⚠️ Before disassembling, do not forget to turn your phone off.

First of all, we need to remove the card tray. To do this, we use a special tool. We insert it into the hole and carefully push out the card tray.

⚠️ If the tray does not come out well, we can additionally use tweezers.

Then we need to heat the surface of the back cover to a temperature of approximately 70 degrees Celsius or 160 degrees Fahrenheit. For this we use a heating mat, you can use a hair dryer.

And after 5 to 7 minutes, we can move on to detaching the back cover. To do this we use a thin plastic film, insert it into the gap between the back cover and the middle cover and carefully run along the edge cutting off the adhesive backing.

⚠️ As always, we need to be careful not to push the tool in too deep, so as not to damage anything that may be located under the cover.

⚠️ As we can see the back cover is separate from the camera cover.

We need to unscrew the three screws that fix the camera cover. For this we use a Phillips screwdriver of one and a half millimeters or Philips #000.

After that we need to use a non-metallic tool to detach the cover.

Carefully pry up the edge, lift and remove the camera cover.

Now we can unscrew the ten screws on the upper part. For this we also use a one and a half millimeter Phillips screwdriver or Phillips #000.

⚠️ If you see that the screws are different, they can be taken pictures or placed on a special surface where you can sign each of the screws, from where and in what sequence it was unscrewed.

Using a screwdriver Phillips 1.5 mm (PH #000), unscrew the seven screws.

So, we unscrewed all the screws and after that we need to detach the middle cover.

To do this, we use a thin tool, disconnect a few clips in the area of the card tray and then we can use a thicker tool.
