About a month ago, OnePlus announced two budget phones in the Nord-series: the OnePlus Nord N10 5G and the Nord N100. The N10 5G has a 90Hz display and a Snapdragon 690, which supports 5G. It has 6GB of RAM in combination with 128GB of storage. The N10 5G has four cameras and a 4300mAh battery. The N100, in comparison, has a 60Hz display and a Snapdragon 460 SoC. It has 4GB RAM and 64GB of storage. The device has three cameras, while the battery capacity is 5000mAh. You can read more about it here.
Now, Oxygen Updater gives you the opportunity to download the wallpapers of the Nord N10 5G and N100, including the APK itself (where the wallpapers are stored). OneNormalUsername (an Oxygen Updater team member) extracted these wallpapers & APK from his phone. You can download the wallpapers either via Google Drive, or via Hampus Olsson's Abstruct app (he is the designer of all official OnePlus wallpapers, since the OnePlus 2).
