For the excellent result of every repair, at ired we always carry out 24-point operation control both before and after our work.

This meticulous check ensures that the basic functions of your device have been restored and that it will work again without problems and withstand the test of time.

In particular, the 24-point Operation Control includes:

1) Check external situation.

First check the outer casing for external dents, scratches, warps, or even if the iPhone's base screws are missing.

2) Operation control touch screen and LCD.

We verify that the touch works as it should, we press and observe if the LCD has correct colours or a mark.

3) Operation control charge.

By using the ammeter we check if the device is charging correctly and raising the battery rate.

4) Operation control Wi-Fi.

Check that the device detects all available Wi-Fi networks.

5) Check rear camera.

We check if the image is clear when we open the camera and also if it is in focus.

6) Check front camera.

We check if the image is clean when we open the application.

7) Check GSM antenna.

Mobile signal strength check, carrier, IMEI - Modem Firmware.

8) Check 3G / 4G antenna.

We check the 3G & 4G data modes before we turn on the Wi-Fi.

9) Check hearing aid.

When making a call, we check that the handset has the required quality and volume.

10) Operation control microphones.

We check the main microphone and the speakerphone.

11) Operation control loudspeaker.

When making a call, we check that the speaker has the required quality and volume for the call.

12) Operation control proximity sensor.

We check if the screen automatically turns off when you approach it during a call.

13) Operation control Home button, Touch ID or Face ID.

The function of Touch ID and Face ID is important as their failure is not repaired by replacing the damaged hardware with a new one in the case of the iPhone. In android models the repair is usually possible.

14) Operation control 3D touch.  

3D touch is available on devices like iPhone 6s and newer models.

15) Operation control vibration.

We check if the vibration mechanism is working as it should.

16) Operation control mute.

Check if the device can be muted.

17) Fluctuation control volume.

Controlled via the side volume control buttons.

18) Operation control power button.

We check if the power button turns the screen on and off.

19) Operation control flash led.

We activate and check the lens.

20) Operation control headphones (hands-free).

We check that the 2 channels of the headphones, the microphone, the volume keys and the main button are working.

21) Check moisture.

If we detect signs of moisture inside the device, we inform the user and recommend chemical cleaning.

22) Check battery status.

We control the charging cycles directly and if you have more time (a few hours or a day) we can also control the rate of consumption.

23) Operation control SIM reader.

If the iPhone displays "no sim card", check if the SIM card reader works with another card.

24) Check Temperature.

We observe if the motherboard is overheating.
