iPhone 6 lcd issues

Hello guys, i need help because i cant find a answer for this. So i changed a lot of iphones screens from 3gs to 6. And now when i changing the lcd for last three iphones (2x5s and one 6) had some strange promblem. When i put all back, start testing it i saw when i push screen they have some yellow/blue marks on the same second when i push it. on the corners or near the home button. Maybe somebody know the answer? It can be for bad metal frame? Because im starting to give up.

Yellow marks tend to be due to pressure, this can usually happen if the side screws in the lcd shield are over tightened, or if the frame is misaligned causing it to have to move to the lcd shield and causing pressure.

Or it's possible that it's a low quality screen.

This can also happen with refurbished screens. :-)

Yep sometimes the iPhone housing frame needs to be bent back into place so that the screen sits flush on the iPhone housing.

Can also be due to bloated iPhone batteries, glass under the LCD shield metal plate, left over screw magnetized on the speaker.

Could dust be a possibility? Probably not.


Yes, those are also some valid points.

Dust tends to be visible due to the backlight and wouldn't really cause yellow spots though.


Yep, dust really only goes behind the backlight layer if the backlight is not adhesive on properly to the back of the screen (This is pretty popular on low quality, cheap, badly done refurbished screens especially).

Yellow spots are due to pressure on the LOCA liquid glue between the LCD and the glass / digitizer (forgot which one exactly) as the glue basically shifts and uneven pressure on the screen causes the yellow spot(s) to appear.

Correct me if I'm wrong.


Yes this is pretty spot on, it happens a lot with cheaply done and LOCA screens.

It can even happen with screens that are done properly with OCA, but is far less likely.
