Sony’s recently-announced Xperia Z3+ may not be a worthy upgrade from the Z3 proper when it comes to the spec sheet, but perhaps there is one notable improvement that Sony made to its most recent smartphone. In a new video from GSMArena, the Xperia Z3+ and Z3 proper go head to head to see which device performs better when wet.

If you’ve ever used a smartphone when a small drop of water lands on the touchscreen, you’ve probably witnessed the user interface slightly jerk around. But after watching the video (attached below), you’ll see that the Z3+ performs significantly better than the Z3 when drenched in water. Sony accomplishes this by using a new touchscreen driver in its most recent handset that helps the device perform much better in wet conditions by using improved finger tracking technology.

In the video, you’ll quickly see that the Z3 incorrectly registers panning, zooming, multi-touch events, or no touches at all. The Z3+ on the other hand appears to have little to no problems in this scenario.

Since the Z3 is waterproof, one would expect the device to work properly when covered in water. But although the problem persists on the Z3, at least Sony made some notable improvements on the Z3+. Be sure to head to the source link below for more information on the test.
