CONS
- The under-display fingerprint sensor is slower than traditional capacitive scanners.
- Uses an outdated Micro-USB port instead of the faster USB Type-C standard.
- High price point makes it compete with more powerful, flagship-tier devices.
- Funtouch OS is heavily skinned to look like iOS and lacks standard Android functionality.
- No water or dust resistance (IP rating) is present, a major omission in this price range.
- Low-light photos can be noisy, inconsistent, and suffer from a loss of detail.
- The glass back is very slippery and a major fingerprint magnet.
- The notch on the display cannot be hidden by default in the software.
- Occasional lag or stutters can be experienced during high-end, graphic-intensive gaming.
- The phone features a lot of pre-installed bloatware that takes up extra storage space.
