It has only been a couple of weeks since I wrote about the troubles with multi-touch (well, touch in general) on the 2013 Nexus 7. At the time, Paul Wilcox of Google's Product Support forum stated that the issue was being examined, and about a week later he confirmed that the JSS15Q update addressed the problem. While many people are reporting that the OTA has completely cleared up any touchscreen glitches that had been present, some people haven't seen any improvements, and still others are complaining that the problem has grown significantly worse.
Stylus inputs for smartphones and tablets have become largely obsolete, with the exception of devices packing an integrated digitizer and active stylus, like Samsung's Note series and a few others. But some of us love our styli, as millions of cheap, plastic passive pens lining iPad accessory bargain bins across the country demonstrate. NVIDIA is hoping to boost the capability of passive stylus input on Tegra 4 hardware with its DirectStylus solution, a way for a standard capacitive touchscreen to more accurately emulate pen and paper.
