Low storage space is a problem that gives me headache too because I use android phone for my work. The biggest headache is from "Google play service"; this app takes about 1.8 gigabit of storage space and I don't know how to deal with it. Recently, Facebook has also occupied large space; it’s over 1.5 gigabit. WhatsApp failed to work properly recently; it occupied over 1.4 gigabit. The internal memory of my phone is 32 gigabit; almost all the space is filled. I will appreciate if you guide me to free the space occupied by Google Play service, Facebook and WhatsApp; these are the biggest culprits
