Animation is definitely laggier on 4.2.2 than 4.1.2 - Did full wipe but no joy.

Wifi signal is stronger no question about it but.... Battery life seems to drain faster for obviously no reason ( 8 hours on battery after full charge vs 21 hours )

This is starting to piss me off coming from the Lumia 920, I am back to the Android lags nightmare.
[Xperia Z General] flakac:
Before update sound was more crispy but now I have feeling that basses are more distorted and music is less enjoyable. I am using Poweramp and I never got any issues with sound until now :L

Tried wipe, tried other roms, but still same :L

When I downgrade to .307, everything is ok again. I really like 4.2.2 but sound is important to me :L
[Xperia Z General] exekias:
It absolutely boggles my mind that we all have the same device and are all flashing the same FTF's and yet user experience is so varied.
[Xperia Z General] Xeon:
Welcome to the Android world.
[Xperia Z General] LitoNi:
Cause some people decided not to entire wipe their phone. Always causes issues. A major update should always do a full wipe to avoid any issues.

Best way and always work for me.

Back up files

Ftf flash and wipe everything

Factory reset (internal wipe) then repair it with pcc

Root and cwm

Its that simple
[Xperia Z General] Xeon:
I beg your pardon ? I thought I already said that I did a full factory reset.

You do realize that you don't have to root and cwm to get rid of the sluggish home screen performance don't you ?

I do not want to root. This thing should work with whatever stock ROM you have and a lagging animation nowadays is NOT ACCEPTABLE.

WE HAVE A F*KN QUAD CORE WITH 2 GIGS OF RAM FOR GOD'S SAKE and this thing is STILL NOT ABLE TO HANDLE THE DARN MENU TRANSITION SMOOTHLY.

Maybe an octa core or maybe hexadecagon processor with 64GB RAM will animate a basic phone home screen smoothly one day... and I am not really sure of it.
[Xperia Z General] LitoNi:
It's not the number of cores. Compare this with nexus 4, same chip same amount of ram, that tiny lag is the software. Nexus 4 runs smoother than any android out there.

If that tiny lag matters that much get a nexus 4
[Xperia Z General] dante501:
Not sure m speaker is loud. Headphones is a different story but there are apps for that. And I seems strange with ur sound. Mine seems fine did u check if u enabled the sound setting clear sound in the sound menu I'm xperia? It could be disabled.
[Xperia Z General] Xeon:
That lag was not happening on 4.1.2. If it was, I would have dumped the device the minute I got it.

The "tiny lag" you are talking about happened after the upgrade when everyone was expecting several performance improvements according to the changelog, not the contrary.

And you said it yourself, if another device with same specs is not lagging, that alone is a reason to complain.

I bet no one is enjoying some random tiny lags on a a flagship device.
[Xperia Z General] philipsim@live.com:
Then reinstall the apps manually? Because I wanna start fresh , even though I wiped everything while flashing the ftf, I feel that my phone is not fully wiped.

[Xperia Z General] Julianocas:
It's almost a test version... wait sometime for god sake...

The first 4.1.2 was laggy to for Xperia Z/ZL. Sony improved lots of things with minor updates, including stability and performance, with some UI goods...

Wait... report your usage and everything that looks a problem here or wherever you are, maybe someone from Sony is following this thread and checking all complaining we report, and maybe this helps everyone...
[Xperia Z General] Xeon:
Sorry but we are not beta testers...

Anyone care to explain what's this ? It happens that when I restart my device I lose 10-15% right away... That phone was put on charge for 4 hours and the battery couldn't last more than 6 hours. I was having 20 -28 hours battery life with average use.
[Xperia Z General] Gez77:
just calibrate your battery, the method can be googled.
[Xperia Z General] Haldi4803:
^^ i have the exact contrary problem.
[Xperia Z General] dante501:
A nexus runs pure stock android where Samsung HTC LG Sony Motorola all use there own software on top of android and all of them aren't as smooth as pure stock android but most of the time somewhat more user friendly them pure stock android. So really no device runs as smooth as an nexus period. Is because the pure android is just the really best optimized software. And my Xperia Z doesn't lag at all. Just to ur info. Still it isn't as fluid as a nexus. And again no device is as smooth as an nexus. Or should I say no android device is as smooth as an nexus.
[Xperia Z General] Julianocas:
I know, but not everyone is perfect, including brands...

For avarage user (almost everyone excluding XDA, lol), they don't even care about this and the Phone is fast as hell, even without updating after getting device out of box. I have a friend that have the ZL and he bought almost two weeks before me, and he have the same FW until now, probably the first one...

Give Sony a try, they are years ahead with user interaction, comparing with Samsung for example.

Report everything you see that have to change, in your opinion, maybe someone read it and make this changes... ;)

About your question...
[Xperia Z General] Xeon:
No offence but.... You do realize that the main point is that the device was smoother prior update. Don't you ? I don't know about Nexus 4 and I am not implying that XZ should run faster than whatever device.

To sum it up... 4.1.2 was noticeably faster than 4.2.2

Take it as a feedback whatsoever, but I tried to wipe it, repair using SUS and manually install everything, nothing helped.

The lockscreen also lags like hell when the device boots but I can live with that.
[Xperia Z General] LitoNi:
Do you even know what you're talking about? Like I said, it's Sony's software nothing to do with the hardware. No such guarantee did any manufacturers said their "flagship" is lag free. They never said newer models are better than the old ones either. If you want to compare then compare cameras and flash and software and everything, durability. For gods sake, it's only an update and you guys expect so much from it. Like it's a new world or something.

Every device lags, s4, htc one, optimus g, lags. Only nexus 4 or vanilla or cm rom are "close" to no lag. If you want to dig deeper, androids script is old as hell compared to any other oses out there. It is considered out of date.

Sony 4.1 was more laggier than 4.2. There's lag every where. I don't know what you've installed in your device, but if you cant even accept lag then go get yourself, an iPhone.

It's not easy to do any of these, got so much demands? Why don't you try doing it yourself and make it lag free. If you cant then stop complaining like a kid, you dont always get what you want. Appreciate what others do for you, don't take things for granted.

Peace.
[Xperia Z General] rohit25:
Any one has any idea which app can I use.FOR permission management on my stock 4.2.2 rooted
[Xperia Z General] Xeon:
For someone who has been following this forum for the last 10 years... I certainly do.

You don't have to defend your point. As said, I am posting my observation. Some people can spot it some others can't.

Check Sony forums, I'm not the only one complaining eh ?
[Xperia Z General] asuna88:
Flashed spanish 4.2.2, did full wipe before restoring using TWRP, so far so good.

Launcher definitely smoother than 4.1, only noticeable lag is the lockscreen (when waking the device), its slight so not a big issue to me.

A little confused about how the new filesystem works though, with the emulated/0 folder. Some of my apps couldn't locate language packs (swiftkey) and had to re-download them. I assume its due to this? I almost screwed up by deleting the '0' folder, but some other thread warned not to do so ;)
[Xperia Z General] LitoNi:
Lol, okay being here is better than Sony forums.

Those guys ranting there has no clue what android is.

People here are educated lol :)
[Xperia Z General] nizarnoor:
My Gallery is super laggy. :(

And the rectangle boxes/borders that flash when we are about to unlock, they really annoy me. I want the old lockscreen back.

Root your phone and install litoni's mod of the small app launcher

[Xperia Z General] arttree:
totally agreed with your point. Sony forum is for those know NUTs shouting and wait a few day shout at the forum admin agian ask why there aren't no solution or update. those are people don't google to find the tips. This is common at any OFFICIAL phone manufacturer forum. wheather is samsung, lg or htc happen too.

and the best thing is, there are known to whole world that a lot of those who complain are not REAL owner/user but are PAID by competitor co to disgrace other party phone.

But at XDA forum you PAID by other competitor user are mosty WELCOME to blast or troll the post, only difference is that XDA member are smarter to know what correct what is not.

PEACE. :)
[Xperia Z General] Xeon:
You are not on gsmarena website you know... you don't need a degree to spot the lag after upgrading to 4.2.2 stop kidding yourself.

The main difference between XDA and other website is that people here listen and try to support and not defend blindly a point

like on some other websites.

I already said my device is slower after updating, if someone has any clue why, which possible application or process could be causing it whatsoever, that'd be great as I'm trying to find out.

IF you don't know, stop arguing and enjoy your real real device.
[Xperia Z General] DeathlessOne:
Guys, please stop this. Don't get this thread locked. As for the lags, please post a request to Sony and wait. They'll be able to help us with an incremental update or if possible move to custom rom's at the moment. Because some of them face and some don't, it's impossible to pin-point the exact cause. All we can tell is to wipe/reset/repair. If it doesn't work, then we should be waiting or you can also degrade to .307 for the moment. Thank You!
[Xperia Z General] LitoNi:
lol we're all chill, just that some of us had a really rough day.

yo Xeon, didnt mean to take it out on you. No hard feelings. :angel: <--- and thats one thing different about XDA and other forums.

Did you installed all the previous apps from 4.1? I found out most of my previous apps were not compatible with 4.2, some of them even runs in the background with like 30-40+ mb. I had to uninstall them it was too ridiculous.
[Xperia Z General] Xeon:
Yo dude, actually yes but most of them are not running in background.

What I have in Background is Whatsapp, Viber, Tango, Sync.ME, Facebook Messenger and Csimple VOIP only.
[Xperia Z General] sidneylopsides:
Mine was smooth after an upgrade without deleting data, but the battery has been terrible. Everything is noticeably smoother, the screen feels more responsive.

Due to the battery is re-flashed with a full wipe. So far it charges quicker, so that's a good sign. I'll see how it goes today.
[Xperia Z General] flakac:
My speaker is OK,better than before actually,but I am experiencing poor quality issue on my headphones :L
[Xperia Z General] primularosea:
my XZ was smooth, and no complaint here :)

it just that camera & Walkman shortcut beside clock on lockscreen is gone, while on my friend's XZ it appears (it wasn't there before or so he said)

is it just me? my lockscreen looks.. empty lol, thank god there's dashclock, but still curious about that issue :D
[Xperia Z General] DeathlessOne:
Walkman will appear when playing music. Camera shortcut is on the right lock-screen. Swipe right to see it.
[Xperia Z General] primularosea:
yea I know, but it just feels empty and I'm curious of the behaviour lol

as I said, on my friend's XZ it suddenly appears while on mine it disappear when updating from 4.1 lol
[Xperia Z General] exekias:
Nope I noticed it get better
[Xperia Z General] plonkersaurus:
Mine doesnt :(
[Xperia Z General] dante501:
Like I said it doesn't on mine everything seems smoother then it did on 4.1.
[Xperia Z General] C1emen7s:
Mine was the opposite. Became a bit slower, but the battery life is incredible by comparison. Yesterday it dropped 30% over the whole day (14 hours) with wifi and 3g constantly on, the screen on and off through the day, while before, it would go from 100 to about 10% over the same timeframe and the same sort of usage.
[Xperia Z General] msc3169:
C6602 owners experiencing lags when flashing C6603 firmwares perhaps?

Atleast thats the case with me I believe.
[Xperia Z General] bigbamboo5:
That'll change the type of screen lock - I want to keep the lockscreen, but lose the everlasting 'swipe up or down to unlock' message, without having to root. Any ideas?
[Xperia Z General] kingvortex:
It appears that [MENTION=4628622]LitoNi[/MENTION] has removed that prompt from the lockscreen.

I really hate this new lock screen.

It looks all messed up just to add a widget screen.

I wish I could keep the old one. :(
[Xperia Z General] dantistruct:
Works really well

Have yet to feel my device reach the heat that it used to in previous firmware updates.

Camera is awesome now... well even more awesome than .352.

Really smooth to move around my phone and switch between apps and recent app section, only place where I feel a little bit of jitter is in the album app when I 100% zoom on a picture and try to pan around.

What I'd like to see in new update, Triluminous color tuning of XZU being ready for our device and this will make this phone unbeatable and just too awesome.

Kudos to Sony for this update!

Can't pair my XZ to my car bluetooth system since upgrading to 4.2.2 - both recognise eachother, car asks for a PIN which I have to confirm on the phone, but after doing that nothing happens.

Also some apps (BeehiveIM being one) are force closing as soon as it's run. I could clear the app's data, but I can't live without bluetooth not working on my car anyway, so might downgrade...
[Xperia Z General] Gez77:
yeah yeah if you like perfect transitions without microlag, go get yourself an iphone
[Xperia Z General] cordonbleu:
Iphone also laggs. Difference is that it runs

smoother

Those who have a very fast smooth transitions... Which ROM are you on ? mine is 4.2.2 10.3.A.0.423 GREECE.

I was on Generic UK and changed customization number to Generic ES and updated via PCC.

No lag issues here.

Notice the battery percentage is dropping rather quickly but I will give it some time for google services to settle as it is using more battery right now.

[Xperia Z General] doghous:
I got my update about 2 hours ago via the "Sony Bridge for MAC" (unfortunatelly I have a macbook now as a corporate laptop and my gf has kind of "taken over" my windows laptop :P )

I run the update (I have an unbranded one bought in NL so I had an official update) from that, didn't lose any data but the mobile does not charge via the -non origina- dock connected to the laptop. Also I noticed that it can't connect to one of the wireless networks in my office (EAP authentication etc.) whereas it works in simple WPA wifi @ home.

I am backing up everything both from the backup and restore app that it had in the mobile and from the Sony Bridge and I will do a full restore/re-upgrade with wipe via the Sony bridge app.

I hope it will solve these issues, else I'll start experimenting with the FTF via a Windows Virtual box.

Once everything is solved, I'll come back with my short review on the new version.

I just don't understand why they removed the screenshot from power menu. Small app clip manger doesn't work, which leaves you only to use power button + volume down key.

While it is more inconvenient to use than the old power menu entry, the clip manager does actually work. You need to look in the Notes app for your screenshots.

Not a very intuitive solution from Sony. A strange design decision indeed.
