I have a Zenithink with Android 4.2 and am constantly frustrated by the "insufficient storage" notifications when I try to download new apps from the Google Play Store and consequently having to uninstall others to make room. This is in spite of the fact that there is still 4.7 Gb of empty storage in the second internal storage area. I can't find a way to access that area and there is no option given to direct new apps to a particular area when downloading, although I can transfer those which will let me to the 32Gb external SD card. I will be eternally grateful to anyone who can help me solve this problem because it will make my tablet as useful as it should be. Otherwise I will be tempted to drop a brick on it very soon!
