before install a mobile phone replacement lcd, it is important that you DRY TEST the LCD prior to fitting it into the chassis (before pressing the LCD down into the frame.)
By "Dry Testing" we mean only connecting the digitizer and LCD cables, and powering up the device without any glue, fitment and without open any protective film.
The same as connecting any flex cables, be sure that the connections sit smooth and flush to avoid damaging the flexes.
This Dry Testing process allows you to check the LCD for any faults, issues or damage such as touch screen sensitivity, lcd dead pixel, colour issue, without full fitment.
The reason why this is so important, is because most damage to the LCD occurs when pressing the LCD into the frame, and damage during fitment, and is not covered under warranty because it consider as human damage.
that why this dry test allows you to report any problems or damage, without voiding your warranty by fitting it.
if you fully install the LCD without dry test, we are unable to verified the damage occur before or after installation
below are some dry test example
