In our last blog , we discussed 2 ways to solve the problem of iPhone 11 Non-Genuiner screen warning. One is is replacing the touch screen which requires professional skills and tools, but the cost is small; The other is replacing the display screen which cost more( as display screen is more expensive than touch screen).

Future Supplier Team has been working hard to solve this problem in a simpler way. After continuous testing and experimentation, we came up with a new way to solve this problem – it is China Copy LCD which solved this problem perfectly.

The following is our test results with different quality LCD screens  (System upgrade to iOS14.4.1)

  Let’s look at the iPhone 11 first.

1. China Copy LCD （IOS 14.4.1）

After replacement for both of battery and display, at the Setting – General page, there is one ‘Important Hardware Messages‘, which is for battery.  No indication of Screen.

2. OEM Assembled/Refurbished LCD （IOS 14.4.1）

After replacement for both of battery and display, at the Setting – General page, there are two ‘Important Hardware Messages‘, one for battery and the other for display. Regardless of the battery, for the display, it shows ‘Unable to verify this phone has a genuine Apple display’

The next to verify is the iPhone 11 pro

1. China Copy LCD/ China Copy Hard & Soft OLED Display （IOS 14.4.1）

After replacement of display, at the Setting page, there is one ‘Important Hardware Messages‘ for display, but at the General page, it did not show any message about display.

2. OEM Assembled/Refurbished Display （IOS 14.4.1）

After replacement of display, at the Setting – General page, there is ‘Important Hardware Messages‘ for display, enter the General page, it shows ‘Unable to verify this phone has a genuine Apple display.’

  The last to verify is iPhone 11 pro max

Apple has published a new support document that says the iPhone 11, 11 Pro, and 11 Pro Max will present customers with a warning if the devices are unable to verify a genuine display after a screen repair job.

Many of our repair shop customers also complain this problem, No matter what types of displays, OEM original new or LCD screen, this warning makes the confusion and awkwardness to their customers. Here we would like to share a technique and a simple method on how to solve this warning.

The reason is the iPhone display screen replacement requires the manipulation of Apple authority technicians with Apple’s original parts and tools. There is a touch module on the display flex which contains the iPhone 11 system data. If we use a new replaced display and power on the phone, the touch module data cannot match with the iPhone system . That’s why the warning pop-up on the screen. What we need to do is replacing the original touch module to the new display screen.

There are two ways: One is replacing the touch screen which requires professional skills and tools, but the cost is small; The other is replacing the display screen which cost more( as display screen is more expensive than touch screen)

The way for replacing the touch screen, please click the link: https://www.youtube.com/watch?v=t5CUP38__1Q

The following is the steps for replacing the display:

1. Power off the broken iPhone and tear down the original display screen;

2. Replace the face ID module from the original display to the new iPhone display;

3. Put the new iPhone display on the table, Use the special machine to grind the module and clear the module after it is completed;

4. Clean out the black adhesive from the module with solder flux and solder wick and heat up with hot air gun;

5.Tear down the touch module from the original display, use hot air gun to blow and steel tool to pry carefully

6. Clear out the black adhesive on the module, use solder past to reball the touch module by smearing the solder on the stencil and heating with hot air gun blowing

7. Applying some solder flux on the module and heating with hot air gun; Connect the display into the iPhone after the touch module is cold down.

8.Test the new display function,the pop-up non-genuine warning disappear, all the display functions are normal. The whole procedure completed successfully.

PS: 1. As to the aftermarket(Copy) iPhone display, such as iPhone 11 LCD display screen, the touch module is different from the original display.It is impossible to proceed with the same steps above.

2. The whole steps on section one are complicated. It is manipulated under the hands of the professional technician. It does not work if we try it on our iPhone without special tools and professional guidance. Contact us if you are interested.

Recently, Some Samsung users reported that they are starting to experience an unknown error that causes black screen and restart in Samsung Galaxy S series including the Galaxy S20.

Many Samsung users shared their problems on Weibo, Chinese social media platform and some of them are facing major reboot problems. Moreover, not only old devices are affected by the problem.

The affected devices include Samsung S8/S9/ S10 and even S20 models. The screen lock problem is thought to be caused by the lunar calendar. For now, it is recommended to turn off automatic updating, set the date to another date, turn off automatic updates and wait for official repair instructions from the company.

According to the claims in some blog posts, the reason for the crashes is that the old version of the screen lock application. This app causes an error in April of the Chinese calendar. Some users claim that they experienced errors and crashes on their Samsung phones.

Of course, the reason for these problems is currently unknown. If you have started to experience such a problem on your Samsung device, our suggestions are as follows…

How to fix black screen problem on Samsung Galaxy phones?

There are two solutions to the black screen problem on Samsung Galaxy phones including S20 for now.

Solution 1

• Turn off automatic updates (turn off “automatic download over WLAN”
• Back up phone data
• Change reboot entry on desktop to May 1

Solution 2

• Restart the phone
• Press the power key twice to turn on the camera
• Open the camera settings in the upper left corner
• Pull down the notification bar to enter settings
• Find the lock screen, click it and click ‘about screen lock’, then update

In the statement made by Samsung Galaxy ‘s official Weibo account, it was stated that they received the feedback on the system problems, the cause of the error was investigated and a suitable solution will be offered as soon as possible.

LCD VS OLED?

LCD screens like those used in previous iPhones and the new iPhone 8 and 8 Plus are built on a backlight—a panel as large as the screen itself that produces a constant white light anytime the screen is on. A series of polarizers and filters are layered in front of the backlight to control the light and produce the image you see on screen. It’s been the dominant technology used in flat-panel displays for almost two decades, but keeping that backlight on draws a lot of power—and that’s a big disadvantage in a portable device.

An OLED does away with the backlight completely. Each individual pixel has a tiny amount of organic material that fluoresces when current flows, so the pixels produce light directly. It’s also possible to control brightness at a per-pixel level.

iPhone X LCD VS OLED?

1. Comparing the appearance

Comparing from the front, there is no obvious difference between high copy and OEM screen.
In terms of visual effects, high copy screen display area will be obvious green than OEM screen,
And you can easily see the “fringe”.

Comparing from the back, there’s still a big difference.

First is color difference between the camera lens coating.
Second is liquid crystal drive ic, high copy is smaller than OEM.
The last is high copy screen doesn’t have four connector contacts, which may have an impact on the signal.

2. Comparing the thickness

The high copy screen looks thicker than the OEM which will have an impact on the appearance after installation.
Through measuring, we can find that the high copy screen is about 0.6mm thicker than OEM screen. After installation, the high copy screen are thicker than OEM one too.

3. Testing brightness

OEM screen has high brightness and uniform display, while high copy screen has dark display, on the white screen interface, there are clear shadows under the edge of the corner.

4. Testing screen display color

The backlight of high copy lcd is obviously uneven and shadows appear along the edge of the screen, while OEM screen won’t.

Fortunately, 3D touch and screen touch function work well.

Comparison in material:

Taken altogether, Let’s make a contrast in function:

1.Before light up the screen, the high copy screen has obvious boundaries between display and non-display area.

2.After light up the screen, high copy screen has dark display and color distortion, The edge of the display area will have varying degrees of brightness difference.

3. When you start using it, Screen Touch and 3D Touch function work well, but the high copy screen is getting hot and touch sensitivity declines. If you are playing games just right, you will crazy.

4. As high copy LCD needs backlight, so the power consumption is faster.

5. In terms of handfeel, high copy screen is poor than original owing to screen thickness. It is more easy to appear white spots.

These conclusions are all from our testing, if you have any other different views,please comment below or contact us directly: sales@futuresupplier.com.

Recently, we have got feedback from many third-party repair shops that Apple Kills Light Sensor and Face ID Function of iPhone 8/8P/X Repaired by them, some iPhone 8 series and iPhone X have got ‘ambient light sensor not working issue’ after repairing.

From the research and analysis from REWA LAB, we found that Apple may have set up some technical barriers for repairing intentionally to prevent customers from resorting to third-party repair.

To further analyze and verify the problem, REWA LAB continues the research by restoring the phone (rewriting of underlying data on the phone) and see how it works, but the ambient light sensor still cannot work. The final results are as follows: 

Based on these tests, it can be confirmed that in the absence of ID code matching mechanism, even though the whole repairing process goes with OEM display or cable on iPhone 8/X, third-party repair can also cause ambient light sensor not working issue.

Judging by this, Recore finds new way to repair iPhone 8/8 Plus/X, fortunately the result shows Light Sensor and Face ID Function are OK after repaired.

According to MacRumors’s report, news of a previously-unknown iPhone unlocking device called GrayKey surfaced, and today, MalwareBytes shared photos and additional information about the product, which is designed for law enforcement officials.

It is said that GrayKey is a small, portable gray box equipped with dual Lightning cables. Created by a company named Grayshift.

Two iPhones can be connected to the GrayKey at once, and need to be connected for about two minutes to install proprietary software that’s designed to guess the passcode for an iPhone. Once the software is installed, it will work to crack the passcode, a process that can take as little as a few hours for a short passcode or several days for a longer six-digit passcode.

Once the GrayKey software has cracked the passcode, it’ll be displayed right on the screen of the iPhone. The iPhone can then be plugged back into the GrayKey to download all of the data on the iPhone, including the unencrypted contents of the Keychain, which can then be accessed using a computer.

Based on screenshots, the GrayKey can crack modern iPhones running modern versions of iOS. It works with the iPhone X and iOS 11.2.5, the version of iOS that was likely available when the screenshots were captured. It probably also works with iOS 11.2.6, unless Apple has managed to block it in the latest operating system update.

Grayshift presumably designed the GrayKey for law enforcement professionals, and it’s relatively expensive. A $15,000 option requires internet connectivity and is geofenced to a specific location once set up, while a $30,000 option requires no internet connection and can be used anywhere.

MalwareBytes worries that the portable version of the GrayKey could easily fall into the wrong hands. It uses two-factor authentication, but given that people “often write passwords on stickies and put them on their monitors,” it’s possible the token could be kept in the same location as the device.

How the GrayKey works is not known, but it’s believed to be using some sort of jailbreaking process that could damage iPhones in some way. It’s also not known how the GrayKey device itself is protecting data that’s stored on it, and whether or not the data could be remotely accessed by hackers.

Apple is continually working to fix the kinds of exploits used by devices like the GrayKey, so it’s possible whatever mechanism the box uses will be fixed in a future update. The average iPhone owner likely doesn’t need to worry about the GrayKey, but as MalwareBytes points out, it is troublesome knowing such a device could fall into the hands of malicious entities.

One of the most common misconceptions we see in the iPhone repair business is the true meaning and understanding of the definition of OEM Refurbished LCD Screens and OEM Assembled LCD Screens. Now Let’s distinguish them step by step.

First of all, we need to know the process of manufacture.

OEM Refurbished LCD screen

1. Raw material source： broken glass but with good lcd and flex cable

2. Remove the broken glass by professional equipment;

3. Test the function of lcd screen, ensure the lcd works well;

4. Clean the LCD Screen and test it again;

5. Laminating LCD Screen with New glass lens with Frame pre-installed;

6. Test the function after finishing the lamination.

OEM Assembled LCD screen

1. Raw material source： broken glass or flex cable but with good lcd;

2. Remove the broken glass or flex cable by professional equipment;

3. Assembling the flex cable to the LCD Screen (Very important);

4. Test the function of lcd screen, ensure the lcd works well;

5. Laminating LCD Screen with New glass lens with Frame pre-installed;

6. Test the function after finishing the lamination.

Secondly, let’s see the difference.

In the process of OEM Refurbished, We must understand the focus: only glass lens is replaced, the lcd and flex cable is original. So the function of lcd assembly is stable just like original one.

While the OEM Assembled lcd needs to reassemble flex cable which is hard to operate and control, so the function is not steady.

Finally, You get what you pay for.

We Future Supplier always offer OEM Refurbished lcd screen assembly.To a large extent can avoid the instability problem.  We also analyse the instability of OEM Assembled lcd assembly such as no touch, Intermittent without touch, Screen display is prone to lines or black screen. These problems have a great relationship to the assembling flex cable.

So if you want to buy the cheapest LCD screen from your supplier, be careful for these problems.

Recently, we have heard a lot of rumors about refurbishing iPhone 6 to iPhone 7.
But whether it is true or not, we can analyze it from phone structure.

First let’s check the structure of iPhone 6:

The structure of iPhone 7:

LCD Assembly Components:
Backlight/Display Module/Display Driver IC/Flex cable/glass lens/frame

The similarity:
1. LCD Display Module: 4.7 inches
The basis of refurbishing and recycling.

2. The differences: Backlight/Flex cable/Driver IC(data difference)/Glass Lens/Frame

Backlight difference:

Flex Cable difference:

Driver IC difference: If refurbishing iPhone 7, you need reinstall driver IC.

Glass lens difference:

If it is available for converting iPhone 6 to iPhone 7, we need the following spare parts.

1. Open Module parts: iPhone 7 Flex cable/Glass Lens/Frame/Backlight
2. Valuable Parts of old LCD: Gravity sensor flex cable of Backlight/ Driver IC/ Good LCD

Problems:
The compatibility of Display Drive, which may lead to functionality unstable, No display and touch function after your iPhone upgrades to the newest version, and the problems will not appear at once until you used one to two weeks.

There are no free lunches in life, if you get cheap spare parts, then you need to take higher risk.

Distinguish:

1. If Driver Module is not original, the display resolution will be different, LCD Display will also have color distortions.
2. The glass lens and frame are produced by open mold, it may appear installation problems.

All in all, No matter it is available for refurbishing iPhone 7, we need to have the right attitude, just believe: you get what you pay for, the higher the price, the better the quality.

From Etradesupply’s What you should know about replacing screen parts!, we know the basic ways to tell which parts (front glass lens, digitizer, LCD)are broken. Let’s review it again.

If you’ve damaged your front glass only, then the touch and display function will not be effected except for several cracks or scratches on your cellphone display, and that sounds like a lucky thing for you compared to other situations.

If the touchscreen broken, you’ll lose the touch function, but you could still see what is happening on the screen, and the screen should still function as normal.

When the LCD is broken, the panel will have dark blobs or spider web-looking cracks (or both). And maybe can no longer see anything on the screen. It can be verified if the screen has lines within it, or if it has a “spilled ink” look.

We can judge some problems from the appearance, but for more detailed information, we need to test the LCD screen. So the process for judging more issues is as following:

1. Sight: Look at the appearance, check the outline is good or not.

2. Test: if the glass is good, we need to test the touch function and tear the backlight for ensuring the LCD Function.  If the glass is broken and see “spilled ink” , we can judge preliminary there is something wrong with the LCD, and test for more result.

3. Solution: From the above steps, we can judge which parts are wrong and get the solutions.

If the problem is in the glass, that’s simple to solve, just get a new glass and the phone can work again.

If the issues are on the touchscreen, pure change a new one is not realistic, Future Supplier can help you to refurbish, and you only need to pay for the processing fees. (Note: if your broken LCD is iPhone 6/6 Plus, we can convert it into iPhone 6S/6S Plus for you.)

If you find it is the problem of the LCD, you need to consider to get a new LCD Assembly, but the broken LCD can send to Future Supplier for recycling.

Furthermore, we need to know the structure difference between OEM and Copy LCD, As following picture:

OEM LCD adopts In-cell technology, the touch sensor and glass is separate, even if the glass is broken, the touch function is not affected, that’s why the phone still work though the screen cracked.

Copy LCD adopts on-cell technology, the touch sensor and glass are stick together, if the glass is cracked, and touch function is affected.

Generally Speaking, pay attention and take care of your phone, no matter what technology the lcd adopts, you can not fall down the phone frequently. If it happens, Don’t panic. This article can help you and contact us: sales@futuresupplier.com.

As we all know, the technology for refurbishing LCD screen of Samsung Galaxy S7 Edge is mature slowly, and the lcd assembly with front housing is more secure for repair shop and individual.

In recently, we find new ways to dismantle front housing of S7 Edge from LCD screen, and the LCD works well after dismantled the frame, the way is suitable for S6 Edge & S6 Edge Plus too.

First of all, we have to know the tools we need for dismantling front housing.

As following: LCD Vacuum Separator, Molly Wire, Naphtha, 0.08mm Plug Gage, OCA Film.

The detailed process are 7-step:

1. Soaking into Naphtha: Put the lcd screen with frame into the naphtha, the soaking time about 30 minutes. It is necessary step and ensure enough time for soaking.

2. Put on LCD Vacuum Separator: After soaking naphtha, we need to put the lcd with frame on the lcd separator which has rubber mat with holes, to ensure the lcd screen is fixed by the machine and the temperature of lcd separator is usually 70~80℃.

3. Insert the plug gage: the thickness is 0.08mm, which is flexible and soft. Insert the plug gage from the gap of the lcd slowly. Take good care of the flex cable in case of the damage in the process.

4. Insert the molly wire: pass the molly wire through the hole of plug gage, and insert into the gap of the lcd, then keep cutting the adhesive.

5. Remove the adhesive: use the molly wire cutting from middle to edge.

6. Insert OCA Film: use a hard film to cut the adhesive on both sides, here we choose OCA Film.

7. Test function: After dismantling the front housing, we should test the function first, and the lcd works well.

From the above seven-step, dismantling the front housing is finished, if your refurbishing equipment is complete, just do as the instructions. Any question, please contact us: sales@futuresupplier.
