Not receiving push gmail and whatsapp on wifi - Xperia Z1 Q&A, Help & Troubleshooting

I'm experiencing problems with Gmail and whatsapp: whenever I'm on my home wifi the push does not work. But more problematic, sometimes it does work. Next to that when I go into whatsapp after a day of no messages they all arrive at once.
So I'm able to receive messages and Internet works, but the push services doesn't work most of the time! I'm not on stamina mode or any other battery app (BTW battery of my z1 is worse than my sp).
Does anyone have an idea how to find out if there's a culprit or what settings I've messed up?

So nobody has a clue I gather?

To my look like the Auto-Sync is OFF so turn it ON. If is already ON probably Gmail and Whazzuppe is not in the list so you have to addict it manually + Add Account.

Thanks for thinking with me, though that is not the case! Sync is on and it works perfectly on other wifi networks.
I can report a more peculiar fact: pinging google.com with Fing results in 100% packet loss, though pinging for example tweakers.net gives me an average of 40msec. Strangely I can brows to www.google.com in Chrome... It seems as though there's something very wrong with my Z1 because pinging Google.com with my Xperia SP does work!

Any news on this?
I'm experiencing the exact same problem. It has been around for at least a couple of months on my Nexus 4.
Most of the times I don't receive any push notifications. I need to open the app manually, wait a couple of seconds, and then all the new messages come in.
Here is what I tried so far:
- Notification settings for each app
- Reinstalled complete OS
- Background data is allowed
- Wifi policy is "Keep Wi-Fi on during sleep" -> Always
- I don't have any battery savings or task killer apps
http://forum.xda-developers.com/showthread.php?t=2599417
I also tried this, and now I only have the OS and Whatsapp installed. But the problem persists.

I have the same problems since KitKat.
Sometimes I have to open the app to become the messages.
I had this problem with 681, then I done a full wipe and installed the 757 rom.
But i also have this problem....

So as it turns out, the problem only exists in my wifi at home.
When I'm at the university everything works fine.
I also noticed that facebook and instagram are very slow on my phone at home.
And only the apps, not the websites.
(this also has been around for a couple of months)

Having the same issue with my HTC M8. Guess I just have to find out what settings are causing this on my router.
Edit: Fixed it. My VPN's DNS servers were blocking push. Changing them back to googles DNS brought push back.

Actually, I was also facing the problem. I tried to get it solved by uninstalling all the recently downloaded apps, but it didn't work for me. And I couldn't uninstall all the apps.
Then I got the idea that it may be because of some setting on my router. I don't know much about router settings. So, I finally installed the VPN App Opera Max and it worked. It was a big relief for me.

Max does not change DNS settings so in theory it shouldn't fix this issue. It's possible that your issue was unrelated to this one.

[Q] Forcing Whatsapp to stay connected ?

Hi,
I have a problem with Whatsapp program. It works perfectly fine when it comes to sending messages, although I have a problem with staying connected. The messages are delayed (sometimes it's even over 30 minutes) and when I simply wanna unlock my phone and text someone, the person won't receive my message until I reconnect my mobile data (grey clock icon on the left of my message). I've already seen many instructions on the net, like reinstalling Whatsapp, rebooting my phone, checking if my sync works and all that, but none of them worked for me. It really starts to annoy me, but I like this program alot and I don't want to give up on it that fast. So is there any way to force Whatsapp to stay connected full-time ?
I'm using MiniCM-2.2.0 with latest nAa Kernel.
Regards
Bump, spent the whole night browsing the net for similliar topics and found nothing...

well maybe you shouldn't give up on whatsapp but the ROM instead. What i mean is, maybe something inside the ROM/kernel wasn't installed properly and you could try reinstalling ROM and/or kernel... I know it's a stupid solution but it saved me many times when i couldn't find the answer anymore

Thank you for your reply. I already had the problem on previous ROMs (I mainly used MiniCM). Maybe I'll give GingerDX a shot. I'll tell you how it went.

Did you leave the app in background? When you leave Whatsapp, dont click back button, try clicking home button?? Dont move app to SD if you did!

i belive that whatsapp is running in background by default, so as programs such as viber, hotmail, etc. but we all know that this can be checked under settings > applications > running applications
but i agree that moving whatsapp to SD could be the problem, although i had no problem when i moved it to SD
I didn't move it to SD card and I don't use any task killer. Process manager says it is running in the background. Still no idea how to fix it.
if it isn't because of moving to SD, and it is running in background, if it isn't because of ROM (you've said that you have used some ROMs before and that there was the same problem), if your data settings work normally (sync and stuff), if the problem persist on wifi and 3g and edge,...
it occurs to me that it can only be due to two things, maybe you installed cracked version of whatsapp due to 1-year-free expiration, or maybe something went wrong when you installed your current kernel
P.S. whatsapp is 70% of communication on my X8, and i understand you very well when you say that you won't give up on it so easily

I didn't crack anything, I'm still on trial. If I wanted to get another free year, I'd change my phone number I also reinstalled the kernel too.
EDIT: Now it works properly on WIFI only. Still disconnects after couple of minutes on 3G.
EDIT2: It seems like reinstalling GDX and Alfs finally worked for me. Thanks for all the help guys
Another update:
after a few hours I'm back to the point where I started... the problem's still there. I'm really pissed off now -.-

It is only logical that Whatsapp won't implement itself right on your phone... This is all ridicoulos right know, because for as far as i know, you almost tried every solution possible, you've changed to other ROM, heck, you've even changed to other kernel and it still doesn't work.
You said it worked for a while, maybe some of the settings you've changed, and apps you've installed AFTER it was all working properly was interfering with your newly applied settings and/or installed apps

I've installed Advanced Task Killer to see if it's the problem with Whatsapp, but it didn't block me from receiving the messages or anything. I uninstalled ATK and like an hour later, the problem occured again. I'll reinstall the kernel and the ROM again and leave it with only Whatsapp installed for a day. If that doesn't work, I might just buy an Xperia Neo V :S
Maybe it's because I connect to another network instead of my providers one ? I have data roaming enabled and stuff and I connect to Plus instead of Play (even though Play says they allow such things). Could this cause the problem ?
Or Swype Beta maybe ? I'm running out of ideas...
I just found out that when Whatsapp's not showing the "last seen" date (not connected), when I enter any website in the browser and return to Whatsapp, it shows the "last seen" properly. But I still have no idea what can this be...

Wait, does it work normally when you are on wi-fi? try to test whatsapp when you are strictly on wifi (wich means that you turn off celluar data, data roaming and national roaming), so that we can definitly exclude the problem of wifi.
if the problem isn't in wifi, try to connect on your providers network (PLAY) instead of other network (PLUS), and see if the problem persists
if the probelm still persists i belive there is counterinterfering with some application...
i know that i'm offering too much possible solutions, but i think that this can only be solved by method of trying out every possibility

As from what I see for the last 30 minutes, it's working fine on WIFI. I also tried switching to Play and disabling the roamings, but it still kept disconnecting.
The apps I have installed:
- Barcode Scanner
- Battle.net Mobile Authenticator
- Dolphin Browser
- exDialer & exContacts
- GG (Polish messenger, but I doubt it causes any errors as I just installed it recently)
- GO SMS Pro
- Real Player
- Root Uninstaller Pro (I only uninstalled DSP Manager)
- Whatsapp obviously
- ColorNote
- Nexus ICS Minimal Analog Clock
That's pretty much everything I have. I didn't change anything in the settings of GingerDX itself. I'm really helpless here...
huh, nothing from that list shouldn't interfere with anything... maybe you should put back ATK and see what exactly happens with whatsapp when it disconnects from network
i'm really running out of ideas
It's pretty simple. It's got nothing to do with your ROM, kernel, 3G or WiFi - AFAIK. Rather, I think it's to some extent do to your connectivity. The app's refresh interval apparently varies. Seems worse when you have many long threads. Deleting a few threads seems to work from time to time. I however use another android device & I assure you the problem is in no way restricted to the X8

So it's normal that I get my messages delayed by around 30 minutes or even more ? I clear my logs every day, so I think the messages should arrive like... instantly :S

Hi,
Do you still have the problem of the messages getting delayed?
I have the same problem since three months now I think.
I have already tried everything you guys said here.
I have no problems what so ever on WI-FI but only on 3G.
I think it has something to do with Whatsapp, maybe even with our accounts in specific.
Did you ever fix this problem?
Because I am having it on my Samsung Nexus S.
I found that when I send a message, and I am running whatsapp in the background I still woulnd't recieve the messages.
So I hope you found the solution and could maybe share? :angel:

Youtube and google play store issues on wifi

Many times I open google play and it says no connection retry, I just keep hitting retry and it usually works. On youtube however the same issue arises and I press retry and it does nothing, it says there's still no connection. I believe this is a wifi issue as I switched on my 4g and the video loaded just fine. Also sometimes on my PC I get some error that google doesn't have a valid certificate so I don't know if that's part of the problem as well. How can I fix it? Are there some router settings I should change?
Exact same problem here. For me it happens on wifi and normal data. .

push
I have the same issue and cant find a solution or at least the reason for it
I had the same problem and I think upon reading something in here, I deactivated the Autosync feature and couldn't replicate the problem. However, that was the source of another problem detected afterwards, as it would not push notifications to weather/mail/Blinkfeed. I would've thought having AutoSync on syncs everything under accounts by the default settings and having it off, you could manually set the sync for accounts separately and they would still work, but I haven't been able to set things up so as to avoid both issues. It's probably fixable by these means, though.

Whatsapp connection issues

Hi, I wonder if anybody can help me. Up until the day before yesterday I was using whatsapp fine over wifi (where I am at the moment there is no mobile signal) on my O2 UK Z1 and then whatsapp lost all connection. Everything else on the phone was working fine but no whatsapp. Every message I sent would go to the clock, no information when people were last online and the faq etc. in the settings would not load because of lack of connection.
I uninstalled the app and then installed it again and all was fine, after sending a few messages the same error occurred again. I have now found that if I clear data in the app settings it will connect again, once I have reconfigured the app and restored from backup. I can only assume that there is some sort of buffer which I am clearing as I lose a few messages when I clear data (all since last backup).
Barring doing a delete of all backups and messages does anyone have any other idea. I have looked and the backup files are about 1.7mb so not massive and I have a fair bit of storage available onboard (>7gb).
I was talking to someone with a HTC phone who had suffered similar symptoms but I have googled and searched and can't find a solution.
Any help much appreciated.
Mark
2 weeks off work and no issues, as soon as I have returned the issue has reared it's head so looks like it's something to do with the wifi here. Everything else works fine and fast so I guess I'll just have to live with it

Try to factory reset or reinstall mobile data settings

A factory reset for a cheap Whazz, huge work buddy...lol... at last it's an idea but I will try reinstall mobile settings before that or uninstall and reinstall Whatsup.
I work in a very remote location, I have wifi (which is distributed from a satellite feed) out here and for my mobile phone that is the only connection option. When I am away from work whatsapp always works, both over wifi and cellular data. At work I keep my phone in aeroplane mode with wifi turned on to try and preserve some battery (there is no point in my phone constantly looking for a non existent cellular signal).
This morning I deleted all messages in whatsapp, uninstalled the app and re-installed/configured. Usually I get a failure within 24 hours of doing this so we'll see whether this rectifies the issue.
I know I'm not the only person out here that has had the issue so it is either a coincidence or something with the way the wifi is configured here. I just assumed that the wifi would either work or not but, I am not an expert.

[Q] Problem with wifi after lollipop update on Sprint HK M8

Hello,
My wife and I are both having similar issues with wifi after updating our phones to lillipop. We can connect to the wifi, but apps that require a login or apps that have an optional login are giving errors saying that there is no network (Network issues, no connection, etc.)
Apps that don't work with wifi: Bank apps, Amazon apps, Twitch, Feedly, Speedtest.net, etc.
Apps that do work on wifi: Chrome, YouTube, Drive, Mail apps, etc.
If we turn off the wifi, everything works fine. We both are running stock phones, I've got the HK M8, and she's got an older M7. There are times when a few of the apps will work for a few minutes, but then the issues come back. My wife's phone is also able to connect to our work wifi, when there, some of the apps that don't work at home will consistently work, but not all of them
We've both been told by HTC to do factory resets and to flash the latest stock RUU. The issue remains even after doing this. I don't really want to do the next step of sending in our phones for 7 to 10 days while they "repair" them.
I've tried everything I can think of. I've also factory reset our router and tried every wifi channel and/or security option, hoping that it is an issue with my wifi router.
Does anyone have any idea of what I can try before having to mail HTC my phone?
Thanks for any help.
Sounds exactly like the problem I had. Factory reseting the router took care of it for me though...

Hey there, i have been using an M8 for two months now and the problem that I have, which fits exactly the description of yours, is starting to annoying me. Every time I try to use these apps which need login I have to turn to mobile data to be able to do it. In my case, the issue that us affecting me the most, is with whatsapp, which even though I do can use, I cannot download media on wifi! (Neither pictures nor voice recordings).
It's a real pain in the neck to be doing this all the time, and I have two friends who also have m8s and are suffering from the same problems, so I guess it's something quite generic. Besides all the other android phones in my family work just fine with my router, so the problem is clearly mine. I think that HTC should have done something about it long time ago if it is such a common issue, considering that the price of the device is not cheap...
Anyway, my question is: have you been able to solve the problem? If you have, would you please take a min to share the solution? I would be deeply grateful!
Cheers and thanks in advance
I am using my HTC One M8 HK with lollipop update from the time they released and never had any problem with wifi. I use wifi wherever I go and no problem with anything. Try the following solutions:
1. Check the WiFi Router. Most of the times it is the problem with your router. Check if there is any restrictions or whitelist/blacklist of services.
2. You might be having some apps with whitelist/backlist running in the background. It could be your antivirus app, battery booster or Opera app, etc which does the wifi whitelist.
3. If you are using the sign-in wifi networks, make sure you signed in to the network using the browser window before opening the app.
4. If you are using the VPN (even in the wifi network) you won't be able to open the apps like Bank apps.
5. If the apps you installed are not supported in your country, you won't be able to access.
Try uninstalling and reinstalling the apps. Sometimes, when you upgrade to different OS partitions are not aligned properly. Reinstall and check.
Good luck

No notifications while using mobile internet.

I bought a pixel 5 to do courier work, I just needed something reliable with good battery life to run GPS and a handful of delivery apps.
Since the day I bought it I have had problems with notifications on mobile internet, for the most part I don't get any for any apps until I connect to wifi, then they all come flooding through at once.
I have tried every fix ive come across, changing from 5g to 3g, installing a heartbeat fixer app, changing background battery and data settings. Sometimes they seem to work, sometimes restarting the phone works but nothing sticks. I have spent hours talking to google support, they have made me factory reset 3 times, it normally fixes it at first, but last time it didn't and even with a completely fresh OS I wasn't getting any notifications on mobile internet, I tested by emailing my gmail account before installing any more than the default apps.
I should note that I have a strong internet connection the entire time, If i open gmail and refresh it the emails are there, I just don't get notifications for them until I connect to wifi.
The lack of notifications breaks a lot of apps as it seems they rely on the notifications or whatever protocol they use to work. The big issue for me is one of the courier app will give me no runs unless notifications are working.
Anyone have any ideas? I'll happily paypal anyone who can suggest a permanent fix $50 lol, if not I'll have to buy a different phone.

Sounds like you have a lemon on your hands.
I don't suppose you're using a VPN? I've had all sorts of strange issues with notifications and using a VPN as when the phone goes to sleep it can disconnect you from the network.
Or apps like Netguard where you can set apps to connect to either the wifi or mobile network or restrict them.
If you have no apps installed that can restrict your network usage then it seems your phone might have a problem.
No, even straight after a factory wipe, no notifications, that seemed to coincide with the latest pixel update a few days ago because nothing I tried would get it to work which is why I factory reset and for the first time it wasnt working after the factory reset either.

I don't suppose it's something simple as...
I sent myself some emails and used the "find my device" in order to cause some notifications, as you can see on the video, nothing comes through until I connect to wifi.

Yep I think it's time for a new phone lol.
Have you tried a different provider, a friends sim card? It may be incompatible with the P5. There was a problem in USA with Mintmobile and the P5 but Google fixed it. Which service provider do you use?
