I managed to find something deletable, deleted it and so got some memory space freed up. So far, so good. But then WhatsApp stopped working and demanded an update. Which I tried to do, but the phone said there's not enough memory for the update. Argh, stupid phone, you're supposed to make communication easier, not harder and more frustrating! And I only just paid for continued WhatsApp usage a few days earlier. If I could afford it, I'd just buy a new phone with more memory space. Fucking fuck this fuckery.
