IOS9 upgrade mobile data toggle not working

I encountered this data cellular problem. Everytime i turn to on the a specific app, it goes back to off. Can somebody help to figure out how to resolve this? Or is this really the result of updating the ios to 9? Please Help me!! This make me sick! 😟

This really is a result of iOS 9 upgrade I am afraid... I have spoken with Apple Support and they are aware of it and say that it will be resolved in the next iOS release.... Sadly no date have been provided as to when that will be.

Same issue here! Iphone 6 64gb user here. i hope apple gets to fix this asap. This is a very important feature. please please please

my problem with this is strictly with Spotify. I can toggle data for all other apps. Tried resting phone, deleting and reinstalling the app. nothing works. gotta love upgrades! 😮😢

Just chatted with tech support. He says that the problem is now well reported, that it's a known issue they are working on and that there should be a fix soon. No timetable given. Also, as noted in this thread, advised that a restore can help alleviate the problem if you can manage losing the data accumulated since last backup.

I'll be waiting for the fix. The apps I had on cellular data are the most crucial and can't afford to lose data.

Same for me. I have 4S. Anything I had toggled off will not stay on and anything I had toggled on will not stay off.

Same problem here. The iOS upgrades are starting to get eerily reminiscent of the Microsoft upgrades, and endless "patch Tuesday's."

I have this exact problem with a few apps, not all apps on my iPhone 6 with iOS 9. It's weird and I don't see why it would just automatically toggle back when I leave Settings. I am trying to figure out the possible scenarios that would have caused them to toggle back to original states but I couldn't. I tried restarting and it didn't work. I tried several ways to turn cell on for Facebook and it kept turning off every time i exit Settings.

Definitely poor programming on that one. It should never revert back to original state if it showed a toggle feedback. It's like flipping a light switch and it turns off itself when you get in the room.

Same issue here!

pla fix it, Apple! Pffff

tthe same thing happened to me. I would turn off cellular data for apps of and on all the time but the ones that were switched off when I updated won't turn on now. It ***** and I see a lot of iPhone users having this problem after the new update. I definitely wont be resetting my phone. Apple needs to fix it ASAP

thats true. The most annoying thing is, iTunes cannot do separately backup. It means we also backup the bug to the backup Package.

i tried twice followed by Apple service instruction. still the same. They never admitted its a bug, just keep telling me your third party apps caused a system crash. cunning excuse

Hi everyone, I had the problem and you can fix it by downgrading to ios8 (do a local backup first!), I followed the instructions here: http://www.phonearena.com/news/How-to-downgrade-your-iPhone-or-iPad-from-iOS-9-t o-iOS-8.4.1_id73875 (please note: step 4 may be wrong, I entered DFU with the instructions in https://www.theiphonewiki.com/wiki/DFU_Mode but the rest is ok). I hope it helps! None of the other tips worked, and I guess we'll have to wait until Apple releases a real fix to ios9 to update!

I wouldn't do this personally. If it's not an official Apple process it could invalidate the warranty.

I have this problem on my iPhone 6 model MG4F2LL/A with iOS 9.

don't worry, you are not alone
