How to Fix the iPhone X Ear Speaker Not Working Problem

Sometimes our iPhone X ear speaker is not working and we don’t know why. We need to tear down the phone and take out the ear speaker module to check the reason. Previously we’ve demonstrated to you how to replace the iPhone X series, ear speaker. This solution works on all the mobile phone broken ear speaker issues. We don’t have to this because this time we find the ear speaker flex is broken. Here we will show you our repair steps below.

When we test this iPhone X ear speaker, we can see the ear speaker is soundless. All other functions are normal, such as the face ID recognition, the true tone, the cameras, etc. Here we assume the ear speaker must have problems. The iPhone ear speaker consists of the ear speaker and long flex cable ribbon. We need to take this module out to check the problem. Firstly, we need to turn off the phone and loosen the pentalobe screws on the bottom. Then we take the procedure of tearing down the iPhone X screen and digitizer. When the screen is removed, we unbolt the screws and take off the metal panel to take out the ear speaker module. The ear speaker seems normal. We need to measure the J4600 connector on the iPhone with the machine, we can see all the values are normal. We measure the ear speaker connector values. All are normal, too. The ear speaker has no problems, then we check the flex. Here we find a crack on the flex ribbon. This is the reason why the ear speaker not working. Base on the case, we need to solder a jumping wire aside the crack part to fix the issue. Use tweezers to scrape on the flex, on each side of the crack. Scrapping until we see the copper wire. Clear off the scrape, apply some soldering flux on the scrapes. Coat in the copper wire and solder a 0.009m jumping wire on the scrapped copper wire, jumping across the crack part. Apply some PCB cleaner to clean the crape on the flex. After the iPhone X ear speaker with flex cable ribbon is fixed, we need to install the ear speaker back to the iPhone. Tighten the screws to fix it. Assemble the screen back, connect the flex cables, and fixing the cables with a metal bracket and screws. Don’t forget to connect the battery cable. When the iPhone screen is assembled, we turn on the iPhone and check the ear speaker function. Now we can see it the ear speaker is working normally.

At last, there are some notices about the repair procedure above we need to focus on. The iPhone ear speaker flex is easy to be broken, we need to be careful on it while scraping on it.

Why the iPhone Aftermarket Screens From China 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 refers 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 the new screen and contact 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?

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.
