You can check out the Samsung S20 FE 5G, available at 32k on Amazon right now, additional discount will be available on select cards. I am thinking of buying it for my sister, wil cost 30.4k with the ICICI Amazon Pay Credit Card.
Btw OnePlus isn't nearly as bad as everyone has been saying around (surprisingly almost none use OnePlus themselves). Although at 20-30k budget there are better phones out there (thats why reco S20 FE 5G over Nord 2), but OnePlus still gives you a decent all round package for its price considering hardware, camera, and especially software, because even after the sellout Oxygen OS is still one of the best Android version presently. I just got my OnePlus 9 Pro 12 GB stolen last week, bought the same model again for 49k, worth the re-purchase at this pricepoint.
