How do you test screens before install?
As a repair shop owner, I've learned the hard way that testing screens before installation can save me a lot of headaches. I usually do a quick visual inspection first, checking for any obvious defects or scratches. Then, I set up a test environment where I connect the screen to a compatible device to ensure the display works perfectly. It really helps to have a dedicated testing phone or tablet with reliable software that can run diagnostics on the screen. I also recommend checking the touch functionality rigorously. Sometimes the display may light up fine, but the touch sensitivity can be off, which is a big deal when the device goes back to the customer. Having a good quality control checklist has been essential for my workflow, and I make sure my staff is trained to follow it every time we receive new screens.

I completely agree with the need for thorough testing! What I do is use a multi-functional testing software that not only checks the display but also the touch sensitivity, color accuracy, and dead pixels. It’s saved us from returning devices and unhappy customers. I found a great vendor that sells pre-verified screens and includes a testing report, which gives me extra peace of mind. I usually order in bulk to save on costs, and they provide a reliable warranty for the screens as well.
One thing I do differently is to use a simple app to cycle through various colors and patterns. It helps spot color issues that might not be obvious during a standard test. I also keep a log of tested screens with their results in case I have to refer back to them. It may not be as comprehensive as some of the software out there, but it’s a straightforward approach that works for me.
