Though Google made significant strides in smoothing out Android performance with Project Butter, apparently it's not yet satisfied. According to L'Express, Mountain View has just purchased French firm FlexyCore for €16.9 million ($23.1 million). That company made its name with software like DroidBooster, which improves the speed of apps running Android without increasing battery drain. A Google spokesman in France said that the business is already integrated with its Android teams, and confirmed that the software will "help optimize the performance of (Android) on mobile devices." Whether it'll bear fruit in the soon to be released Android 4.4 KitKat remains to be seen -- but given Google's promise that the new OS will make even low-spec phones sing, we wouldn't be surprised.
