Here is the last part of common issuses,
1. Cannot delete apps in iOS 10
If you can't delete apps from your iPhone or iPad after upgrading to iOS 10 then you're not alone.
Users are reporting that when trying to delete an app they just see a message saying "Waiting", and the usual X icon to delete the app doesn't appear.
To fix this problem first perform a hard reset of your iOS 10 device.
Do this by pressing and holding the power button and the Home button at the same time for ten seconds until the Apple logo appears.
If that doesn't help, check to make sure you're not installing any apps in the background while you try to delete other apps.
To do this open the App Store then tap on Updates > Purchased.
See if any of the apps have "Installing" next to them. If they are, put your device into Airplane mode,
then tap on the apps to stop them. Next, turn off Airplane mode and download the apps one by one.
You may also need to try resetting all your settings. Open up the Settings app and select 'General'. Scroll down and select 'Reset' then 'Reset All Settings'.
2. Third party keyboard don't work in iOS 10
Many iOS 10 users are noticing that when using a third party keyboard,
such as Swype or Bitmoji, the keyboard becomes unresponsive and crashes.
Most of the developers behind these keyboards know this is an issue and have released updates that have fixed compatibility with iOS 10,
so the first thing you should do is check the App Store to see if there is an update waiting for your keyboard.
If there isn't you will have to disable the keyboard by going to
Settings > General > Keyboards and tap on 'Edit'. Next, tap on the minus button, or swipe left, on the keyboard you want to remove.
3. Purchased ringtones have vanished in iOS 10
If you've bought and downloaded custom ringtones, you may not be able to find them if you've updated to iOS 10.
This is a problem that has happened in previous updates,
and thankfully there's an easy way to get them back without having to purchase the ringtones all over again.
Simply plug your iPhone or iPad into your PC or Mac and launch iTunes.
Click on your device in the top menu, and under where it says 'On My Device' click 'Tones'.
Now make sure the check box next to 'Sync Tones' is selected. and you'll be asked if you agree to removing and replacing your ringtones.
Agree, and the sync process will start.
If that doesn't work, check out our guide on How to restore ringtones to iPhone for more methods.
4. Alarms are not working in iOS 10
There's nothing worse than an important alarm not going off, and sadly that's what some iOS 10 users are currently experiencing.
If you've found that your alarms are either not going off at all, or they go off at the wrong time, then there's a straightforward solution.
Open up the Clock app and go to 'Alarms', where you usually set your alarms.
Click the edit button at the top of the app, then delete all of your alarms. Close the app, then reopen it and add your alarms back in.
If that doesn't work you'll need to be a bit more ruthless. Go to Settings > General > Reset and tap on Reset All Settings.
This will reset all your settings to default. It means everything you've configured will be set back to the way it was before you tinkered,
which is annoying, but at least it means you can now reset your alarms and they will work again.
5. iPhone screen no longer works
If your device's screen no longer responds to touch inputs after updating to iOS 10,
then unplug your iPhone or iPad and remove any case or screen protector.
Clean your screen, then restart your device. If your device's screen still does not work, you can try adjust you 3D Touch settings.
To do this, go to Settings > General > Accessibility > 3D Touch.
You can then adjust the sensitivity. If it still doesn't work, you may need to contact Apple Support.
26. Device gets hot when charging after iOS 10 update
If you've noticed that your iPhone or iPad has started to heat up when charging after being updating to iOS 10, don't panic.
Even though it doesn't look like it, iOS 10 may still be updating apps in the background immediately after the update,
so when it's being charged it may run hotter than usual.
Give it time, and hopefully your iPhone or iPad will return to normal temperatures when charging.
7. Photo albums no longer sync in iOS 10
Some iPhone owners are reporting that when trying to sync photo albums from their Macs to their iPhones running iOS 10,
the photos sync to the device, but their respective albums aren't showing.
So, while the photos are on the iPhone, they can be difficult to find,
as they're no longer sorted in the albums they usually appear in.
One user on the Apple Support forum found that by opening a folder on their Mac called 'iPhone' they found lots of subfolders containing photos.
Usually this folder and its subfolders get synced. To fix the problem,
they added two new subfolders into the iPhone folder and tried to sync – and it worked, with all the albums then appearing as they should in iOS 10.
8. Playlists appear empty after updating to iOS 10
A common problem with iOS 10 involves songs in playlists created in iTunes not appearing on the iPhone.
This problem mainly involved Smart Playlists, and although they appear on phones, they now look empty.
To fix this problem plug in your iPhone and open iTunes. Select your device and uncheck all playlists to stop them syncing.
Apply the changes, then check the boxes to sync the playlists and they should now appear on your iPhone after the sync process has finished.
9. Games run slow in iOS 10
If you find that graphically intensive games are now slow to open, and feel sluggish when played,
then close down all of your open apps, then press and hold the power and home buttons for 10 seconds until the Apple logo appears.
This resets the device, which should sort out any problems. It's also worth making sure that you have the latest version of the game installed,
as app makers may have released an update to make their apps and games work better with iOS 10.
10. Emails don't appear in iOS 10 Mail app
If you're using iOS 10 and you open up the Mail app, you may be greeted with a blank screen.
A number of iOS 10 users are reporting this problem, and they all seem to have one thing in common: having an apostrophe in their email address.
It appears that a bug in iOS 10 is preventing the Mail app from showing these addresses.
So, if you do have an email address with an apostrophe in it, you'll have to wait for a fix from Apple.
In the meantime, if you have other email accounts you can make emails to those addresses appear by removing the mail account with the apostrophe from the Mail app.
The other email addresses will now appear.
Many email accounts let you forward mail to another email address, so until a fix is released you could set emails that go to your email address with an apostrophe to be forwarded to another address.
The process for this varies depending on the email provider, so visit the website of the company that supplies your email address for more information.
