Identifying Fake LCD
When you choose a fake it can cause DPI and resolution problems as well as color brightness. In addition to this, the workmanship is usually lower. Choosing an original iPhone 6 LCD screen is the only way you can be sure your phone will be restored to its original state. Unfortunately, there are rogue traders out there who will tell you that your iPhone 6 LCD screen is original and manufactured by Apple, but this is not always the case.
There are ways to tell that the screen is made specifically for your phone with one being by the backlight. To ensure the problem is not with the backlight itself if it is possible you should check the screen on a phone you know does not have a backlight problem.
When you purchase or have your iPhone 6 LCD screen replaced by a professional service, the best way to check that the part they have replaced is original is by the backlight. In OEM versions many people find that the backlight is dimmer than it was originally. This can be verified by checking alongside another iPhone if possible.
In some cases there is a backlight, however, the screen is unable to display images or shows lines or odd shapes which could lead you to believe the new screen has not been fitted correctly. The original parts have been created specifically for the iPhone 6, and therefore fit without touching. They are more complicated than they originally seem which is why they are generally more expensive than the generic types.
Here are some other ways as following:
1. Weight
The fake screens tend to be heavier than the original, so if you feel that your phone is heavier than it was once the screen has been replaced then this is another indicator that it is a fake.
2. Color
The actual glass should not be see-through, grey or cream in color. The original iPhone 6 LED screens only come in black.
3. Earpiece grill
The screen will also have a grille to cover the earpiece, this should be uniform to the screen your original iPhone when you first bought it. This will mean that it is made from a black mesh that is fine. If the iPhone 6 LED screens come without the grill, the grill is silver or another color other than white or the holes are large you have a fake.
4. Rainbow colors
When you clean iPhone 6 LED screens you can use a spotlight/pin light to shine on it. This should display a cross pattern of diamonds that are rainbow-colored. This is something you will not find on a fake as they are usually mass-produced quickly with the fine details that are unique to Apple left out.
5. Visible proximity sensor
There is a proximity sensor in the glass that should not usually be seen. If it is visible it should be a neutral grey color. If it is more of blue transparent color it is not an original manufactured by Apple.
6. Apple logo
The Apple logo of an original iPhone 6 LCD screen will be printed on both the flex cables and screen flex. This will be alongside a laser mark which can be located on the front camera face bracket. The cover light should show the logo when reflection is shown on the cover.
