iPhone 6 keeps freezing after update 9.3.1

Do you see a flickering line at the top?

This exact same thing has been happening to me! It is incredibly frustrating. I've been unable to identify a pattern. I know for certain it happens in Messages, in Safari, when trying to switch between apps, when trying to use the keyboard. There is no warning, no flicker, just suddenly everything is frozen. Sometimes it eventually comes back to life, usually I have to reboot the phone to fix it. I have noticed a general choppiness that seems to accompany animations (the zooming in on a text field, like this one, when entering text, but it seems unconnected to the freezes; perhaps it's not.)

It's getting to the point that it's starting to feel like my old Blackberry when I had to pull the battery multiple times during the day. I'm having to reboot my iPhone 6 at least twice a day. 😟

have you tried a hard reset?

hold both the home button and power button in until the phone restarts itself.

Just a quick suggestion to try!

Unfortunately I do hard resets whenever it happens and although it fixes the current freeze it doesn't stop it from happenimg again in the near future.

I do think it may only be temporary freezing, however when I need the information on my phone asap I don't have time to wait, it is faster simply to perform a hard reset of the phone.

I mentioned before it appears to happen most when trying to switch between apps and entering text but scrolling may also play a part as this frequently happens when performing that motion; however it may simply the case that I notice the phone is frozen the most when I'm trying to scroll and there's no response, I honestly don't know yet what is actually causal.

I have exactly the same problem and also having to do a soft reset each day - sometimes 2 or 3 times. Have all latest software and loads of memory spare so troubleshooting guide not much help. Doing a soft reset (power and home buttons together) is time consuming. Yes it solves the short term problem but for the cost of this phone this isn't good enough. As with you all, I don't have time to muck about and the freezing has lost me a number of incoming calls.

BTW - what you're referring to as a hard reset is in fact a soft reset. A hard is where you do a factory reset - which I'm really reluctant to do given that not all of my apps on my iphone 5 reappeared on my iphone 6 (yes I did a back up before)

It would be nice if Apple bothered to join in this and tell us what they're doing about it rather than us all agree we've got the same problem!!!

Exactly, I'm also looking for some help with this issue, Apple could offer some level of input given the huge number of users experiencing the same problem. The hard reset is a very temporary fix.
