The improved touch driver — to facilitate wet screen usability — on the Xperia Z3+ is just one of the enhancements hardware-wise that Sony has included in its 2015 remake/flagship. Apparently, the processor inside the phone has been improved as well, as a recently published software source code for the Xperia Z3+ refers to a certain msm8994-v2.1 chip.

We do know that the MSM8994 is the Snapdragon 810, but, apparently, Qualcomm has issued a Snapdragon 810 v2.1 version of the chip. There have been a lot of reports and bad press regarding the alleged overheating of the 810 processors (as well as the throttling going on in order to facilitate heat dissipation), and Qualcomm seems to have made a new revision of the chip. If the source code is any indication, the Xperia Z3+ (as well as the Xperia Z4 Tablet) is indeed employing this new model of SoC (leaving the competition — HTC One M9, LG G Flex 2, etc — with the initial revision).

We’ll have to wait until our own Xperia Z3+ lands in our review labs in order to confirm these reports (or the benefits of a revised chip).
