Yeah. Says up to date.
[Xperia Z3 Compact General] dark.blue:
ahh... thats why... i thought im getting digitizer error...

thx for the enlightment. [anyway, reboot seem fix the problem temporarily]

have you tried Factory Reset?
[Xperia Z3 Compact General] RaXelliX:
Wow i did not expect this. I've had this problem ever since i got my Z3C and installed all my apps. I always thought this was caused by a security program (or setting) and temporarely freezing all user apps fixed the issue so i figured it had to be because of a user app but i did not think about connection to brightness adjustment...

Thankfully i worked around this with an xposed module already (XInstaller).

I'm on 5.1.1 and my double tap to wake works the same way it always has... Don't have to do anything with the phone, just double tap the screen and it's alive...so I'm not sure what's different for you....
[Xperia Z3 Compact General] jarayn:
I don't like tap to wake as it always wakes up in my pocket for some reason.

However, it works exactly the same as before, kitkat, 5.0 and 5.1 are all the same.

Somerthing else is wrong with your phone.
[Xperia Z3 Compact General] :
When is a factory reset needed, before or after updating firmware?
[Xperia Z3 Compact General] RaXelliX:
When coming from 4.4 then before. When coming from 5.0.2 - not required unless you have major problems after upgrading.
[Xperia Z3 Compact General] clouds5:
When the phone has been in sleep and sitting on a flat surface with no movement it sometimes doesn't work. Then you have to move or pick the phone up first to make it work. See, if I wake up in the night and double tap to check the time it won't always work.

That wasn't the case with the initial kitkat firmwares the ones with which the phone launched.
[Xperia Z3 Compact General] najodleglejszy:
it's an intentional Android behaviour. Lux and other apps like this are basically screen overlays. Android doesn't let overlays work in the install screen, because it could potentially allow installing malicious software (for example, it could draw over buttons so that you'd think you hit Cancel when you in fact would hit Install). you just need to add Package Installer to the list of exclusions in Lux settings.
[Xperia Z3 Compact General] SyntheZ:
Of course not I don't have root so I will lose all my data. I believe there is a less damaging way to fix this issue.

Well i dont use lux. In my case it might be Llama.
[Xperia Z3 Compact General] Super2020:
Hello,

I'm on stock, not rooted 5.1.1 since 4 days. I have encrypted my phone (using the secure android encryption stuff) since 4.4.4. After upgrading to 5.0.2, I had no noticeable issues but now, everytime I switch my phone on and off, android is optimizing my apps (I have 245 of them). It takes a hell of a time. It does not happen when I reboot, just power off. I have done my update through OTA.

I did not move any app to SD card (that I know of).

(I wanted to clear the cash, but I can not reach the recovery mode... How can I reach that ?)

Does anyone have same issue ? Is there a fix ?
[Xperia Z3 Compact General] ajgftw:
hmm, I hadn't noticed my phone behaving the same after it has been sitting for a while, but I will pay more attention in case I'm just not noticing. I just haven't seen any other users in this or other threads mention the problem your having.

with my pevious phone the LG G2 which also had tap to wake I know that if the cpu speed during deep sleep were too low it could create lag waking up the phone. are you using stamina mode or any other battery saving apps that might be lowering the cpu clock?
[Xperia Z3 Compact General] Rodi_21:
After the update to 5.1.1. the sony music app and google play music can't detect any songs on sd card. This is driving me crazy! I have been trying to find a solution, searched the internett, tried sonys website, nothing. Can't find anything helpful. However I can play music with ES Music player. But it's not any good music player that one. Anyone of you have the same bug? Or any solution?

Hi

On display brightness problem. I do not have that problem. Using Slim 2.3 Wajk .

But I have observed this in 5083:

I have a delay of 1,5 or 3 minutes when I switch to LTE. This delay is always, with change make quick adjustments and with change settings, more, mobile networks, LTE (preferred) / WCDMA / GSM.

The only way to change quickly is selected in phone menu (* # * # 4636 # * # *) lte only. But it is not solution for me, I like lte (preferred) / WCDMA / GSM

I have correct APN, in 5.0.2 change was immediate. Also all my rom installations are completely clean. And when phone connect lte all runs fine.

You have seen this problem?

Use PC Companion to backup data, you'll need only reinstall apps and then restore data

Weird, I haven't faced this problem since CE1 5.1.1, only got few times on Nordic one. But faced more times on CE1 5.0.2.
[Xperia Z3 Compact General] nielsbrakel1998:
Just updated to 5.1.1 but have a little question, when i unlock my phone there is a ! On the wifi icon but wifi works fine. What does this mean? I have stamina mode on think it is something with that.
[Xperia Z3 Compact General] PuffDaddy_d:
You are correct - that "!" shows up whenever Wifi is reconnecting to the network after exiting from the wifi sleep state.
[Xperia Z3 Compact General] Super2020:
Does it "optimize" for all apps ? Or only few ?

Yesterday, I rebooted my phone while optimizing (I was at 225 out of 250) and upon next reboot, I had only 25 to "optimize".

Not sure what to do with this since no root / flash happen before to this phone.

Anyone knows a direct link to sony support for report ?
[Xperia Z3 Compact General] ajgftw:
I'm no expert, but could it be deleting the cache when the phone powers off as a security measure? Just thinking out loud :)
[Xperia Z3 Compact General] jolindbe:
My feeling is that it got a lot worse, but I am not sure how to measure it. I've just gone on a trip, so I cannot compare with what I typically have at the end of the day, since my usage habits and proximity to cell towers and wifi of course is different than on average days. But I feel that the phone gets hot also when screen is off, and that is unusual.

Is it possible to downgrade without rooting?
[Xperia Z3 Compact General] Super2020:
I don't know, but it was not the case previously (with 4.4.4 or 5.0.2) :x

Not sure what it does, at the beginning it was 224 applications, now it switched to 334... takes about 5 minutes.

Not sure but I would say it began when it asked to transfer things on the microSD due to low storage on internal memory. Unfortunately I accepted and did not remark that part of the transfer involved transferring all apps to microSD...
[Xperia Z3 Compact General] chipchop4:
Honestly it's a big let-down. In fairness the 5.1.1 update was supposed to fix bugs from the 5.0.2 release but come on. A few icon updates, the placebo camera update that I'm sure didn't make any difference and the drop down menu for wireless and bluetooth(who even uses bluetooth)

With this software I can only recommend unlocking the bootloader, and getting cyanogenmod. In the win/loss ratio you can only gain.
[Xperia Z3 Compact General] PuffDaddy_d:
Probably anyone who drives a car that was built in the last 10 years? Just a guess ;)

As much as I like the new cleaner user interface, i'm not sure it makes up for the bugs:

- Auto brightness

- Alarm Clock auto-snooze (U.S. Variant)

- No LTE on T-mobile U.S.

- Google Services and/or Google Music causing stupid high battery drain

I'm trying to give it a chance, but I may revert back to KitKat until xda finds ways to work around this problems.
[Xperia Z3 Compact General] Nplus1:
Well first of all I can say that the proximity to cell towers and things like that are just excuses we try to find for bad battery performance on Lollipop ROMs.

I've clearly seen it at work were I have at most one bar of signal strength (4G). On 4.4.4 I never noticed an issue (maybe 5% drain in idle). I did the mistake of updating to 5.0.2 when it became available and the idle battery drain jumped to about 20% (same location, same signal quality). It didn't get better at all despite resetting the phone to factory setting (another lie we tell ourselves - "it must be because I didn't reset it after the update...") and after 2 weeks of frustration I downgraded to 4.4.4. And guess what? No more battery problems! Same location, same signal quality, same great idle performance (5% max drain in idle during the 8-9h or 10-15% with light usage).

And to answer your question, YES, you can downgrade with Flashtool. It works for unrooted phones with locked bootloaders (like mine) but when you downgrade you have to enable data wipe or it will go into a bootloop.

When you're referring to Google Services battery drain, is there anything related to the persisting mobile radio drain, present all on Lollipop ROMs for all manufacturers? This is the 3rd most starred issue in Android history, still not acknowledged by Google so I'm pretty surprised no Z3C user ran into it on 5.1.1. :D

https://code.google.com/p/android/issues/detail?id=165558

Last weekend I got 2 days and 10h of battery life and about 7,5h of screen on time: 4.4.4 with "medium" usage (only browsing, no games, no navigation, but GPS on all the time, some 6-7 accounts synced, 25% on 4G and 75% on WiFi). I wonder if 5.1.1 gets close to this.
[Xperia Z3 Compact General] PuffDaddy_d:
Yes, that's exactly it. I noticed Google Play Services was causing the most drain on day one, but since I'm rooted, I installed Amplify and it fixed the problem immediately; however, now Google Play Music keeps the mobile radio active until I force close it from the app manager. Simply exiting the google music app won't trigger mobile radio service to stop. It's killing my battery and preventing stamina mode from activating.

I wish there was a way to solve it.
[Xperia Z3 Compact General] RaXelliX:
The radio drain bug was fixed by most manufacturers separately from google. Sony had this fix included in 5.0.2 already. Hence why no one has ran into it on Z3C. Actually the Play Services SystemUpdateService drain bug is much-much worse and this is directly Google-s department that manufacturers cannot fix because Play Services is updated trough Play Store on a constant basis. And this is nothing to do with android version or device as i had this bug on an older Sony Ericsson device running CM11 based 4.4.4 too.
[Xperia Z3 Compact General] Nplus1:
No, it did not. On 5.0.2 I constantly had Chrome for example (and other apps) keeping the phone radio active for 4-5-6h even though I was actually using it for 5-10 min. I'm absolutely sure Sony did not touch this issue on 5.0.2 seeing the number of comments on Reddit, Xperiablog and Sony's support forum.

If you check that issue tracker I posted, you'll see A TON of people reporting this same issue throughout 5.0.2 and 5.1.1 on all kind of devices from Nexus 4, LG G3 and Xperia Z2 to Nexus 6, Z3+ and Galaxy S6.

Interestingly enough, I have no battery drain on the latest version of Play Services, but that might act differently on different OS versions. If that's the only issue, it should fix itself in a few days/weeks after an update, but I'm not that optimistic.
[Xperia Z3 Compact General] RaXelliX:
Looks we are the opposite - you have the radio drain bug but no systemupdateservice drain bug. For me the opposite has always been true.

If something was wrong with the update it would be broken for everyone. obviously something is wrong with your (and apparently 40 other's) setup.
[Xperia Z3 Compact General] Nplus1:
Oh, I just remembered one temporary fix that used to work for me on 5.0.2 with these kinds of problems: force close and clear data for Play Services, with a reboot eventually. You guys can give it a try and see if it works for you too.

tomzzi you could also try to disable Stamina Mode. Some people noticed on 5.0.2 that there was a conflict between the OS and Stamina. And anyway, if you keep things under control (app settings to prevent unnecessary wakelocks) you don't actually need Stamina mode.

So you're saying that ipv6 works for you? Or have you just been set to ipv4 all along? I don't use t-mobile. This bug did not effect me. And a bug doesn't have to effect 100% of users to classify as a bug.
[Xperia Z3 Compact General] acme64:
it is set to ipv6 (i guess its the default?) works fine. Im in the DC area if it makes a difference.
[Xperia Z3 Compact General] bubimir13:
I guess the phone picks up setings from carriers so for that ''bug'' only T-Mo is to blame then as guys on other carriers do not have these issues.
[Xperia Z3 Compact General] ray_J13:
maybe you should let try it for 2 weeks on 5.1.1, initially my z3c battery life was not as good as 5.0.2 and similarly with android OS top the chart of battery consumption

now the battery consumption are similar with the predecessor OS

to me battery consumption in idle

5.1.1=5.0.2 better than 4.4.4

battery consumption when active

5.1.1=5.0.2 worse than 4.4.4

most active app is whatsapp...not sure if it is because of the new whatsapp is causing more battery drain for LLP
[Xperia Z3 Compact General] -Giro-:
With 5.1.1 it doesn't show battery charging (remain XX minutes) on lock screen :(
[Xperia Z3 Compact General] Whitefoxy:
Yea i noticed too :( i hope it get fixed in the 570 firmware update .

[Xperia Z3 Compact General] PuffDaddy_d:
The IPV4 protocol is old. The internet is moving toward IPV6. The standard internet settings from the carrier will include both protocols. If the firmware doesn't work with the new standard, then that's a bug within the firmware, not the ISP.
[Xperia Z3 Compact General] novahob:
Updated from 4.4.4 and have found it over the last couple of days to be good. Small bug/functionality:

1 - not liking the new battery history details as due to it showing how long your phone will last (which is good), to view the awake, GPS, screen on, WiFi is now not readable as it's far too small. Would like something like in KitKat.

2 - I think this is a bug that my contact card on the device, the picture I've assigned to it doesn't show in the stock messaging app. I've installed google messenger to check and this app shows my picture correctly. I also cleared data on messaging app and deleted all messages, then tested but still a blank picture. Anyone else get this or have knowledge on how to fix?
[Xperia Z3 Compact General] corckie:
+ speed, multitasking

- battery drain

- heating

- brightness bug

if 5.0 was worse than 4.4.4 and 5.1 is worse than 5.0, then you have it... 4.4.4 > 5.0 > 5.1. Seriously Sony, great job. I was so happy with Kitkat on this phone
[Xperia Z3 Compact General] Super2020:
So... I gave up after a bad low battery story. I used the PC companion stuff to back up everything and then I did a factory reset. It didn't take too much time to restore (you have to download apps manually tho, but the content of apps is saved).

Having a clean 5.1.1 is much better (and behaves different) than 2 successive OTA upgrades (and it should not be that way).

I'm still guessing it cames from the Encryption issue. It is now MUCH faster to start and I don't need to input the PIN code twice (before I had to do it for the encryption part, then for the login).

Anyway, that was the only way.

Initial observations, it *feels* a lot snappier when you are in app drawer, or desktop icon folders etc, the 5.02 was really laggy, with larger folder of app shortcuts sometimes taking 1-2 secs to show, recent apps is instant, apps too feel brisk & very smooth, it's quite nice actually, sounds like music as well are back to kk levels, or at least the best of any lollipop levels. I'll add to this as I come across stuff, but so far, it's a lot better.
[Xperia Z3 Compact General] techguyone:
Something else, it doesn't do that annoyed the **** out of me with lollipop, sometimes when you went to recent apps, and you'd press the home button it would kill the home screen, and the only way to get it back was to lock/unlock the phone, it's not doing that now.
[Xperia Z3 Compact General] `Ghost`:

Well, for my I had done the update without Reset, then I had problem (most likely due to the fact that my phone was previously encrypted). So I did a factory reset, and reinstalled stuff, it worked.

---------- Post added at 01:43 AM ---------- Previous post was at 01:41 AM ----------

Actually, I'm not quite sure what you call the brightness bug, it does not seem to adjust well (I used to use Lux for that but it blocks too many confirmation pop up, so I went back to the stock one and use it manually). Sorry for the false hope.

---------- Post added at 01:45 AM ---------- Previous post was at 01:43 AM ----------

It confirm it worked. But not for the SD card (where I had only music and movies).

I backed up encrypted phone, Factory reset, Encrypted again, Backed up first (call logs and everything), then re install (manually) my apps and then applied the back up again to re gain my settings and saved information from previous installation.

Hope this helps

Can anyone test https://play.google.com/store/apps/details?id=eu.pyrobytestudio.intelliscreen.full to see if it's working on 5.1.1

For some reason it doesent work for me anymore. It's a program with wich you can set custom screen timeouts in other programs. So for example you can set it so the screen will never turn off if a certain program is running in the foreground.

If it works for you then i can look further to see if there's a conflict with xposed or something...
[Xperia Z3 Compact General] techguyone:
Ok from a 92% charge I have 5 1/2 hrs screen on time, and that's with hammering it, with browsing, gaming, videos, bluetooth, gps & playing music

I reckon on a more 'natural' usage pattern I could get back to 6- 6.5 hrs sot again, I'm happy with that.
[Xperia Z3 Compact General] techguyone:
I just looked back to my KK battery stats, on that I had 6 hrs 51 mins, looks like KK is still going to trump Lollipop which lets face it, has been a bit of a disaster for Google, lets hope Android M is better. I draw some consolation that 5.1.1 has at least been better than the other Sony Lollipop builds.

re: sony kitkat's turn wifi scanning off when no known networks are around.

this feature disappeared in 5.0.1 . I found an official statement that it was removed by sony because v5 has improved wifi battery allocation which made the feature redundant. But battery overall felt worse. I always have that lingering thought in my mind that the wifi scan keeps the phone awake even thou i'm in a place where i can see wifi networks but I'm not connected to any.

Now I'm in 5.1.1 and in a hotel. I'm not connected to their wifi network but as per the battery graph; my wifi was on since i unplugged it. whenever I open the quick settings notifications I see the message "wifi scanning..". Now I think I should turn off my wifi manually when I'm not in areas I don't have wifi connection to. This is a hassle and it makes me miss kitkat where in the auto wifi switch works like a charm. lolippop's project volta isn't enough to match or even exceed kitkat's battery stats for my device. I will do a factory reset in the next few days as I haven't done that since upgrading to v5 and now to 5.1

Anyone else feels the same way I do about this?
[Xperia Z3 Compact General] `Ghost`:
Its only been one day but I feel like battery life has been about the same as 5.0.2. However 5.1.1 does feel snappier and the camera focusing has been very much improved! Images are a little bit clearer and it focuses much faster.
