Yes, 10X is optical and beyond is digital. I believe. iPhones go up to 5X, only based upon what I've seen.
Other uses for the stylus:
Translate or zoom in imbedded text.
Mark up images with high precision.
Remotely take photos or videos from 20 ft away.
Take quick notes that you don't have to save; they are saved, automatically.
I thought the 100x zoom were digital from AI and not optical.
Still, next time need new phone it probably will be back to Samsung or a slight possibility it could be SONY. Still have a Vaio VGN-AW41XH-Q bought in 2008 or 9 functioning as fast as it did then. Windows 7 Ultimate, best Windows ever made; even today if you want to make a disk image to back your computer up and restore in Windows 11 you will use the windows 7 version of that:
The Vaio is with my little girl now.
