Summary: I really wanted this product to work as the specs seem to be a good contender against Samsung Galaxy S series. It has everything you can wish for a smartphone but the hardware has serious issues. The unit I receive keeps on getting unresponsive from sleep mode after about 20 to 30 minutes of sleep.
Great while it lasted. And Sony support is garbage.

Summary: So I chat with Sony Mobile support. They have no tips or idea what may of happened, just yep it's broken, call our support line. I called the support line. On hold 15 minutes, then just silence, then it hangs up. I called back. ExCEPTionally high call volume. Press 2 to have a callback. I press 2.
Pros: Compact size for a 5" full HD display. Good camera. Well-built.
Cons: At the 10-month mark, LTE would go in and out. Then random overheating and hanging. Then it just decided to start powering itself off randomly. It only stays on if charging from wall power. Many others have reported this with the Z, ZL etc. Of course I formatted it, tried putting it back to Jelly...

Summary: Recieved the brand new phone only to find out the hard way that no micro sim inserted into the sim card slot works at all. I Get the message No Sim Card-Emergency calls only. My service provider tried every micro sim they had and none worked.
Summary: The Xperia ZL is a great piece of technology. Fast processor, excellent HD screen, reasonable battery life. Alas, for reasons unclear to me at present, the phone died within 60 days of purchase. When I say "died", please allow me to be more specific.
