If the volume buttons on your iPhone are not working,  it would be best to go to the Settings> General > accessibility and turn on the assistive touch. This option offers you control over the volume buttons, and by tapping on these options, you may have your volume buttons working fine.

If this trick not works, you may assume the problem is the internal flex cables.

First we need to know which flex cable is used to control the volume button and mute button. Yes, it is volume flex cable and WiFi flex cable.

If there is a problem with your phone’s volume button or mute key, you need to judge two parts to determine where the problem is. There are three possibilities:
1. The WiFi flex cable needs to be replaced;
2. Need to change the volume flex cable;
3. Both cables need to be replaced.

Then if we find the problem, we can reduce unnecessary cable replacement and repair time during the repair process, and reduce repair costs.

2. Disconnect and take a new WiFi cable, after connecting, please connect it to the motherboard for testing. If the function is restored, the WiFi cable needs to be replaced;
3. If you connect the new WiFi cable and the problem is not resolved, then we need to use a new volume cable to connect to the original WiFi cable and test, if the function is restored, you need to replace the volume flex cable;
4. If the new volume cable can not solve the problem, both the volume and WiFi cable need to be replaced.
5. It is recommended to proceed according to the steps we said, so that the number of screws that need to be removed is the least and the most time-saving.

What Kind of LCD Screen is Your iPhone 11?

iphone 11

Nowadays, the supply of LCD screens on the market is uneven, and it is easy to dazzle people. How to distinguish between original and imitation and how to choose the most suitable LCD screen for your mobile phone is very important. Today, let’s take iPhone 11 as an example to give you a specific introduction.

At present, the supply of iPhone 11 LCD Screens in the market is mainly divided into three types: Original, OEM refurbished and High copy.

First of all, let’s take a look at the characteristics of the original quality.

How to tell if it is the original screen?

We can distinguish from the backlight code: Original New LCDs are supplied by LG, Sharp and Toshiba, and the brand of LCD must match that of the backlight. If the LCD and the backlight do not match, the screen’s touch function will cease to work approximately two days after repair.

The code of the LCD can be found on the back of the backlight (see below).

1. LG Code: DTP & C3F
2. Sharp Code: DHK & C01
3. Toshiba Code: C11 & F7C

original glass code

We can also tell from the QR code: The long code is Toshiba glass or Sharp glass, while the square is LG glass.

These two are simple ways to distinguish the original LCD from the appearance.

Secondly, it is OEM refurbished quality.

Refurbished is divided into three types: Replacing the cover, Replacing the touch screen, and Replacing the flex cable.

1. Replacing the front cover: Only changing the front cover and frame. Other parts are still original;

2. Replacing the touch screen, there are 3 different situations;

1) Replace the original touch, only the cover and frame are imitated, the others are the original.
2) Change imitation touch; quality is divided into:  with grid and with frosted surface.

3) Change the Polarizer Film; change the original or 1:1 imitation polarizer film which can go through the sunglasses, copy polarizer film, of course failed to through the sunglasses.

3. Replacing the flex cable also have 3 different situations:

1). Original flex cable:  original touch + original flex cable + imitation cover + imitation frame;
2). Imitation cable: imitation touch + imitation flex cable + imitation cover + imitation frame;
3). It can be matched according to customer’s quality requirements.

The third is high copy quality.

It mainly includes In-cell LCD and TFT LCD.

Incell Technology make the LCD combined with Digitizer. That help to keep the Digitizer more safer inside of LCM. If the cell-phone glass been broken after dropping, the digitizer can still work well, and the Incell LCDs without Touch panel is thinner than LCDs with another piece of Touch Panel, it will be good for iPhone’s structure.

TFT LCD occupies the market of low-end models with its low price, but it has the disadvantages of hot screen and high power consumption.

Anyway,through the comparison of the above three sources, we recommend using high copy and refurbished quality. These two sources are cheap in price, stable in function and strong in compatibility.
