IP rating

If you're wondering whether or not your phone is water and dust resistant, you can check its IP rating.

Out of the 2021 A series phones, only the A52 has an IP rating, which is IP67. Every other model (A42, A32, A12, and A02s) does not have an IP rating; in other words, they are not water and dust resistant. Either way, you should try to keep your phone dry and use our water resistance guide to keep it running smoothly, even when it's exposed to water.

Phone cases

Along with the release of the 2021 A series comes all new cases! There are classic clear cases so you can see your phone's original color. Or, you can use the S View Wallet so you'll be able to get a quick view of your notifications and also keep important items stored in your case. Finally, there's the Xcover which will protect your phone from impacts or tough environments. You can purchase these cases separately from the Samsung website.
