AhamedGhalib I saw a similar post in the community, though I’m not sure if that one was also caused by a software update.
If an update ends up causing issues like this, it’s definitely not good and shouldn’t be happening.
If you’re not planning to spend around ₹15k on a motherboard replacement at the authorized service center and thinking of buying a new phone, I’d suggest getting a second opinion from a good board-level repair technician. They can check if it’s something repairable. In some cases, CPU/RAM reballing can bring phones with similar symptoms back to life. It usually costs around ₹3k, though there’s no guarantee it’ll fix your phone.
If it does get fixed, you can use it for a while or exchange it when buying a new phone. Phone (3a) Pro’s exchange value is around ₹14k, so you could end up saving a decent amount while purchasing a new phone.
