Apple will switch from using TLC (triple-level cell) NAND flash to MLC (multi-level cell) NAND flash in the iPhone 6 and iPhone 6 Plus after users have crashing and boot loop issues with the higher capacity versions of both devices, . Sources have told the paper that flash memory firm Anobit, which Apple in 2011, is to blame for the manufacturing defects. Apple will reportedly switch to MLC NAND flash for the 64GB iPhone 6 and the 128GB iPhone 6 Plus, and will also address crashing and boot loop issues with the release of iOS 8.1.1. Apple previously used MLC NAND flash in previous-generation iPhones. Apple its first iOS 8.1.1 beta to developers earlier this week, although the company did not specify whether the included bug fixes addressed boot loop and crashing issues on the iPhone 6 and iPhone 6 Plus. Users who are experiencing an unusual amount of boot loops and crashes with their iPhone 6 or iPhone 6 Plus are recommended to bring their devices back to an Apple Retail Store for a replacement.
