SAMSUNG Galaxy A16 4G (SM-A165M/DS)

The wireless charging function is not available on this device. This may be a drawback for users seeking convenient charging options without the need for cables. Wireless charging can be useful at home or in the office, preventing cable clutter.

The water resistance function is not included, so users should exercise caution when using the phone around water or in wet conditions. Without water resistance, the phone is more susceptible to damage from accidental splashes or exposure to rain. This could limit its use in certain environments.

The expandable storage function is not supported, meaning users are limited to the internal 128GB storage. Users must manage their files accordingly, potentially utilizing cloud storage or external drives for additional space. This limitation may affect users who require large amounts of storage for media or apps.

The dual SIM function is a valuable feature for those who need to manage two phone numbers simultaneously, providing added convenience and flexibility. This is particularly useful for separating personal and work phone lines or for using different carriers for domestic and international calls. It simplifies managing multiple phone lines on a single device.

The reverse wireless charging function is not available, limiting the phone's ability to charge other devices wirelessly. This feature allows a phone to act as a wireless charging pad for compatible devices like earbuds or smartwatches. Its absence may be a drawback for users who want to share battery power with other devices.

The high refresh rate display function is included, resulting in a smoother screen experience with enhanced smoothness of scrolling and animations. The 90Hz refresh rate reduces eye strain and provides a more responsive feel, enhancing the overall visual experience. This makes the phone more enjoyable to use for everyday tasks and media consumption.
