15 annoying problems with iOS 8 (and iPhone 6) and how to fix them

 

Bug: Wi-Fi slow and dropping signalApple iPhone 6 Plus review

A lot of people have experienced a Wi-Fi problem after updating devices to iOS 8. The Wi-Fi signal will appear to be strong, but websites are slow to load and video slow to buffer. In some cases the connection seems to drop altogether, and in other cases it just slows to a crawl. You may get a message that “the server has stopped responding” if you’re trying to use Safari. Other devices are still able to connect to the router and enjoy the usual speeds.

Workarounds:

  • Toggle Wi-Fi/Airplane mode: You might find that it comes back temporarily if you toggle Wi-Fi off and then on again. Alternatively you could switch on Airplane mode and then turn it off again. Swipe up from the bottom to open the Control Center and toggle these settings.
  • Reboot: Some people report temporary success by switching the device off on and again. Press and hold the Sleep/Wake button and the Home button for ten seconds or so, until you see the Apple logo. Your Wi-Fi may work again for a while.
  • Turn Bluetooth off: Sometimes Bluetooth can interfere with Wi-Fi speeds so you could try turning Bluetooth off. It won’t fix the issue, but it might reduce it.

Potential solutions:

  • Reset Network Settings: Try going to Settings > General > Reset and tap Reset Network Settings. This has worked for a few people, but the problem might return.
  • Turn off Wi-Fi Networking: Try going to Settings > Privacy > Location Services and under System Services you need to toggle off Wi-Fi Networking.
  • Toggle 2.4/5GHz: If you have a two channel router then try changing from 5GHz to 2.4GHz. Generally speaking 5GHz is faster, but with a shorter range. Some people report a better connection on 2.4GHz and a few find an improvement by switching the other way.
  • Change router channel: You could also try changing the channel on your router. You’ll need to put your router’s IP into your browser and log in to change settings. Refer to your ISP for instructions.
  • Switch DNS to Google: Some people report success after switching DNS to use Google servers. You can do this via Settings > Wi-Fi then tap the ”i” icon next to your router, scroll down to DNS and tap the numbers, then enter “8.8.8.8”. You might have to restart your device for this to take effect.
  • Factory Reset: It’s a drastic step with no guarantee of success, but you could try a factory reset. Here’s how to factory reset an iPhone.
  • Update probably coming: There’s clearly some kind of glitch in here, so Apple is very likely to release a patch to deal with it. Keep an eye on Settings > General >Software Update.

 

Problem: Rapid battery drainApple iPhone 6 Plus review

A lot of people seem to suffering with a fast draining battery after the iOS 8 update. Some are reporting extreme cases where their iPhone is going from 100 percent to dead within four hours.

Workarounds:

  • Check out our iPhone battery tips for some suggestions.
  • Try holding down the Sleep/Wake and Home buttons until the device restarts.

Potential solution:

  • There’s a good chance that a specific app is causing the problem. Go to Settings > General > Usage > Battery Usage and take a look at what is guzzling down that battery juice. If you find a specific app that’s draining a suspiciously high amount of battery then check to see if there’s an update available and if not, think about uninstalling it. If you need it then try disabling Background App Refresh via Settings > General and Location Services via Settings > Privacy.

Issue: Sound not working

This seems to be a common issue for iPad owners after the iOS 8 update, but thankfully there is an easy fix that seems to be working for most people.

Potential solutions:

  • Hold down the Sleep/Wake button and the Home button together for 10 seconds or so until the device restarts and you see the Apple logo.
  • Check in Settings > General under Use Side Switch To and make sure Mute isn’t ticked or toggle the side switch. You can also check by swiping up and taking a look at the icon on the right in Control Center.

Glitch: Syncing music takes a long time or won’t workApple iPhone 6 Plus review

A few people have run into an issue after the iOS 8 update where they’ve installed iOS 8 and had to restore the device, and the process takes a very long time to sync (24 hours or more), or appears to hang indefinitely.

Workaround:

  • If you have a large number of tracks with artwork then it could be the culprit. Try deleting the artwork from your library and sync again.

Potential solutions:

  • Load up iTunes and find your iPhone, iPad, or iPod Touch in the left column. Choose it then look under Summary at the Options section to find Manually manage music and videos. If it’s already check then try unchecking and re-checking it. You may need multiple syncs to get it to work. You may also have to toggle iTunes Match off under Settings > Music on your iPhone.
  • You can also try connecting the device to your computer and firing up iTunes. On the device go to Settings > General > Usage > Manage and delete all the music. In iTunes go to the Music tab and uncheck Sync Music then apply. Now check the Sync Music box again and it should sync up correctly.

Problem: iMessage won’t send and group conversation problems

There are a couple of different problems cropping up with iMessage after the iOS 8 update. Some people can’t send iMessages at all; others are having an issue with group conversations where it will only send them as SMS.

Workaround:

  • If you’re having the group message problem then you can alleviate it by deleting the old group conversation. When you start a new one with all the same people you’ll find you can send iMessages again and it won’t default to SMS anymore.

Potential solutions:

  • If you find you can’t send messages at all, maybe you’re stuck with a “Waiting for activation” message, then try going to Settings > Messages and toggle Send as SMS and iMessage off. Now go to Settings > General > Reset and tap Reset Network Settings. If you go back to Settings > Messages now you should be able to toggle Send as SMS and iMessage back on and it should work.

Glitch: Random reboots and BSOD

A few people have been experiencing random reboots, crashes, and the dreaded blue screen of death after updating to iOS 8. They seem to occur fairly frequently and apparently randomly while users are doing all sorts of different things. This seems to be more common with iPads.

Potential solutions:

  • Try going to Settings > General > Reset and tap Reset All Settings. It won’t delete any of your files or apps, but you’ll need to re-enter passwords and choose wallpaper again.
  • It’s possible that an app is causing the problem. You can try uninstalling apps one by one and testing or you can try a factory reset and selectively reinstall.

Bug: Can’t upload photos in Safari browseriPhone 6 screenshot 7

A lot of people have upgraded to iOS 8 only to find that they can no longer upload photos to any website through the Safari browser.

Workarounds:

  • If you’re trying to upload to a website like eBay then download the dedicated app and use that instead of Safari.
  • You could also use another browser like Puffin or Chrome.

Solution:

  • This is clearly a bug in the mobile Safari app and it should be fixed with an update that will hopefully come very shortly. We’ll keep you posted.

Problem: Spotlight Suggestions and Bing Web Results

A few people have been disappointed at the fact Spotlight Suggestions isn’t working for them. They are going in to Settings > General > Spotlight Search and trying to activate Spotlight Suggestions, but it won’t stay on. Some people are also experiencing a crash when they try to enable Bing Web Results in Settings > General > Spotlight Search.

Explanation:

  • The Spotlight Suggestions feature is only available in a limited number of countries. There’s a list at Apple’s website.

Workaround:

  • Some people have managed to get it working by going to Settings > General > Language & Region and switching to a supported country. You should try to make sure your language and region settings match and try restarting the device after changing the settings.

 

Issue: Sluggish performance

A lot of people have been complaining that the iOS 8 update has resulted in laggy and sluggish performance on their iPhone or iPad. This is more common, the older the device is. They actually ran a comparison test at Ars Technica — with an iPhone 4S running iOS 7.1.2 and one running iOS 8 — and found the update has significantly slowed boot time and app loading.

Workaround:

  • Don’t update! If you have an older device and you haven’t yet updated, then don’t.
  • How to downgrade: If you have already updated then there’s a short window during which you can downgrade from iOS 8 to iOS 7.1.2 again. Apple will stop signing iOS 7 soon, so this will stop working at some point. You’ll need a copy of the iOS 7.1.2 firmware in the form of an IPSW file. You may have it on your computer from the last time you updated, so search first. If not, you can find them at Redmond Pie. Turn off Find My iPhone in Settings > iCloud. Plug your device in and fire up iTunes then choose your device and look at the Summary tab. Now hold down Shift and left click on Restore (or the Option key and Restore on Mac) and choose the iOS 7.1.2 IPSW file. Bear in mind that you can only get all your apps and settings back if you have a valid backup to restore from that you made while still using iOS 7.

Potential solution:

  • You can wait for further updates. There’s a chance Apple will make improvements in the first few updates for iOS 8, it did do this with iOS 7, but there’s no guarantee.

Glitch: Personal Hotspot has disappearediPhone 6 screenshot 9

After updating to iOS 8 a few people have been surprised to find that the Personal Hotspot option has just completely disappeared from the Settings menu. Luckily there’s an easy fix that seems to be working for the majority.

Potential solution:

  1. Go to Settings > Cellular > Cellular Data and type something in the user name field then go back and the Personal Hotspot option should appear in Settings.
  2. If that doesn’t work then go to Settings > Mobile Data > APN Settings and take a look, then make sure your carrier settings are the same under Personal Hotspot.

Problem: Device won’t charge or slow charging

A number of people have encountered issues with charging their iPad or iPhone after updating to iOS 8. In the majority of cases the device simply won’t charge at all when plugged in. In some cases it is charging very slowly.

Potential solutions:

  • Apple wants you to use official chargers and cables and it may block third-party chargers or cables from working. Try using the original cable and charger that came with your device. Some people are reporting that this problem is occurring even when they use the original charger and cable, but it’s worth trying first.
  • Hold down the Home button and the Sleep/Wake button until your device restarts and you see the Apple logo.
  • Try a different outlet, a different cable, and a different charger. If you’re trying to charge an iPad then make sure you aren’t using an iPhone charger.
  • Try plugging your device into your computer via USB and see if it charges. You might consider doing a restore through iTunes.
  • If you have a fake Apple charger, a third-party charger, or even an old charger you might have to spring for a new, official Apple charger.

 

Bug: Camera app upside downApple iPhone 6 macro camera

After updating to iOS 8 some iPhone owners launched the camera app to find that the top bar was displayed upside down. For some people it even began to start taking photos upside down and the issue extended to third-party apps like Instagram. Luckily, the fix is easy.

Solution:

  1. Open the Compass app and calibrate it.
  2. Now hold down the Sleep/Wake and the Home buttons until the device restarts and you see the Apple logo.
  3. This seems to have solved the issue for most people and it should work if you find FaceTime or anything else is upside down as well.

 

Glitch: Screen brightness too dim

Some iOS 8 device owners have complained about a screen brightness glitch. The problem is that the screen on the iPhone or iPad will suddenly dim while they’re using it despite the fact that auto-brightness is turned off.

Potential solutions:

  • Try going to Settings > Display & Brightness and toggle Auto-Brightness Now turn it off again, andhold down the Sleep/Wake button and the Home button to restart the iPhone (it should shut down and then you’ll see the Apple logo when it restarts).
  • Go to Settings > Accessibility > Increase Contrast and toggle Reduce White Point to off.
  • If you’re having an issue with the auto-brightness, then go to Settings > Display & Brightness and just turn the brightness up, it should set a new base level.
  • Some people found it improved after turning Zoom off in Settings > Accessibility.

 

Bug: Notification banners get stuck

A lot of people have found that sometimes the notification banners that pop up at the top of the screen to warn about incoming messages get stuck there. Flicking doesn’t seem to get rid of them. This bug occurs frequently when watching video in landscape mode, but it’s not confined to that instance.

Workarounds:

  • You can press the Home button once and the banner should roll up.
  • You can rotate your phone from landscape to portrait and back again.
  • You can turn the screen off and on again.

Potential solution:

  • This should be fixed in the next update when it rolls out.

 

Problem: Can’t make calls

There have been a few reports of iPhone owners with various different models of older iPhones, including the iPhone 4S and iPhone 5, being unable to make calls after the latest iOS 8.0.2 update. When attempting to make a call the connection continually drops or isn’t established in the first place. Some people are also unable to send text messages, but report still being able to receive incoming calls or texts.

Potential solutions:

  • Double tap the Home button and swipe all the open apps up to close them.
  • Try holding down the Sleep/Wake and Home button together until your iPhone restarts and you see the Apple logo.
  • Make sure that you don’t have Airplane mode on and check that you’re not trying to call a blocked number in Settings > Phone > Blocked.
  • Try turning the iPhone off, removing the SIM card, and then replacing it.
  • Go to Settings > General > Reset > Reset Network Settings.
  • Go into Settings > Cellular and or Settings > Mobile and change your Voice & Data
  • Contact your carrier and make sure there’s no problem with your area or service contract.
  • If you’re still having an issue, try backing up and restoring your iPhone as new.
