Believe a lot of people had encountered such experience, malic mobile phone, hint you need a system to upgrade. This moment, a lot of users can choose refus to receive, flat perhaps ignore. But, however also a lot of users choose to upgrade, want to experience newest design.
So, it is good that the system upgrades after all? This should speak of from mobile phone version above all. Because of newest IPhone, on hardware configuration, it is very outstanding for certain, can control completely so new system, those who experience new system place is brought is fluent with stimulation.
But, for the user that exceeds 2 years to the mobile phone, replacing a system is not very good way. Because replace the system after, new function is too much, cause mobile phone card very easily to pause, bring bad use experience. So, old machine was not updated.
So, interpose at new old the machine between, generally speaking, do not upgrade to leave factory than oneself the system is two expensive the system of above of big edition date is OK. Leaving factory for instance is IOS9, so most it is good to upgrade to IOS11. But little version, it is to repair BUG commonly, won't cause an effect to function, still recommend update.
