I got an iPhone 7 and a 5 as company phones. Lately I can’t open excel sheets any longer!?! and on most of my frequently visited news pages videos don’t play. All software updates have regularly been applied. Beside that my iPhones also crash quite frequently. My employers with iPhones are also experiencing similar problems. I can’t say the same about Android powered devices. Luckily as a third company phone I still got an Android device. Never iPhones again!! For my family and my company I’m switching over to only Android powered devices.
