Data lag - Xperia Z2 Q&A, Help & Troubleshooting

Often when waking the device from screen off, I get wifi data lag. As in it takes about 10-20 seconds before any apps will load any downloaded data. During this time the wifi icon shows uploading and downloading. App elements that I believe are part of the app itself (frame elements, text, icons, etc) are all on screen, but no remote content (which is why I believe it's data lag, as the phone itself is loading apps and such just fine). After that, data downloads just as snappy as it should. I can turn the screen off and back on with no lag. Then if the phone sits idle for a while, it often happens again. Or sometimes does not. Same thing with rebooting. Lag is there sometimes, sometimes it is not. And I know it's not my wifi, because I already tested other devices that download data just fine while my phone is still waiting for data.
Anyone else have this issue?

Do you have queue background data turned on in power management settings? Or maybe you have turned off keep WiFi on during sleep in WiFi advanced settings.

@rappa619 nailed it.
Sounds like wifi queue is enabled in your power settings.

I have queue disabled, wifi optimization disabled, and keep wifi on during sleep. None of that helped.
Not positive, but it may have been my internet (even though two laptops and three ipads in the house were not having this issue). Internet went out completely a few days ago, and since resetting it, the lag seems to be gone.

Incorrectly using 3G when on wifi

Has anyone else noticed their Lumia using 3G when it shouldn't be e.g. at home with a working wifi access point?
Mine has done this a few times and because WP7 is so clean and simple it's pretty hard to see what's actually going on - there's no data counter. And to make it worse the data icon shows in the status bar even when wifi is on. Ideally it would show one or the other.
Yes, I notice that too. It could be a bug.

Yup, I think it uses 3G when the phone is locked, as the phone seems to disconnect from Wi-Fi when you lock the phone. Another bug that probably needs addressing.
Yes! This affects me too.
It switches to 3G randomly when I'm on wifi and kills my data without me realising (or shows failed page loads when I have full wifi reception).
It also turns off wifi whenever I lock phone which seems to disrupt/cancel all push messages! Push messaging just isn't working.
So is this problem unique to Lumia 800?
i've noticed this too. it'll also present me with wifi hotspots to connect to, including ones it should be connected to.
as of now, i don't know whether it's an issue with locked or unlocked handsets. my handset was bought unlocked with no branding, but i've noticed some of the bugs i'm having don't seem to happen on network locked/branded handsets.
It's not a Lumia thing, it's just how WP works. Turning off wifi to save on battery use I guess. Android has the same default setting, although it allows you to change it.
I can understand it using 3G for background processes, like you say Android does the same thing.
What I can't understand is it using 3G when I am using the web browser on the phone, and the Wifi icon is lit at the top of the screen.

That's not the case actually, before the firmware update I used to get my notifications, after the update, I don't, I think Nokia did it on the firmware update.
Which firmware was this working in btw?
Oh and turning off WLAN when you have an active connection does NOT save power. It only saves power when there isn't an active connection because the 3G uses more for retrieving background data (eg. regular email, social networking updates) and *much* more for retrieving heavy data. I have tested this on numerous Nokia phones.
^ i got the opposite result - normally i have WLAN turned on at all times, because it always connects to wifi at home and at work. my battery lasted much longer (it lasted the night with 39% left, as opposed to going flat sometime in the night) with just the 3g turned on.
I noticed that wi-fi only stays on after you lock the screen if the phone is charging. Otherwise it cuts the conncetion. Very annoying indeed if you are downloading big games over wi-fi. However I get my notifications and emails just fine in any case. Remeber though, windows phone doesnt support proper push, hence why they cant get skype to recieve calls in the background. Facebook and whatsapp push always comes about 3-4 minutes later than needed.
Another thing that i have been testing for a while on various phones (nokia n9 included, not the lumia because it's too unreliable) and also got mentioned in this tread is wi-fi vs 3g consumption.
So my results are:
with 3 emails 15-30 mins sync or push for one, at least one push service eg, facebook, vkontakte whatsapp etc (where possible)
i concluded that if you just leave the phone there for a day in standby and dont use it, it drains quicker with wi-fi on. Everytime. Every phone.
However when using the internet eg. browsing for half an hour etc. wi-fi uses a lot less battery than 3g.
So only use the wi fi when you need it and switch it off for background tasks. (WP7 does that anyway, for a reason)

[Q] After JB update, wifi always off in sleep

I like keeping my wifi on while my screen is asleep so that I can receive chat messages or e-mails without being at my computer. I never had this problem while running ICS on an unrooted TF201, but ever since I installed the upgrade to JB my wifi will always disconnect after the screen has been asleep for a few minutes. I've checked every setting I can think of. In the Wifi Advanced menu, I have it set so Wifi is always on, and in the ASUS customized setting I have Disconnect network during sleep to off. Under Power Saver I have Enable low battery settings off, set Low battery level to 0%, and even set Wifi OFF to off. Despite all of this, it seems like the tablet under JB goes into some sort of deep sleep and disconnects the wifi after about 5 minutes of inactivity.
I have noticed that this problem does not occur when the screen is on. I also have the dock, and set the screen to always on during meetings in the event that I don't need to enter any notes for a few minutes so I don't have to fool with any delays from screen wake .
Is there some setting I'm missing? Is it a hidden setting that I could access by rooting? Or am I dealing with something internal to the build that I can't change at all? This may not seem like a huge deal to most, but it has become one of my main uses for the tablet when I'm at home. I'm very disappointed with JB so far even though the wifi does feel more responsive on the Prime after the update (when it's not sleeping, of course!).
EDIT: I noticed this evening that the wifi turns off even when I'm running something that uses it while the screen is off. I was listening to Pandora, and about 5 minutes after the screen went off, my music stopped. When I turned the screen back on, I saw that the wifi had indeed become disconnected.
hey,
I have exactly the same problem with my tablet. I have checked every option, I did a factory reset several time, I have checked it on 2 different routers but it is still disconnecting the wife when it goes in the sleep modus. Did you or anyone else find a solution?

[Q] Samsung Galaxy S3 always at 80% RAM usage / Google Now problems

So, it's been bothering me for a while but my now 2-year-and-2-month old Samsung Galaxy S3 always just runs incredibly slowly. Not only that, but I tend to burn through the battery easily within 6 hours. For the past year and a half, or so, I've had to resort to carrying around two spare batteries with me as it has a tendency to run out of charge in the middle of the day, let alone if I'm out at a music festival or something. I'm not a particulaly heavy user, as in I rarely play video games on my phone, nor do I really watch videos or ever use bluetooth. Occasionally I do use GPS or WiFi, but I try to keep them turned off when I'm not using them. I tend to use my phone for music when I'm in the car, or texting / whatsapp / occasional snapchatting, or checking Pulse News or my internet banking. I don't have a particularly huge amount of apps installed, I don't think. And I regularly hold the Home button, & press the close-all-apps button to make sure that they're not running in the background.
Yet, my phone is so laggy. It's like there's a constant 3 or 5, or even sometimes 10, second delay for whatever action you've initiated to actually occur. You'll press Messages, and it'll take about 4 seconds for my text messages to show up. You'll press Home, and it takes about 3 seconds for it to close. Facebook just took about 8 seconds to load. It doesn't sound alot, but it can be quite infuriating when you're trying to get things done in a hurry. It's even worse when apps are running in the background!
So, I got to check my running processes and there's just loads of things running that both don't appear to be running when I hold the Home button but also shouldn't be running because I haven't used them in forever. It appears my phone has approximately 850MB of RAM, yet my phone tends to ALWAYS run at around 725MB used (currently it's at 751MB, as can be seen in the screenshot attached). But when I do go through the list of things running, the right hand side it tells you how much RAM is supposedly being used. Yet if I total up all of the RAM being used by all of the apps that are apparently running, it only comes to about 300MB. So where the heck is this other 450MB of RAM being used?! THIS is what is slowing down my phone, I think.
Not only that, but there are things in this list that are running that shouldn't be running, & I don't understand why they are. Facebook, sure I can understand, in case you get a notification or something. But TuneIn Radio... I'm not listening to the radio at the moment, nor have I used the app in weeks (and my phone has been restarted numerous times since then), why is it running? S Voice, too? Video Hub? Google Play Music, I've never even used it. And then there's loads of things I haven't got a clue what they are, like Exchange Services, ELM Agent, SmartcardService, etc. Now I understand it's like a computer, where there are a number of background processes that have to run to make the OS work, but why are all these other apps running that I'm not using?!
-------------------------
Furthermore, I've started trying to use Google Now because I would like to get a Moto 360 (but I'll ask questions about that in a seperate thread). So, it seemed to work fine a few weeks ago. It gave me stocks, news updates, ETA to work or home, started remembering where I was parking. But now a few days ago I go back to it, after not using it for a little while, & it's all reset; Asking me to set it up again. So I did, & it mostly works but I can only ever seem to get the first "page" of cards up. When I click "More" at the bottom I just get an endless spinning circle & then the message "No Internet Connection - Content was last updated X minutes ago" appears as the top card, when infact I know I do have an internet connection. Exiting the app, closing it down, & then re-opening does not fix the issue either. I'm at a complete loss as to what to do.
Furthermore, it always asks me to "Improve my location: For more accurate location, let google search for Wi-Fi connections, even when Wi-Fi is off." I don't understand how this works, and what it's trying to do? If I turn it on, is that not going to be effectively the same as leaving my WiFi turned on at all times? Well, except without the benefits of being connected via WiFi. It's just going to drain my battery more, as leaving WiFi on usually does.
-------------------------
So tldr:
- Why is my RAM mysteriously using 450MB that I can't vouch for? Where is it going? How I stop it?
- Why is Google Now not letting my manually update the cards?
You are missing huge amounts of very basic information, search and read for what is safe to disable on stock rom, some things are vital others are optional.
If you leave everything running as default then 6hrs battery life is about right.

[kenzo] MIUI line defect, data connection problem

Hello
Each time when I back from custom rom to MIUI Global Version I have two problems:
1. Line defect on the bottom of screen. It appears randomly, not each time.
2. Usually I have set that data connection turn off after 5 minuts of screen off. Later when screen is on data connection should return. Problem is that often it is not turn on again fast. Sometimes it takes one minute, or I should press data button to activate it.
Both problems are on all type of MIUI (dev, stable, even xiaomi.eu). So I thought it is some problem with hardware, but on custom roms everything is ok. Does anyone have idea what could happen and how to fix it ?
Here's the picure of line defect:
https://www.dropbox.com/s/0kavo3a2f7wzn6g/xiaomi.jpg
That bottom line thing in the status bar has been there for a long time. It appears after a reboot and disappears after some time, so not much of an issue.
But yeah, mobile data seems to be seriously messed up in MIUI now. Sometimes it just doesn't turn on, and I've toggle airplane mode a few times to get it work. Internet browsing speeds that I'm getting are terrible, more so when using WiFi. When downloading some large file or so, the speed picks up and seems to be ok, but browsing is terribly slow. Also, even though 4G signal strength is very good in my area, it sometimes unnecessarily jumps back to 3G in MIUI.
Custom ROMs don't seem to have these problems and data is fine. So, it's not related to firmware I guess.

Recent delay in notifications

my GS9+ is on the verizon network if that matters.
In the last 4-5 weeks my notifications, especially those with sound have become severely delayed. It is especially noticeable with apps such as:
SmartThings (when doors open and close at)
Nine (Exchange email)
HikVision Connect (Doorbell camera motion notifications)
It seems to happen more often when on wifi, but i can't confirm that.
When I get up at work from my desk it is like the phone wakes up and all of the sudden I get 5-10 notifications all at once. This also happens at home. It is like the phone wakes up and catches up with a bunch of notifications that it forgot to report.
SMS notifications don't seem to ever be delayed.
Was there a software update or app update that someone knows that might be causing this problem?
Granted I don't have Verizon at all, but my s9+ isn't having any notification issues.
Did you try disabling battery optimization? I turned mine off so that the phone wouldn't put apps to sleep and etc. Power savings for wifi turned on? If so try making sure that's turned off so your phone stays connected to wifi when the screen is off.
Any of the power savings mode enabled or other power savings apps you may have installed?
Mobile data plan permitting try running the phone on mobile data only (no wifi) to see if the issue happens as well.
Are there other apps effected by the issue your having? If a select number of apps are effected (and others are not) try getting in touch with the app developers and let them know what is going on.

I'm on Verizon. Similar deal. I let a system update get applied "Just security patches, no big deal", and it broke some of my notifications. Not all of them. Just some of them. I thought this was early Sept, but might have been in late Aug.
It's "doze". It used to only happen if your phone sat still for 20 min, but it was supposed to wake up with movement. Now mine kicks on after 3 min and movement doesn't impact it at all. You are supposed to be able to whitelist apps you don't want put to sleep, but it seems to be ignoring that setting for some of my apps. After three min I can send my phone a message, and it won't alert me at all. It's not until I turned on the screen, that they all come rolling through.
