I bought my Rog Phone 7 in October last year. These already have the Android 13 system and there are no major problems with it. At the beginning of this year, Asus gave these Android 14 update and now these are full of problems and gaming is impossible even though this is a gaming phone. I got downgraded to the Android 13 system here in Finland and it works well. I still don't recommend getting any kind of phone from Asus because the technical support is non-existent and bad. They don't fix system problems, but with new updates they make existing problems worse and cause more problems. Asus technical support is the worst I've ever seen and Asus doesn't care about its customers. Don't buy an Asus phone, just avoid these.
