You’ll be glad to know that Nothing already puts a clear Phone (4a) case in the box, along with a screen protector from the factory. Though you’ll need a case, you won't need to buy one on day one. The biggest reason is that the main, periscope and ultra-wide cameras are in a raised pill-shaped block near the top of the back.
With no case, the phone will rest on the block when you lay it down, so the lens covers absorb the scratches and knocks. Plus, the see-through back itself shows the Glyph lights, and is too big a risk to leave outside. Don't wait for an accident to happen. Grab a case for your new phone while you still can.
Liisooka military-grade case
$11.99
This case is a top pick that fixes the clear-back vulnerability of the Phone 4a without hiding the design. It has a hard polycarbonate back that resists scratches and yellowing for a long time. Your phone's Glyph panel will always be visible and stop collecting scuffs. It also has the most ratings of any clear case that lists the 4a, by the way.
Jasonyu flip wallet case
$18.99
Experience the magnetic PU-leather flap on this case in its full potential. It shields the 6.78-inch screen in enclosed spaces. There's a TPU shell inside, two card slots, and a cash pocket. The card holder folds into a kickstand as well.
Nijiadi transparent case
$9.99
This case's rim is 1.0 mm above the camera and 0.8 mm above the screen, which keeps the phone from resting on its camera block. It also has a ring on the back that rotates, and also works as a stand for watching video in landscape.
Btstring case with magnetic car holder
$11.99
This is the only case on the list that has two layers. That is, a hard shell over a soft inner case. It also has a raised frame around both the screen and the camera. Although it does hide the phone back, it offers premium protection for your device.
Wsaurbnit matte slim protective case
$15.89
This case comes with a 9H glass screen protector and a wrist strap, and it charges wirelessly through the case. These are all the insurance you need against gravity with a heavy 205g phone.
$13.99
The faux leather grips better on this case than a glossy clear case. Under the leather is a hard plastic back and a soft silicone bumper that absorb knocks. The front edge also rises 0.5 mm above the screen to keep the glass off surfaces.
Case closed: You now know your best protection options
Every week or two, try and take your phone case off and wipe the inside along with the phone's back. Dust can get trapped between the two, and every time you grip the phone, the grit rubs against the clear back.
You may want to keep the clear case from the box as a spare, so that you can cover the phone with while your main case dries after you wash it in warm water and a drop of dish soap. These habits, though tiny, can go a long way in preserving the case and device for a long time.
