my xperia z tablet 16+ lte has the same issues. But it also has almost not noticeable blinking backlight when scrolling in Chrome, visible better when it's white background. It feels like slow framerate and it is really annoying.
After some testing I realized that this blinking happens through all applications. I guess backlight's is set up so in the system. It does not look hiend afterwards...
Same here only after update did the problems occur also would not charge unless turned of and not using it whenever the screen was lit it would say the battery is draining faster then its charging plug a different charger in sony helpline no use appalling customer service from them needs a big fix asap.
