Hello all, Since a few days i have a problem that i cant reinstall an app. It downloads and when it tries to install it gives an unknown error -24. I have looked around for a possible solution but all are based on that the phone is rooted. Mine is not and do not intend to root as i dont like to risk my phone and i dont think ill use it besides this time. Also been using the phone for some time now and dont want to reinstall everything and redo all the work. Anybody have an idea how to solve this? The only thing i could find is to delete the package in data/data folder, but i dont have access to it. Factory reset is not really an option as i have to start over again too. I tried to empty the cache of playstore and delete all files but that didnt solve it. Phone is a Nexus 5 4.4.2. Thanks in advance!
