I had a chance to use the Lenovo Tab 4 8+ yesterday in an uncharacteristically bright sunny May afternoon in the UK, and had no real problems seeing the screen data. Obviously, it isn't perfect and once or twice, i felt the need to shade it a little, but it certainly suits my needs as a leisure user. I found that using the grip mount I mentioned earlier lessens the glare on screen a little, purely because you can tweak the angle better., compared to holding the tablet in the grips, but that would be the same for any tablet.
