Will a replacement screen touch work after cracks?

There are a lot of people who assume that all replacement parts are the same and they don’t understand why some are more expensive than others (and assume greed :>). While greed certainly factors in somewhere, the reality is that the replacement screen market is highly competitive so there isn’t much room for inflated prices.

There are varying qualities of screens from aftermarket screens all the way up to OEM/Premium screens. Lower cost screens will have, you guessed it, lower quality parts, including the glass but also the flex cables, backlight, LCD construction process (hot glue vs. cold glue) etc. This has a direct impact on durability, brightness, color profile among others. You are also paying for a vendor that does thorough quality control of their parts and really stands behind them if you ever have any issues.

When you see low cost stuff on Amazon or eBay (among others), you are generally seeing the bottom of the barrel parts. These are the parts that pretty much every other major vendor has refused. Vendors do random checks of available lots and if the defect rate is higher than they'd like to see, they will pass on the lot. It doesn't mean they are all bad though and it doesn't mean there aren't any good parts in those lots.
