Mobile smartphones really took off from the launch of the iPhone in 2007.
Prior to that, mobile phones, smart or not, were, in reality, only limited to the functions of calling and texting. So this change meant that phones went from being your electronic device to being your personal mobile computer.
That also meant that if they lag like your home desktop computer or laptop (if you still own those), you should learn to optimize them. Back in the day, we had tricks like not putting any folders on your desktop, increasing your virtual memory space, remove unnecessary background running programs, remove startup helpers.. etc. Many of which we still do need to discipline ourselves to do.
But really, if your mobile phone is dominating your HCIs, then the major time savings from this segment will come from optimizing your mobile phones.
I use a Samsung Note II and this post is biased towards that:
Speed Up from Home ButtonDouble tap the home key > Press menu > Settings > Open via home key. It will remove the delay caused by the S Voice on using the home key between apps.
Stuttering AnimationsGo to Settings > About device > Tap the build number 7 times > Go back and select Developer options > Turn off the Animations Scale options. This will disable the animation whenever you open apps on your device.
From Pencil to EraserIn order to avoid tapping the pencil or eraser back and forth using the S Pen, use the button on the S Pen itself then tap the screen to quickly shift to the other function.
Idea SketchIf you want to draw something and wanted to get some sketch provided by Note 3, hover the S Pen on the screen for a second, then press the pen's button to go straight to the Idea Sketch option.
Quick One-Hand KeysInstead of going all the way to the Settings just to make your keyboard work on one-hand operation, go to Messaging or any similar apps wherein the keys automatically pop-ups then pinch quickly on the virtual keyboard to use it for one-hand typing.
Use Other Home LaunchersSome home launchers are better than TouchWiz UI used by Samsung on Galaxy Note 3. Head to the Play Store then download third-party launchers such as Nova Launcher. It will not remove the TouchWiz UI inside the system but if use it as default, the device will use it after a reboot instead of TouchWiz.
Root AccessRooting your Galaxy Note 3 will enable you to remove the TouchWiz UI itself but the current warranty and Galaxy S exclusive apps are all going to be erased if you do this. Make sure you are completely okay living without TouchWiz.
Custom ROMAfter root access, you can use customised ROMs and replace the original firmware to free the device from bloatware such as Galaxy S apps. Custom ROMs also come with several tweaks provided by developers to make them faster than the TouchWiz running Note 3.
