What are the reasons for loose iPhone screen?

Hello, 1. The screen is damaged.

Solution: Whether the mobile phone screen has been dropped recently, it may cause the mobile phone screen to malfunction or the parts connected to the screen to be loose and faulty, and it should be repaired.

2. Electrostatic influence.

Static electricity can occur during screen wiping or swiping quickly, which may affect the deflection of liquid crystal molecules within the screen, resulting in horizontal streaks, screen shaking, screen flickering, or color casts. When the screen is not attached to the original protective film, the moment you quickly swipe the screen or remove the screen protector, the protective film is prone to static electricity due to material relations or dry environment, and there may be horizontal stripes, screen shaking, screen flickering or color cast. In the above cases, the phenomenon disappears when the static electricity dissipates.

Workaround: It is recommended to turn off the screen before wiping it with a clean, soft cloth or removing the screen protector.

4. Using an inferior charger to charge the mobile phone will cause battery damage, unstable battery power, and will seriously damage the touch screen.

Solution: Use the original charger of the mobile phone, if there is no or lost it is recommended to go to the official to buy.

5. System problems.

Solution: Just update the system.

6. Inferior screen.

Solution: If the boot screen shakes, and the screen returns to normal after a few minutes, you should contact the dealer as soon as possible to return it.

Extended Information: Common troubleshooting of mobile phones:

Symptom: The phone always touches the screen automatically.

1. Please long press the power to restart the phone, generally speaking, it will return to normal after restarting the phone. It may be because the phone's touch screen is affected by static electricity;

2. The mobile phone basically adopts a capacitive touch screen.

Design, when used in a humid environment or when there is moisture on the fingers, it is easy to form a conductive layer, causing the screen to drift;

3. The mobile phone screen is a precise part, if the current ambient temperature is too high or too low, it will affect the display and use of the screen. It is recommended that the screen drift in an environment where the temperature is too high or too low, and it can return to normal after waiting for a period of time in a room temperature environment;

4. It may be that the current mobile phone battery is in low-power mode, and the screen is not under the normal working voltage, which is easy to drift.

It may be a pulse flickering screen or a firmware problem with the mobile phone software, and the solution is as follows:

1. See if it's a setting problem, try to go to the phone's settings - general - restore - restore all settings.

2. The splash screen may also be caused by software problems, if it is caused by a third-party software application, try uninstalling it; If it still doesn't work, try upgrading the firmware or flashing it again.

My machine for the lower right corner to press down squeak, very annoying, because it is a buckle structure, so what hair dryer method or the like don't think, no glue at all, okay?

Tools - a five-star screwdriver (can be bought in a treasure, very cheap, or go to the repair shop to borrow it), press and hold the loose part with your hand, tighten it, it's that simple!

If you are not sure, go to the repair shop to find a professional to re-dispense.

It will lead to the following phenomena: the screen image is not clear, there are patterns flashing, or the mobile phone screen is not lit at all.

The mobile phone cable refers to the connection cable between the mobile phone motherboard and the mobile phone display, and the connection cable of the camera, button board and motherboard is also the cable.

Everything you see on the display is controlled by the motherboard, and that's where the cables come in. It is responsible for the data transfer between the motherboard and the display of the phone.

Wire maintenance principles.

When you decide to replace the cable: you must purchase *** and the same model of cable. It is convenient to buy the original cable with a seat, no welding is required, and it can be installed directly.

Buy the original cable without a seat, commonly known as the optical cable. Although the quality is good, it needs to be welded.

It is more troublesome to purchase and assemble the wire welding, which requires welding processing, and the components on the original wire are moved to the new wire, and the welding is difficult, and the maintenance manual requirements are higher.

Repair steps: First, buy a mobile phone cable that matches the phone model. Use tools to take out all the small parts of the mobile phone case, and be sure to keep them.

Re-soldering small parts to a new wire requires good welding skills, so don't try it if you don't have the tools.

After changing the cable, cut the transparent adhesive into appropriate size strips, and then use these strips to completely glue the corners of the cables, and wrap them evenly and not too thick.

Slightly loose screen squeak solution:

1. First of all, everyone takes a hair dryer and blows it on the loose place for a minute (pay attention to the wind not too hot, so as not to burn out the internal precision parts).

2. Then, everyone press the loose area with a little force (remember not to use too much force) for about two minutes.

3. Then, after pressing, you can release it and try to see if there is any abnormal sound. Generally, as long as the loosening situation is not very serious, it can be solved.

The gap is simply miserable.

Comparison with a normal phone.

It seems that Apple did not care about this detail.

I don't know if the above ** shows that it is the situation that everyone has encountered? If yes, I'd say it's really not a big deal, and it doesn't get into the dust, so don't worry too much about it. If you're "obsessive-compulsive", then let's go down and look at the structure inside, I don't have art skills, so ** is very bad, let's make do with it.

Display card slot.

Due to the convenience of everyone**, the black machine is not very obvious when shooting, so this post uses black and white mobile phones to show you.

Above**You can see the approximate internal structure of the display screen and the back shell. Except for the two screws at the tail of the phone, the entire screen and the back cover are combined by snapping, of course, I only marked the parts related to the screen cocking in this post. The upper part of the screen is mainly fixed by card slots 1 to 4.

Let's talk about the reason why the display screen is cocked.

Internal structure. Internal structure.

The above two ** can be seen that the "A" position is the main camera fixed leather pad, because of the main image here, according to the design of the space, it has caused the position of the No. 4 display card slot to be very small, can not be as firm as the number card, in addition to the camera installation reasons. The phone screen is cocked and loose. We tested a few machines, some of which solved the problem by reattaching the main image or removing the black fixed leather pad.

However, there are also some machines that are due to the slightly smaller No. 4 card slot on the screen, which causes the No. 4 card slot to be perfectly fixed, and this situation can only be solved by changing the screen. Friends with hands-on ability can try the first option, if it is a display problem, I do not recommend replacing it. Actually, please don't worry about it, because it's really not a big deal.

The "C" position on the picture is the L-shaped edge, this position fits the screen bracket, even if there are some gaps on it, in fact, it's nothing, the probability of entering the ash is really not high, you can use it with confidence.

It should be that the cable is loose, just take it to the after-sales service to help get it right. This is quite terrible for people with obsessive-compulsive disorder.

Warranty class 1 sent for repair or sent to after-sales.

There are generally two possible causes of this problem:

1. It is caused by the dislocation caused by a slight fall, as long as you gently press it in and buckle it;

Second, it is after falling, causing the loosening and gap caused by the buckle breakage, this kind of machine will lose the warranty qualification at the same time, the solution is as follows:

Use a special tool screwdriver to unscrew the two small screws at the bottom, and then, lift the panel, and glue it to the four periphery of the panel with double-sided tape (not all, only a few short sections), so as not to expose the panel, install it.

You can also use glass glue without double-sided tape, a little glass glue is fine, don't use 502, otherwise it will be difficult to disassemble in the future.

Please refer to the disassembly tutorial.

Go to after-sales repairs.

Prevent ash and water from entering;

Hello, this is a hardware problem, it is best to find after-sales maintenance.

If the motherboard and the LCD are not tightly bonded, you just need to remove it again and put on a good thin double-sided tape to re-paste it, but it is recommended to find a maintenance master to help you get it, because this is easy to break.

iPhone 6 screen loose refers to the problem of warping screen.

Note: Screen warping is one of the problems that occur in the all-in-one machine, which refers to a large gap between the outer screen and the mobile phone, and the reasons for the warping screen are as follows:

There may be omissions in the screen dispensing process in the process of manufacturing mobile phones;

Caused by overheating causing the glue to loosen or the glue is not applied properly.

The Apple 6 screen is glued to the body without screws.

That is, there is a gap between the shell and the screen, and the screen has a sense of looseness.
