How to change the outer screen of iPhone 4:

First of all, the liquid crystal is taken out of the mobile phone, then we heat it on the separator, and then use diagonal pliers to disassemble the bracket of the mobile phone screen;

Then use a separator to cooperate with the steel wire, and the steel wire must be pulled left and right to separate the iphone7 LCD screen;

Use a soldering iron blade to cut the polarizer out of the LCD! Pay attention not to be too strong to avoid hurting the liquid crystal, especially the corners are very fragile, do not stay in one place for too long, because the soldering iron is heated, avoid burning out the backlight;

Then use a glue remover to soften the glue on the polarized light, and clean it with a dust-free cloth, taking care not to penetrate the liquid into the backlight;

Paste the dry glue and polarizer, pay attention to the glue must start from the beginning, do not fall in the middle, use the roller to paste forward in one go, to avoid blistering in the middle;

Use a special mold for positioning, and do not pinch the middle for positioning, so as to avoid that the vacuum in the middle cannot be evacuated when laminating, which will affect the effect;

Start the vacuum laminating machine for lamination;

In addition to foaming, we set it for 5 minutes, the temperature is 30 degrees at room temperature, and there are 6 or 8 pressures between the pressure screen, generally not too high pressure, or too low, too high reverse foam, too low will have a bad defoaming effect;

How do you disassemble Apple 4? Be cautious when dismantling!!

Here's a ** Oh, if you think it's good, you can adopt me:

As with the previous two generations of the iPhone 3G and 3GS, there are also two silver screws on the bottom of the iPhone 4, which are also provided by Philips, but the difference is that if you unscrew these two screws, the back case will be removed instead of the front glass. In ifixit's opinion, it may be a lot of work for you to put back the back case, but I believe that no one will disassemble their phone as a piece of entertainment.

After removing the back case, the entire inner workings of the iPhone 4 are in full view. Of course, the most conspicuous thing is the increased area of the battery. It is not difficult for us to find that the inside of the iPhone 4 is too large for the battery.

Since the iPhone 4 itself is only millimeters thick, it seems really remarkable now, and it is really worthy of Apple's design quality to be able to integrate powerful functions in such a small and slim space. It should be noted that the iPhone 4's battery connector is different from the iPhone 3G and 3GS, and the battery is not soldered to the motherboard, and the battery is also easy to remove.

It's OK to guess here, but it's really dangerous to guess again.

iPhone screen replacement cost in Chinese mainland:

It's just that the outer screen is broken, the display and touch are good, you can replace the outer glass screen alone, this is not expensive, but you must have professional instruments to remove and replace the outer glass, the maintenance fee is three or four hundred yuan, I changed it in Xi'an in July this year and received me 400 oceans, the general mobile phone repair shop can't get it, there must be a dust-free space, so as to ensure that the screen is repaired without dust; It is also necessary to automatically separate the equipment, glass and display bonding equipment.

If the outer screen is broken, and the touch or display screen is broken, then it will be sad. I can only change the assembly screen, the customer service is more than 2000, and the repair shop should be a few hundred yuan, under a thousand (I changed the glass screen directly when it was broken, so I didn't ask how much it cost to replace the assembly).

If you have spent more than 2,000 in customer service to replace the assembly screen, or if you want to continue the warranty in the customer service, you must remember to bring your broken screen and customer service back (the display and touch are normal only have the best value) to the repair shop, you can discount 100 and recover some losses.

Apple 11 restarts from time to time! It's all caused by the replacement of the glass. See how to fix the reboot.

It depends on what you are changing, the general one is about 300 fast, if it is in a specialty store, it is expected to be about 800, because it is not just the glass that is changed, but the entire screen module. After changing, the effect is almost the same.

Yes, you can go to those mobile phone repair shops, the original factory repair is very difficult, the phone will not be very sensitive after the change, the contact is slow, anyway, it is not original, the money is not very clear, it depends on the quality of the screen and the sensitivity of the touch.

Can be exchanged; However, if you only change the glass, it will not be very sensitive, which is the reason why many rear pressure screens are not easy to use, and it may be warped with it.
