I have an iPhone XS. The same issue has persisted for years, including now with iOS 14. The issue is: once a week (maybe - sometimes it will take several weeks to happen, once three times in a day) the following things will happen all at once on my iPhone:
WhatsApp will crash within seconds of opening, possibly related to scrolling
Twitter will not show videos or animated gifs - instead they'll be greyed out (the videos often will play, but audio only)
GPS stops working (eg Google Maps and Waze will not know where I am)
Restarting my phone fixes this. So it's a minor annoyance due to the infrequency but: what gives? I never alter any of my settings (eg location services) so am confident is not a user issue. It's survived firmware updates, app updates for years. Is it just Cursed?
