Apple has just released the new iOS 10.2.1 update for iPhone, iPad, and iPod. According to the release notes, the new patch is all about fixing existing bugs (that likely existed in the previous update), and improving the overall security in the system.

However, besides the new features and security patches, the new update brings something that users won’t be happy about. Namely, we’ve bumped into a few reports on Apple’s forums, about some issues that bother users who installed iOS 10.2.1.

So, we’ll let you know about these problems in this article, so you can know what to expect from the update, in case you haven’t installed it yet.

iOS 10.2.1 reported issues

Let’s start from the beginning. One user complained on the forums that he’s unable to finish downloading the update. According to him, the downloading process stops at 11 minutes remaining, without any further progress:

“Got my iphone6 from my brother,  its IOS is still 8.1, i’m having a hard time updating the ios since the update avilable  is 10.2.1.. i know it will take longer time to update but its almost 2days and still unable to successfully install it, any suggestions on how the update will push through? It’s been like that for 24hours though the time remaining is 11minutes.. “

Another user from the forum suggested that updating the system via iOS will solve the problem. We haven’t tested this method yet, but if you’re experiencing update problems, you can give it a try. Or you can try with some of our solutions for iOS 10.2 updating problems.

It looks like people who managed to install the update have their fair share of problems, as well. Another user  reported that he’s unable to booth his iPhone 7 after installing iOS 10.2.1:

“The actual update 10.2.1 killed my iPhone 7. The device will not boot direct after update. Has anyone the same problem? Is this a known behaviour / bug?”

However, this problem can be solved by pressing the Sleep/Wake and Home buttons, that resets the phone. Additionally, you can look for more solutions on Apple’s support pages.

Another user reported  on the forums that he’s unable to send any emails from his iPhone 6 and iPad Air 2 after installing the update:

“I updated my iPhone 6 and iPad Air 2 to iOS 10.2.1 yesterday night. While I can receive email on my various pop3 accounts ( & godaddy hosted accounts), I cannot send anything. I keep getting error messages to have me check my SMTP settings ( serve) — which are unchanged from before last night, when it was working fine. Please help!”

One user suggested that re-adding the account in Settings resolves the problem. However, the forum thread has no other replies, so we can’t confirm if this is true.

In addition to these ‘fresh’ problems, users also report that some of the previously present problems still occur, even after installing the new update. The list of problems includes: WiFi connectivity issues, Bluetooth connection problems, strange battery drains, and more. So, it appears that the new update didn’t solve all the problems for all users.

Maybe apple should do the similar thing as Microsoft when announcing new Preview builds for Windows 10, and start adding “Known issues” to updates’ release notes. In order to give people a better insight into what a new update might break.

In case you’ve experienced some other problem that we didn’t list in this article, feel free to let us know in the comments below.


  1. When i try to update my iPhone 6S to iOS 10.2.1 it wont even verify the update as it says I’m no longer connected to the internet but there is nothing wrong with my internet connection. I have tried over 20 times & its so frustrating.

  2. I’ve tried to update my iPad Air 32 GB Wifi cellular from iOs 10.2 to iOS 10.2.1 , But sadly it wouldn’t work so now my iPad comes up with a screen saying :
    connect to iTunes via USB.
    Trying that iTunes recognises my iPad telling me that I have to update to iOs 10.2.1 so I tried that, but when the software has completed rolling out. Then suddently iTunes can’t see the serialnumber , now saying i/t instead of serialnumber. Still it says that it is installing software followed by the message that it is installing firmware – then after a little while progressbar on iPad stops at approx. 60 % – and iTunes brings a screen saying that iPad can’t be updated giving an error-code 50 – same result after several attempts.
    As a last attempt I tried to restore to factory-settings. In the first place I didn’t dare that since I hadn’t made a backup.
    But I came up with the same result.
    Now Apple-support suggests that I should get a service for my iPad.
    Does anybody have another idea of what I should try before bringing it to service?

    Bad luck for me since the guarantee-period has been running out.
