Camera is not as good as the Mi 11's camera, especially in low-light conditions and when filming video.
Limited video recording capabilities (up to 4K 30fps on main camera and up to 1080p 30fps on wide-angle camera).
Average battery life may not be as efficient as other devices with similar specs.
Speakers are less impressive than the Mi 11's speakers, despite Dolby Atmos sound technology.

Oppo A3 4G

Strengths

The phone has a premium design that looks good, especially with its iPhone-like aesthetic.
It has a triple card slot, allowing for expandable storage via microSD.
The phone is said to be drop-resistant and military standard (810h), which adds an extra layer of durability.
The camera has a 50MP main sensor with a wide aperture, capable of taking decent photos in good lighting conditions.
The battery life is reportedly good, lasting up to four years with moderate use.

Weaknesses

The phone's performance is merely 'so-so', lacking the power expected from a mid-range device.
The camera performance is subpar, especially in low-light conditions and when using the front-facing camera.
The front-facing camera resolution is very bad and shaky, making it unsuitable for any type of photography beyond video chatting.
The phone's Snapdragon 6s gen one chip is reportedly a rebranded older model (Snapdragon 685), which may lead to performance issues.
The phone's price point of 9,000 pesos seems too high considering its relatively weak specs and camera capabilities compared to other options like the Infinix Hot 3 4G.
