[Q] Selective Mobile Network - Galaxy S II Q&A, Help & Troubleshooting

I've never seen anything like this and I don't know how I'd begin to search for it, so I'm asking here.
When I am at school, certain sites (like Facebook) are blocked, yet things like GMail are not. So I can either use the school Wifi (saving Data Usage and Battery) or access Facebook et cetera.
What I want to know is if it's possible to customise whether an app uses Mobile Network or Wifi on an individual basis. This would, of course, be ideal (but I've never heard of it). How hard would it be to implement?
Blah, blah, blah, discuss.

Use eNETraffic. It is a firewall that allows you to control each apps connection. Wifi and network. Works great. You have to be rooted though. Good luck.

[Q] free internet on android?

there are some app to make internet using for free? or some text files changes to do this ?
and were can i get custom rom torrents ?
sorry for my bad english
It's just impossible .
The easy answer: You can't. You either have no internet connection, or you pay some provider to have an internet connection. They have to pay for their network connection too you know.
The hard answer: Read Computer Networks (5th Edition) - by Andrew S. Tanenbaum. Then something like Hacking: The Art of Exploitation, 2nd Edition - by Jon Erickson. Hack into your provider's infrastructure. Depending on your country you will now face several years of jailtime. With some luck there is free internet access included.
NB: Actual punishable offense enactment is not endorsed by me. This is merely for personal enjoyment.
Sometimes there are proxy hacks that allow for free data, but most of the time you get extremely slow data rates and limited capabilities. Not worth it IMO. A data plan is well worth it's cost especially on Android.
Dont think so
I have never heard nothing about it....its not even possible
You can't get free internet in your mobile device, one way is only Wi-Fi but if you want free internet in every time on your mobile you need pay for network traffic.
It isn't worth the trouble to do this. And it definitely doesn't last long. Just use WiFi and stick to that.
Impossible ?
We need a contract for accessing internet.

[Q][REQ][APP] Wifi monitoring

I'm searching for an app on Android to monitor a wifi connection to see which people are on the wireless network.
I need this app for an assignment for school, a teacher asked to search for such app so he, and other teachers, can use it during the exams to see if students are cheating.
1 - Use your providers Data Connection (3G, GPRS, etc...), and cheat all you want.
2 - You don't need your phone to cheat... Even if you use your phone, you can cheat without any kind of connection (for example, take a picture of what you want to know, and use zoom). I'm from the time where we cheated on paper, or writing on skin.
3 - Even if you use wireless, your teacher has almost no way of knowing what others are doing in the intranet.
4 - Why do you want to help your teacher catching you and your classmate cheating?? Let him search for that himself.
That would however be a useful app to have, at least to check how many phones are connected to the router. Anyone knows of such an app?
It's some sort of an assignment, we have a course called network and datasecurity and we have to find ways to check up on wireless connections with your phone.
Wifikill. It's in the market.

Thanks! That really is a nice app!

[Q] Turn off background data if wifi off?

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?
Sent from my GT-S5830 using Tapatalk
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!
Sincerely, yitzhaq

[Q] Tethering without detection

I am very good at searching before I post questions, but I keep getting an error saying search is currently not available.
On my S3 there were ways to tether via WiFi and USB without being detected on my grandfathered in unlimited data play. Can anyone confirm that there is proven method via the LGOG. Ny phone is rooted, unlocked, custom kernel, snow rom, and various other mods.
If someone can confirm a working way of doing this, I will provide them with file hosting and subdomain on my server, with full ftp access... etc. Thanks!

Also, let me know if this is in the wrong section
I used the native tethering on SnowJB fairly heavily without issue and as far as I can tell it was never detected.
I was rooted and running various ROMs on my Samsung Infuse a few months ago, and I got an email saying they would add the tethering service to my plan if I continued to use it.
A couple years ago I had a jailbroken iPhone and tethered a lot of data and never had an issue.
I have not yet tried on the LGOG in fear of getting a $40/month service automatically added to my bill.
Sorry I don't have an answer, just sharing my experience I've encountered while tethering.

avoiding detection would probably mean using a method that doesn't rewrite the TTL's on the outbound packets. I've used wifi-tether w/o issue as have many others, I'm sure. I suspect that wifi-tether doesn't preserve the TTL's, but people get away with it because the cost/benefit to carriers is to pick the top 1% of bandwidth users and examine their usage for good reason to stop them somehow, illegal tethering being a good convenient one.
I'm sorry I don't have a solution for you, as I've also searched for just such a thin and not found it. I am curious what others are doing for tethering on this device, though.
If used sparingly, you PROBABLY won't get caught. I used foxfi on my old phone on different occasions and never recieved any notifications about tethering.
jonasl (if you don't recognize the name, he is very good at what he does) had a post in the SnowJB thread a while back about fixing the tethering issues people were having. From what I understand of it, the tethering checks to see if AT&T customers have the entitlement to tether, but since this is a ported ROM, it isn't able to find out if you are entitled (the code doesn't exist to finish the check). His fix circumvents the check (which as he says "This will as a sideeffect also give you tethering even if you aren't paying for it").
I have implemented the fix in case I needed it, but have not had a need to tether since, so I can't vouch for it in that regard, I can say everything still works as expected.
jonasl's post
If you really want to avoid detection, you could run a socks proxy on your phone that forwards to another socks proxy on the internet. Then you need a way to use the socks proxy on your phone. On the client side it can be easy (web browsers have a socks proxy setting, and there are wrappers to socksify anything on your pc) or harder (if you're tethering a tablet or game console or something). Finally, you need a way to bring up both your wireless and mobile data connections at the same time - you could use wifi tether for this if you only need to tether wireless clients, or a more manual method if you need your phone to be a regular wifi client on your network.

[Q] How does a carrier know if a user is tethering as a wi-fi hotspot?

I am currently using Straight Talk, and found that the Android built-in "portable wi-fi hotspot" worked right away for me in seconds. I know this is against the terms of use for Straight Talk, but how can they tell I am using it? I would like to be able to tether my laptop once in a while (perhaps 100 MB/month for work when I can't access wi-fi). How would they know? Couldn't Android apps be coded in some way where the carrier cannot tell that an external device is connected?

well, using a laptop takes a lot more data, then say using your brower on android. so the upstream and downstream of data being pulled would be a dead givaway
? I didn't say what I was doing on each device. I probably use 1GB/month on my phone, and as I said, maybe 100MB if tethered.

It's called packet sniffing. They know what browser you're using, and what websites you're visiting. They know you're not using the phone to browse, but rather a computer via tethering.
The way around this is to use a virtual private network (VPN). VPNs are a service you pay for, monthly or yearly.
Another way is to use PdaNet+ and USB tether to your computer. PdaNet has a companion program that you install on your computer, and there's an option to "hide tether usage", which creates a VPN between the 2 devices. It has a bluetooth tethering option as well, but connection speeds won't be as fast. PdaNet+ is $8, which might seem a bit high, but it's only $8 once, and the freedom it gives you is well worth it. I USB tether my phone for my home internet, have been doing it for months with T-Mobile's unlimited high speed, and use a ton of data (100gb+...one month I used nearly 400gb).
If you have no carrier provisioning (ie: a Straight Talk tethering app) on your phone, it's possible that you can use a browser plug-in that masks the browser. In other words, instead of your Firefox browser being detected as for PC, you can mask it as Firefox for mobile, or Chrome mobile, or whatever. YMMV, and sites will tend to load up the mobile version, which can be a bit of a PITA.
It is not illegal to use your data as a wi-fi hotspot. FCC law. It's not against user agreements to do so either, except for certain circumstances (like running a server, but you're not doing that anyway).
