I could've sworn W10 wasn't supporting that until after RTM, but I can't find the article that claims that. Is that true? Also, if I goto the preview, am I forced to clear out my SD card of apps? Thanks!
U can install apps on the sd card in w10 mobile but if i were u i would rather not do that. The latest build i.e.166 has a bug which makes the apps installed on the sd card unusable after a restart. The app tiles on the start screen are greyed out and they cant be launched for quite some time. So if u upgrade to 166 then install your apps on the phone itself to avoid any inconvenience. Hope they fix this in the upcoming buildgud luck!
