Cracking open the Dell Aero Android smartphone
Dell officially announced the Aero (it’s first U.S. smartphone) in March at the Spring CTIA 2010 show. By the time the phone shipped in August, expectations where running high among the tech press and Android enthusiasts. Let’s take a look under the hood to see the hardware inside.
For an in-depth look at the Aero’s features, check out CNET’s review of the Dell Aero.

The Dell Aero lacks a standard 3.5mm headphone jack. Luckily, the Aero ships with a Mini-USB to 3.5mm adapter in the box.

With the back cover removed, we can see the space for the battery, SIM card slot, and MicroSD card slot. Luckily, we can also see several Torx T5 case screws–a good sign for any cracking open job.

Removing the camera cover
Removing the camera cover
With the six case screws removed, we can begin removing the case, by gently prying loose the camera cover. It is held in place by a thin piece of adhesive tape and a single plastic tab. Using a pointed metal blade, I was able to release the tab and pry loose the cover without breaking it.

Two thin green circuits are mounted to the back of the camera cover. I’m guessing that these are antennas.

With all the Trox T5 screws removed, we can begin to gently pry the outer case away from the front panel. The case is held in place with several plastic tabs. If you’re careful, you should be able to remove it without breaking any of the tabs or the case.

I’m not 100 percent sure what this small disc is. I could be the Dell Aero’s external speaker.

A second metal disc is mounted to the bottom of the rear case panel. This could be the Aero’s vibration motor.

The display assembly is attached to the front panel and a thin silver bezel with small plastic tabs. Using a thin metal blade, a plastic case opening tool, or your fingernail, you should be able to pop the tabs loose and remove the display assembly. I recommend removing the thin outer bezel first. This will allow you to more easily access the front case panel tabs.

As I previously noted, the Dell Aero’s display measures 3.5 inch (diagonal) and has a resolution of 640 X 360 pixels. The digitizer and display are fused together into a single unit.

I wasn’t able to find any references to a Samsung chip with the specific markings 001 KAT007022M-AETT YKL033FD. Given my experience cracking open other smartphones, I assume this is a flash memory module.
