Need help buying a new phone

I’m planning to buy a new phone with a budget of around ₹30,000, and I’m pretty sure I want to go with Nothing. But I’m stuck deciding whether I should stretch my budget a bit and go for the newer 4a/4a Pro, or just stick to my budget and get the older 3a Pro.

My main priorities:

- Camera quality (this is the biggest one.. I’ll be using it a lot for photos)

- Good storage

- Decent overall performance

Also, I really liked the new pink variant they launched, which is kind of tempting me to go over budget 😭

So I wanted to ask:

1. Is it actually worth stretching my budget for the newer 4a/ 4a Pro, or is the 3a Pro still good enough in terms of camera and performance?

2. How big is the real-world camera difference between these models?

3. Does the newer one have significantly better processing, or is it mostly just marketing?

4. What’s the cheapest way to buy it in India?

5. Are there any student discounts available anywhere?

6. Which platform usually gives the best deals — Flipkart, Amazon, official site, or offline stores?

7. When do prices usually drop? (sales, card offers, etc.)

8. How is the long-term performance and durability of Nothing phones?

9. Any common issues I should know before buying?

10. Are there better alternatives in this price range that I’m ignoring just because I’m fixated on Nothing?

I don’t want to make a dumb emotional decision just because I liked the color, so I’d really appreciate honest opinions, especially from people who’ve actually used these phones.

Thanks!
