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.

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.

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.

“How can other distributors have JK-In-cell screens for cheaper, while 4Phones is the official JK Digital Display brand distributor?” After research, we found out that these “cheap JK screens” are fake. In our PDF guide and YouTube video, we explain the differences and tell you how to recognize those fake screens.   DOWNLOAD OUR GUIDE: RECOGNIZE FAKE JK SCREENS     WATCH OUR DETAILED VIDEO ABOUT THE DIFFERENCES

After a long discussion, the EU recently reached an agreement: the USB Type-C will become the common charging port for all devices in the EU, regardless of their manufacturer. This means that all smartphones, tablets and cameras will contain a USB-C charging port in the future. Why a common charging port for all devices? The decision to make the USB-C type the standard charging port for all devices has advantages for consumers as well as for the environment. Nowadays, devices mostly require different chargers that are suitable for the corresponding charging port. The new rules would mean that consumers will no longer need different charger devices and cables for every new device they purchase. Cheaper and easier for consumers Consumers will be able to use just one single charger for all their small to medium-sized electronic portable devices. This makes consumers’ lives easier because it’s no longer necessary to think about the way to charge their newly bought device. The re-use of chargers will help save consumers money on unnecessary charger purchases. All in all, the new rules will expectedly save consumers €250 million a year on charger purchases. Better for the environment E-waste: you’ve probably heard of it. E-waste is electronic waste that includes any electrical or electronic equipment that’s been discarded. The waste reaches from working or broken devices to plugs, cords, electronic components and chargers. These are often thrown away and end up in places like the garbage belt. This can be dangerous due to toxic chemicals that naturally leach from the metals inside. Nowadays, disposed of and unused chargers represent approximately 11.000 tons of e-waste annually. The new common USB-C charge port law will eventually cut down on this amount of e-waste, which is great for the planet. And, other than these 2 main reasons, the new agreement will also make sure that every device supports fast charging. In addition, the law has a positive impact on technical innovation. Upcoming steps of the new USB-C port rules This new agreement has a big impact on manufacturers in the electronical industry, especially for Apple since they make use of their own company’s proprietary Lightning connector charger protocol. By autumn 2024, the new USB-C type law will go into effect. This gives manufacturers time to adjust to the new rules. The new rules apply to small to medium portable devices at first and 40 months after the law takes effect, laptops will also have to comply with the new rules. The law will not apply to products placed on the market before the date of application. How this new standard affects (y)our business The new standard will not only affect the manufacturers of devices, but also the repair industry. For instance, think of the following things: Less space in stock is needed since only 1 type of cable is required. This applies to retailers that sell cables to consumers, but also to the spareparts stock of the repair industry. There’s more room for technical innovation and specialization since the focus will be on only the USB-C type of cable. For technicians in the repair industry it will be easier to repair charging ports because only knowledge of USB-C charging ports is required.
