iPad Display Issues with Stylus: Why Copy Pens Cause Touch Problems

iPad Display Issues with Stylus: Why Copy Pens Cause Touch Problems

Lately, we’ve been seeing more and more cases where customers report that the iPad display is “not responding properly” when using a pen. At first glance, it looks like a touch issue, but after testing quite a few of these, the pattern is pretty clear. In most cases, the display is actually fine. The difference comes down to the type of pen being used. When we test with an original Apple Pencil, everything behaves as expected. You can write normally, rest your hand on the screen, and the input stays stable. No jumps, no interruptions. But when we switch to a copy pen, things change. If you only use the tip, it often works okay. The moment you rest your hand on the screen while writing, you start seeing issues. Lines break, touch becomes inconsistent, or the screen seems unresponsive. That’s usually the moment customers think the display is defective. From a repair perspective, this is where things go wrong if you’re not careful with testing. If you only test quickly with a pen—especially without resting your hand—you might miss it. If you don’t ask what pen the customer is using, you might approve an RMA that shouldn’t be one. The easiest way to avoid this is to go back to basics when testing: First, use your fingers and check the full screen If touch works fine everywhere, that already tells you a lot Then test with an original Apple Pencil (your reference) Only after that, test with a third-party pen and simulate real usage (including resting your hand) That last part is important because that’s exactly where copy pens tend to fail. It’s not the screen struggling—it’s the pen not handling palm rejection properly. We’ve also found that asking the customer one simple question upfront saves a lot of time: “Are you using an original Apple Pencil?” In many cases, that alone points you in the right direction. If there’s still doubt, ask for a short video from the customer. You can usually see immediately whether it’s a display issue or just how the pen behaves when the hand is on the screen. Key takeaway If the display works fine with touch and behaves correctly with an original pen, then it’s not a screen problem. What looks like a defect is often just the limitation of a copy pen. Catching this early means: Fewer unnecessary returns Less back-and-forth with customers A smoother repair process overall

  • IFA Berlin 2022 – Highlights of an amazing event!

    IFA Berlin 2022 – Highlights of an amazing event!

    It is difficult to summarize our experience at IFA Berlin 2022 in short words, because it involves a lot of organization, effort, brands and people. That is why, we decided to ask the ones involved first-hand, how they felt being there. In this blog post you will enjoy a compilation of real opinions of 4Phones exhibitors that were at IFA and their opinions on how this type of events impact the technological and therefore the repair industries. “After 2 years of Covid, we were lucky to have the opportunity to meet our customers at IFA. Although we are an online company, business is about personal touch and people. We find these opportunities of connecting very important. We had a successful event and are grateful that we got the chance to meet and talk with current and new customers. I want to thank the partners that were involved in the whole IFA process, our team that has worked hard to make this a reality and of course our amazing customers that took the time to visit us”. - Jurrie Christians, Managing Director, 4Phones. “My experience at IFA was quite interesting. I felt that we were able to create new contacts and possible business with customers and at the same time cement relationships with our customers who had the opportunity to visit us. The 4Phones brand also gained a lot of visibility in the market in which we operate, and possible connections to other markets. It was without a doubt a very satisfying experience both on a personal and business level and from which I think we will get a lot of return as a brand.” - Paulo Santos, Sales Manager 4Phones Portugal "After three years, in 2022, IFA once again had a face-to-face edition, it was a great experience. Technology companies, the press, and the public finally had the chance to return to the halls of the Messe Berlin Exhibition center. I want to sincerely thank all customers and partners for sharing their precious time with us at our booth, and give a special thanks to all colleagues who have worked very hard to have made this event happen. I'm looking forward to meeting you all again at IFA 2023!" - Ronnie Stevens, General Director 4Phones España. “Now as we have have the IFA held in Berlin where 4Phones has participated as an exhibitor behind us, we may for sure say that we are utmost satisfied with the number of visitors we had hosted at our stand. Besides having new customers from all over the world we had the opportunity to meet friends, solution partners and long term customers. Growth is getting tougher in the face of new market dynamics: rising consumer expectations, increasing competition, and digital demands. In the recent years, professional services businesses have experienced enormous change: buyer behavior has changed, and it has proven difficult to keep up with. However, during this time 4Phones has performed exceptionally well, growing way much faster compared to any other company in its sector. We are proud with our international team distributed to 6 countries but act as a united team.” - Mesut Sakalli, Sales Manager 4Phones Turkey. Last but not least, we would like to give a big thank you to our partners that participated and made IFA possible: Canyon, Lograr, JK Digital Displays, Forward, QC Centre, Perenio, Aeno, Prestigio and Loqed. For us at 4Phones, it was a complete privilege to be a part of this amazing event. See you again at IFA 2023!

  • How to identify and diagnose Face ID failures?

    How to identify and diagnose Face ID failures?

    One of the most common iPhone failures is a Face ID that does not work. This fault can be divided into two more common ones: in the camera module, the Dot Projector is damaged, and on the other hand, in the headset flex, there is a malfunction due to a failure of the infrared illuminator in the proximity sensor or Yogi.   The first fault corresponds to a failure in the Dot Projector and indicates the following messages on the mobile phone interface:   The device will indicate that Face ID is not active: "Face ID has been disabled. A problem has been detected with Face ID. For more information, go to settings". "Face ID is not available, try setting up Face ID later"; it also states: "A problem has been detected with the TrueDepth camera. Face ID has been disabled”. Another related failure is indicated in the interface as: "Move iPhone up and down a little" and never locates it. This could be because you have moved the front camera module out of its exact place, meaning that the thermal camera was also moved. It could also be due to quality issues from changing the screen, so be sure of this before you do this procedure.   The second fault is a bit different and corresponds to the flexor that contains the Yogi:   The iPhone tells you that Face ID cannot be recognised, in this case the device may display the message: "Face ID could not be activated on this iPhone". It may also display the same message as in the case of the first failure: "Face ID is not available. Please try to set up Face ID later". Does not recognise the whole face. After identifying from the message which error the face ID failure belongs to, you can repair it, or the dot projector contained in the front camera module or the yogi contained in the proximity sensor. Want to know how to repair iPhone Face ID? Watch the video on our YouTube channel, which explains in detail the process of repairing this failure.

  • How to calibrate your Forward Laser Machine

    How to calibrate your Forward Laser Machine

    Whether you're just starting out or it's been a while since you first used it, calibrating your Forward laser machine is critical in order to function properly. Why? Because if you don't, the laser can move millimeters off the glass and burn the chassis. How to calibrate the machine? Key to the right calibration are the crystals that come with the machine when you buy it. The first thing you have to do is to put one of these calibration crystals on top of a metal piece that also comes with the purchase, inside the machine, as if it were a cell phone; then go to "Unlock", "Carving", go to "Forward" and touch "Figures". It will start burning the crystal. When it finishes it will give you a drawing of how your machine is located in the X and Y spaces. Look at the drawing it makes on the crystal. A perfectly calibrated drawing should line up the outer frame and the inner frame. If it is not calibrated you must do it. You have to see which parameters of the machine in the X and Y spaces correspond to the drawing that the machine has made. We look for them in the following way: Settings, Center, type code 101515 and we see that it corresponds to Y: 49.450mm and X: 106.700mm. Surely your machine will give you different parameters and you will have to calibrate it following these principles we explained but using different numbers; using the result you get yourself. The next thing to do is to interpret what adjustment each axis, X and Y, needs on your own machine. This means that you need to know exactly if you should add or subtract numbers from each one of the axis. If you notice that the X-axis needs a little to the right you should add numbers and if you notice that it needs a little to the left you should subtract numbers. You should add or subtract tenths; try 0.100mm on each side. For example Y: 49.450mm - 0.100mm = 49.350mm. For example X: 106.700mm + 0.100mm = 106.800mm. We copy the result for each axis in the machine and click on “save”. Now see what it looks like and add or subtract little by little until you find the best calibration. If you want to see how to calibrate the Forward laser machine, watch our newest video in which we explain and show everything:     Purchase the Laser Forward machine here.

  • About circularity and sustainability: an interview with Jurrie Christians from 4Phones

    About circularity and sustainability: an interview with Jurrie Christians from 4Phones

    This month, the newest edition of the Dutch magazine “Circulaire It” was released, in which an interesting interview with our Managing Director, Jurrie Christians, can be found. In this interview, Jurrie mentions the importance of the repair industry in the reduction of technological waste, while explaining that 4Phones is part of a circular model where every piece sold has a complete life cycle. This means that parts don’t end up in the trash can, but sometimes are re-purchased from customers for recycling purposes with the 4Phones Buyback program. In the same article, we also get to know about Rob Wierenga from QC Centre Europe, a fulfillment company that works from China with over 80 customers worldwide. Their role in this circular business model is vital, as the impact of transportation can be one of the biggest polluters. QC’s solution to this was very smart, as they started joining orders from different companies in the same shipment, saving not only money but also helping the planet in the long run. We from 4Phones strongly believe that these small efforts are the ones that will eventually generate a real change in the future. Little by little, and with everyone contributing, we can really reduce the ecological footprint our day-to-day activities are leaving.
