Issues on my iPhone 12 Pro after updating to iOS 18.3.1

Since completing the update I cannot control downtime for my children's phones through Family in settings, it just freezes. I have figured out a workaround, but it is very annoying. Apple TV app won't even load, just goes to a white screen and freezes. Settings takes forever come up and trying to do anything takes a long time with lagging. And all the while the battery is getting HOT when it never did that before. I have restarted my phone multiple times and have checked for updates for the apps not working, including Apple TV, I have done all the trouble-shooting things and nothings fixes the issues. When is Apple going to fix the multiple problems this update has caused? I have noticed that I am not the only one having issues, this is VERY FRUSTRATING.

Then you may have to consider wiping and restoring from your backup.

Restore your iPhone, iPad, or iPod touch from a backup - Apple Support

Restore your iPhone, iPad, or iPod to factory settings using a computer - Apple Support

The iOS 18.3.1 update itself is likely not cause of your issues as tens of millions of users have updated without any problems. Unfortunately in life sometimes things go off the rails for no reason. There may have been an existing glitch on your iPhone that caused the update to go south.

If you are not comfortable with restoring your device by yourself you could contact Apple Support or take the phone to an Apple Store or authorized Apple service provider for assistance.

Make sure you have 5g auto turned on under cellelar because then itll go back and forth depending where you are. Not all places have 5g yet.

Sometimes switching to airplane mode helps. Usually doing a network reset helps, but not always. Sometimes rebooting fixes it

I disagree. I experience issues with my email synching after the update - this was on my old phone. I upgraded my phone the next day and still experience the same issues. I’ve removed an email account and reinstalled and the issue is not resolved. It’s the OS upgrade.

Nich. ~ Your iPhone XR could be 6½ years old and the long process of applying an iOS update to an iPhone with a weak, aging battery can be the proverbial "straw that broke the camel's back." So...

Does your iPhone XR still have its original battery?

And what's the Maximum Capacity % here?...

@superqueen The workaround I use is that I go into the settings on my phone and scroll down to Screen Time. Towards the bottom of screen time my kids are listed and I can control their screen time that way, not through the Family in settings.

I fully agree the problem in apple OS related, they need to fix it. They are multiple problems with this Os version.

Yes my iPhone 12 is still running the original battery however the battery status has been showing “Service” for a while now which is basically when it falls below 79% of charge holding capacity

It ruined my phone, too. The moment the update finished, my lock screen stopped working—I can't click any notifications on it anymore. I also am finding that around 50% of both iMessage and SMS have "Failed to send" ever since the update, which has never been an issue before. It also seems to freeze when I open certain native apps, like Photos, or when trying to use them compounded, like taking a screenshot and then trying to send that in a message...it opens the message portion, but when I type in the recipient, the Send just stays gray. I've quit the apps, tried again, but same issue. I forced a hard restart 3 times now, but it hasn't made a difference.

Also, my phone now overheats EVERY time I charge it. This has never happened before the update, all of the problems I am experiencing are absolutely due to the software update, as every single one of them started happening immediately after the update and never before.

Then please explain why the vast majority of users, myself included, are not seeing these issues with the update. Can you do that? Believe what you will but you’l be waiting a very long time for Apple to fix something that almost no one else has experienced. There are now 2 billion iPhone users out there.

18.3.1 broke the YouTube iOS apps for me. I can no longer post any comments on any videos and in some cases I can’t even read comments. Everything works fine if I sign into YouTube via Safari web browser. I tried everything. Deleting history, deleting and reinstalling the app, etc. its a huge hassle using safari for YouTube in iOS.

I too am having issues. Primary being that using headphones while on a call works for a little while, then just stops! I can’t hear the person I am on a call with, but if I switch to using speaker, can hear the person talking.

During the call or while listening to a movie/TV show, it will make a weird pixilating noise (best way for me to describe)…sounds like an electronic randomization noise…then if on a call, the person is asking if I am still there.

This is extremely frustrating! It is happing with two different brands of headphones. Neither are Apple, which should not make a difference; the issue did not start until the latest update.

@aubreyg - I am having the same issue with Family downtime - cannot even access the Screen Time submenu. Please let me know what your workaround was? This update has created a host of problems on my phone and I am infinitely regretting having automtic updates selected!
