Which gamepad will you use?

Hi! I bought recently this phone and it’s really good on its own, but, if i want to use it with emulators and that sort of stuff, which controller you think will suit the phone? as it has a bulky back

I seen the Betop G2 from Huawei, but i’m not sure if you can use it on any other device that’s not a Huawei one

I will wait for your answers and tell me which one you are using!
