Since my last post I had lots of home screen redraws, frequently when I use Chrome for a little bit and then I want to switch to another app.

Checking under "running" apps I see that while the system redraws the home page, several apps are restarting.

That looks an awful lot as the memory leak problem of Lollipop, (allegedly) resolved in 5.1.

This pisses me off a lot. :(
[Sony Xperia Z Ultra] hansip87:
With Battery Life more than stellar, i think i can cope with it for now. Maybe you need to try those Xposed Android 5.0 memory leak fix though.
[Sony Xperia Z Ultra] frothe3:
I have a had a few crashes, where it becomes totally unresponsive. I just chalk it up to OS update. Otherwise, it feels like a new device.
[Sony Xperia Z Ultra] fastest83:
I haven't tinkered with root and stuff yet, I don't feel the need right now.

Anyway, Chrome seems to be the most hungry app of all.

But even when the home screen redraws and apps are restarting, free ram is always a bit under 500Mb, so I really don't understand what's happening here.

My Nexus 10 never redrawed the home screen. Not on 4.4, not on 5.0, not on 5.1.
[Sony Xperia Z Ultra] Con500:
This is the main issue for me also. Its a pain, it is happening so frequently and is making multitasking practically useless since most of my open apps are Re-started.

It is just makimg making my Zu feel overall sluggish.
[Sony Xperia Z Ultra] belzedj:
Anyone can upload the camera apk? Thanks
[Sony Xperia Z Ultra] fastest83:
This is starting to piss me off A LOT.

Memory leak gets SO BAD that every single app restarts, even those who shouldn't, like Android Wear (causing the SW3 to disconnect and reconnect when it restarts), or apps which are supposed to stay alive when opened (like Dormi, which HAVE to stay open because it functions as a baby monitor, communicating with another phone connected via the same wifi ap, and is killed by the damned bug, and I don't hear my kids when I have the headphones on AND THIS IS REALLY A PROBLEM at night).

This shouldn't be happening AT ALL.

Now that people say this, I didnt now it was a memory leak. THe only thing I can say, wow.

This is like programming 101, dont do memory leaks. Those guys in google are retarded.

Well, if someone has a rooted 5.01 from sony, does xposed work/help?

This is serious issue,i really dont want to switch to CM (Dont know if the camera works), but this is pretty much a greenlight to **** off there. This is terribly serious.
[Sony Xperia Z Ultra] hansip87:
Seeing that Sony doesn't do any screen lock animation, i doubt that the xposed workaround will work. Sony is aware about the issue so i think they eliminate the lock screen animation entirely. but CMIIW, if it does work, count me rooted in short time.
[Sony Xperia Z Ultra] tsiros:
anyone else noticing the wifi hotspot silently failing after a random amount of time, more frequenty when doing heavy data transfers?
[Sony Xperia Z Ultra] fastest83:
Agreed. This shouldn't have happened.

I mean, this thing could happen to a newbie, but Google? Come on.

What's worst is that once THEY fixed it we'll have to wait months for Sony to follow suit.

I honestly don't want to go back to KitKat just to root, I don't care.

I'll remind myself to restart the phone once or twice a day and that's it.

Until I'm changing phone that is.

uri to rooting c6802 GPE

om, have you root your c6802 xZU? I am struggle to find it in this forum. I want to root my c6802 GPE Stock Lollipop (5.0.2). I don't care the warranty, so I unlock my xZU at the first day I received the xZU. Now I am looking for thread for root it. All rooting thread that I search is always not for c6802 GPE.

Many thanks

I still have this wierd WiFi issue:

Signal is OK but no Internet access - I turn airplane mode ON = WiFi goes OFF - I turn airplane mode back OFF = WiFi still OFF!, so I restart my device but screen goes black and takes long time to restart or till I force it to. This problem doesn't happen with all connections though.

Any Ideas on that? I tried factory reset, and PC companion fix. But no luck.

By the way first time I flashed lollipop by flashtool, Ukraine FTF, tho my device is MEA could that be the problem?

Thanks.
[Sony Xperia Z Ultra] Doom Slayer:
For me camera is not worknig.

Not even focusing.

Looks like it's unable to write to memory.
[Sony Xperia Z Ultra] martin132014:
For me like everyone else is memory leak issues...screen redraws all the time, app restarting even though just went 2 second to switch to another app and back...phone heating up faster...battery drain is worst in here....and the camera when indoors is worsening...and performance is slow..take nearly 3-5 second to open the recent app menu and any other app for that matter...other than that.....i very much like it....don't wann go back to kk and hoping a fix will came out....

[Sony Xperia Z Ultra] fastest83:
Can I just say that this memory leak bug freaking piss me off??? Chrome (or maybe Android Web View, I don't know if the problem extends to other browsers) is being a HUGE brick in terms of memory consumption, you can sense that because when I browse some site for more than 10 minutes every app and service restarts in the background.

And by EVERY I mean EVERY SINGLE ONE. Even the ones that are NOT SUPPOSED to, like bluetooth, for God's sake.

My Smartwatch 3 keeps disconnecting and reconnecting every 2/3 minutes while I'm browsing, and randomly every x hours due to the memory leak general problem.

This is serious stuff, really something that should NEVER happen. NEVER.
[Sony Xperia Z Ultra] raundown:
I'm seeing the random freeze and reboot again. I was able to get rid of that by turning off location based wifi feature in power management. Now that the feature is missing I don't know what's causing it now
[Sony Xperia Z Ultra] BragaisG:
Regarding the memory leak issue, this is a known problem for Lollipop 5.0.1 and has been fixed on 5.1.x

I am even surprised that Sony used this version for their phones and not 5.1.x but I was thinking that maybe they have fixed the leak issue when doing so... but apparently, not from what we are observing...
[Sony Xperia Z Ultra] fastest83:
Wanna know the funniest thing happened just a second ago? I was reading a review on Chrome, highlighting the most interesting points, and copying them on the "note" small app.

Suddenly, after like 30 or so highlights, the small app suddenly closed (read: crashed) without saving.

WELL DONE SONY&GOOGLE, WELL DONE.
[Sony Xperia Z Ultra] PDesire:
I read all your posts, and I am a little bit wondered

The issues what you have, I don't have this issues WTF

On first boot to system all works fine but not so good, after 10 minutes, my phone crashes and reboots, after reboot, all works very fine without crashes,bugs,issues and fails:)

Have I a magic phone or why does all work perfectly ?
[Sony Xperia Z Ultra] tsiros:
the recent apps screen is stupid...

it is very slow and not practical.

first of all, it takes two to three seconds to appear. that's slower than hitting home and going to the app drawer where you have all your apps. I also have remapped home button to open the app drawer so i just double tap the home button...

second, but equally important: half the screen is wasted displaying the *current* app... which you can get to touching the "recent apps" button again.

second, it only displays two or maybe three recent apps you can get to easily without scrolling and without aiming with a sniper scope

if i have to wait for it to appear and then to scroll to find the fourth (or worse, an older) previous app, then it is faster to open the app drawer

i would much prefer the soft button area on the bottom of the screen to have back/home/recents on the left side and five icons for the four or five recent apps as icons on the right. much faster, one less tap, no wasted resources in recent apps (all those bitmaps...) and you don't have to wait for it to appear to tap what app you want.
[Sony Xperia Z Ultra] the:dodger:
Flashed rooted stock 5.0.2 created with prf.

And I am very happy. Battery lasts way longer, looks like energy consumption especially during sleep mode is a lot lower. Phone feels generally faster and more responsive. Have no problems till now, just once phone crashed and rebooted, but also had this on KitKat once or twice. Recent app screen opens instantly. More free ram, had low memory warnings in the tasker log, these are gone now. Also flashed xposed alpha with no problems so far. Only thing is that the sound volume is very low, will flash a sound mod next. Camera functions normal, but I don't know if the quality changed, I just don't use it very often.

So far an overall positive experience. Well done Sony. And I just read that the z line might get a 5.1.1 update in July or August :thumbup:
[Sony Xperia Z Ultra] hansip87:
Or you could use my Fast App Switcher Small App ;)
[Sony Xperia Z Ultra] shadowcore:
Because of the memory leak issue of Lolipop 5.0.X, I went on and unlocked the BL, reflashed 4.4.4, rooted it and installed a custom rom.

Until/If sony updates the ZU line to 5.1, I think a custom rom serves me better.

Incase anyone is interested:

http://www.gsmarena.com/sony_xperia_z_series_to_get_android_51_lollipop_in_august-news-12185.php

I wonder if "Show Stopper" actually means memory leak.

So, if they update the ZU to the 5.1, ill be staying with my custom rom. In fact, if everything, from GPS, WiFi works fine in Resurrection rom, im currently at, I actually wont find any reason to go back to the stock firmware.

Eventhough sony proprietary apps are nice and the Sony skin isnt bad at all. In fact, one thing I can say for certain is that the sony skin, even though almost stock android, has a better look and colors than stock CM.

Havent tried stock CM themer yet.
[Sony Xperia Z Ultra] martin132014:
Does major lollipop issues on 5.0 still exists in 5.1....the memory leak issues is driving me crazy....is 5.1 still the same as 5.0....
[Sony Xperia Z Ultra] hansip87:
Seeing this thread it looks like Sony was taking time to ensure that 5.0.2 ColorFade issue is non existent. So you don't have to root to fix the Memory Leak. But apparently Google has a lot of issue with lollipop i guess Sony can't do code digging too much to meet the update schedule.

The point is, if you can patiently wait for 5.1 release, then wait for it. If you can't old Kitkat version will serve you well. Sony has been trying as good as it can do to negate what Google have poorly coded into Android
[Sony Xperia Z Ultra] Andre Verissimo:
The new 14.5.A.0.270 is here.

The colors are really toooo washed and the device is working way hotter than when I had 4.4.4. Who knows the 5.1 will be a better version?

pt_BR:

Instalei a segunda versão do Lollipop (270). As cores estão lavadíssimas e a máquina está bem mais quente do que quando tinha o Kitkat 4.4.4. Recomendo esperar o 5.1.
[Sony Xperia Z Ultra] Jecmenn:
It must be probably problem on your side because i have .270 too and my device is only slightly warm during heavy gaming. Yeah i hope that they fix all present bugs in 5.1. Well if we get 5.1.
[Sony Xperia Z Ultra] nasgadth:
after i upgrade to lollipop, some of my apps got washed out color, like low constrasty or some sort, the notification bar too, when i got no notification the color is washed out, but when i got one it's alright. After some googling i found out the problem is on optimized backlight "feature" on z ultra, but i can't find it anywhere, it seems they removed the option after that update wayyyy back then, how to fix thisss?? this is really annoying

oh and yeah, i reseted, formatted, and even now running other region ftf, but still
[Sony Xperia Z Ultra] gideonMorrison:
The only gripe I have is with a bug that a couple of times a day when I press the home button to go to app list, it disappears and takes seconds to show my apps again. Really annoying. Started with Lollipop.
[Sony Xperia Z Ultra] shadovraven:
To people who have memory leak problem on lollipop. Did you make a hard reset after OTA? Just curious.
[Sony Xperia Z Ultra] frothe3:
All I know is that sometimes the phone crashes and reboots without warning ⚠, sometimes doing it while charging, so heat ? might be an issue.

Another problem I have is with emails, some load, others take too long to load. Drives me insane .
[Sony Xperia Z Ultra] kientrongtran:
Yes I did reset after upgrading to build 270. The situation seems to have improved a bit with this build. However, I still rely on Ram management and Memory lock apps to prevent force close on designated apps like Walkman or Nova launcher, now the situation is a whole lot better.
[Sony Xperia Z Ultra] thegidz:
Anyone here who got upgraded from 242 to 270 already? I want that "Close All" button on the task manager. 242 doesn't have it.
[Sony Xperia Z Ultra] sw6lee:
So some people on this thread said lollipop is running great while others say that memory leak issue is present and is really annoying. Which is correct? I am worried about installing lollipop although i love the look of it.
[Sony Xperia Z Ultra] xb91:
Great but ...

I love the new Android L on my Z3 Compact so i was very happy to finally see the "New software update" notification on my XZU. So installed it right away just to realize that The lollipop version for the XZU is missing some very important stuff ! The whole point of buying this device was because of the small icons on the BIG FHD screen . But now there is no option to change the home screen grid ( like in KitKat ) which is a VERY BIG DISAPPOINTMENT for me personally. Not to mention that they didn't implemented the Smart Call handling, or smart the orientation function nor the Super ViVid mode. it's like Sony wants to keep the ZU to the year 2012 when it was introduced. So if you want all this cool stuff you need to buy a newer Xperia device.

I am totally pissed ! I had all this things on my Kitkat version. Now i have to hope for some developer to port them for our XZU devices again.

To summarize:

- "Change home screen grid" setting is removed ( which means you get huge icons on your screen which is a total waste of space).

- No Smart call handling feature

- No Super ViVid mode.

:eek:
[Sony Xperia Z Ultra] kientrongtran:
If those are all the issues you find annoying with lollipop update then that's a good news actually because this is Xda lol

Smart call handling/ smart rotation / smart backlight plus Super vivid mode mods have been ported to z1/zu for quite a long time now: they are available from here http://xdaforums.com/crossdevice-dev/sony-themes-apps/port-smartcall-handle-smart-backlight-t3084285 all these features work swimmingly.:good:

about the icons, the new version of Xperia Home allows you to change icon size (small, big) similar to the grid found in kitkat. If you care to install xposed and the little module called Xperia Xposed then the customizability goes even further with icon pack support, different animations, every icon size / grid possible, add more tiles to quick settings drop-down, change number of tile rows in quick settings, center clock in stt bar, hide apps in app drawer.
[Sony Xperia Z Ultra] fastest83:
Can I point out something? It seems to me that the device crashes/stalls A LOT with location services on, and seems to be (almost) good otherwise (some redrawings of the home screen still happen).

I noticed the GPS icon showing up a few times when the device became unresponsive, so I tried disabling it altogether, and it seems to work so far.

Try it out and tell me if it works for you too.

I recall that my wife's Xperia Z had problems for a while with battery draining due to the location services eating system memory, and the problem could be solved (temporarily) by disabling location...
[Sony Xperia Z Ultra] raundown:
Just updated to. 270. What's up with the oversized icon? Fugly as ****. Is there a way to resize them?
[Sony Xperia Z Ultra] DRKMTTR:
try to read this [LINK]
[Sony Xperia Z Ultra] xb91:
Really ?

Is This for real ? OTA updating will keep the "Change Home grid" option in Settings ? This sounds ridiculous ...

I updated through PC Companion and i don't have it.
[Sony Xperia Z Ultra] fastest83:
I just updated through Sony Bridge for Mac to .270 and it changed the icons for big ones, but the grid remained 6x6...

And you know what, I actually like the big icons :D

But maybe that's because I already was used to Google Now Launcher...
[Sony Xperia Z Ultra] raundown:
5 x 6 *
[Sony Xperia Z Ultra] fastest83:
Ehm... no.

It's 6x6, unless you count the dock, then we have a 7x6.

Short review

I finally decided to upgrade to 14.5.A.0.270 and here's my short review. I installed it using Sony PC Companion and did hard reset afterwards. I'm using it for few days already and I can say that it's actually worthy upgrade over kitkat.

What i like:

- battery life, it's better than on kitkat, i'm getting more SOT and also more standby time. Stamina mode is more robust now and also has extended usage which finally allows to reduce some battery drain during extensive use (by reducing screen refresh rate and disabling screen enhancements). There's also additional power saving mode hidden in battery usage menu, which restricts performance and can be enabled when battery level drops below 15%,

- it's smoother, consistent and polished, overally it looks better in my opinion, it's very close to stock lollipop and has silky smooth animations, I haven't experienced a single lag with it. Kitkat was already excellent but this is even better,

- google apps (maps, play and such), works much better with lollipop onboard, on kitkat they were pretty choppy compared to what they are now,

- better memory management, there's more free ram available and multitasking is better than on kitkat,

- heavy 3d games are smoother, I tested both Dead Trigger and Asphalt 8 and the framerate is much more stable than on kitkat. Asphalt 8 was smooth but kinda jerky on kitkat.

What i don't like:

- sound enhancements are available only for Sony music app, they don't work with third party apps like MixRadio or Spotify (and they did on kitkat),

- bigger icons on home screen (and they can't be changed), i liked the small ones much better.

[Sony Xperia Z Ultra] globiboulga:
I positively hate those big icons. It's geriatric heaven. Someone with bad eye sight must have ticked that one off at Sony. But why they don't give people options is beyond me...

Looks like I'm going to have to go back to Nova Launcher or something.

Ah, Sony, Sony, how can you continuously get it so wrong?
[Sony Xperia Z Ultra] saurabh_badhwar:
I'm not liking the large icons that appeared in .270 update. Atleast they should have provided us with an option to change the icon size
[Sony Xperia Z Ultra] saurabh_badhwar:
One bug I have experienced After upgrading to. 270 firmware is that the priority interruption aren't working anymore.
[Sony Xperia Z Ultra] thegidz:
Got build 270 last night. I'm actually not worried about the "large icons" myself because I use the Google Now Launcher because that's what I've been using on my other devices before getting a Z Ultra.

[MENTION=284074]Saurabh[/MENTION]_badwhar, what doesnt work with you regarding priority interruptions? Maybe it's the app that is the problem.
[Sony Xperia Z Ultra] saurabh_badhwar:
Before 270 whatsapp notifications were only showed for the starred contacts when the phone was set for priority interruptions but now no matter what the notifications continue to come.
[Sony Xperia Z Ultra] Flaco05:
Upgraded to build 270 a couple of days ago, and I have noticed the battery life has taken a big hit. Anyone else experiencing this?
[Sony Xperia Z Ultra] n_boy86:
absolutely lovbe the big icons, in grid on kit kat and now stock lollipop :) when the new xperia home comes if it comes to ultra then the option is there to change small/ large icon for u , or root then u could remove big icons :) :), some thing i dont like with lollipop

the quicksettings is much nicer and ui look in kitkat , and also all the apps shown in the lockscreen, i want to could disable them :/; so the new lollipop which popped up to day is better then the first 242, to 270 ? . , i havent update yet cause i like kitkat , [MENTION=4429993]shadovraven[/MENTION] regrds
[Sony Xperia Z Ultra] saurabh_badhwar:
After update battery life has been improved for me
[Sony Xperia Z Ultra] Flaco05:
For some reason, I find myself having to kill more background apps on a more frequent basis than with the previous build, even when the phone is idle.
[Sony Xperia Z Ultra] saurabh_badhwar:
Here is something will recommend

Go to storage and clear the cache.

If that doesn't work do a factory reset.

This worked for me. Hopefully will help solve your issue.
[Sony Xperia Z Ultra] zubeedubs:
is it just me or does anyone else have problems with freezes and random reboots??? it happens 1/2 times a day even if idle...
[Sony Xperia Z Ultra] frothe3:
Happens to me quite frequently, very random. Especially while using the Clean Master app, while doing a cache cleaning, or shutting down apps. Other times, when it is unresponsive, it crashes, then reboots.
[Sony Xperia Z Ultra] raundown:
I have this even when I was still on kitkat, but turning wifi based location off solve the problem. However this feature is not in the lollipop. I suspect there's still memory leaking in the 270 causing it. CPU isn't overheating in my case
[Sony Xperia Z Ultra] saurabh_badhwar:
Happens a few times and in no specific pattern. The problem was there on kitkat and is still present in lollipop. No specific solution.
[Sony Xperia Z Ultra] shadovraven:
I'm using .270 intensively for almost 2 weeks. I haven't experienced a single reboot, freeze, crash or anything like that. Didn't had that on kitkat as well, on 3 different ZU's. So problem must be on your side. There's also no memory leak in .270 as it has been fixed by Sony.
[Sony Xperia Z Ultra] fastest83:
Source where it clearly states that they fixed the memory leak bug on .270?

Because the home screen constantly redraws, apps crash in the background, multitasking is difficult if not impossible on any app.

It is actually ****tier and ****tier until you reboot and then it's fine until it gets stuttery again.

Sometimes when I push the power button it seems it's taking a screenshot too, "flashing" the screen...

I might have to reset back to factory settings and start from scratch, and maybe unlock the bootloader while I'm at it.
[Sony Xperia Z Ultra] shadovraven:
Here you go: http://xdaforums.com/crossdevice-dev/sony/clarification-xperia-lollipop-fix-t3087240

I don't have home screen redraws, no apps are crashing in the bacground, multitasking is actually better than on kitkat, so is the battery life. You guys need to learn that you need to do hard reset ALWAYS after upgrading to newer android version. That would reduce lollipop whinning post to almost 0.
[Sony Xperia Z Ultra] fastest83:
I guess you're right and I'll admit I've been lazy not to do it before...

Let's see how it goes from there. ;)
[Sony Xperia Z Ultra] raundown:
It varies. Every users use their phones differently. If you play graphically intenseive games for example you ll notice more. Apart from that there's the quality of components in your phone as well. The quality isn't identical despite of the same model.
