The strange part is, when I go to reinstall the 3.10.x play store the tablet says that it cant install the app because there is insufficient space and wants me to uninstall apps to make room before you ask yes I did uninstall google chrome 66meg just to make sure, I also cleared all the cache and tried to reinstall the apk, also tried from terminal with su. Any ideas? Just wondering if there's might be an issue that I am m (HowTos)
