iOS 9.2 (Beta 1) Bug Fixes, Changes and Performance Adjustments

[TL24]

3D Touch and Multitask has definitely improved with 9.2! 3D Touch still isn't as smooth as the 6S but I'm hoping they can iron this out in the next beta.

Here's a crippling bug that requires a forced restart holding both home and power buttons:

This bug was in iOS 7.0 and fixed in 7.1. Somehow it's back and even worse than it was in 7.0.

No matter what I do, I can't reproduce on iOS 9.2 beta 1.

Well thats a bummer.Apple has 4 months to give me 8.4.1 speed or I will probably sign in for Samsung's iPhone trade in program

Some one once said they could sniff out "micro stutters". By the way, that was not you.

I mean, come on. If we use this threshold for every animation, we'd be on iOS 9.8.4 by the end of the year.

It's gotten to the point that progress isn't even recognized. It's either no lag or nothing at all. That's unrealistic by any measure, since this is evolving.

Hold the home button down before flicking Notification Center to the bottom of the screen. Notification Center has to be pulled down all the way before pulling it up and flicking it back to make this happen.

That for me??

Yeah, you had 3 posts in a row with the lag thread info. (Which I 1000% agree with btw) You could have edited the first post.

Is this real life usage in your opinion?

 

[iOSBry]

For those of you that are interested, I've been submitting bug reports for each instance/type of lag/stuttering/dropped frames in iOS that I encounter with detailed steps to reproduce (where I can) and have six reports where engineering has asked that I enable stackshot logging, reproduce the issue and then send them the logs.

Here's hoping they get to the bottom of these issues!

For those of you submitting performance related bug reports, you might want to enable stackshot logging so you can attach the stackshot logs to your reports - Apple engineer's have requested I do this for six of my performance related bug reports. You can follow the steps here to enable: https://developer.apple.com/bug-reporting/ios/stackshot/

While it may not be normal "real life usage", doing so should never put your device in this state.

Are you saying the bug should stay? Jesus. I talk about performance and people say not to do that here. Then I point out a bug in the "Point out bugs" thread and somehow there's still a problem.

I'm not. I asked if you feel this is real life usage. What does Jesus Alou have to do with that?

Some people just take anything that isn't 100% agreement as a complete and full attack. Makes it rather hard to have a meaningful discussion about much as it's usually just not worth bothering even.

How?

I didn't say "it's just your device" or "smooth here". It's been accepted for a while now that iOS 9 does stutter. However it's the relentless few that feel the need to post their dissatisfaction in any and all threads that even mention iOS 9. Claiming because it's utterly useless to them it's fact that it will be utterly useless to all. When the hard truth is, it varies person to person. So for them to keep "scaring" people away from updating because of their blanket statement, that's when others chime in about only each individual user can decide for themselves if it's good enough (for now and will most likely get better over time) and worth the new features.

The constant whine posts about lag are getting borderline childish at this point when they find their way into every single thread related to or not about it. I swear if someone started a thread "I have 9 safari tabs open" just the fact the number "9" is in the title, lag posts would find their way in there. Again, it's not until then do others chime in to provide whatever OP with more usable feedback instead of whiney one sided BS.

It's also been accepted that iOS 9 does not stutter! There are legions of us that simply do not have that issue! Enough with your blanket statements!

Seems like it was repeated to reiterate the point.

Found a major bug with iPad Air 2. Was also in iOS 9.1.

If you select the far left app (or close to it) in the task switcher you end up with the screen being blurred for a second or two.

I can confirm that this does not happen on 9.0.1 (what my local Apple Store iPhones and iPads are still running) so is definitely software related.

You're the one who won't contribute to any discussion directly related to iOS. I tell you about actual issues and you tell me I'm attacking people and that I have some narrative. You told me you didn't want to talk about performance.

Tell me what you think of this 9.2 bug here on the iOS 9.2 bug thread.

I've been seeing the same issue on two 5S's as well; it's definitely annoying.

It doesn't even have to be the far left, it can be any app that's blurred - tap on the blurred app and it will zoom in blurred for a second or two.

Just updated to PB of 9.2 on my iPhone 6 and it's fantastic. App Switcher is noticeably smoother as is Spotlight being pulled down with Siri Suggestions enabled.

I shall report it via the feedback app and hope it's resolved by the next beta.

All kidding aside, the app switcher is definitely a lot smoother in iOS 9.2 on the iPhone 6.

How about touching apps to open them mid animation while leaving an app? Did they return this behavior yet? Or are you still stuck waiting for the animation to finish completely? I've noticed in 9.1 I can tap app cards in the switcher mid animation and the phone registers it again! Haven't seen that since iOS 7!

 

[RebornProphet]

Instantly noticeable and a very welcome improvement, as is Spotlight being pulled down with Siri Suggestions ... that sharp stutter upon swiping down is gone. Pulling down a text notification to activate Quick Reply was a little stuttery first time I tested it, but after that first test text it was extremely smooth.

Overall the UI is definitely far smoother, so it looks like the reports myself and others have sent regarding lag/stutter have been read and taken notice of.

Now updating my Air 2, although that was already a better experience than my iPhone 6, pre 9.2.

Please report bugs to bugreport.apple.com

Changes:

• App Switcher - scrolling is more sensitive and a new animation is seen when scrolling to the far right of the app previews (beyond home screen preview)
  
• Music - easier to see what music is on the device (Offline music) with new icons
  
• SFSafariViewController - long tapping the Reload button in the SFSafariViewController now gives options to Reload Without Content Blockers and Request Desktop Site, like in Safari
• SFSafariViewController - SFSafariViewController now supports 3rd party Action Extensions. Any Action Extension that works in Safari will also work in SFSafariViewController
• Siri - Arabic added as a supported language.

Bug fixes:

• 3D-Touch - lag on homescreen (iPhone 6S Plus) on light and medium setting fixed
  
• App Switcher - fixed a bug where the icon of the 3rd app on the app switcher would not appear until you scrolled towards it
• Dynamic Wallpaper - screen no longer flashes black when switching to home screen from the app switcher
  
• iCloud Drive - search inside folders and subfolders is fixed
• Settings - settings scroll bug is fixed; however, it occasionally flashes the search settings field briefly before coming into view
• Spotlight Search - pull down overlapping home screen icons is fixed with a workaround, increasing distance between icons and search bar.

Bugs:

• App Switcher - settings screen in app switcher still blank
• App Switcher - scrolling as far to the right as possible and tapping the home screen preview while holding it to the left side of the screen will make the animation jump
• iCloud Keychain - sometimes, while setting up iCloud Keychain, you receive a Could Not Set Up iCloud Keychain error. Workaround: Reboot the device
• Messages - animation missing when tapping on Edit and then Cancel (the messages will just pop back)
  
• Music - "Show complete album" missing when you have less than the full album in My Music
• Videos - videos with 'folw' track associations will fail to play on 32-bit devices.
• If you "reduce transparency": ON, you can´t see the tapping indicator when you write in a white keyboard. No issues with black keyboard. This bug is present since ios 8. (as seen here: Youtube)

Performance improvements/issues:

• Improvements to multi-tasking on iPhone 4s (as seen here: YouTube)
• Improvements to Force Touch lag on iPhone 6s+ (as seen here: YouTube)

Just did update and have the following issues (already reported to Apple)

1. Battery draining rapidly. Went from 48% to 32% in about 15 minute - regular usage on iPhone 6s Plus

2. Does not indicate in top info bar that I'm connected to wifi, even though within the wifi setting screen it shows connected.

***ADVISE NOT TO DOWNLOAD UNTIL THESE 2 ITEMS ARE FIXED. ***

UPDATE: Issue may have been associated with an app I downloaded "Photo Remote". Deleted the app and wifi now shows as connected. Doing a a hard reboot to see if the battery drain stops.

Sorry for pulling the trigger quickly, before looking at all possible causes.

I'll add to my previous report that the app will also sometimes look very distorted and partially cut off until it is rendered properly again.

Assuming these issues are present for everyone and aren't some installation glitch or something like that, which happens often enough.
