It is an FHD+ panel with a resolution of 1080 x 2400 pixels and an aspect ratio of 20:9. Under the hood, we have the Qualcomm Snapdragon 888 5G built on a 5nm manufacturing process. It is an octa-core processor with one Kryo 680 core clocked at 2.84 GHz, three Kryo 680 cores clocked at 2.42 GHz, and four Kryo 680 cores clocked at 1.8 GHz.

Coming to the optics, we get a triple camera setup at the rear and a single camera at the front. The triple camera setup consists of a 12 MP primary sensor paired with an f/1.8 lens, an 8 MP telephoto sensor paired with an f/2.4 lens, and a 12 MP ultrawide sensor paired with an f/2.2 lens. At the front, we get a 32MP sensor paired with an f/2.2 lens. The front and rear camera setup can capture 4K videos.

This smartphone is available in four color options: White, Graphite, Lavender, and Olive.

Possible ways to fix call dropping/call not connecting/mobile data issue on Galaxy S21 FE 5G

Fix-1: Switch Sim Slot

Switching the sim to another slot often does the trick when the device faces call-dropping issues. For some users, it worked. So, pull out the sim from slot 1, insert it into slot 2, and check if the issue persists. Some users managed to fix the call dropping, but the mobile data issue was still there.

Fix-2: Wi-Fi Calling

If your device is not getting a strong signal, it will likely face call dropping and mobile data-related issues. In such cases, you should use Wi-Fi calling to route your calls via the Wi-Fi network. The device’s dependency on the carrier network signal is reduced by doing this.

To enable Wi-Fi calling, follow some simple steps mentioned below:

  • Tap on Settings
  • Enable the toggle next to the Wi-Fi Calling

Fix-3: Switch Network

If you face the call dropping or call connecting issue on a 4G/5G network, consider switching to a 2G/3G. It could fix those issues. You can consider switching back to 4G/5G for accessing the internet.

To switch the network type, navigate to Settings > Mobile networks > Network mode [Sim 1/Sim 2] > Select 3G/2G (auto connect)

Fix-4: Clear Device Cache
