XII-19, Sep 1, 2015 : So i have basic or very little understanding about using TWRP custom recovery wiping tools. I just want to know what would happen if i were to use advanced wipe to wipe data, system and cache (not dalvik cache). If i were to wipe them would i lose all my apps? or my system settings? or the settings within my apps? from what i can search and understand on several forums it does not wipe my actual saved storage data (photos, movies etc), but what of the others i mentioned about? i haven't found a clear answer so im asking here. i have some apps that worked fine until now, tried deleting cache and data in the app info options, reinstalling the apps and wiping my dalvik cache to re-optimise the apps and to no avail does the app work again. it just crashes as i enter these app. I just want to have a clean device with all app optimised running smooth without deleting my system settings and app settings. if it comes to worse the most trouble i could afford is having to relog into all my app accounts. so what is the best path i could take here?
