[Q] Are there any apps which can enable data roaming?

Hi everyone.
I noticed a very strange behaviour of my I9000 (2.2.1, JPY) the last weeks.
I am travelling a lot between Austria (Home country) and Germany. Usually i just untick "enable data roaming" as it is very expensive but leave data enabled.
From time to time, i use an adhoc connection to my laptop to update apps, synchronize with exchange to get the latest appointments, contacts, etc.
Now, in the last weeks i noticed, that all of a sudden (after the adhoc connection was terminated and the phone was idleing), there was a data connection. I am completely sure, that I DON'T enabled data roaming. Therefore there have to be anything else on my phone which enables this setting.
Is there any issue, that i missed - on the other hand, is there any way to examine this (Log or other sort of history) ? I know, I guess the easiest way would be to disable data completely in foreign countries, but this autoenabling of data roaming worries me...
Please, if anyone knows anything, please give me a hint, as it starts to get very expensive...
All the best, thank you for any answer,
ww
Update: i maybe have two suspects:
1. Background data (this was enabled when i last checked - maybe enable this (via E-Mail.app e.g.) enables data roaming too?
2. Auto update in market - i remembered that i ticked certain apps to auto update... maybe this is an issue...

Update: see my warning here.
Kind regards,
Michael

apps which can enable data roaming
I install LEWA OS rom for kingzone K1 turbo and in im not have Data Romming option. You have solution for dis? Or you know aplication to hepl me?

My XT860 weird sudden WiFi issue

Hello everyone, I know I am totally new to the forum but I assure you that before I wrote this, & before I even joined, I’ve been digging into all WiFi-related problems.
Before I post in this great forum I want to say that I owe all the developers here a BIG thanks, not only for development effort, but also for all help and guidance, it is you guys what make this forum and android community amazing! THANK YOU GUYS !!
The post might look long but I thought describing the issue in one brief post would be better in avoiding doing so in the form of many 2-line posts scattered through a 10-page thread.
Although my WiFi issue seems to me more like a hardware malfunction issue, it seems it’s one of its own where some indicators make me doubt it could be related to software too.
Here what the problem is about:
While I was messaging on WhatsApp, my phone suddenly disconnected from home WiFi & wasn’t able to reconnect anymore at all.
I now can only scan for wireless networks; here is how the problem takes place:
- As soon as I connect to a WiFi network, either it being secured or non-secured, the procedure gets stuck for 10-20 seconds at “Obtaining IP address from (Network ABC)”
- WiFi stays on but then shows “disconnected” or “Unsuccessful”, & (Network ABC) disappears from available networks list (unknown networks doesn’t)
- (Network ABC) reappears –> Device tries connecting to it –> Hangs in obtaining IP –> WiFi turns off
- I turn it on –> Device tries connecting to (Network ABC) –> Fails the same way –> WiFi turns off
- I turn it on –> Hangs completely in “Turning On…”, can’t disable or enable or anything, & got to reboot or battery would drain like crazy!
Things I tried (with no good):
- Resetting my WiFi router (other devices can connect to it)
- Connecting to other private & public routers that other devices normally connect to
- Fix WiFi using market applications: FXR WiFi fix and rescue, and Fix My WiFi
- Wiping cache & Wiping/Factory reset using the built in recovery on device
- Restoring a non-safe system recovery img that was created before the problem started
- Using RSDLite to flash the XT860 5.5.1-112 sbf available at sbf.droid-developers.org
- Safestrap: Wiped cache & dalvik cache, Formatted /system, then Wiped/Factory reset
- Connecting WiFi while on other ROMs (in safe system): CM9, MAVROM 4.5, DarkDroid 1.1, & the rooted deodexed 2.3.6 Motoblur.
Other info & symptoms that may help:
- Mobile hotspot not working in the manner of WiFi: As soon as my laptop or another device tries connecting to my XT860 mobile hotspot, the hotspot disappears from network list on my laptop
- The problem started during my first WiFi usage after the enabling of APN mobile network data
- When I switched on WiFi while Mobile Data was enabled, phone showed a successful connection to my home WiFi ! But stayed for a minute or two, then disconnected, then mobile data would hang & wouldn’t get disabled without a reboot
- WhatsApp chooses random tones when a message is received, even after the many flashes I did (this might sound geeky to mention lol, but it all actually started when I was using WhatsApp, which works using radio)
- GSM network and Bluetooth are working fine
So what do you guys think? What is the chance of it being about the drivers or something?
Or is it totally a hardware defect that grants me a replacement especially that it started while on stock?

Given it survived an rsdlite flash I would lean towards hardware. I know people have had issues with rsdlite not flashing properly, you could confirm by using moto-fastboot to flash the device manually. It's a command line utility, I'm not sure how comfortable you are using terminal commands

Thanks, I'll try the moto-fasboot way..
But what if it is really a hardware defect? I once read that rooting voids warranty, I mean with all what I've tried to solve this, would Motorola still provide a replacement?

Fastboot flashing removes the signs of rooting. Same as RSDLite. It's what they would do for a software issue, it pushes the factory software image.
Lots of people in this forum have gotten replacements after having rooted.

Wifi Authentication problem

Hi! I just bought my z3c and everything works except that most of the times, when I try to connect it to my home WiFi (Netgear DGN2200v3) I get an "Authentication Problem" message. I became aware of this issue when coming home and the smartphone would not auto connect.
I read somewhere that putting it in Aereo mode and then turn on again WiFi would do the trick, and in fact it does, but obviously this is not a solution.
I tried to:
- forget the network and reconnect
- triple check the password
- change wifi channel
- restart the router
- update the router firmware
- change some wifi settings on the z3c like switching on and off Optimize WiFi and Auto IP support
Is there anything else I can do?

Change the wifi security type.

Done, from WPA2 to none and back again.
However I just tried to reset my wifi settings with FXR WiFi fix and rescue and it worked. No more issues with autoconnect, no more authentication problems after a couple of tests.
My guess is that I had some previous backed up wifi profiles from google that were messed up, resetting them did the trick.

uh, I haven't needed to turn off google backup. maybe you should try to reactivate it, as new wifi data now are unlikely to be corrupted and can be backed up
I just wonder if my settings screwed up on z3c side or on nexus4, my previous phone.
well, whatever

Unfortunately didn't work for me.....

[Q] WiFi won't list nearby networks, But WiFi works

Hello everyone! This is my first post. I've learned a lot on the forums and I decided I would make an account today.
I've attached a few pictures of what is going on:
So I've had this problem off and on. So when I go to select my wifi networks in settings on my Nexus 6, it will show a blank list and it will say "wifi turning on". When I go to the notification pull down tab and see the wifi networks there, it shows up the list just fine! The only way I've been able to connect to wifi is if I download the app "WiFi analyzer" which will show all networks fine. So I know my WiFi works just fine, but for some reason in my WiFi settings, it doesn't show the list of available networks. I've factory resetted the device 3 times and that will fix it for a few days. Then it just has the same problem again.
I've already tried going to data/misc/wifi/wifi_supplicant.conf and erasing that and then rebooting the phone. I don't think it's a hardware problem, because this is my 2nd Nexus 6 and they have both done the same thing. Maybe a software bug? I've also booted into safe mode and it has the same problem where the wifi networks won't show up.
Some information:
Nexus 6
Rooted
Android L 5.1
Build Number LMY47M
Any help would be appreciated! My wifi works, but it's just bugging me that I can't figure out what the problem is. I don't want to factory reset my phone agian.

I stumbled across your thread while searching for a solution to a nearly identical issue on Marshmallow: notifications for open wifi APs would pop up, the pull-down status bar WiFi icon would list available nearby networks, but clicking on one would advance to the network setup screen that listed no APs. WiFi analyzer apps would list all the nearby networks with no problem. Your screenshots are essentially the same as everything looks in Android 6.0.1.
In my case, the problem was that I had used AppOpsXposed to block the Location permission from the Settings app. In AppOps, "Location" includes "Wi-Fi scan"; thus, the Settings app was denied permission to receive WiFi scan results and therefore listed no networks. There was no indication of this suppression that I could find in logcat, so it took me quite some time to determine the cause.
So, yes, it was my own damn fault.
In your case I doubt this particular problem was the issue because you were factory-resetting to no avail. However, I decided to necro your thread in case this happens to help someone else.

Question WiFi Problems

Hi community,
I'm writing because I have a strange WiFi problem with my S21 Ultra which I had with no other equipment before.
Setup:
- Galaxy S21 Ultra
- FritzBox 7590
- Fritz WLan Repeater 1750E (2x for better range coverage)
- WiFi 5G Auto channel WPA2/3
- WiFi coverage is good (tested with a lot of other devices)
Phone Setup:
- Paired with the WiFi
- Do Not use Mobile Data
- automatically reconnect to wifi
Problem:
The phone does not automatically connect to the WiFi.
The phone also looses the connection to the WiFi several times a day.
When the phone is not connected to the wifi I open wifi settings.
- It happens that the wifi list is completely empty and the circle animation indicates that the phone is searching for nearby connections
- It happens that the wifi list contains a list of wifi networks the phone has seen before when it was connected last to a wifi
- Switching off an on the wifi helps to find the actual networks and the phone then connects back to wifi (most of the time)
I tried already several settings and combinations but so far none of them brought any success. So I would like to know if someone else had a similar issue or has an idea what could go on here.
To me it seems strange that the wifi scan is not working as I would expect it. I would expect the phone to continously refresh the wifi list with networks it sees, but always when the phone lost its wifi connection the list is not working anymore.

Try tinkering with the wifi channels and encryption until it shows up.
Or you can try resetting the routers to see if it does anything

You said the phone loses connection and etc. Does that happen only at the location you described, or does it also happen at other locations?
It is possible that your phone also gets confused with the router and the repeater.

- Phone is on standby (placed on a table, etc.)
- I turn it on to check messages,
- No connection to wifi
- Open wifi manager
- No wifi networks listed at all
I do not know why my router/network should be the problem. All other devices in the wifi work flawlessly. It cannot be that I have to restart my wifi router every time the phone finds no wifi at all. That makes no sense to me.
It looks more like the android wifi service is still on sleep and does not report new wifi networks (which would be necessary also to see any wifi at all).

May I suggest....
Settings -> Connections -> Wi-Fi -> (three dots it top right) ->Advanced
Make sure "Turn on Wi-Fi automatically" and "Wi-Fi power saving mode" are both off.
If you use a repeater is it a mesh or AP solution? I find Android will drag its feet letting go of a wifi signal even when walking into range of another known network. Had an extender in garden and even when down to 10% connection on Wi-Fi it would stay connected to extender, I had to turn wifi off and on quickly to get it to pick a better network.

It seems to be the phone...
Definitely try what lywyn suggested...

you can also submit an error report on Samsung Members app, it sends reports directly to Samsung and get the feedback.
Download the app from the Galaxy Store if you don't have it on your phone > Memers app > + button > Error report

Unfortunately no success. I configured exactly like suggested. Does the S21 Ultra have problems with handover in meshed WiFi setups?

sometimes it happen when you connect at certain locations.

If you haven't already done so give this a try. Settings, search "Wi-Fi", scroll down to Location, Improve accuracy - toggle on, Wi-Fi scanning - toggle on.

Mesh is a single network solution so should not be a problem.
The only other thing I can think of is the power-saving mode. My son has his Pixel on power saving all the time and I know sometimes he has to turn off/on wifi to get a connection when waking the phone up

I found the issue! It is WiFi Direct related. The app "nexar" from the dashcam is interfering with normal WiFi on this phone. Nexar conquers the WiFi functionality and is responsible for my wifi disconnecting. The app requires the "Location always" permission. If I remove this permission my WiFi works again normally. So: one has a similar issue: remove "Location always" permission from the nexar app. In my case it helped.

You said the phone loses connection and and many others. Does that show up best on the region you described, or does it also happen at different places?
Kodi nox
It is feasible that your phone additionally receives harassed with the router and the repeater.
1st you need to honestly recognize if the issue comes from the cellphone or likely from your WIFI devices. Once this is clean, you've got something to go on with...
