Back in May 2018, Nokia 7 Plus devices around the world started receiving the Android Oreo V2.22A update. This update brought the improved system stability and some UI enhancements and was around 400 MB large. The similar update just showed up for TA-1046 model. It is marked as v2.22M, and also brings the improved system stability and some UI enhancements, but this time the August security patch once again. This update is also substantially smaller with just 76.7 MB in size, but the installation process took a while. The device does seem more responsive after the update was installed.
Anyway, check your Nokia 7 Plus for the update availability. Be so kind to comment your product number and country of origin so other people can save their thumbs from injuries caused by manically pressing the screen.
