Hat geantwortet auf: iFixit LCD Vs. eBay LCD (iPhone 4s)I know the $25-$30 ones from ebay and tmart.com has a lot of quality problems. Out of the 4 I tried (2 from ebay sellers, 2 from tmart), the 2 from ebay failed within a day or two. One of them has a poorly manufactured connector. The 2 from tmart.com has very poor viewing angles. Color would become psychedelic with a slight tilt. I didn't have problem with a $20 new iPhone 4 LCD from ebay seller 2 years ago. But this recent purchase of $25 iPhone 4S LCDs showed a lot of problems. Certainly, the appearance of the quality seems high with the naked eye. But I could see the subtle defects in the LCD connectors under the magnifying glass that would not provide a proper contact. The LCD viewing angle problems is likely in the materials and/or assembly of the LCD itself. Anyhow, low priced aftermarkets seems to be hit and miss depending on the materials and manufacturing quality of the particular batch.
