As a former BlackBerry 10 user (QNX based with C++/QT native apps) that's something that annoys me endlessly about Android. How can a simple action like displaying a small, locally cached playlist take any noticeable time at all?! There is no inherent reason for building Apps in JS+HTML adding a dozen additional layers all costing precious time. Even some "native" (Java) apps seem slow at times. Also switching between apps often causes these to be effectively closed, adding startup time when reopening them (are they really that memory-hungry, why?!). I never had these problems with my BB 10 phones even though these had half the RAM (2G, current Android 4G) and way less cores (2 vs. 8). I wish they hadn't discontinued this awesome platform.
