This may very well be a nit-picking type of question about Android devices, and in particularly about the Samsung Galaxy SIII. The concern here, is of a UX nature. When the screen has gone blank to save the battery, and I click the power button, sometimes the screen turns on relatively quickly, othertimes more slowly. This happens also on relatively close carrying outs of such action (e.g. the screen goes blank, I press the power button, and the screen comes on quickly, then the screen goes blank to save power, I press the power button, but this time the screen comes on slowly).
The problematic usability scenario to consider is the following: sometimes, when the screen is taking longer than normal, my brain sends the signal to my hand to press the power button once more, thinking the reason the screen didn't come on is that I haven't pressed the button hard enough (especially since my phone's cover, made of plastic, makes such pressing even harder). However, as my thumb starts to press the button, but before I've completed the action, the screen comes on, and, as I complete the initiated press, the screen goes off again. So I must repeat this again. Sometimes the screen doesn't come on at all during such action because my thumb ends up finishing pressing the button just before the screen turns on, but the phone intercepts the keypress nevertheless and hence stays off. Every time this happens, I don't know if it's because the screen is taking too long to power on, if I haven't pressed the button hard enough, or if I've managed to press the button a second time just before the screen would have turned on, as a second attempt.
So my questions are:
- Why is the amount of time needed to turn the screen on not always the same?
- What's the best way to deal with the problem I described from the user's point of view?
- What about from the point of view of an electrical engineer/hardware designer7UX engineer?
- Is this problem dealt with in newer phones and fixed?
