My iPad air is working much better than iOS 8, but the iPhone 6 features some slightly lag not present on iOS 8 so I'm gonna try it for a few more days to decide.
 
The way I've done this in the past is to put he phone in recovery mode and then have iTunes take care of it all (it would download the latest public version--8.4 in this case--and install it, and then you can restore the last 8.4 backup basically).
 
Control-Click the backup, and instead of selecting the "Archive" option like it shows in the second image on the linked Apple Support page, click "Show in Finder." Open the folder it pulls up, then open Info.plist. Scroll down in that plist and find the "Product Version" key... that should show you what version of iOS you were on when you created that backup.

excellent thanks!!
 
I downgraded my 5S because WhatsApp and LINE got some cosmetic issues on iOS 9 PB1, and the interactive pop gesture (i.e. swipe-back) across the entire system has glitchy transition. You can try to slow your gesture to see if this happens on your device. :/

Same for my Air 2, since the apps in my use patterns have no Split View or Slide Over support so far. So no point to stay...

I'll miss the Mail.app though. The actions of notifications finally replicate the swipe actions but not just one of them.

Go here http://www.felixbruns.de/iPod/firmware/
In the drop down menu download the .ipsw for your device (it downloads it directly from Apple, nothing shady here)
Open iTunes and plug in your device
Go to the main device summary screen
Windows: Shift+Click on Restore
Mac: Alt/Option+Click on Restore
Then browse for and double click the 8.4 file. Make sure it doesn't do a backup so your 8.4 backup isn't overwritten
worked like a charm well done mate!

Yup. I'm going back on my two iPads and my 6 Plus. Amazon Prime Movies wouldn't work on my Air 2 and some strange network issues on my iPhone and iPad Mini.
 
To be honest, iOS8 has felt like a beta throughout its entire existence. So I'm perfectly fine with running an iOS9 beta because, unlike iOS8, at least I know that Apple is putting effort into addressing reported issues. :D
The problem is that iOS 9 may break existing apps that are not optimised to run on them. And the developers won't be able to issue a fix for them until many months later.

Is that true? I thought they weren't allowed to make use of ios9 features or issue bug fixes solely for ios9, but could incorporate fixes in their planned releases for ios8?

I'm not a Dev, so don't know what is allowed by the agreement, hence asking.
 
Back to 8.4.... I was curious about 9 but now I want my phone working again. Still too buggy, but I sure miss some nice IOS9 features already.
 
Nope. I'm very satisfied with iOS 9 at the moment. A few bugs are present, but nowhere near enough to make me downgrade. I'd like to see what later betas will yield to us.

This. Bugs have been rare for me, and battery life is actually pretty good! What bugs I have encountered, I sent back through Feedback Assistant.
 
I am not going to be downgrading, things are fine so far. Yes, battery life is iffy, but it still gets me through the day. Plus, the last couple days have been busy, involving a lot of LTE + high brightness use, so yeah. The other real issues really are just low frame rates and sluggishness. There are a fair share of general bugs but nothing has been too problematic for me.

I don't have a backup archived, and I feel dumb for that. I looked into it, but all I could find was stuff for Mac, and I have a Windows PC. I plugged in my iPad to restore a backup onto iOS 9 to get my stuff back but it automatically started backing up on its own, and it overwrote the last one. I never had iTunes just automatically back up without me initiating it first, so... Oops. I think I'm fine with iCloud backups though, those go nightly I believe, and even if I lost everything, it's all in iCloud anyway. I am not a huge app user either, and I don't have any super important app data either.
 
I am downgrading my 5S because the network goes unresponsive after some time and I stop receiving any calls. Beta 2 was good, beta 3 is terrible. I also get some ghost Nike kind of green tick for milliseconds once I tap the phone icon.

8.4 is really good. But I will miss the 60fps smoothness of Weather app from iOS 9.
 
I tried but failed. I guess my back up was't current enough. Luckily, I did the upgrade on an iPad Air that usually collects dust.
So, since mail wasn't working at all for me, I decided to restore. When I did the encrypted restore in iTunes, My iPad Air came back with iOS 9 with most of my data and settings gone, but mail was working and the glitches in notes were better. So, although I am stuck with 9, the iPad is useable so I don't mind.
I will proceed with bata testing, but my report button is gone.
 
I went back to 8.4 the other day and it broke my iCloud notes, they would no longer sync together with my iPhone and iCloud.com so I've gone back to iOS 9 and it works perfectly again.

Just a heads up.

If you want the button back just install the profile again. You will want it for the next update too.

If they can fix bugs seen on iOS 9 using the current released version of Xcode then they can do so. Only some developers will do this, as its a moving target - they could make a change to fix a bug in a beta only for Apple to change how it works in a subsequent betas.

(Hat tip to Edovia, who are fixing an issue in Screens so it works in 9.0 beta!)

Just so you're aware, apps won't support slide over or split view till September. Apple won't allow iOS 9 app updates until the GM is released.

Correct. Devs are not allowed to submit apps for approval that are made with the iOS 9 SDK and therefore must attempt to fix bugs with the iOS 8 SDK. Apple won't allow iOS 9 SDK apps until September when the GM is released.
