My Eseries phone is often quite slow to respond after I pick it up

A. The answer is that, by default, the display rotation sensor (an accelerometer) is turned on - the idea being that you rotate the phone and the display rotates too (e.g. into landscape). All very convenient when you're consciously rotating the hardware, but what about when you simply pick your phone up off a table? In such a circumstance, the accelerometer gets hit by a barrage of g-force inputs and it takes a second or so to work out what's really going on - in that second the display might also start turning one way, then get switched back, and so on.

If this behaviour is annoying (it depends on how impatient you are and on how you pick up your phone!) then it can be turned off in 'Control panel|Settings|General|Sensors'. The response of your phone should then be as instant as it usually is, even while lifting it off a desk.

Landscape mode will still come up when needed, don't worry, with videos playing properly, or (on the E75) with the right mode appearing when you slide the qwerty keyboard out.
