I have a weird problem with my Galaxy Mega (i9205) running stock Android 4.2.2 (rooted). I noticed my memory was running out (Internal on 8 GB) so I cleared about 30-40 apps sp I got 2 GB of free memory. The weird thing is that I tried to install a license key for SD Maid (on 80 KB) and it keeps telling me I don't have enough space for it? I then tried to install Plants Vs Zombies (on 170 MB) which worked fine! I also tried to install JuiceSSH just to see if there was something wrong with SD Maid and that didn't work either! I also tried updating some apps and all apps fail to update except Snapchat. I have tried manually downloading a .apk file and installing it though both ES File Manager and Android Terminal. None of those work. Can someone help me please?
