Anyone else with Front Glass / LCD Panel replacement quality issues?

Hi,

I had replaced several front glass / LCD panels for the iPod Touch 4.

And i encountered this particular issue with the replacements. (I had bought them from different suppliers, eBay mostly.)

And when replacing the LCD screen + glass. And closing the device properly im getting this weird "smudge" when i press the screen. Not so hard but even with the small force applied im getting this "ghost / smudge" that clears itself after a few seconds. (Imagine when pressing a calculator display and changes color.)

Any one else having this issue?

If so, any solution?

Thanks!!

:)
