Chosen Solution

Hello everyone, I have just replaced the digitizer on my iPhone 6s and I can now see a small yellow spot in the lower left-hand side corner. I have tried every possible solution like losing the plate screws, trying removing any pressure able object under the screen but it is still there. Please help me how I can figure it out, I am also uploading an image of it.

Thanks in advance.

This is a pressure mark. If you open the screen from the bottom housing a little you will find it will disappear. Check there is nothing touching the back of the screen where the mark is showing. This can happen even if there is nothing touching the screen it can be caused from pressure elsewhere when the screen is closed. If this is the case return the screen for a refund.
