If anyone has gotten restricted access changed i know why

So I unlocked my boot loader and went crazy flashing everything from radios to logos to a ported 4.2.2 (thanks topsnake) and all was good untill a few days ago. All of a sudden i would lose data and call reception my bars would go grey with the circle with a line symbol on it. It would then turn back on then off then on, you get the point. Then it would be fine for a while bit start all over again.
So I fxz'd and started from scratch no dice still happening. I go to Verizon and got a new sim still happening. I just about smashed my phone when I tried Google one more time and found an obscure post in the nexus 5 board here at xda. Seems they have had this problem before but it was do to the sim tray or so they thought. One member ran a log cat and tracked down the culprit. It as a widget of all things transparent clock and weather. It seems this widget when updating location information using only GPS location (there is an option to turn off) deactivates your sim card. It's like turning airplane mode on then off over and over until it finishes the update.
I unchecked use GPS for location and no more restricted access changed messages. Hope this helps anyone with this problem there may be other apps out there causing this issue or it may be an issue with kk I don't know. The frequency of the problem is determined by the duration that you have set the app to update. I had it set for every 15 min. So it was driving me nuts. If you see this every few hours you may have it at a greater duration.

Very nice. Port is 4.4.2 lol. You still running it?

Actually not yet I thought it may have been when I installed your port so I went back to stock. But now that I know what caused it and you ironed all the little bugs I'm going to flash again tomorrow.

Sounds good!

I got the same problem today, for the first time on my Droid Maxx. Usually I do not reboot the Maxx for a long time, but due to recent rooting activities, the uptime was not much. And suddenly a few minutes ago, I saw the "Restricted Access Changed" message for the very first time.
I can see there are many users with the same issue on other Motorola phones in India, though. So this appears to be something common for Motorola.
I tried the GPS settings and it did bring the network back. I also tried selecting the other mode (default is Global) and select my service provider from the list, but registration failed. Finally I rebooted the device and the network came back. So, I am right now observing.

Constant "Emergency calls only" and no signal

Heyho,
about three weeks ago, my N5 suddenly lost it's signal over night and shows me "Emergency calls only" and it won't register into any network, just giving "Selected network unavailable".
When this occured my N5 had 4.4.2 stock ROM and rooted. I've unrooted it and updated to 4.4.4, but I still got the same problem.
Problem occurs with any simcard, while simcard works with other phones just fine.
Have deleted and reconfigured APN, but didn't make any difference.
I get a signal every few days, but I still can't receive text/calls or call/text anyone and my mobile data doesn't work.
I even tried to downgrade to 4.4, but that didn't solve my problem either...
I'm from Germany, but in New Zealand at the moment, so I really need my phone in case of emergencies and to stay in touch with family/friends.
I have been searching for a solution since it started, but have not been able to find anything that worked.
Sending it back to Google isn't an option right now because I am travelling.
I am really thankfull for any suggestions or if anyone knows how to fix this problem!
Cheers

Have you checked to make sure the network setting says 2g/3g/LTE preferred. Because I had this problem when it was switched to 2g only and was fixed by the above option

If the above fails trying going to your dialer and typing *#*#4636#*#*. Go into phone information and you should see a drop down box to select your network mode. Play around with those until you get a signal but you might not want to try CDMA options (WCDMA is ok) since you're on a GSM network.
Sent from my Nexus 5 using XDA Free mobile app

had exactly the same issue as you mentioned. Nexus 5 tends to lose network without any logical explanation and it tends to work at one place but stop showing network if you walk half a mile down the road (or may not show any network anywhere). Google has released an update in June in which they have updated the modem to solve the problem..given that I am in India and the June update was for India, Australia and Newzeland, it worked like a charm for me (all i had to do was flash the modem from twrp)..people as far away as netherlands have reported the modem to work for them..
NOTE: IF U INTEND TO FLASH THE LATEST MODEM, DO NOT FORGET TO TAKE A BACKUP OF YOUR CURRENT MODEM PRIOR TO FLASHING THE NEW ONE..

check your sim card. if you can, try someone elses.

Alright,
I've tried every thing again so far, but nothing seems to work.
Sitting in the library, I noticed that I get a signal, when connected to WiFi, which stays for 1-2 hours after disconnecting.
But I still can't make any calls or text and mobile data doesn't work though the APN is correctly configured and and data enabled.
I really hope to be able to solve this problem somehow, don't want to put aside my beloved N5 :/

Edit: Haven't found any solution so far and bought a new phone for the moment until I'm able to send it back to Google.
Might be an hardware issue and not software related.

Nearby wifi portal causes constant reboots/restarts

Hi, I am trying to get an idea of how many people this is affecting.
I am on my second T-Mobile Galaxy S6. The first unit had a hardware camera defect as well as this wifi bug. I had them replace it and the new unit's camera is good but it has the same wifi issue. Here's what happens:
When I go to an area with an "open" wifi network, a notification pops up on my screen that says "Click here to connect to null." What's strange is I have almost all wifi features off, particularly "Network notification." It should not tell me when any network is available. I also have "Allow Always Scanning" off as well as Wifi Calling disabled (not that relevant). Anyway, once this happens, I have about 2 seconds to turn off wifi or else the phone will reboot. It's a "soft" restart though, meaning it shows the Samsung and T-Mobile logo then is back on again within 5-10 seconds and fully "booted" within 30 seconds. This will keep happening until I turn off wifi.
It's not just any wifi connection that will cause the issue. I think it has to be an "open" connection that uses a portal for authentication (think universities, hotels, airports, etc). Recently, I clicked on one of the notifications (connect ot null) and saw a Cisco portal. I am not sure if it's isolated to Cisco AP's
I have found about 4 people so far that have reported this issue. I am guessing we are not the only ones. I am guessing it's a software issue.
Have you seen this?

Yes, I have the exact same issue. Sadly I dont know why it's doing it or how to prevent it. I'm located in the Netherlands and when I click login the browser directs me to a KPN Fon login page.

I am very confused what's causing this. Can you confirm what settings you have enabled or disabled? Wifi calling, advanced switching, always scanning, etc? I disable everything and still get it. So it seems like it's not just Cisco login pages. It's also FON. Do you have any areas in your city that have public wifi hotspots with login pages like McDonald's or Starbucks or a university? It'd be great to see if it happens at those locations too.

I don't have wifi calling, advanced switching is disabled, always scanning is on, keep wifi alive in sleep is on. I will check when in the neighborhood of public wifi spots. to see what's happening. Only solution for me now is not using wifi, but that's not very desirable. Have you contacted Samsung about the problem?

Yes they told me the same things you'd expect. First they said to restart the device. Then clear cache. Then try safe mode. Then finally to do a factory restore. None of these items work. Just curious, is there any way you can easily give me a dump (plain text list) of your apps installed, in a PM? I wonder if it's something software related. I can do the same but I just need to find a tool that can do it.
Edit: I found an app called "List My Apps" in the Play Store. I can't link you because I don't have enough posts under my name. Hopefully I can send you a PM with my list to compare.

wifi null and reboot Samsung galaxy s6
I have the same problem like other guys. My S6 reboot continously when the wifi is on and I am I'm the City ( Zürich -Switzerland)
Then only solution was to switch of the wi fi.
Anybody else expierencing the same issue?
Regards

I'm having the exact same issue. AT&T Galaxy S6 in Southern California.

How do we get this fixed? It's not limited to a provider (that's good).
I already exchanged a unit for the camera issue. I think I am probably past my date for another exchange and quite frankly the first one was such a pain to go through, I'd prefer not to. Anyone have any ideas? I am guessing it's some sort of software issue. Something trips it up when the phone is near a captive portal.

I'm not sure swapping units will help. I did that but it didn't fix it sadly. I contacted SamsungNL and they told me to go to a Samsung repair center to show them the problem. I will try to do that next week. Until then, mobile data only.

Hi guys,
I have contacted Samsung UK and they told me to bring the phone back and ask for a new one. This is not normal and we need a replace.
In the meantime I have try to install FXR wifi Fix and Rescue from play store. Did a reset of my WiFi with this app and since then Its working everything ok. No more Reboots in the last 5 Hours. I was also in public and crossed a lot of open networks but did not report more this issue.
Give it a try.

Samsung UK support are idiots. Seriously, they tell you to return the device for software faults. I contacted them about the LTE signal showing incorrect in the settings, a clear software fault, they said to return the device.
Honestly, Samsung support is useless.

I think no way to stop it atm bcoz it is a software issue, we'll need to wait for an update. I think the baseband of wifi/bluetooth is still not stable, today I heavily played with bluetooth and got a soft reboot too.
Luckily, my HK firmware got no wifi calling and any bugs, my wifi is fine.

This seems to be working. I also ran it and it fixed the problem. I think this points towards a faulty wifi database or something.

Thanks for posting this. It's the first attempt at a solution I have found. I am going to have to agree with others and say that replacing your device did nothing to help solve the issue. I think its a software issue, perhaps with the wifi drivers or database. I tried running FXR but I won't know if it worked til I get near a captive portal. Keep this thread going guys. This problem is frustrating as heck.

So guys,
I am Happy. In the last week (After I ran the FXR app) looks like the problem is solved for me. No one reboot and any problem with. Null or open networks.

Got 920f model but im not sure is the wifi problem on my phone or not. Phone keep rebooting itself in my pocket. 10 reboots minimum during the day. Tryed flashing another rom but same nothing changet. Not sure its a hardware problem or software.

Will a replacement fix this issue? I'm about to do it tomorrow. But I'd rather not do it if it's not necessary.
UPDATE: I replaced the phone, it did not fix the issue. Seems like we need to wait for an update, unless I am extremely unlucky.

I took replaced my device, but for a real camera issue, not the wifi bug. I agree with Stolpler, running the FXR app completely fixed the issue for me.
For those new to this thread/issue, let me try to explain what's going on and why a phone replacement doesn't work.
The issue is entirely software and I think what's happening is that for some reason, a small amount of us have some corrupted entries in our wireless login database. We all know that if you get a new Android phone and sign into your Google account, all your saved wifi credentials (home, work, school, etc) will be automatically migrated over. That's why you don't have to re-enter your wifi password. For some reason, one of these entries must have gotten corrupted for some reason. Another possibility is for some reason, the way the S6 expects the data/format is different than how Android normally stores it. So say you had an entry from your Nexus 5 for a hotel login. Then now that you're on your S6, it tries to read it and it doesn't like the format so it blows up.
Now, the reason why a phone swap won't work is the moment you sign in with your Google account, it will transfer over your wifi database/settings. If you get a new phone but don't login (ever) to your Google account, I bet the wifi issue would not exist.
With all that said, really, go download and try the FXR fix. It works, it really does.

[Q] wifi switches on and off

Hi,
since yesterday I have problem with wifi in my S7 (SM-G930F). It keeps turning on and off every second or two. I cannot switch it off because it keeps switching. I have rebooted my device, but it didn't help me. My phone is not rooted, it has stock 6.0.1 firmware. How to fix it? Despite it's impossible to use wifi now, it keeps draining my battery.

I saw it yesterday at work, but not authenticated. Now it is remembered in list. Sadly S7 has no option to forget networks out of range. Todays we have national holidays, but on Monday I will be at work and try to forget this network. I do not want to change rom because rom from my operator has wifi calling enabled and it is awesome.

Is there any chance that WiFi scanning is turned on? I recently saw that WiFi scanning will briefly turn my WiFi on then off repeatedly (shows with an indicator on top and I hadn't noticed that before). This first showed up when I installed Android Auto since it turned on my WiFi scanning option by default. As soon as I turned WiFi scanning off, the WiFi worked as it had before. It may be worth a look.

I've run into the same issue. Started yesterday, which may have come with the latest PJG update... Not sure.
But it's rendered my phone pretty much useless. The constant toast message popping up, saying "Network connectivity is available" gets in the way of the keyboard and I can't type a damn thing!
Like you, I've found it's stuck with reboots and a factory reset, which makes me think it could be the firmware or modem.
Edit: Disabling WiFi Scanning stopped the errors. Root cause is still unknown, though. I've never had to disable that before...

Yep. It was turned on, but I have it enabled since I bought this phone. Turning off neutralized my problem, but why it was broken for last few days when I haven't done anything with my phone? I rely on this feature because of localization accuracy and disabling it is just temporary fix.
edit:
Guys, one more thing:
do you have "Samsung Gear" app installed? I think this app is forcing to enable and disable wifi. Under localization it shows battery usage as high and it was updated last week

My phone does not have the Samsung Gear app installed. I do use Samsung Pay regularly and that was also updated (engine and app). I don't know how that would relate to WiFi though.

Turning off WiFi scanning stops the constant switching of WiFi. I tried removing the system settings permission from all the apps that had it (even the Google app) but it doesn't seem to have any effect.

I am seeing the same issue, I did not touch my screen in the following video

disabling "Wi-Fi scanning" in location helps.

Did the above solve the problem?

I am using G930F in US on ATT and encountered the same problem in past few days, where wifi kept turning on and off. Was searching this post, and found out that if i turn off wifi scanning i can get wifi to stay off (when i switched off ) and wifi on (when switched to on) and not flip back and forth.
go to settings.
- click on search
- type in improve accuracy
- select from choice
- turn off wifi scanning
Try that and hope that helps.

I have the same problem. The side effect is that it will drain the battery really fast.
As others have mentioned, after I have turned off the WiFi scanning in the location setting the problem is temporarily gone. However it should not be the solution as I really need the WiFi location to work. I don't know what is causing the bug.
P. S. I only see this problem starting from the last week or so. I leave the WiFi scanning location function on since I have bought the phone in May. Mine is Exynos version.

several Samsung devices have this issue.
I and several others have it on a note 4, and some people have also reported having this problem on S6 variants.

The problem is Google Play Services 10.0.84 version. Another cell phones with this version of Google Play Services have the same problem (ej. Google Pixel phone) but not all.

The problem is the Android Wear App. Deinstall the app and wifi works perfekt.
This issue starts with the last update of the wear app.
Hope i could help you.

I tried uninstalling Android Wear but it didn't make a difference. The wifi kept switching on and off.

As mentioned above, it's Google Play Services 10.0.84. Just disable wifi scanning until there is an update. Hopefully google won't take too long to push a fix.

loosing reception/signal on my s8+

Somehow my s8+ loosing reception all the suddenly.
phone has never been dropped.
i am loosing cellular signal all the time. no mattere where i am.
first i thought it was software problem, an did all the right things. safe mode, checking third party apps,
hard reset, an all that.
then i downgraded the room back oreo to see if it helped, no luck ;(
changing sim did NOT help either.
any suggestions? i have no warranty left on the phone as it a bit over 2 years old.

Mine is doing the same thing, even with wifi. It started after the most recent update. I have been googling, but haven't found much so I assumed that it was localized to me. I have never had connectivity issues with this phone before.

I am having the exact same issue, it all happened after I updated to android 9, even if you downgrade back to 8 it doesn't fix the issue, has anyone managed to find a solution ? Like henbone11 mentioned suggested sites with fixes from Google do not work. Thanks in advance

I was thinking bad modem software? Is it possible to get a older modemsoftware onto the phone with PIE installed?

Same problem here. Have not done any mods, always accepted the official updates.
Cant make or receive calls. (sometimes can make one or two calls right after restart). I do get text message notifications about missed calls. GSM data not working (sometimes seems to work for a bit but not enough to load a page or use maps.
WiFi and Bluetooth still work for me. so I'm using the s8 with another older phone for WiFi hotspot and calling.
Have done full factory reset, uninstalled all apps aso. Nothing brings it back - phone repair shops say they haven't heard s8 having these problems.

I have the same issue.
One day after I restarted my phone, it suddenly said no network connection. I did factory reset too, didnt fix it. Changed sim cards, still error.
I downloaded a widget that was supposed to turn the cell radio on and off. Cant turn the cell radio on either

Hi,
This issue is quite easy to fix. As modem performance (connectivity) is linked to model configuration. Another word for this is CSC.
It is fine to change your CSC. Download a benchmark tool to monitor your connectivity and record values and do not feel afraid to update / change your CSC.
It can take a while to find the right one for you, not it will be worth it. Don't worry.
Note: CSC changer can be easily found in XDA.
Note: a restart may be required to take the configuration into account.

What benchmark tool to use? And is there a tutorial for the process?
Thank you so much for the idea.
I moved to another country and used a local sim card, worked for a couple of days and then it's suddenly no network.
IMEi still ok.
Phone still detects my number.

Why would this work? Phone worked normally before. Same country/same provider. Sometimes still connects to data network for a minute and then drops all cellular connection again.
Why would changing CSC work.
Asking because changing CSC is not easy for me and I don't see why would I need to change it if it worked perfectly before. NFC payments worked(still work) , data/voice calls worked perfectly for 2 years. Then suddenly didn't.
