iPhone 7 starts lagging

Dear all


My iPhone starts to lag.

(freezing display for approx. 10 seconds, unable to make phone calls (for approx. 10 seconds))


Restarting the device helps for some time.


Is there a way to analyse the device?

(tools, diagnose etc.)


I have 256 gb space.

I use 200 gb.

(so I suppose this is not the problem.)


Happy for any advice.


Kind regards

iPhone 7, iOS 12

Hello bedu,



Thanks for that info and for choosing the Apple Support Communities. If I understand correctly, you are having an issue with your iPhone being unexpectedly unresponsive. First, make sure your iPhone is up to date, as the updates contain stability fixes that can resolve issues like yours, as well as important security updates to keep your iPhone safe.



Update the iOS software on your iPhone, iPad, or iPod touch



If you're still having this issue, your next step is to reinstall iOS on your device; this will help us isolate the situation further. Reinstalling iOS should not affect any of your data, but it is always a best practice to make sure you have a current backup in either iTunes or iCloud.



How to back up your iPhone, iPad, and iPod touch

Transfer photos and videos from your iPhone, iPad, or iPod touch


Once you have a current backup, follow the steps from the "If your device turns on but gets stuck during start up" section in this article:


If your iPhone, iPad, or iPod touch won't turn on or is frozen


Use the “Update” option and not “Restore” and these steps will reinstall iOS. Keep in mind that these steps were written for a different issue, but they will still help us isolate the situation further.



Cheers!

Hey Starr C.


I did an update with the update option.

(I thought this would keep me on 12.14 but it automatically took 12.2)

So, basically I made an usual update, I think.


So, I'm on 12.2 and everything runs fine.

(didn't have any freezing since.)


Thanks for your advice and your helpful instruction.


Cheers!
