I personally do not recommend going here for advice about tech products. You need to be way more specific. Doing some research yourself is the best way to know what would be best for you, but the smartphone industry is very big. Going to Discord servers like Dave2D or others from tech YouTubers helped me a lot to learn more about the tech world. Taking random information from strangers as facts is always dangerous, but there's hardly any other way honestly. Maybe going to a hardware store will help you. But in my opinion wasting thousands on a the most recent model of a phone is a complete waste of money. The last years model literally have close to no difference almost every time. You also save a lot of money. But I have no right to judge what you spent your money on.

Tldr: either trust strangers from a Tech Discord community or go to a hardware store and ask questions. Or do a lot of research and go into the rabbit hole of the tech world
