The back is 2.5D mirror metallic (probably painted polycarbonate) over a similar synthetic frame.

Dual cameras sit in the middle centre with a single LED flash below. There is a rear fingerprint sensor with the MIntt OK logo are below that.

It has a pre-fitted screen protector and smallish bezels. Overall it appears well made and durable. It is a cut above the typical mass-market finish.

Screen

Size: 6.3-inch
Resolution: 1520 x [email protected]
PPI: 270
Ratio: 19:9
Type: IPS
S-T-B-R: claimed 90%
Colour depth: 16m
Brightness: Claimed – no. Measured average/peak 330/350
Contrast:  Claimed: No. Measured 1000:1
Grey-to-grey: 40+ms – a little slow for games
HDR:  No
Notch: centre waterdrop
Colour gamut: Not specified. Measured at 62% sRGB with Delta E 8.3
Colour settings: No
Screen protection: Not specified but not Gorilla Glass
Screen protector: Plastic screen protector
AOD: No
Daylight readability: Average. No glossy IPS screen is good, and while the automatic brightness tries to compensate, it is best in in-direct sunlight.
Pulse-width modulation: It uses PWM to adjust brightness which becomes evident at lower brightness levels. However, it is not an issue as you will drive this at maximum brightness.

It is a 720p screen typical of mass-market devices. Although it has reasonable brightness the automatic peak brightness favours battery life, it is not good in direct sunlight.

Colour reproduction, viewing angles, brightness and contrast ratios are average. It has a cool bluish cast that affects colours.

I strongly suspect this is not an IPS panel issue. Rather it could be fixed by a firmware update or MTK’s MiraVision – we would suggest Mintt address this in a future update.

Summary: In this price bracket, all you can expect is 720p, so it meets this paradigm.

The Helio P22 processor (2018) is often compared to Qualcomm SD430 or 450 found in mass-market devices. It uses eight lower power A53 cores in two banks – Big/Little style.

We have not seen the Helio P22 before, but it is in the Motorola E6, LG K40, Nokia 3.1 Plus, Alcatel 5V, and many more phones mainly sold it the Indian, Asian or Chinese markets.

Performance tests

The new version of Geek Bench 5 has changed ratings that appear approx. 80% lower than GeekBench4 (multiply by five).

The single/multi-core are 142/750. The Mintt UltraMintt Y3 has 276/1372, so if you need twice the power, it costs $399.

We found it quite smooth, but you will notice it slows with any CPU/GPU intensive app. We put that down to 3GB of RAM, but hey, it will still run Android 10.

It would not run GeekBench 5 Compute benchmark – we suspect this is to do with the non-standard GPU.

GPU: The PowerVR Rogue GE8320 handles a 720p screen nicely. It is most often compared to a Qualcomm Adreno 4XX but in our benchmarking it was about 30% slower on most video tasks.

Game use: The CPU/GPU is not great for games. It should support most 2D mobile games to 25fps.
