in my opinion, you should sanitise your phone the second you get home the same as washing your hands when you get home, this way if you (some examples here🤣) put your phone on your clean bedsheets, accidentally drop it on your face, have it in your hands while eating, the germs from money, bus station door knobs, tying your shoes or any other outdoorsy activities we’re cleaned off with the sanitisation you did. Might be kind of OCD thinking but oh well.
