If camera quality is a top priority for you, the Samsung Galaxy Note20 offers better overall camera performance with additional features like a telephoto camera for zoomed shots, which the Asus Zenfone 9 lacks. However, the Zenfone 9 has the edge in battery life and performance with a more recent processor. The Note20 does come with a stylus, which can be valuable if you frequently take notes or draw on your device. Screen size is also a consideration; the Note20 has a larger 6.7-inch display compared to the 5.9-inch screen on the Zenfone 9, which may be preferable for media consumption or productivity tasks. On the other hand, the Zenfone 9 is more compact and might be easier to handle if you prefer smaller phones. Finally, the Note20 may be a more budget-friendly option compared to the Zenfone 9's upper midrange price. Both phones run on the Android operating system, so your choice won't be affected by a difference in software ecosystems. Give Feedback

"The Asus Zenfone 9 is a compact device that still packs more than enough power under the hood. It's compact size, Bluetooth and audio features (including a headphone jack!), and hardware gestures combine to offer a package that does enough differently to warrant your attention."

"We think pretty much anyone picking up the Note 20 to take photos will be very happy with the sharpness and appearance of the shots. If you're looking for a phone with an integrated stylus then there's little better than the note-taking potential of this phone. Sure, its 'glasstic' rear and lack of higher refrsh-rate screen are little red marks against its specification, but you can buy the step-up Ultra model if you see that as a problem - although we prefer the smaller price and smaller camera lump of this 'entry' Note model."
