OnePlus 12 Freeze/Blacked Screen, Random Restarts and Sim unavailable
I bought my OnePlus 12 (Indian variant) in July 2024. Since last two weeks, the phone has been acting up and it's gotten much worse over the last few days. I've had well over 150 incidents, with 20+ today alone.
The phone will randomly freeze, the screen goes black, touch stops working completely, and the only thing I can do is force it to shut down. Sometimes the SIM disappears, and other times the phone just restarts itself.
I contacted OnePlus support and followed everything they asked me to do. First a factory reset, then a full software reflash. Neither fixed the issue. If anything, the freezes seem even more frequent after the reflash.
I took it to the service center yesterday for flash. When flashing also didn't help, then their response was that it could be a motherboard issue, but they aren't sure. The proposed solution is a motherboard replacement costing ₹32,500, but they also said they can't guarantee that replacing the motherboard will actually solve the problem. Their other suggestion was basically to buy a new phone.
I have attached a video of the issue as well.
Has anyone else faced similar issues with their OnePlus 12?? Any help or suggestions would be greatly appreciated. Thanks
