Hello,whenever i plug my phone into my computer to do some things like add music,etc. and i unplug my phone,all apps that i have on the internal memory won't work. When i first encountered this problem i never plugged my phone into a computer again unless it was to charge my phone so i don't remember what happens to the apps all i know is that they don't work and i have to uninstall them. is there a way to fix this?
