Unlike regular iOS updates, there will be no automatic notification that a new version of iOS beta firmware updates is already available for download. You will have to manually check for updates to see if an update is already available. I didn't know beta 4 was already available 3 days ago until I accidentally tapped Software Update from the settings app and an option to download beta 4 is available.
On my observation, my iOS device running iOS 9.3 beta 3 has better battery management compare to previous iOS versions. There were no critical bugs that I have experienced within the two weeks of using iOS 9.3 beta 3. I only noticed one minor bug which makes the clock disappear on the home screen from time to time. To fix this, just pull down the notifications screen then the clock will go back to normal so this particular bug is not a big deal for me. Now that iOS beta 4 is released, let's see what are the new features and changes to the iOS 9.3.
Here are the three significant changes to iOS 9.3 beta 4:
1. Fixes a bug that causes 64-bit iPhones and iPads to be disabled or "bricked" when the date was set to January 1, 1970. Remember, never ever set your phone's date to January 1, 1970 because it will be disable and become unusable. Wait until iOS 9.3 becomes available or download iOS 9.3 beta 4 to avoid that bug.
2. The Night Mode icon in the Control Center was changed.
3. iOS 9.3 Beta 4 is snappier and bug the prevents the digital clock to display on the home screen is now fixed!
We are now so close to mid-March release date of iOS 9.3 so go ahead and download it to enjoy the new features iOS 9.3 has to offer!
If you already have iOS 9.3 and you want to update to iOS 9.4, simply go to
Settings > General > Software Update. Tap on "Download and Install".
