I Can’t Get Network Signal on My Samsung Galaxy A55 5G—Only Works on Wi-Fi Calls

Two weeks ago, I purchased a Samsung A56 smartphone from Media Markt Izmit 41, paying ₺20,000. Since the very first day, I have been extremely dissatisfied with the device due to multiple issues.
The most critical problem is the Wi-Fi connection. Even when my modem is just 3–5 meters away, the phone either loses the connection entirely or barely shows the network. Shockingly, even my 10-year-old phone performs much better in the exact same environment, which shows this is not an internet issue but a device defect.
Another recurring problem is with the contacts app. I use dual SIM cards, and managing my contacts has become nearly impossible. When I try to organize or copy entries, the data constantly gets mixed up, and in some cases, contact details disappear completely.
These issues have been present from day one and make the phone highly unreliable. I contacted Samsung customer service, but their only advice was to send the phone to service. I find this unacceptable — a brand-new device should not have to go in for repair within two weeks of purchase.
I am therefore requesting a full refund for this defective phone. No customer should have to deal with weak Wi-Fi reception and unstable contact management on a newly purchased flagship device. Samsung must take responsibility, and I ask that this complaint be resolved swiftly so others do not face the same frustration.

For the past two days, I have been dealing with a serious issue on my Samsung Galaxy A52. Even though Airplane Mode is turned off, the icon remains dimmed as if it’s still active. Because of this, I cannot make phone calls or connect to the mobile network at all. The problem appeared suddenly, witho...
