - all I can advise is to try another tablet. I can always check up compatibility for you in advance if that helps!
