    It is a very fluid phone on a daily basis and although it limps in some aspects, it works more than enough.

    Durable and good performance

    The phone lasted a long time, it has good resistance. I have dropped it down the stairs, off the balcony, many times on the ground and once in water. The phone continues to hold up as if there were no tomorrow. It is a very nice phone and it is scratch resistant. I use it every day and its performance never fails, I have tried several video games and it is very fluid. Its connection is not bad at all, I have never had any complaints about it. But what fails is the front camera, it has a medium-low quality and when taking photos at night it is usually very blurry. Regarding the sound, it is perfect. You can increase it up to 200% and it has stereo speakers which improves the experience. I give it a 9/10 and it is the best phone I have ever had.

    The OPPO A78 is like a car that won't start: For $200, I'd expect a car, not a scooter that runs out of battery.

    My experience with the OPPO A78 has been disappointing, especially considering its 1 million Colombian pesos price tag. Despite its attractive design and nice graphical interface, the value for money is abysmal. The camera, while able to perform in specific conditions, has many limitations and the overall performance of the device is slow and frustrating. There are options on the market, such as the Xiaomi Redmi Note 10 Pro, that offer better performance and features at a lower price. In short, the OPPO A78 does not justify its cost and there are much more efficient alternatives available. Main Negatives: Limited Camera: The OPPO A78's camera is only useful for very specific situations. The front camera setup requires meticulous adjustments to obtain acceptable results. In addition, telephoto performance is poor; images have noticeable brushstrokes and, without post-processing or AI, the results are noisy and unattractive. Detail Detection: Although the camera can capture certain details, they are not enough to make a photo stand out. In bright lighting conditions, exposure balance is problematic, and flare is common. Slow Performance: The phone is noticeably slow overall. The camera, in particular, is a pain; taking a photo requires standing completely still for over 15 seconds to avoid blur. Recording video is virtually impossible, as the device constantly stutters, both in 720p and 1080p.

    Pros
    • Attractive design
    • Responsive and beautiful graphical interface
    • Some customization options although it has its limits
    Cons
    • Terrible value for money
    • Slow performance and camera issues
    • Insufficient battery life
    • Necessary improvements in video playback

    5/10 not suitable for video games

    GOOD: good camera with AI, great and powerful sound quality, high image resolution and fluid videos. REGULAR: the battery charges very quickly but discharges quickly. BAD: slow in heavy video games, poor internet connectivity and the storage seems large but runs out in 2 months

What is a Ki score?
Ki is an automatic score based on the specifications and prices of devices. It is calculated using over 200 variables to rank smartphones, tablets and other devices from best to worst.
How do we calculate the Ki?

In this case, to determine the score we evaluate 5 general aspects:

  • Design and screen
  • Hardware and performance
  • Camera
  • Connectivity
  • Battery

Once these 5 factors have been rated, we introduce the price variable. This means that any two devices with the same ratings get a different Ki score for quality vs price.

Even a device objectively worse than another may have a higher Ki score if it has a better price.

Does the Ki score change?

The Ki varies as time goes by. As new devices with better specifications enter the market the Ki score of older devices will go down, always being compensated of their decrease in price.
