what's up guys my name's Brandon and as expected apple released ios 15.2.1 today just about a
month after the release of ios 15.2 so this is a public release so it is available to everybody
and along with this apple did also release ipad os 15.2.1 but that's it there was no new watch os tv
os or macOS updates today and we'll explain why in just a moment so let's start off with the size
of this update so you can see here it came in at just under one gigabyte on my iphone 13 it came in
at 970 megabytes and you'll also notice that there are no release notes here this is the first time
i believe at least that i've seen where apple did not include anything with the update there are no
release notes there's nothing here it just shows the update number and the size and that's it so
very very strange but let's go ahead and check out the build number of this update so if we go
to our settings here general about 15.2.1 we could see the new build number here is 19c63 and if we
go down to the modem firmware you can see that is now 1.32.09 all right so now what's new here
with ios 15.2.1 and as always with a double point update like a 0.2.1 this is going to be
a bug fix update to patch up some of the issues that were still remaining on ios 15.2 and the
first one you can see apple mentions here is that messages may not load photos sent using an icloud
link so if you went to a photo and then you went down to copy icloud link right here and
you sent it to somebody it would just simply not work sometimes on ios 15.2 so i experienced this
i don't do this very often but i did experience that on 15.2 and thankfully now that has been
fixed so when you send a message with an icloud link they will load properly for the other person
we also have a fix for carplay so carplay has been extremely buggy in ios 15.2 for a lot of
people but now there is a fix for the third-party carplay applications not responding to input so if
you ever had issues with input on third-party applications like it just would not respond
to your taps on the screen that has been fixed with this latest update so those were the only
two bugs that the apple mentioned were fixed with this update but there are a couple of other
things i wanted to talk about and the first one is that t-mobile just recently came out and said
that there is a bug in ios 15.2 that would disable icloud private relay for some users so
i'm not sure if this update patches this bug because apple didn't mention it at all
in the release notes or anything publicly but if you were not able to enable this feature before
try it again once you update to 15.2.1 and let me know in a comment down below if it is fixed
for you and if you don't know how to enable it just go into your icloud settings right here go
to icloud go to private relay and then enable that so some people were just simply not able to enable
this feature it was grayed out and then some people it would just turn off automatically for
so t-mobile did come out and say that this could be caused by having content filters on
but some of the users also did not have anything related to content filters enabled for their plan
or their device so it seems like this might be an issue on 15.2 that could be fixed with this
update but easily the most important fix in this update and really the reason you're going to want
to update asap is a patch to the nasty denial of service vulnerability known as door lock so this
is a vulnerability that works by changing the name of a home kit device to something with over 500
000 characters so it would then cause your iphone to completely freeze when you got back to the lock
screen and the only way to fix it is through a restore so if you didn't have a backup or anything
you would lose all of your data thanks to this bug and this vulnerability was recently published
online since it was reported to apple over four months ago and they never fully patched it
so thankfully this has been fully fixed as you can see from apple's security document published today
now this was the only security vulnerability that was fixed with this update so it's probably the
main reason that apple pushed out a 15.2.1 now as far as remaining bugs there are some people
still facing issues with ios 15.2 and i'm sure they are not going to be fixed with ios 15.2.1
and the first one has to do with our storage so if you go to your settings a general iphone storage
some people were still seeing issues with this just simply not populating the calculation up here
either not populating or taking a very very long time to show up their storage right there so again
some people would see an inaccurate number so if you only use 31 gigabytes some people would
see it say like 100 gigabytes so there are still some issues with the iphone storage right there
just not populating properly and again i don't think that's going to be fixed here with 15.2.1
something like that will likely be fixed with a 15.3 update and then some people are also having
issues where their siri voice will switch back to the default voice instead of the custom one
that they selected beforehand and i did also want to mention that we still did not get a new
watch os update so that charging bug affecting the apple watch series 7 users is still going
to remain until we get a new update for the apple watch which i would assume would be pretty soon i
don't think apple would wait until watch os 8.4 but i could be wrong we'll have to wait and see
what apple does to fix that charging bug now as far as the performance goes performance feels
about the same as 15.2 to me but it's still early on and gauging the performance takes a little bit
of time so i will report back in my follow-up video on saturday and i'll tell you guys if the
performance has improved any or if it's taking a hit or just how it's performing overall and i do
hope it's as good as ios 15.3 the betas because beta 1 felt amazing in terms of performance it
felt better than ios 15.2 the final release so hopefully 15.2.1 kind of takes a hint from the
15.3 betas although i doubt that because usually you don't see major performance improvements on
these double point updates but anyways as far as the battery life goes it's kind of the same deal
with battery life we're not going to be able to tell until a couple of days of using 15.2.1
but i will report back to you guys in my follow-up review on a saturday how the battery life has been
performing so now should you update to ios 15.2.1 and i say absolutely it's a double point update
so the likelihood of it causing more bugs than you had before is very slim those bugs usually
come with bigger point updates like a 15.3 might cause more bugs for you but 15.2.1 is most likely
not going to cause any additional issues on top of what you already had so if you want bug fixes and
of course an important security fix along with the possibility of better performance and a battery
life you should strongly consider updating your iphone or ipad as soon as possible all right so
now what's next for apple and the next update i believe is going to be the big one ios 15.3
and i would expect that sometime in early to mid february so this update is the one i predicted
to come in mid january back in december and it did come it came in pretty much exactly mid january so
i would expect the next update to be here within the next four weeks so that puts us sometime in
early february that is my prediction of course anything could change apple could do whatever
they want to do as they have pretty much all of last year but we'll have to wait and see and of
course i will keep you guys updated as always over on twitter so if you're not following me over on
twitter that link will be down in the description below make sure you follow me over there
and of course make sure you are subscribed to the channel so you see the update videos when they
do get published but anyways guys there you have it that is ios 15.2.1 a very minor update but of
course it does come with a very important security fix and some minor bug fixes as well if you guys
enjoyed this video i would appreciate if you give it a thumbs up and again make sure you subscribe
