— Should I install the iOS 9.3.2 Update? —
The latest iOS is 11.2, bringing Apple Pay Cash to the iPhone (in the USA only). Bug fixes too, of course, including another weird one where the word "it" was converted to "I.T" by auto-correct. Yay! If you have an iPhone X, or any other iOS device on any other version of iOS 11, get the 11.2 update (Settings/General/Software Update).
Easy answer: yes, unless you are thinking of updating an iPad Pro 9.7 inch. In that case, don’t. The iPad Pro 9.7 inch can, in some cases, become “bricked” (completely unresponsive) when the 9.3.2 update is applied.
UPDATE:Apple has recognized the problem and for now the highest available iOS version for the iPad Pro 9.7 inch is 9.3.1. If you try to get 9.3.2 on an iPad Pro 9.7 inch you’ll be told that 9.3.1 is the highest version available. For now.
UPDATE #2: Apple has released a revised 9.3.2 for the iPad Pro 9.7 inch. They’ve included complete instructions, even addressing the “Error 56” problem.
You may be wondering what’s new in 9.3.2, compared to 9.3.1. As with most small updates it’s security improvements and bug fixes. You can read all about it on Apple’s site and it won’t take long as there are only five bug fixes listed.
I recommend you install the 9.3.2 update “over the air” which means you go to Settings, General, and Software Update. Do it when your device is plugged in (charging) and connected to WiFi.
