Looks like this update was significant, it came in at approximately 680MB from Beta 1. This may vary from device to device and depends on what firmware you are updating from. Also, you can now update your iPhone or iPad to iOS 13 or iPadOS Developer Beta 2 Over-the-Air. You just need to download the profile from Apple’s developer portal.
Apple said that the Public Beta will be coming in July, but it may come as soon as the end of June.
Here are some of the important features and changes in iOS 13 and iPadOS 13:
1. Stability: iOS 13 and iPadOS Beta 2 offers better stability and performance and we see less number of crashes in apps. Hopefully, it gets better and better in the upcoming betas.
2. Files: If you tap on the three dotted menu on the top right side of the Files App, you will see three options. One option is “Connect to Server” or SMB which is working in Beta 2 so you can now add your Network Storage to Files.
3. Camera:
a) Portrait Mode: For all iPhones having the A12 chip, you have a new option in Portrait Lighting called “High Key Light Mono” which was also announced at the event. It basically makes the background flashy-white when the background is blurred to the fullest.

c) Clearing History: When you tap on Clear History in Safari, you get four options, The last hour, Today, Today and Yesterday, and All Time. These texts were Blue in color in Beta 1 but now it has changed to Red
11. Wallpaper: When you are setting a wallpaper with iOS 13 or iPadOS 13 Beta 2, the parallax option now actually works, along with the live wallpaper option. Earlier in Beta 1, the parallax or live wallpaper icon did not function. So now you can enable/disable the parallax effect or live wallpaper.
12. 3D Touch: As we aware that iOS 13 Beta 1 had a bug in which 3D Touch completely replaced Haptic Touch on iPhones with Force Touch Displays, it seems like 3D Touch is back in Beta 2, but if we long press on an app icon, it still performs the same tasks as 3D Touch which is confusing. Are both 3D Touch and Haptic Touch working together? If yes, then Apple should remove Haptic Touch from iPhones which have 3D Touch Displays. Make sure to comment down below whether 3D Touch has been fixed for you or not. Also, The Sound feedback is a bit louder while using 3D Touch.
13. Family Sharing in Personal Hotspot: When you go to Settings>Personal Hotspot, there is a new option for Family Sharing in which you can give internet access to your family members when this is turned on.

b) When you go to the Control Centre and take a screenshot, the animation and the preview of the screenshot is behind the control center but the control center screenshot has been taken, so it should be within the control center.
