The Tecno Pouvoir 3 Plus comes with a 6.35-inch waterdrop notch AMOLED display with 64GB/4GB memory and runs the HiOS based Android 9 OS out of the box. While the device will continue to receive security updates for a year or two, it will not be getting an OS upgrade.

Although Tecno devices are great, not having OS upgrades is why many of the Tecno and Infinix fans have moved to brands like Xiaomi, Oppo, Samsung etc. I’d say the company really care for its fans.
