I currently own a iPhone 7, so I want a phone with bigger display if I buy an android I will keep my iPhone but if I buy an iPhone Xr then I’ll sell my iPhone 7 cause I like iPhones and I don’t want to live without one. So should I buy Oneplus 6t or an iPhone Xr ?
What you get is up to you, one is Android the other is just an upgrade to what you have now. Since you are looking at the iPhone X you are not really worried about prices. If it was my phone, I would keep the 7 and use it till it's too slow in running modern apps.
