This seems fairly similar in capability to the Anbernic RG351P, which uses the same RK3326 processor (and by extension the same GPU), similarly has 1GB RAM, similarly has two sticks, and similarly has a conspicuous lack of integrated Wi-Fi. Biggest difference is the screen and body: 351 has a 3.5" 480x320 screen and this is 4" 800x680.
A bunch of Powkiddy devices use this processor too, like the Powkiddy RGB10, RGB20 and V10. Reviews for any of them should tell you how well this’ll perform.
Not a phone, but probably the most mainstream example in the US market: Amazon devices often use lock screen ads by default. They charge $15-$20 more to buy a version of the device without those ads or to get them removed from an existing device. Affects both Fire HD tablets (which use a version of Android without Google services) and Kindle epaper devices (which aren’t Android).
