If camera quality is a priority, the Samsung Galaxy Note20 has a superior camera setup compared to the Samsung Galaxy A42, offering higher resolution and better performance in various conditions. However, if battery life is more important, the A42 has a larger battery, which generally means it can last longer on a single charge. The Note20 has a larger screen, which can enhance your viewing experience for media or productivity tasks, but it will come with a higher price tag. Both devices run on different versions of the Android operating system, and choosing one would ultimately hinge on balancing your preferences in camera capability, screen size, battery longevity, and budget.

Android Central

Ara Wagoner | July 2021
"I need a battery that won't care if I forget to charge it every night, and I need a nice big screen for watching my shows on the go. The 5,000mAh battery will let you get two full days out of the A42. The A42 is right up your alley as an affordable 5G phone that won't die just because you had to crash at a friend's and forgot your phone charger at home."

Mike Lowe | October 2020
"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."
