Xperia Blog- Sony Mobile has confirmed the bootloader problem that we reported on a few days back regarding the Xperia Z1. Currently, users who unlock the bootloader of the Xperia Z1 are unable to use the camera. The only way around this is to make sure you back up the TA partition (responsible for Sony’s DRM keys) prior to unlocking the bootloader and then restore as necessary, re-locking the bootloader in the process.
TechRadar - Apple has long argued for the merits of a smartphone you can use one-handed, that's why the iPhone 5S grew taller, but not wider.
The idea of a scaled down flagship isn't alien to the big Android OEMs, but Sony is the only one so far to avoid scaling down the specs when it shrank the phone, which is why the Xperia Z1 Compact is the current king of smaller Android smartphones.
HardwareZone: Miniature versions of flagship smartphones generally come with watered-down specs such as a slower, less advanced processor, less RAM and weaker imaging hardware.
The Verge:
For the longest time, the prevailing trend with mobile phones was to take last year’s handset and make it smaller. Shave a few millimeters off, shed a couple of grams, and give users the same experience but in a leaner shell. The rise of smartphones and their incessantly improving spec sheets derailed that habit, but now Sony’s returning to the old ways with its new Xperia Z1 Compact.
