r/OnePlus12

My fear regarding the green line issue and my back panel coming off is telling me to replace my phone. The guy wants to give me extra money for my phone and provide his water-sealed OnePlus 12; what do you guys think?

Sharing my experience in case it helps other OnePlus 12 users.

A few days ago, my OnePlus 12 suddenly stopped working completely. I went to an official OnePlus service center, where they checked the battery. Surprisingly, the phone suddenly powered on and worked normally that entire day.

The next morning, the phone was dead again.

I visited official OnePlus service center, and they suggested replacing the battery. Since they didn’t have the OnePlus 12 battery available, I went to another service center that had one. They tested the phone with a new battery, but it still wouldn’t boot.

They told me that the motherboard was dead and that replacing it would cost around ₹32,000.

Instead of spending ₹32,000, I decided to try a local repair shop. They repaired the motherboard for ₹6,000, and surprisingly, the phone started working perfectly again.

What’s even more interesting is the battery life. Before the motherboard issue, I was barely getting 2–3 hours of screen-on time. After the repair, I’m currently getting around 6–7 hours of SOT, and the phone is working smoothly.

So, sharing this for other OnePlus 12 users: if you’re ever told that the motherboard needs to be replaced for ₹32K+, it might be worth getting a second opinion from a reliable motherboard repair specialist before spending that much.

Has anyone else faced a similar motherboard issue with their OnePlus 12?

It has battery health of 97% , is there new software updates in circulation that makes the phone obselete or faulty , is there anything i should be concerned about? (32k = 330$)

So after the latest update I'm facing new problems

1- The back button, this is the most irritating one so far! the back button is behaving as an exit button most of the time for example I'm using an app, i go to messages , i want to go back where i was but Instead it takes me to the main phone home screen.

2- no sound for notifications ( screen is off) , i thought i was going crazy or maybe I'm having problems with my ears but turns out I'm not , the phone sometimes decides not to play a sound when getting a notification ( that happens during the day not at night) and it happens even though i was using the phone 5 minutes before.

3- screen auto brightness, at night complete darkness trying to watch a video or a movie and boooom flashbang straight in my eyes! Brightness level goes to 50% and sometimes more

I'd be okay if i had a midrange phone with such bugs but i thought i bought a flagship. Very disappointed by a company that i used to like and support.

Also i don't think it's gonna get better after the OPPO thing.

Ever since i damaged the original film that came with the op 12 i cant find a good film for it i haven't tried any glass protectors ,so what are you guys using for your op12 should i try any glass protectors or is there any good tpu film.
