Well, since winter hit, users have noticed that their Lumias don't seem to work so well with gloves as they were supposed to. French media theWINdose heard those complaints and dug through the official Lumia spec sheets, found on Microsoft's web site, only to discover that, while older Lumias have the “Super sensitive touch” technology advertised right there, the Lumia 950 and 950 XL do not. Instead, their line reads “Touch screen technology: Capacitive multipoint-touch".
Some are speculating that the feature has been software-disabled in order to lessen battery drain in Windows 10, however, Lumia 930 owners argue that Super sensitive touch still works on their handsets, despite the fact they have upgraded to Windows 10. And, as we said earlier, Super sensitive touch is a feature achieved by the hardware construction of the display panel, not some software wizardry. It was developed by Synaptics and basically merges the screen's capacitive layer with the actual display unit, creating a number of benefits – a thinner overall display panel, more brightness for less battery power, and, of course, superior sensitivity, which can discern weaker input signals.
OK, so some tech may have been omitted from the construction of the new Lumia flagships in favor of something else – while a sad point, that's not something rare in the world consumer products. However, what's pretty bad here is that Microsoft's own Store page does list the Lumia 950 and 950 XL as having Super sensitive touch.
