Samsung A3 How To Disassemble

How to open the lid on a Samsung Galaxy A3?

The modern mobile phone was created in order to simplify our life. In practice, however, difficulties may arise.

For example, some gadget users note that not all smartphones are convenient to use or not as advanced as their predecessors.

Therefore, this instruction will be useful to you if you do not know how to open the cover on the Samsung Galaxy A3.

After all, it becomes so unpleasant when you do not know how to open the back cover, and, as luck would have it, there is no one nearby who can tell you or help you.

But everything is not so sad, and now you will learn how in this case you need to properly handle the Samsung Galaxy A3.

Difficult task for many

If you ask the majority of users the question: How to remove the cover on the Samsung A3?, Then they will not be able to answer anything.

It seems that the developer company decided that to perform this action, we must contact the phone service centers.

In the centers, specialists will do it quickly and easily. After all, for this they have a set of special tools: a spatula (a device that disconnects the mounts) and a Phillips screwdriver.

But what if you do not have the opportunity to contact specialists or you simply do not have enough time to visit the service center? Only one way out to remove the back cover from the Galaxy A3.

How it’s done

It is important not to use brute force when disassembling a smartphone. Otherwise, it can lead to negative consequences: most likely, the smartphone will not perform its functions.

Also, dents, scratches or other damage may appear on the device case, interfering with its normal operation and pretty spoiling the appearance.

Therefore, disassembling the Samsung A3, strictly adhere to the instructions below.

Find where the speaker of your smartphone is.

  • You will see a small notch (crack) above the speaker (from the end). With its help, the cover is removed.
  • Do not lift the cover up suddenly, otherwise you may damage the back panel. You can just push it up with your fingernail and gently pull it away from the device. You shouldn’t worry, it won’t break. Never use sharp objects!

The back cover is open!

How to open the cover of Samsung Galaxy A3 and Galaxy A3 mini

To open the lid, specialists, in addition to the above tools, use a specialized hair dryer to warm it up.

It is quite difficult to do such a procedure at home. After all, you have to warm up the edges around the perimeter in the smartphone.

The phone is monolithic, so it is important to warm it up at a temperature of no more than 150 degrees (use a regular hair dryer for this).

After warming up, it is enough to gently pry off the cover with a plastic sharpened card, snapping off the screen from the case. All access to indoor modules is open!

If your goal is to completely disassemble the phone, then you must carefully read the instructions for complete disassembly. Insert the cover too, just follow the steps in the opposite order.

If you know of any other methods on how to remove the cover from the Samsung Galaxy A3, share them in the comments. If you have any questions, ask, I will be happy to answer everything.

Tools used


First, let’s thank the fellow Chipworks for the pictures of the disassembly process. They helped a lot with disassembling the Samsung Galaxy S III phone!

Samsung A3 How To Disassemble



  • Operating system Android 4.0 Ice Cream Sandwich
  • 4.8-inch Super AMOLED display with 720 x 1280 pixels
  • Quad-core 1.4 GHz processor
  • 2100mah battery
  • 8 MP main camera and 1.9 MP front camera
  • 16, 32 or 64 GB of internal memory


The simple, sleek design of the latest Galaxy S includes a standard on / sleep button on the side of the device.

And while we’re tinkering around here, getting ready to begin disassembling the Galaxy S, he watches us through his 8-megapixel camera. To the left and right of the camera are the flash and speaker.
By the way, Galaxy S is not only watching us, but eavesdropping.


Like the Galaxy Nexus, the Samsung Galaxy S III has a replaceable battery.

3.8v 2100mAh battery includes an NFC (Near Field Communications) antenna module that is used for the S Beam wireless transmission function.

In case you’re curious, 2,100 mAh is equivalent to 7,560 coulombs of electrical charge. Unsurprisingly, this equates to a 3.8v, 7.98wh battery.

I wonder what does that mean? Sounds like Samsung is advising us to read the instructions before using the battery? Yeah


It’s time to move on to the inner details. The first two plastic modules are removed using a special spatula.
The first module is a plastic frame on the back of the case, which serves to protect the motherboard and contains a moisture indicator.

By removing this module, you can reach the speaker module, which is easy to replace.


Where to start dismantling? So many details in a small space that the eyes run up!

Let’s start with the main camera? Yes, please, let’s hook this gigantic 8MP camera and pull it out of the mount.


Now let’s remove the motherboard from the case.

After removing the motherboard, you can take a closer look at the inner frame. While we suspect the frame is made of magnesium, we have no concrete evidence yet.

We found a chip not installed on the motherboard: a Melfas 8PL533 touch sensor that converts touches to ones and zeroes.


On the front side of the motherboard are:

  • Wifi module Murata M2322007 (circled in red)
  • Samsung Exynos 4412 quad-core ARM Cortex-A9 processor with 1GB LP DDR2 Green Memory (K3PE7E700M-XGC2) (orange circled)
  • Nand Flash Samsung KMVTU000LM eMMC (16 GB) MDDR (64 MB) (circled in yellow)
  • Intel Wireless PMB9811X Gold Baseband Processor (Turquoise Outlined)
  • Ics MAX77693 and MAX77686 (circled in blue)
  • Broadcom BCM47511 Monolithic GNSS Navigation Receiver (Pink Outlined)
  • 33odc 2214 4TP AC IC (black outlined)


On the back of the motherboard are:

  • Wolfson Microelectronics WM1811 stereo audio codec (circled in red).
  • Skyworks SKY77604 Multiband Power Amplifier (Orange Outlined).
  • Silicon Image 9244 MHL Low Energy Transmitter (Blue Outline).
  • Nfc chip pNXP PN544 (circled in turquoise).
  • Infineon PMB5712 RF Transceiver (circled in yellow).


The protective glass is soldered to the display, and the display to the Galaxy S III frame.
This greatly increases the cost of replacing glass if it is accidentally broken.


A few more pictures of this gorgeous camera, including an X-ray that our colleagues took from the Chipworks website.!

According to them, a Sony BSI matrix is ​​installed in the camera. In contrast to the previous data, after the initial inspection, it was assumed that this is a new matrix, and not the one used in the iPhone 4S.

The pattern of the contact pad differs both from the IMX145 matrix of the iPhone 4S phone, and from the IMX105 matrix installed in earlier models of Samsung phones.
