    I would improve a few things but I don't regret the purchase.

    Let me start with what I find lacking. 1. The call volume on the earpiece is quite low, especially for a smartphone designed for "special tasks." 2. The sound quality on the speaker is quite poor – the treble is ear-piercing, with too much of it at the expense of the rest of the frequency range. 3. The photo quality on the main camera without the PRO settings – the photos are significantly overexposed. Only when you go into the PRO settings and set the EV parameter to -2 do they look better. 4. The LED brightness isn't terrible either. 5. The buttons should be more resistant; they're too easy to accidentally press, especially the programmable one on the left because it protrudes. 6. The sound quality on the headphone jack is also poor. Luckily, I recently switched to Bluetooth headphones. What's great in my opinion: 1. The battery!!! This smartphone sometimes lasts 5 days on my phone. It's true that I don't game on it, but I still use it quite often. 2. FM radio without headphones, IR LED, night vision. 3. A good quality thermal imaging camera, very useful in my profession - that's why I bought it. 4. Performance: The Mediatek 9300+ does the job; I don't need anything more to be happy in this regard. 5. 16GB RAM and 1TB SSD + additional SD slot. 6. Waterproof and drop-resistant, although I haven't tested the former. As for drops, it recently fell out of my pocket while getting out of the car onto the asphalt, and I found no trace of it.

    It's great for the price and very durable.

    The software is just far too basic, and the camera app lacks many options. However, it's very smooth. The battery lasts a day if you don't play Albion online for more than 3 hours on ultra settings. On the other hand, it gets hot while charging, and it gets extremely hot when playing demanding video games. For typical use—light gaming, internet browsing, and replying to messages—it's great; it lasts two days on battery. A little tip: put it in battery saver mode. It makes almost no difference, and you'll still get two to three hours of battery life. It's better to replace the battery; it just prevents Android from loading things in the background.

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.
