Does anyone know if there is a limit to the number of "saved networks" Android Oreo and Google backup can handle? I've got over 400 at this point on my Sony XZ1 (yeah, that's a lot of travel miles ). When I recently moved devices these didn't get restored by Google on the new phone. The Sony Xperia Transfer software, which is usually pretty good for moving to new devices, won't even back them up, just says "No Data Found" for WiFi networks when setting up the transfer. I'm thinking it has something to do with the number of networks I have.
I managed to use g Cloud Backup eventually to move them and that worked OK, but that appears to have just moved the SSID entries and not the saved passwords. Maybe they do if one is rooted, but on that device I'm not. (and if I was rooted, my understanding is I might be able to just move a protected file anyway)
Anyone have any experience with lots of networks? I could have sworn I read a few years ago that Android itself had a cap on the number of networks it could handle. Thanks in advance.

I may be one of the few smart phone (HTC Rhodium / ATT Tilt 2) users who have requested to NOT have a data plan. I simply have no need for the service and have a basic call/text plan. I’ve decided to give Android a whirl with my AT&T Touch Pro2. I am having difficulty determining what services/apps/settings to disable to ensure no data usage is expended.
I have been using “Energy” ROMs for almost two years now and have been successful at ensuring no data usage is consumed. I few simple steps to turn off a handful of apps/services and I’m all set. Android, on the other hand, isn’t proving to be as easy….for me.
I have dug through the forums and searched around, but I’ve come up empty. I’ve found a few “nodata” programs, but they seem to all be outdated or for Windows Mobile. I don’t think my situation is very common, hence why I’m posting today.
I have successfully installed and used the latest Froyo build (FRX07.1, dated 01SEP11) found here: http://forum.xda-developers.com/showthread.php?t=1171052
QUESTION:
How can I stop all data usage while using Android?
ie...
a. stop specific services/apps/programs
b. install a "no data" app
c. any other ideas?
Thanks in advance for any assistance.
Best way is using the curvefish 3G/ON/OFF Widget, to quickly choose when to be online and when offline.
Can still use data without 3G though? It will just be slower.
What I do is make an internet profile with blank settings on my phone, set it as default then if it tries to connect it instantly fails.

This is a good solution by-design, same I used on my old nokia phones
But if you are looking for an app to handle that, try Droidwall (market)
Allows you to restrict which apps can access the network.
This is the perfect solution if you don't have an unlimited data plan, or just wants to see your battery lasting longer.

"Settings -> Wireless & networks -> Mobile networks -> Data enabled"?
Or you can simply install from market "Apn Droid"
Hi,
Is there an app, script or something (which MUST be lightweight for RAM and battery) that would turn off background data when wifi is off?

If you enabled background data at any point, you would know that 3G and 2G networks are only used when wifi is not connected. By turning it off when wifi is off would effectively make your data connection and plan redudant.
Disabling background data while is not on WiFi
Actualy, this is not a bad and dum question, these days, that many people have limited data, I really don't want my apps and other stuff on the background access the interent and I prefer these to get done on wifi, specialy market which I really don't want it to access the internet and check for updates while I'm driving, I would like this to get done when I'm on wifi, I noticed that my phone used 10 MB / day even if I don't use it myself.
please let me know if such a app exist
You can use DroidWall to get an exhaustive control over apps. Really easy to use, and you can decide app by app if they can get internet acces on 3g, wifi, 3g and wifi or not at all.

SORRY IGNORE ABOVE!! That is not what you're asking for. But you can use CPU tuner for that https://play.google.com/store/apps/details?id=ch.amana.android.cputuner&hl=en
Go to wireless
Then scroll down and last one choose
Then untick the one wich is ticked

I've tried each of these suggested options, but none of these have I found satisfactory.
The problem is that one wants to be able to retrieve and send MMS messages, without other data being exchanged (at least in my contract in Sweden, MMS messages are included in the contract, and is not counted as regular data. I'm guessing your contract is under the same premises...). So that rules out the option os switching off the 3G network.
Next, the problem with DroidWall in this situation, is that there is a 0.4kb data leak through the firewall every time the Wi-Fi successfully connects to a wireless network. Don't ask me how or why (I used two or three different apps to ensure that this was the case). Even if this data amount was fairly small, I wasn't satisfied, since I pay a correlating fee for every byte sent or recieved by my phone, and I wanted all other data stopped.
The solution I finally came to was simpler than I imagined. I altered the API (or APN) settings in the "mobile networks" menu found in the network settings in the device menu. I simply accessed the settings for my account and changed API-type (APN-type), so that it only said "MMS" (erase "default" and "supl"). The only flaw with this option is that one has to fill out "default" in this Space again if one actually desires to use 3G data for some reason. Anyway, this has worked solidly for me for a couple of months (no data leaks).
Hope this helps you!

Hey,
A friend of mine wants to lock the data connection of his 11 years old daughter's phone. So i thought, this would be easy, change the DNS as root to localhost or something like that. I read that it is possible to do so with the Wifi connection, but not permanent with the mobile data. This would just work for the current session, after a phone reboot, the normal mobile data DNS is back.
So my question is, what could i do, to lock every data connection? Is it possible?
Thanks for the answers!
why not just remove all apns and saved wi-fi networks? then there would be no mobile networks or wi-fi networks to connect to.
also, why does an 11 year old girl have an s2? if one isn't able to check on what their child is doing on the internet, and/or won't let them on the internet at all, might the s2 not be a little much?
This girl is not stupid, she knows how to connect to a Wifi network. Also it's thus a metter of time, till she knows to add the correct apn, or a friend of her does it.
I need a solution to realy change someting, that data is no longer possible. So she, or someone who knows a little bit about smartphones cannot enable it.
well that certainly is respectable, she knows how to crack wpa2 wi-fi keys?
then your dns trick, even if it were stored permanently, would be no use either.
i don't know, what country you are from, but at least here, every carrier offers the possibility to disable mobile data connections for your sim card. that way, no matter what you try to set up, the carrier would not accept you into their mobile network.
Could you delete APNs and wifi keys, then lock the settings app so the 11 year old cannot access it to edit the connection settings?
ZDBox is freeware and contains a reliable app locking tool.
I've noticed that whenever my wifi is on, and also the "always scanning" option is on - my phone suddenly connects to a network called "0x".
It doesn't really work - there is no internet. It happened in different places, inside and outside my country.
Does anybody know what it is?
UP
Old post, but happened something similar to me. Sometimes when I have just connected to my wifi network and I look on the menu it displays "0x". Your phone was probably connected to a public wifi or just bugged.
Still doesn't explain it though
In my understanding, the 0x is a garbage SSID that indicates that WIFI configuration data is obsolete.
Ite wonderful if u ask me ☺?
I booked a hotel room and when i arrived thr...my device got connected to Ox wifi and it has over 2Mbps speed...so i was curious about this Ox wifi hotspot so i searched on google and i found ur post and now i am more curios about it. What the hell is going on lol...
.
In my opinion it may have some connection with rooted devices bcz my device is rooted and i have samsung s8 as well and it neither finds this Ox wifi nor gets automatically connected☺:fingers-crossed:
Edit: As far as I see, it might a bug of Android with special cases of bad connection. Like it connects somehow, but can't get SSID. Turning on "avoid poor wifi" seems to fix it.
Same here. I've saved two wifi connections: one is my home network, other one is a network of free wifi transmiters offered by my ISP (UPC Wi-Free). My phone is Motorola Moto G with Android 5.1. It's not rooted and never has been.
I live around elder people and there were no strangers so I doubt some grandma suddenly established malicious network. Probably a bug, but the bug of what? Android? Some external software? I use Nova Launcher and Wigle Wi-fi. Do you?
0x seems to be prefix of hexadecimal numbers, but it doesn't make much sense. It wouldn't mean "hexadecimal zero" (which would be 0x0), but "hexadecimal nothing".

I've seen it too, then the actual SSID of my home network appears. Maybe Android shows '0x' when it doesn't know the name of the network it's on.
Well if I had hair on my head I'd be pulling it all out right now. Had this phone (US998) for over a month now and still can't get it to connect to the 2.4ghz interface on my router... (Linksys WRT1900AC running OpenWrt). It had this issue before I ever bootloader unlocked and rooted or modded in any way. It connects to 5ghz without issue. I'm able to connect to certain other 2.ghz routers but others it won't. I turned on verbose logging and when I connect to my router it says "Saved", then "Disabled" and then says "Network_Selection_Temporary_Disabled", "Network_Selection_Disabled_Association_Rejection". My other phones and devices connect fine to 2.4ghz. The list of things I've tried would be a mile long. I recorded a log cat while connecting to the network and have attached that. I see some errors and lines of interest in there under the various wifi sections and wpa_supplicant but can't make sense of them. I tried adding my AP into the wpa_supplicant.conf, I tried duplicating the settings in wpa_supplicant.conf in my other LG phone onto this phone. Tried various different settings in wcnss_qcom_config including setting band capability to 2.4 only, Phy Mode to auto, 11n, 11n only. Disabled 5ghz on my router then on 2.4ghz iface changed channels, channel width, SSID, password,tried different encryption & disabled encryption and set as Open, mac address, N and legacy mode, tx power, assigned a static lease to my phone trying differnt Ip's, disabled mac filtering and hide essid. On the phone i've tried static ip, third party connection manager app, wifi analyzers, network reset...and much more. I'm so frustrated and burnt out on trying to figure this out. I have the wpa_supplicant.conf file but I can't find wpa_supplicant in system/bin or anywhere else on my phone. I just don't get it, can't figure this out and really need your help. Thanks, Duh
I don't know what the exact cause of the problem was, but I upgraded my OpenWrt firmware and now my phone will connect to 2.4ghz. But my phone still won't do screen sharing even with my Lg phone and Lg Tv (LGUK6500 AiThinQ) both connected to 2.4ghz. Any Ideas?

Did you use any of the silly "debloating" guides? Someone else did and lost the ability to mirror to their LG TV.
My opinion it's silly, because we have found out with LG stock firmware many system apps are connected. By debloating what you think you don't need, later you do need or it causes lag -- because the system "looks" for it before moving on. Also the "packages" you are removing don't have clear labels as to what they do. Any guides written are NOT written by LG nor usually even Devs, but people who mean well but don't have access to LG database.
Better to "freeze" anything unwanted in Titanium Backup, than actually remove it.

No, it's been unable to do screen sharing even with a fresh install. When I did debloat I used the debloater magisk module and removed facebook apps, instagram, some games, and froze google photos and google movies
