What Phone Model To Use For Basic Farm?

I have a working method to make money, but need a phone farm - I ideally want to run everything from the same model(s).

My method requires a GPS spoofing app and a popular modern social media app to be run from a smartphone - nothing else is necessary.

Please recommend a cheap model of phone that can be used for this.

So far I have tried a Nothing phone which works - but this phone is pretty expensive so it doesn't make sense to buy 50 of these.
Xiaomi didn't work too well as it is Chinese and has a lot of incompatiblity issues with GPS spoofing and allowing the app to find GPS at the same time.

YOU NEED EMULATOR
LIKE BLUESTACK.

I have a phone farm before that I used for automating crypto play to earn games. I bought 15 Xiaomi phones for $200 each.

But before I automate it, I bought 4 different phones first, Xiaomi China Version, Xiaomi Global Version, Samsung and LG phone.

The automation works well on all phones except the Xiaomi China version. SO make sure if you are buying Xiaomi phone you buy the Global Version and not the China version. I then proceed to buy more Xiaomi global version phones as it is cheaper compared to other phones.

Each phone has 30 app cloned with spoofed GPS that I modified. So app names are:
App Name #1, App Name #2, ... #30

It is switching infinitely across all apps per phone after doing the tasks for each app.

I stopped because the price of mintable coin drops and not worth it to automate anymore. I sold all my phones now with 90% discount.

If you need help to modify the app and clone it multiple times so each phone can support multiple apps and to fully support GPS spoofing, you can contact me. Send me the app name that you want to automate
