hi everyone Aaron here for zollotech and today apple released ios 15.3.1 to the public this is
available now at the same time everywhere around the world and is available on iphone 6s 6s plus
all the way up to the latest iphone 13 and 13 pro max now if you're not seeing the update just go to
your settings go to general then go to software update and you should see the update there
if you're still not seeing it turn off automatic updates and then check again and you should see it
however if you're a beta tester and you're on ios 15.4 you won't see the update right now
now this particular update came in at a fairly small 254.9 megabytes that's on my iphone 13 pro
and it was about 200 megabytes on all the other devices you'll see in this video now along with
this update apple also released ipad os 15.3.1 watch os 8.4.2 which is a bit of a surprise since
we had 8.4.1 last week as well as mac os 12.2.1 all of those are available to the public right now
now let's go ahead and take a look at the build number and talk about what's new so we'll go
to settings then we'll go to general then about under software version if you tap on the software
version there you'll see the build number and the build number just lets us know that we're on the
current version you can see the build number is 19d52 and anytime we have a 15.3 and then 0.1
it typically means we have a bug fix and security update there was something critical that apple
needed to resolve and the first thing is there is no modem update on 15.3.1 at least on the
13 pro so if you were having issues switching between 5g 5g uc 4g lte or anything like that
this shouldn't be really any different than the previous update of 15.3 since they haven't updated
the modem however they have resolved a few issues now the first thing that they've actually resolved
and they've mentioned has to do with accessibility if we go to settings then we go to accessibility
if you're visually impaired you can use a third-party braille display and people were
having issues with this where it wouldn't respond sometimes so if you were using a braille display
with your device whether you're visually impaired or you needed it to learn braille
it should now work properly so that's great to see they've fixed that bug and if you were having
that hopefully it's resolved it for you earlier today apple also released a press release about
air tags and unwanted tracking there's been quite a bit of concern around this if you have air tags
and maybe they're not just tracking things like backpacks and more so you'll see as we scroll
down they've been working with law enforcement and it says advancements coming to air tag and
the find my network new privacy warnings during air tag setup addressing alert issues for airpods
and updated support documentation so they've been addressing issues around this and there
will be changes in the future so that we can have more information if there's an air tag around us
that doesn't belong to us so we'll see those updates in the near future as far as other
issues they've resolved well the one thing they haven't mentioned is the pink screen issue
they've acknowledged that publicly but the pink screen what that means is the display would turn
pink or purple and then fully reboot they haven't mentioned whether they've fixed that or not and
they didn't fix it in ios 15.4 betas yet so we're waiting to see if they've actually resolved it
however with the storage bug it does appear that it's much better now now they haven't mentioned
it publicly but if we go to general then iphone storage on all the devices i've tested it here
with the 12 pro and or the 12 pro max and the iphone sc second generation it seems to load
much much faster and be accurate so if i go to iphone storage you see it just popped up there
and it took within five seconds or less and fully populated with all of the different storage
including system data which sometimes doesn't show up so hopefully that's resolved for most people
most people said it was working for them in 15.3 but there were some issues where it wasn't
now it seems to be fully working in this update so it looks like they've resolved it
hopefully it's resolved for you but they haven't mentioned it publicly the other thing they haven't
mentioned is the music bug there's a music bug that they had with 15.3 and earlier versions
where if you're streaming music maybe you're streaming instead of downloading it to your device
it can use excessive cpu cycles and in turn cause the phone to use a lot of battery i'm not sure if
that's resolved yet as they haven't mentioned it but we'll know after a few days when we see what
the battery's like so that will give us a better insight into that now there is a security update
in this update and you can see that yourself if you go to the apple security website and all you
need to do is scroll down so if you go to the security website you'll see the latest versions
here with mac os monterey 12.2.1 watchos 8.4.2 and ios and ipad os 15.3.1 if you scroll down you'll
see there's one fix and it has to do with webkit or what's the underlying code for safari and so as
you can see it says impact processing maliciously crafted web content may lead to arbitrary code
execution apple is aware of a report that this issue may have been actively exploited
to fix this a use after free issue was addressed with improved memory management and then someone
let them know anonymous anonymously that this was an issue so they've resolved this it's a security
update and patched a very critical issue the same thing has been patched on ipad as well so all of
those things are resolved in this particular update now as far as if you should install ios
15.3.1 if you're on a previous version of ios 15 many people said 15.3 was the best version as far
as overall performance and everything else with 0.1 you're getting a security update and a bug fix
so i would highly recommend it of course if you're having an issue with accessibility in the braille
display definitely install it however if you're on the beta i wouldn't necessarily roll back to this
version as we should have newer betas in a little while now as far as when to expect ios 15.4 beta 3
we can expect that probably next week maybe on tuesday or wednesday the 15th or 16th of february
with maybe a beta the following week so we could be on a one to two week cycle we're not sure yet
but if we're on a one week cycle we can expect the beta next week then another one the following week
with maybe a release candidate in the first week of march with the final release sometime in the
second week of march where we expect a new apple event on march 8th so it looks like that could
be the time frame they haven't announced this publicly but it does seem very likely
now as far as battery life in ios 15.3.1 well like i said earlier it will take a few days to know
what that's like and battery life typically was pretty good for most people on 15.3 over 70 in the
follow-up video that i did said that it was better or the same as previous versions so it does seem
to be doing well for them as far as what you can expect i wouldn't expect a change however after
installing the update the device will have to do things such as index in the background that will
use some power and it may not be great battery the first day but it improves over the next day or two
so we'll be checking that out over the next couple of days also the device was quite warm after
installing the update in fact it's still a little bit warm i wouldn't really be concerned about
that as it's typically doing a lot of processing and things in the background so that's typically
what's going on after you install an update if it doesn't ever cool down maybe do a hard reboot but
the other devices i have here are nice and cool so i wouldn't worry about heat or anything like that
but the 13 pro does seem to be processing quite a bit as far as overall performance
performance is nice and smooth pro motion seems to be working well and i haven't noticed any problems
whatsoever it seems nice and smooth and as far as on older devices as well i wouldn't expect
it to be much different since it's just a bug fix and security update typically you're going to see
about the exact same performance when it comes to that and so that's everything in ios 15.3.1
some bug fixes and security fixes and not a whole lot more we expected this but we expect many more
features with 15.4 and later on at wwdc 2022 which should be around june where we see ios
16. so typically that's where we'll see a ton of new features or maybe visual changes as well
but if you found anything else in this particular update i'd love to hear from you in the comments
below and of course if you'd like to get your hands on this wallpaper i'll link it in the
description like i normally do if you haven't subscribed already though please subscribe and
