Have you ever wondered what the inside of a smartphone looks like or what makes it tick? A smartphone is pretty much just a miniaturized computer that you carry around in your pocket. Most smartphones are quite complex devices and as they become thinner and more lightweight, many of these devices are held together by industrial strength adhesives. These adhesives make fixing smartphones a difficult process and one of the main reasons, besides the cost of parts, that repairing smartphones is so costly.

Let’s take a look inside a Samsung Galaxy Mega

From the outside a smartphone doesn’t look like much, but on the inside there are numerous parts and pieces that make these devices work.

The Frames

In the Samsung Galaxy Mega there are 2 main pieces that hold the internal pieces together. The back frame and the front frame. The front frame holds all of the important components including the digitizer, LCD screen, and motherboard.

The LCD, digitizer and front frame are all held together using industrial strength adhesive. The only way to remove this adhesive is by applying heat to the glass which loosens the adhesive allowing it to be removed from the device. Too much heat and the LCD or other parts can be damaged. Patience is key to successfully removing the glass as the LCD can be easily damaged. It is also recommended to remove the other components from the frame to avoid damage to these parts.

The Components

The components are what make the smartphone work. Components include things like the motherboard, cameras, proximity sensors, charging boards, headphone jacks, etc.
