The GPC reveals that the phone has a 720 x 1,600px (20:9) display and while the size isn’t explicitly listed, it should be in the same ballpark as the 6.56” HD+ IPS LCD on the Pro model (the vanilla phone measures 164 x 74 x 8mm per the FCC, roughly the same dimensions as the Pro).
The Pop 7 is powered by the Unisoc SC9863A, a chipset that was previously used in the likes of the Tecno Pop 5 LTE from 2021. It’s not a powerful chip, but it is only tasked with running Android 12 Go Edition with HiOS 12 on top.
