I've replaced two Lumia 920 glass+digitizers 2 HTC One X glass+digitizer+LCD and one Lumia 1020 glass+digitizer+LCD. I've only ordered my screens from one place ETrade Supply|iPhone Parts|Cell Phone Parts|iPhone 4S Parts|iphone 5 parts|Mobile Phone Parts. They ship out of China but I've had no problems with the parts. The only thing I would suggest when it comes to replacing the digitizer on the Lumia 920 is that you use black adhesive. If you don't, light may leak around the edges.
Yeah I'm going to get from them. Price is not the best($53+whatever shipping) but looks like they got quality parts. Thanks
