Apple 2018 new iPhone rumores

Apple is rumored to be introducing three iPhones in this year: Two OLED models are known as iPhone Xs with 5.8 and 6.5 inches, and an LCD model features with 6.1-inch. All three will feature Face ID and edge-to-edge displays nearly non-existent bezels of the iPhone X, and all will be equipped with a TrueDepth camera system that supports Face ID…

The 6.1-inch iPhone features an LCD display, a single-camera, is cheaper than the other two iPhone models, and naturally costs the lowest of the three iPhone’s. The 5.8-inch and 6.5-inch iPhone, on the other hand, have an OLED display and dual cameras, and the overall design is not much different from the iPhone X, and Apple may introduce a new color match to differentiate it from the iPhone X.

The feature set of each of the three iPhones expected in 2018

In addition to Face ID and a TrueDepth camera system, all three of the new iPhones are likely to include an upgraded A12 processor, improved LTE chips from Intel (OLED models only) that will support a faster LTE connection and a USB-C to Lightning cable for faster-charging speeds. With the launch of the 5.8-inch iPhone Xs and the larger 6.5-inch iPhone Xs, rumors suggest Apple may flat out discontinue the current iPhone X rather than lowering its price tag and selling it as a lower-cost older-generation device.

Apple is planning to unveil its three new iPhones at an event set to be held at 10:00 a.m. Pacific Time on September 12 at the Steve Jobs Theater on the Apple Park campus.we can expect to see it then.

Furthermore, REWA has OEM NEW iPhone Xs Plus and iPhone Xs Power Switch Flex Cable and Ear Speakersupply, welcome customers in need of inquiries. We will help you with whatever you need.

How much do you know about OCA Film?

The brief introduction to OCA adhesive glue:
1) So far in the cell phone repair and refurbish industry and consumable material market, there are the different type of OCA glues custom made for iPhone, iPad, Samsung, LG, Motorola, Sony flagship models.
2) OCA optical clear adhesive film is also one of the important raw materials for mobile phone touch screen.
3) The OCA Tape is a highly-specialized film that offers excellent clarity, light transmitting and adhesion to a wide variety of transparent substrates. OCA Optical Adhesives are usually applied in transparent applications, such as in smartphone and tablet PC LCD displays, touch panels and other devices requiring an optically clear bond.
4) These OCA Clear Adhesive Films perfectly fit with your device and need no cutting before applying such as LG G2, G3, G4, Motorola Moto G2, G3, G, Sony Z4, Z5, Samsung Galaxy S6, S6 edge, S7, S7 edge and so forth.
5) We highly recommend professional installation. We won’t be responsible for any damages to your cellphone/mobile phone that you may cause during the replacement for your defective phones.
6) Easy to remove with no glue residue by using the special OCA Adhesive Remover.
Next let’s get a more comprehensive understanding and view of the OCA Adhesive Glue in the aspect of dimensions, property and function of different manufacturers which are Mitsubishi OCA and China Made OCA.
Function Test
1) Light Transmittance Test
The value of visible light test should greater than 90 in terms of qualified OCA glue.

2) Release Film Test
Stick the corner of the OCA protective film with easy peel/tear label to see if it can rip off easily. Mitsubishi OCA outperforms China Made in the test.

3) Adhesion Test
Stick the OCA Optical Clear Adhesive film to one clean cell phone outer glass lens to test if it has strong stickiness and is easy to tear up after fitting.

4) Laminating Test
In the course of LCD screen display laminating and outer screen glass laminating process we can easily check if the OCA can be easily laminated. There is no obvious difference between Mitsubishi OCA and China Made OCA in the effect of Laminating.

5) Bubble Removing Test
After 10 minutes bubble removing process, check the two type of phone screens. Both the Mitsubishi and China Made OCA are in good condition.

6) Bubble Returning Test
After a period of time, check the OCA to see if it has air bubbles in it. The China Made ones sometimes have small air bubbles on both sides of LCD assembly.

7) Repair Test
Separate the LCD display with the machine, then tear up the OCA glue manually to see if it can be removed easily. Mitsubishi OCA can be torn off completely by hand, while China Made OCA can not.

From the test we can draw a general conclusion: Mitsubishi OCA is better than the China Made ones in term of quality.

iPhone X Face ID not working after change screen repair tutorial

Note: This iPhone X Face ID not working after change screen repair tutorial offer by REWA. You can go to their website blog.rewatechnology.com to watch the video.

Recently we got many messages about face ID not available after screen replacement from our clients, which surprised our technicians greatly. Since the screen replacing would not affect face ID function at all according to our practical verification. However, REWA LAB has done some further researches and will share you the detailed analysis and solution for face ID failure caused by damage of flex cable after repair here.
How does face ID work?
First, let’s understand how face ID works. The whole functional area is dubbed the “TrueDepth camera system”, which is made up of flood illuminator, infrared camera, front camera, dot projector, proximity sensor, ambient light sensor, speaker and microphone. Every time you glance at your iPhone X, the flood illuminator detects your face with infrared light and forms an image. Then the dot projector will project out over 30,000 invisible infrared dots over your face to create a 3D map. Last, the infrared camera reads this map and sends the data to neural networks to create a mathematical model of your face. Your iPhone X will check that mathematical model against the one that you’ve set up and stored on your device to see if it’s a match, and if it is, it will unlock your phone.

How do we repair?
According to the description, this iPhone X was dropped once. However, the face ID is in normal status. It fails to work until a replacement of screen assembly. With all the knowledge, we begin our repair.
Power on the phone and it shows “unable to activate Face ID on this iPhone”. So we resort to resetting face ID. Go to Settings > Face ID & Passcode > Reset Face ID. We get the message “Face ID is Not Available, try setting up Face ID later”. Our initial judgment is that the unavailable Face ID might be caused by misoperation in the screen replacing process. Therefore, next thing we do is to check flex cables that are related to Face ID.

Disassemble the phone. And check the Infrared camera and dot projector module under Microscope first. Nothing goes wrong. Then move to the Flood illuminator module on the earpiece speaker assembly. Check the connector and flex cables carefully. Still, nothing goes wrong.

Then remove screws. And detach the earpiece speaker and front sensor assembly from the phone. Be careful not to damage flex cables in the process since the Flood illuminator module is bonded to glass lens with double-sided tape. We can see clearly that the flex cable where locates the Flood illuminator module is fractured at the edge.

Since the Flood illuminator module is an essential part for Face ID circuit, damage of the flex cable can result in not working of it, which can absolutely affect normal working of Face ID. Also, as flex cable repair is difficult, we can solder the Flood illuminator module to a new flex cable. To replace with a new flex cable, we need to separate the earpiece speaker and the ambient light sensor module from the earpiece speaker and front sensor assembly first. Heating with Soldering Iron, the ear speaker was separated successfully. Then, secure the flex cable in the place with High-Temperature Protective Tape for further separating the ambient light sensor module flex cable. Soldering Iron and Hot Air Gun are required to remove this flex cable. Once done, remove excess tins on the flex cable with Soldering Iron and clean with PCB Cleaner.
Now the fractured flex cable is separated completely. Next thing we do is to replace with a new flex cable. Remove the Flood illuminator module on the flex cable first. Prepare a new flex cable. Apply some Paste Flux to the bonding pad. Align the Flood illuminator module in place with the new flex cable. Be careful with the direction. Then solder with Hot Air Gun. Remove residual glue on the module afterward.

The repair part is almost over right the moment. Next thing we need to do is to re-solder the ambient light sensor module and earpiece speaker. However, the soldering of the ambient light sensor is a most difficult part for this repair. Whatever, let’s do it. Apply some Paste Flux to the bonding pad of ambient light sensor module. Then apply tins to the bonding pad with Soldering Iron. Clean with PCB Cleaner. Apply some Paste Flux to the bonding pad again. Get the detached ambient light sensor module flex cable in position. Secure the flex cable with one specific position soldered by Soldering Iron with curved nozzle first. Then use Soldering Iron with cutter nozzle to complete the remaining soldering process. Clean with PCB Cleaner afterwards. Now we need to solder the earpiece speaker back to flex cable.

It’s time to get the earpiece speaker and front sensor assembly assembled to the display assembly. Re-assemble the phone and test. Press power button to power on. Go to Settings > Face ID & Passcode > Set up Face ID. Face ID can be set up successfully. Press the power button to lock the screen. Press the power button again. The screen lights up. Glance at the iPhone X. The screen can be unlocked automatically. Fault cleared.
