I have at least 100+ balance left on my account and I've been wanting to upgrade my p20 pro to p30 pro yet I'm having doubts as I'm only looking forward to it about the camera and I'm not sure if ROM/RAM will be good enough for gaming. Is there any suggestions? That would be appreciated.
P. S. I'm also planning to trade my phone in order to get some credits and save some money.
Welcome to the community!
It's totally up to what you prefer, since you already have a Huawei phone then upgrading to the P30 pro might be the better option for you.
