Hi there. My phone keeps saying that it has insufficient storage even though I have deleted all the data from my email app, my internet browser and everything else I can think of except the WhatsApp updates. Of a total of 129MB internal storage used, 43MB is WhatsApp, 1.49 Contacts, 0.96Phone messaging storage and 424kb is my email. The rest are items I do not even use or understand like Omacp, APK Installer, Launcher3 just to name a few. But, they all add up to about 2MB. I have no idea what is taking up the rest of the storage, but now I cannot use my email app, every time I use my browser it closes telling me to free space. I cannot even download apps like SD Maid or Clean Master because there is no space. What can I do?
