My Apple iPhone 12 Loses Network Connection When Charging or At Random Times

I have been experiencing network problems with my iPhone 12 since the day I purchased it, leading me to send it to the service multiple times. Whenever I perform an update or plug it in for charging, the network drops. Even when using navigation, the signal disappears instantly, causing the phone to shut down unexpectedly. My phone has been to the service more than 10 times and is still there. This situation has become a significant inconvenience for me. The updates provided to resolve the issue are ineffective, and my phone is consistently returned without a solution. The authorized service center, Troya, and Apple support have been unable to identify the root cause or fix the problem despite multiple attempts. Each time, my phone is reset, and my screen protector is damaged. This situation is causing both financial and emotional distress, and Apple fails to stand behind the product it sold. Contacting Apple support has not yielded any solutions; instead, I feel as though I am being stalled, wasting my time. Despite the significant amount paid for the product, I believe the customer service lacks a solution-oriented approach. I request a replacement for my phone. If you check the system, you can see how many times it has been sent for service due to the same issue and how widespread the network problem is, should you wish to investigate.
