I've a quite old version of android in my smartphone. I use whatsapp regularly, except yesterday where I had to try to update, and I couldn't do it because I don't have enough space on my smartphone. I've removed whatsapp and try the reinstallation but it doesn't work... Is there anything I can do? I read that there's probably some procedure I could try using both root privileges (that I have) and an emulated terminal.
This is not the first time that happens, usually I just remove apps that I don't use, but now I don't really know what to do.
