To summarise awnsers: you can do anything on android. It just takes more time to set up. But changing background pictures and things like that are things that were always available on android, and not just that, you have much more options of editing things as background, contacts, etc… So it depends on you.
You can either stick to apple, which doesn’t offer anything new or doesn’t let you do as much as a nothing phone, but it’s easy and fast to set up, or you can buy the nothing phone 2a plus, which would allow you to do anything, and it’s a generally far better phone, itll maybe just take a little more time to set up.
The good thing is, nothing contains chatgpt pre installed. Log into it, and ask it anything you’d like to do. It will help you with it all, it knows everything, so you just have to ask anything you wish to do, any chatgpt will write you a step by step guid to exactly do as you pleased. Seriously, you’ll be able to do everything you can do on your iPhone and more, so don’t worry about being limited from the iPhone, you’re limited on your iPhone compared to Nothing phones.
