Why the iPhone Aftermarket Screens Have Touch Issues?

As one of the iPhone screen and small replacement parts suppliers in China, the iPhone aftermarket screen touch issue is the most common problem customers complained to us about. Well, these iPhone screen problem occurs for many reasons and some of which are repairable. Here Etrade Supply would like to analyze why the iPhone aftermarket screens have touch issues and share with you repair tips on how to avoid these problems in the description below.

Normal iPhone aftermarket screen touch issues are flickering. The newly replaced screen flickering happens because of the loose screen flex cable. Other reasons are flex adaptor or flex ribbon damage. We need to disassemble the iPhone again and check the flex cables. Make sure the flex cables are connected well. Process refer to our YouTube video about China Made iPhone LCD Screen Test. Another iPhone screen touch issue is the unresponsive screen or partly unresponsive screen. This problem is complex. New aftermarket screens unresponsive issues are seldom. Reasons for this problem may be the screen hardware or software. Most unresponsive screens are not repairable. Let’s talk about another serious touch problem of iPhone aftermarket screens, ghost touch. When we turn on the iPhone, the screen is jittering and keeps switching on interfaces. This is so-called ghost touch. Technically, this issue cannot be fixed because it relates to the problem of screen manufacture and software data compatibility. As we all know, most aftermarket iPhone screens from China are manufactured in factories of the mainland, while the touch IC, which is the core part of the screen, is supported by leading companies like Samsung or Taiwan Semiconductor. Most aftermarket iPhone screens made in China cannot meet the standard of this touch IC, that’s why the touch issue occurred. On the other hand, the iPhone aftermarket screen software is insufficient to computing the larger new iPhone drive IC software volume, that’s another reason why the screen has touch issues.

Finally, we should know the reasons why the iPhone aftermarket screens haves such touch issues so that we can avoid these problems. The simple flickering issue can be fixed by checking the flex cables and flex ribbon. As to the problem of the unresponsive screen, we should check new screen and contact to the supplier for after-sale service. Anyway, the QC to products is very important. A great iPhone screen and parts manufacturer in China would work the best on their QC process. Etrade Supply is running the iPhone screen and replacement parts business for 10 years.

Why My iPad Home Button Was Falling in After Repaired?

This time we received a repair case that our customer’s iPad Air Pro home button collapsed in the display hole after repair. Although they tore down the iPad screen and readjusted the home button times, it wasn’t solid as it was before. He was frustrated because he thought there must be a small part he had been missing inside, a small bracket or something he didn’t install when assembled the iPad. That’s why he came to us. Well, this is not a big deal.


First of all, we need to know why the iPad or iPhone home button is sunken after the screen and digitizer reassembled. The iPad home button is fixing with a spacer on the digitizer hole. It has a long flex cable ribbon, which is closely adhered beneath the digitizer. When the home button is off from the screen and digitizer, the adhesive glue will be off and so as the spacer. If we don’t apply enough adhesive glue to the home screen and the spacer, the home button will be falling in after iPad Pro 10.5 LCD screen and digitizer assembled. On the other hand, the new replaced home button must be the exact same size as the hole on the digitizer. Some of the third-party manufactured home button or the iPad screen and digitizer may have errors with the standard size. This will also cause the problem of the home button collapsed.


Next, let’s show you how to install the iPad home button onto the digitizer screen in steps. Before we install the home button, we need to clear the remaining glue from the digitizer. Apply some T7000 adhesive glue on the position of the flex cable ribbon and past the flex ribbon closely on the digitizer. Push the iPad Pro home button with flex cable ribbon on the back slightly to make sure it is flush on the screen. When the home button is fixing tightly on the screen digitizer, we will need to paste the spacer for fixing the home button. We use 10mm Tesa tape to paste on the spacer, make sure the tape is fully covered on the spacer touching face. Paste the spacer across the home button. Press the spacer slightly and make sure it is tightly fixing on the home button. We can check the home button now by gently pressing on the digitizer screen, to see if it is sunken in the hole. We can readjust the position if it is falling in. Apply a little more glue around the home button and the spacer to make sure it is fastened well on the digitizer. After these steps are finished, we can assemble the screen digitizer onto the iPad screen.


Finally, we advise our customers to tear down their iPad screen and digitizer and reassemble the home button. Follow our steps above to avoid the problem. Furthermore, we suggest our customers choose the original new iPad digitizer touch screen assembly with adhesive or the home button because some third-party manufactured iPad or iPhone parts may have errors with the original device. For consideration of this issue from our customers, Etrade Supply provides the best LCD iPad screen and digitizer. All our iPad parts are 100% tested before stock-in. Customers have no worries about the home button size errors, we guarantee.

How to Fix the iPad LCD Screen Backlight dim Issue

This is a problem our customers complain about most in our shop. Some new replaced LCD screens are dim when we turn on the iPad. The same problem has happened on iPhone screens before, and we consume the issue to be the backlight circuit problem. How could this happen to the LCD screens? Can this problem be fixed? Here we would like to discuss it with you here.


Firstly, we have to know something about an iPad or iPhone LCD screen’s composition. The LCD screen is totally consists of eight layers, but only the three layers related closely to the image forming and animation on the screen. The backlight is one of these three layers. It is an LED light panel that allows the phone screen to be seen in the dark. When this light panel fails for lighting up, you will see a very dark screen and dim images, which can only seem under strong light. The reasons why this happened are complicated. For one side, some of the low-quality LCD screens are manufactured from third-party factories. These high copy screens are not matched with the original screens on the electrical characteristics. The high copy screen requires much more electric power loss than the original screen. When the backlight circuit is overloaded, it would be damaged and not work. On the other side, damages to the iPhone or iPad screens may cause the iPad screen backlight panel to fail for lighting up after iPad LCD screen replacement.


Next, fixing the backlight circuit issue can be difficult and risky. It requires someone professional on Apple mobile device repair experience on it. Since the backlight failed for lightening could be more than one reason, the repair solutions consist of a simple filter replacement, another can require replacing the whole circuit or adding jumper wires to bypass damaged tracks. Specifics of the operation may refer to YouTube videos or google. We advise you not to try without professional guidance because these solutions are risky. Inexperienced operations may cause irreversible damages to the new screen. You may check our iPad repair guidance about iPad mini 4 screen replacement video if you have interests.


Finally, we sincerely advise our iPad and iPhone users don’t trust any “parts swapping fixing everything” from a third-party repair shop. Choose the original new LCD screens or high-quality level screens for replacement if you have to swap the original screens. All in all, we should take action for our iPad screen protection or else it will cost us a lot on repair. Besides, you may come to Etrade Supply online store for our new iPad swappable screen. Here we got iPad mini 4 LCD screen and digitizer and small parts as well. You are free to contact us if you find any replacement parts you have interests. We are glad here for help.
