Samsung Galaxy A54 Losing Signal Constantly

Brand: Samsung
Model: Galaxy A54
IMEI: 351890470825596**

Since around March, I have been experiencing serious network and mobile data disconnection issues on my device. When I start a phone call, a strange static noise appears shortly afterward and the call drops. As for mobile data, although the phone shows 4.5G, the connection works only briefly and then disconnects again; I cannot maintain a stable internet connection. This issue occurs frequently and in multiple locations.

I contacted my mobile carrier’s customer service, and they confirmed that the signal strength in my area is strong. When I tested my SIM card in another phone, it worked without any issues. However, when I tried a different SIM card in my phone, the same disconnection problem continued. Because of this, I believe the issue is related to the device hardware.

I have not yet contacted Samsung customer service or an authorized service center; I am located in Kocaeli. I believe my device is no longer under warranty, but since this is a hardware defect not caused by user error, I request a free repair. If necessary, I would also like a detailed technical fault report.

I kindly request that the problem be investigated promptly, permanently resolved, and that I be informed of the outcome.
