On occasion I will have to use 4 taps (tap tap, pause, tap tap) to wake the device. Usually after it's been locked and in sleep for a while. The power button works as usual.
This only started recently, after the 1.0.2.5 update.

Please be aware that the proximity sensor disables the touch-screen at a distance of approximately 2cm. After I investigated people's sensor issues I discovered to have one of my fingers trigger the sensor by accident every now and then. For example hitting the center of the upper half with my index finger, I trigger the sensor with my middle finger. In the center of the screen I happen to trigger with my ring finger. So this could actually be the cause of all this.
This is one of possible causes that you do not recognize when not knowing that the sensor actually gets triggered that far away. It is good to have it at such a long range for calling! Read the comments on speed and patience, please.
This constantly happens to me also by pressing the power button, without obscuring the proximity sensor.
Press to wake up screen, nothing happens, second press the screen wakes up and goes to sleep immediately after that. Sometimes the screen just gets stuck without waking up and you have to wait 5+ seconds until the device becomes responsive.
vasavr ( 2014-02-15 10:33:30 +0200 )editThat is another issue, patience and speed, sometimes it just takes a second or more till it wakes and if I don't wait (pwrbtn) it flashes and is dark again and if I double-tap slow it does not wake up at all or it seems to wake up after the third double-tap as it just took it 4 seconds to wake. These are highly subjective issues and related to performance and not really bugs, don't you think?

If the result is, that you miss a call, it is a bug – full stop (see https://together.jolla.com/question/27179/answer-call-does-not-respond-to-touch/; if this should be related).
jgr ( 2014-02-24 11:45:55 +0200 )editFor me, this is absolutely the reason (I think), because today I realized it myself. Having the Jolla lying on a office table, lying in a horizontal position and double tapping, no go.
It's because my whole damned hand is over the proximity sensor! That was really a good discovery for me. Now finally I know what that IS!

While it can never be proven 100% working, the mar14 update has fixes for the following issues
If the double tap / power key press occurred just when the device was suspending, the events were queued but ongoing suspend was not canceled. The display then turned on later, when something else caused the device to resume and allowed the events to be processed -> cause for "Once in a while it seems to take even 10 seconds or more until the screen wakes up" type issues.
A Power key press during display power up scheduled display off transition. If there was an unhandled double tap or power button press due to (1), pressing the power key press woke the device to see double tap/power key press, immediately followed by another power key press. The first one started display power up, and the 2nd one queued display power down to follow -> cause for "Press to wake up screen, nothing happens, second press the screen wakes up and goes to sleep immediately after that" type issues.

Adding to this, Power button sometimes fails to wake device, other press blinks screen and re-locks it
Bulder ( 2013-12-29 22:07:02 +0200 )editPotential duplicate of this. But that was before 1.0.2.5 so maybe not the same bug.
gukke ( 2013-12-29 22:31:05 +0200 )edit@gukke I thought it might have been but the screen does nothing whatsoever, not even turn on but stay black. I'll see what more I can find next time it happens. Whenever that is.

redge73 ( 2013-12-29 23:44:58 +0200 )editIt happens to me very often
