During the operation of any smartphone, a situation may occur to each owner when the device suddenly falls. Sometimes the phone can suffer from careless carrying in jeans with narrow pockets. In the case of the iPhone 4, this situation happens often, because by modern standards it does not have highest level strength. If trouble happens, the owner has two options:

replace the glass with another one;
walking around with broken glass on the display or back panel.

Those who like to save money prefer the first option, not knowing that such an attitude towards their favorite device can cause many problems. It is quite possible to change the glass on an iPhone 4 yourself, but to do this you need to first read the instructions for performing such work, and also acquire the appropriate tools.

The cost of replacing an iPhone 4s screen can, in some cases, be half the price of a fully functional device. Despite the fact that the iPhone 4 and iPhone 4s are almost identical in appearance, it will not be possible to switch from one phone to another. The reason is simple - contact mismatch. If parts are missing from store shelves, you should make your purchase online. You will also need the appropriate tools.

Pay attention! When purchasing tools, you need to select them specifically for the regular “four”. The fact is that the “S” generation changed the configuration of fasteners.

List of required tools

To fully complete the glass replacement work for iPhone 4, you will need the following tools:

small Phillips screwdriver;
special Pentalobe screwdriver;
plastic spatula;
a thin screwdriver with a flat blade.

Of course, the main tool that facilitates prompt and high-quality repairs is accuracy. There is no need to rush, because the procedure has its own specifics.

Instructions for self-replacement

Below we suggest that you familiarize yourself with all the stages of replacing glass with your own hands on the fourth series of iPhone.

After completing all twenty steps indicated above, you can completely replace the glass on the iPhone 4. All that remains is to install a new whole part, and then repeat the assembly steps in reverse order. During the assembly process, it is important to pay attention to the touchscreen and matrix cables. Make sure they fit completely into the gap without bending. The test is performed while pressing the touch panel against the body.

What consequences can an owner face when using a broken device?

It also happens that iPhone 4 owners decide not to replace the touchscreen, using the old broken one. On the one hand, the phone works, although appearance much worse than the factory one (functioning of a broken iPhone 4s touchscreen is not always possible). On the other hand, the owner risks facing a number of problems:

The picture is not displayed normally. Since a “mesh” is formed on the surface of the glass, it makes the image very difficult to see;
Loss of factory seal. Even though the fourth iPhone is not one hundred percent sealed, the surface of the touchscreen is protected from drops of water and oily substances. The presence of cracks on the surface can lead to moisture penetration inside. While walking in the rain, your smartphone may turn off completely and you will not be able to turn it on again;
brightness distortion. This defect is usually accompanied by a loss of color and picture clarity. The display itself displays information either in fragments or does not do it at all;
presence of fragments in the smartphone. During sudden movements, they can disrupt the normal operation of the phone. It is quite possible that small particles of glass touch the contacts located on the cables, causing the components through the cables of which they are connected to the motherboard to stop working normally. In addition, the sharp edges of glass can damage the delicate and sensitive skin of your fingers.

Conclusions

Replacing the touchscreen is a mandatory task that must be completed as quickly as possible. This way you can be sure that your smartphone is working properly. The replacement procedure takes more than one hour, although in capable hands the recovery time is approximately half as long. If you cannot restore the device yourself, it is recommended to seek help from service center specialists.

The iPhone 4 and its upgraded version 4s, at this point in time, have already become a legend. Users of modern versions of the iPhone remember with nostalgia the fourth version, compared to the breakdowns of the iPhone 5, that iPhone now seems very reliable. Then there were no iCloud locks of any kind, and if you forgot your password, or the sellers set it up for you in the store, you could simply reflash your phone, and it would be as good as new. But let's get to the point, how did the displays change then?

iPhone 4s screen replacement process

First of all, let’s figure out what the procedure for replacing glass on an iPhone 4s is. If you don’t want to read further or you don’t have the time and desire, then you can contact us to replace the glass on your iPhone 4 here. In fact, the display module, consisting of glass, touchscreen and display, is changing. And when they talk about a glass replacement service, they mean that the entire display assembly will be replaced, and not the glass separately.

So, we unscrew two bolts from the bottom end of the iPhone and remove the cover; it should simply slide down at the top, towards the camera. And so, we see the battery, the motherboard, and a bunch of bolts screwed into it. Now the most important thing is to unscrew all the bolts and do not forget their location, since all bolts are different. Next you will have to unscrew the same number of bolts.

After we remove the motherboard, we will need to unscrew more bolts, only this time from the frame to which the screen is attached. 6 large bolts and 4 small ones.

Then everything is simple, take the display out of the iron frame and install a new one. Now comes the hardest part, you have to screw the whole mountain of bolts back in, and if at first you were too lazy to lay out the bolts and remember which ones came from, now suffer and be tormented.

The main difficulty at that time when replacing the display on the iPhone 4 was the problem with the proximity sensors. They didn’t want to work on some screens. Most of the craftsmen agreed that the Chinese did not paint the window in the glass for the proximity sensor correctly. We had to come up with ways to eliminate such a defect, because you can’t explain to the client that you had nothing to do with it, it’s just a crap spare part. But when they call us and ask a stupid question like “do you have an original screen?”, we always answer “of course, it’s original.” There is one thing, Apple does not supply its parts to any of its services. After all, they don’t have repairs, they just give you another device and that’s it. Therefore, all spare parts that are on sale have never been and will never be original.

Don’t be naive and call different services and hope that they will tell you, yes, only we have original displays, others have a Chinese copy. Jobs himself supplies us with spare parts. Apparently these words are what customers expect when they ask about the originality of Apple parts.

Thanks to this guide, you can do it yourself. Replacing the display module will give you new glass, touch screen and LCD display. The LCD screen is glued to the glass at the factory and it is very difficult to separate them without damage. After successful replacing the display module in iPhone 4, we recommend protecting your new display from scratches, it is necessary install protective film.
