Is a bigger screen possible?

Ok,
My platform is Mobile: Android
My town is on my phone which is a Samsung Galaxy J7

It would really be nice to play on a larger screen.

What are my options (if any)?

Thanks

Is this for another phone? I take it a tablet isn't practical for you?

If it's for a mobile only, I looked your phone up and it says it has  a 5.5 inch screen. Is this correct?

If that is the case, then bigger is definitely possible. It will depend on a few things.

1. Budget
2. Brand. Do you care what brand it is.
3. Specs. What is important to you on the phone. For example camera, battery life.

What about something like the:

I have a Huawei phone, but given the companies uncertainty (access possibly being restricted) in many countries right now personally I would avoid getting a new model of this brand.

You can also play the game on any android tablet. As long as you are logged in with the same google user name, it will be the same township game.

Also, you can install Play store on Amazon Fire. On some newer Fires this is a bit flaky so it doesn't work well, had to use Facebook to transfer game. On the older Fire, I happily log in with my google account and install Township from Play store.

Lastly, you can play on Ipad and Mac too, but you will need Facebook to transfer the game. If you are not using it, you need to contact Playrix support.
