Network Issues after upgrading to 23.4.A.0.546 - Xperia Z2 Q&A, Help & Troubleshooting

Just as the title says. After updating to 5.1.1 I noticed that I'm getting a terrible network signal anywhere I go unless I'm directly outside.
I could be inside a building near a window and my network will be 1 bar or even less sometimes.
Is there anyone else experiencing this? Is there any way to fix this?
I flashed the Greece version and then updated with my local baseband and kernel etc.
Thanks.

I too have realized there are network issues and my phone is completely stock. No root at all or any mods whatsoever. From time to time I wont be able to load facebook or other social media so I have to toggle airplane mode to have the network reset which gets annoying. Also, my messaging takes quite long to get sent and sometimes the recipient gets the same message 2 - 3 times. I am trying to downgrade back to 5.0.1 but I have no idea how to do that. Most of the posts I googled, go back to kitkat which I dont want.
I hope someone could point me to the right post for the steps. Thanks!

I also have this problem in 5.0.2

Whatsapp sometimes not working over wifi

So sometimes when I'm connected trough wifi my whatsapp won't send or receive messages. I then have to turn off my wifi , receive/send all messages and turn on wifi before it will work again. Does anyone have an idea?..

WHAT firmware and what version of whatsapp are you using?
Is your wifi kicking out a good signal?

I have the exact same thing, no matter what Rom, firmware, kernel, version of Whatsapp, router, modem, whatsoever. It sometimes just happens, no idea why.
When this happens I have a good signal. I'm on 2.3.6, and have the latest whatsapp version.

What did the Whatsapp developers say when you contacted them?
yeah these issues still exist... got it now on my device.
got I9100 on latest cm10 nightly (8th Sept.) with latest whatsapp version. and if you read all comments on the market you'll see that many ppl got these problems. sad
same issue here with i9300 stock ics
it works only on mobile data and when i turn the wifi on Whatsapp doesn't work
tired of deleting and reinstalling but same issue !!!
BTW my device is not rooted ..
i have been using what's app for good 4-5 months now and today i just got this issue. whats app won't work on wifi unless i turn it off and turn 4g on. i tried uninstalling and deleting the folder and did a clean install. it still won't work.
Just hit me last night
Got the same prob since last night!!!
tired to uninstall and reinstall it + boot my device million times and still won't work over wifi but my damn slow edge network!!
i have sent a email to whatsapp costumer's service and still waiting for their reply
These are issues related to the whatsapp Servers or sth. For me it works again. Without reinstall and so on. Just wait ... and tell them bout the problems
I've had this same problem for at least 6 months... doesn't work on WiFi but is fine on data...
What seems to happen is when you turn on WiFi it works fine for a while... but then stops getting or sending messages completely... just sometimes randomly it may start working again... say if you have lots of messages backed up to receive... at times it may start working again... but that means asking you people to bombard you with messages and still its not a sure shot solution...
Quite annoying I must say... especially considering reception is really bad in lots of areas and WiFi is the only way...
WIFI Whatsapp
Sort of same problem here, when i am on wifi and whatsapp and my phone is on there is no problem receive and send.
But when the phone is on standby after 10 to 15 min no more messages receiving, wifi is on.
when i turn the phone on and open whatsapp the messages pop in....
On data without wifi no problem.
WIFI setting always on.
Same problem buy not consistent. I have found a kind of fix, if your rom supports it, I use the long press back to force close function, then restart usually solves it. Alternately, pressing home, then swiping it off the task switcher sometimes helps too. Sometimes all you have to do is wait it out.
Was this problem solved in any of the updates. It appears as though I'm having this problem on one of my phones. It's the stock ROM with great wifi signal.
EDIT: I realize this is the S2 forum and my problem is an the optimus, but I am inclined to believe this is a whatsapp problem

The same problem started happening in the past couple of days. I a using CM 9.1. I enabled the Kill Application on long press of back button and you're right--After I did that and launched WhatsApp, the waiting messages (with the clock icon) went through and I got a check mark, then two.
Weird. All the other apps are working fine with Wi-Fi.
Same problem on my HTC sensation

I travel a lot and i was in India Last week and this week i am back in germany and it suddenly stopped working on saturday.
Any Solutions would be really appreciated.
Try this! Worked for me !!
I used VPN which worked for me . But i wanted a permanent solution. So I upgraded the modem firmware. Now it is working fine
Sorry to post here, but Im facing the same problem on my galaxy s5. I've tried a lot of things and nothing seems to fix it. I've changed my wifi router and the problem persists.
anyone came with a solution?
The problem is on the wifi router. I changue my router two days ago and i hadnt no problem with the old one.
If you retry to download pictures, it gonna works, but its really slow. Try to changue your wifi router to a newone
***********SOLUTION*****************
Guys,
I have also faced the same problem and here is the solution:
There is a Problem which started on 10th November. BSNL has blocked whatsapp.. BSNL users can not use whatsapp through wifi or dongle.
But there is a solution for this.. :
Install " vpn one click" or "Easy Surf VPN" app
Connect to India server
Or any country
Once ur done with this, u can use whatsapp and all the other sites blocked by BSNL
Enjoy Whatsapping

[Q] OMNI ROM troubles

Alright.... I dont have enough posts to put this in the development thread. I took the omni rom ota update and like a few people my phone rebooted to the invalid software please take this phone to a verizon store..... I odined back to stock and eventually got things back to normal or so I thought. Now it seems that anytime I am on an aosp based rom my signal is borked. When I am on a touchwiz rom everything seems fine. It does seem to want to go to global under mobile networks and my singal strength seems way lower than normal also the connection seems much slower. So i odined back to stock again and backed up the apns went back to liquid and restored apns. That didn't work. I can receive and make calls no problem. I can receive sms and mms. If i go into mobile settings and change it from global to LTE then turn on and airplane mode it will send messages for maybe a minute then it cuts back out. I am assuming my next step is to get a new sim card. If anyone has any ideas I would appreciate some input. I have been searching this and other sites since the 24th when I took the ota and have had no luck. I have been on this site and fiddling with my androids since the original droid. I didn't think I was a total noob but this has me stumped.
I am on MDK and my IMEI seems fine I actually Just noticed my IMEISV says "00". So help please!
You're having problems with SMS?
Try going from TW to the GPE rom and see if if keeps working on that, then if it does go from that to whatever rom you want.

[Q] problem toggling wifi

Hey guys, I've had this problem ever since android 4.3, had it on 4.4.2, and after trying liquidsmooth's 4.4.4, the problem still exists. Wifi keeps dropping to LTE, and if I try to toggle wifi back on, the toggle switch "hangs" for a moment on the "on" switch while greyed out, and then automatically switches back to the "off" switch. Only after some time passes, sometimes taking several days, does the wifi randomly switch back on. Does anybody else have had to deal with this problem? And how were you able to resolve it? Thanks in advance

Hmm sounds like a Rom problem. Does anyone else installing Liquid Smooth have that issue? You should post in the Rom's thread and ask..If so you know your answer..
Another thing you can try is swapping some system files.. Post back here if no one else has the issue..

Thanks guys I went back to 4.1.2 and reflashed my way up through 4.3 to 4.4.2 to cm11. Hopefully this will clear up my Wi-Fi issue, will report back if the toggling issue persists

*never mind, wifi dropped within an hour of installing cm11 4.4.4. Any suggestions would be much appreciated.
- to Acez71: I flashed MJ9 firmware, still no go
- to lacoursiere18: The problem still exists on CM11, I'm beginning to think the problem isn't ROM specific
Update: it seems my issue was hardware related, specifically the two gold contacts inside the cover and the two points on the back of the phone weren't making good contact. After cleaning the points and securing the cover firmly my WiFi issues seem to have disappeared for now. So if any of you are having similar issues, make sure to check the WiFi antenna contacts on the back of the phone

No MMS

I have the same issue. Can't send or receive MMS. Everything else is working great!
end button not working
I love this rom Wilson made! It is super fast and works great. I am having just 1 problem with the ROM. When I end a call the call hangs and doesn't hang up. I can still hear the call in the background but all my buttons grey out. Is there a fix to this? Also I noticed I'm not receiving some calls. I do receive some calla but not all. Anyone knows the fix?
Data not working
Interestingly enough, mobile data worked for me all day yesterday, but stopped working sometime overnight.
Flipping airplane mode doesn't fix it, but changing the preferred network type to CDMA w/o EVDO, and then back to CDMA+LTE/EVDO brings it back, (the same type of fix for previous AOSP ROMs' SMS issues.)
Has no one had a problem with data connection? I flashed 5.1 and it worked great for awhile. then I started getting the exclamation mark next to my data signal and my Pandora would not stream anymore but would work over wifi. Sometimes messing with airplane more and re-saving the APNs worked but most of the time it didn't.
I flashed 5.1.1 and it worked at first. then it started doing the same thing. Something strange I noticed is that i did still have a data connection. I could perform speed tests and connect to my multimedia server, but loading websites took forever/didn't work and Pandora loads the artwork, song title and artist etc. but never plays. When I tried to input APN settings manually, after saving them the entry would just disappear from the list. Even modifying one of the pre-existing APN options and saving it would make it disappear.
I checked that the phone isn't in battery saver mode. I flashed back to my old rom but would really like to figure out what's wrong since i'd really like Lollipop on my phone.
Edit: Changing my APN type(like the above post suggests) also didn't work.

Same here. Are you on Verizon or something else? Just curious because this issue seems pretty isolated. The reason i ask is because I'm on straight talk.
I have an annoying encryption issue. Before this ROM, my phone was encrypted. I booted into TWRP and did a full wipe/factory reset and installed this ROM. Now I want to re-encrypt my phone and when I go to do it, it says it is already encrypted. I know my phone is not encrypted because I can boot it without a password or have TWRP boot without a password. I'm not sure what to do at this point.
Thanks
This is the 5.1 rom for the i605 note 2
I have been running this rom all weekend and got to say loving it.:victory:
This Rom is running at 100% on my i605.
Any chance App circle bar will be add?
Would like to see it added but not that big of a deal.
Are there any Xposed for this rom?
Still can't believe i'm running 5.1.1 on my i605 and its this good.
THANKS and GREAT JOB GUYS:good::good::
Are there any Xposed ?
I've stayed up to date for the last couple months of releases. I love the ROM and everything seems to work great. I've only encountered two tall deal breakers across all updates. I really really want this ROM to just work.
- Am I only one getting the random "Camera cannot connect" issue?
I say random because I can't identify any particular event causing camera to fail.
- Any fix for Cellular Data randomly quitting?
I know others are having same issue. Has anyone found any fix?
Full wipe and fresh install has brought no success.

Your not the only one having the camera problems. And the data fix is already in the thread (Settings, mobile network, Access point names) try remove all fakes and if your running AT&T or T-Mobile turn off LTE so H,H+ will stay locked in.
Please give thumbs up if this helped anyone

I would make a backup to my External Sd Card and (Swipe to factory Reset) three times if you dirty flashed the first time.
If not in advanced wipe check ( Dalvik cache, Cache,System,Data, and Internal Storage ) all three times.
Remember your backup is always on your Ex-Sd card

Oh I just notice hot spot toggle missing as well. Good to know I'm not alone. Hope to see some solution soon.
yep on carhd custom rom and mine disappeared overnight too?? bizarre?
any fix available please?
thanks
I thought I was the only one
I was about to create a thread about this, especially on my devices it's not only the Mobile Data and Mobile Hotspot missing, but quite a few and it's really annoying, I was thinking that maybe after gaining root and changing the build prop settings for better multitasking caused this or maybe the mod I applied that removed the S-finder and Quick Connect buttons, did any of you guys make this modifications, check my attached screenshothot to see how worse mine is I was even thinking of going back to stock
Also I had a backup on Flashfire and when I restored it, everything was back to normal buy after some few minutes the issue is back again
Holy **** I thought I was going nuts !
Same problem here in Switzerland, Int. version. No update, nothing but during this night the toggle disapeared. I have no idea what's going on.
Same In France
grooted s6 edge not rooted
This is how it was before
I just restored the flashfire backup to see how it was before, check this
So you not rooted and facing the same issue?? If yes then it means that my assumptions we're wrong that it's probably because of the modifications I explained on my first post above

Not rooted, same issue sadly
ive got new button in place...Network restriction? but it cuts out everything data wise..like airplane mode- but you cannot put wifi on afterwards??
mines rooted but not changed anythting at all since rom install. its just removed by itself
Didn't have the time to look much into it but without any software update could it be related to Google Play Service ? I mean, I don't see how they could remotly remove it from us ?
Fix
Same thing here, no data toggle.
I fixed it through sqlite editor. I added MobileData and changed the number of active toggles.
Updated OP to mention I did not root
Wow. Seem like a lot of people having this issue. Interesting. All occur at once. How does this happen.
Should we wait or do a Factory Reset ?
This is a common issue since today. Something happened 6-7 hrs back causing this issue.
The big question is "what's the fix" ?
Since mine is an unlocked non-carrier International version, I am sure this is not a T-Mobile or Verizon issue.
Is there a way to contact someone in Samsung about this problem ?
Will a FACTORY RESET solve the issue ?
Any ideas ?
Has anyone tried a factory reset yet, I'm facing the same problem, some of my toggles are just gone. Not rooted, factory unlocked, so I have no idea what's going on.
