Android device owners have long been on the lookout for any signs that would confirm the arrival of an OTA update of the Android 6.0 Marshmallow mobile operating system. The firmware update, though not as major as Lollipop, promises a wide variety of new features and upgrades including a new Doze Mode, a smart standby system that is seen to bring improvements to battery life. Other upgrades include access to Android Pay, enhanced systems for fingerprint scanners, improved user experience designs and many more. The Xperia Z5 is Sony's latest flagship handset that sports a 5.2-inch IPS LCD capacitive touchscreen with 1080 x 1920 pixel resolution. The smartphone is powered by a Qualcomm MSM8994 Snapdragon 810, and has 3 GB of RAM. DxO Mark gives the Xperia Z5's camera a score of 87, one of the highest mobile photo and video scores to date. The Xperia Z4 tablet, on the other hand, is Sony's latest tablet release, and sports a 10.1-inch screen with a 2560x1600 pixel display.
