I got about a 2-3 weeks left before the season ends, I've just started like a month ago and I've been grinding to get to Ace-V just to get that Banner in the Season Shop and maybe that Patch as well and I'm really dying to get it.
Well here's the problem, I have a Potato phone, I can Kill and stuff and some clutches as well but the one that's holding me down in the Lags and Frame Drops, In pvps and especially when there's a lot of player in one spot or heavy gun fights, I managed to get to Master-V but I still need 24 more stars for that Ace 😭
I grind at times and sometimes dedicate a whole day just grinding but I barely make a scrap in rank points, losses and especially lose streaks kills me, I'll be buying a new phone but not anytime soon and I can't just "Get Good" when my potato phone is holding me down.

Can any of you doods help me out in what to do to rank up fast in my situation?
Should I just camp? Go Solo? or anything (Info on how rank points work?)
I'm really invested in this game, that's why I really want that banner ;-;
