Product Features & ETS Advantage
iPhone 4 Digitizer Flex Cable Ribbon is circular while 3GS Digitizer Ribbon is straight.
The iPhone 4 touch screen is available in both black and white. It includes touch screen and glass lens. They are adhered as a unit. When the touch screen needs replaced, it must be ensured that the screen can be adhered to the lcd display just like iPhone 2G LCD Assembly.
To test the touch screen is not a simple thing. We have a strict process. First we will try the dialing, sending sms and calculating function through touch. Then we will test if the gravity sensor works well. After that, we will swiftly slide with fingers on the digitizer to see lf the phone crashes. After ensuring the function is ok, we will move on to check if there is any cosmetic problem.
ETrade Supply has established the ISO9001 certified QC procedure. For each iPhone 4 touch screen, we apply strict cosmetic inspection and functionality test process before packaging and transportation. We also invent our own super-protective packaging method to give the maximum protection to the iPhone 4 digitizer touch screen. Apart from this part, ETrade Supply also supplies other replacement parts of iPhone 4 Parts.

IPhone 4 Digitizer Must Be Adhered To LCD ScreenBefore Installation. A Special Adhesive Instead Of 3M Adhesive Must Be Used To Ensure That There Is No Gap In-Between. After Installation, The iPhone 4 Screen Protector Should Better Be Used To Prevent Scratch On The Digitizer.
