4 Reasons Not to Install iOS 9.3.5 & 5 Reasons You Should

Install If You Have iOS 9 Problems

iOS 9.3.5 doesn't come with any specific bug fixes but it could improve your device's performance, especially if you failed to download the iOS 9.3.4 update. 

The iOS 9.3.4 update's performance on older iPhone models was solid and iOS 9.3.5 performance appears to be very similar to iOS 9.3.4. The iOS 9.3.5 update, like the iOS 9.3.4 update before it, is extremely smooth on the iPhone 5.

We've seen a decrease in random reboots on the iPhone 6s and it also fixed an issue on the iPhone 6 where the device would randomly reboot and act like it had just installed a new update. We don't randomly get the "Hello" screen anymore. 

If you decided to pass on the iOS 9.3.2 update, you'll get its fixes baked in with iOS 9.3.5. Here's the full set of fixes that arrived with iOS 9.3.2 earlier this year:

- Fixes an issue where some Bluetooth accessories could experience audio quality issues when paired to the iPhone SE 

- Fixes an issue where looking up dictionary definitions could fail 

- Addresses an issue that prevented typing email addresses when using the Japanese Kana keyboard in Mail and Messages 

- Fixes an issue for VoiceOver users using the Alex voice, where the device switches to a different voice to announce punctuation or spaces

- Fixes an issue that prevented MDM servers from installing Custom B2B apps.

It also fixes a Game Center issue that Apple failed to include in the official change log. That issue can be seen in the video below.

If you failed to download iOS 9.3 or iOS 9.3.1, it might be a good idea to download iOS 9.3.5 because it'll come with bug fixes from those updates as well. 

The iOS 9.3 change log delivered some key bug fixes for some annoying iOS 9 problems. The list included a fix for that potentially devastating "1970 Date Bug" that emerged earlier this year.

iOS 9.3.1 arrived with a fix for a previously unknown version of the "1970 Date Bug" that could be used to remotely brick your device. 

The iOS 9.3.1 update also came with a fix for that annoying iPhone 6s battery percentage issue. That's not all either. Not even close.

You'll also want to install iOS 9.3.5 if you downloaded iOS 9.2.1 or iOS 9.3 and apps are crashing when you click links. 

The iOS 9.3 change log also featured several other bug fixes including fixes for various Enterprise issues, improvements to 3D touch when using the keyboard, and an issue where large text was unreadable in Reminders.

Here is the full list of fixes that arrived witj iOS 9.3/iOS 9.3.1. Again, iOS 9.3.5 will bring these to you if you failed to download either update:
