What the heck is phone visibility? - Samsung Galaxy S8 Questions and Answers

I know that is apparently supposed to help you transfer files but how. There is no info on it at all. Argh!

this bothers me as well. anybody knows the technical side regarding "phone visibility"?

It's network discovery, if you're on a shared network you can either hide or show your IP and the services available from your device.

cannot seem to get my email on my xda mini s

Hi there-I cannot seem to get my email on my xda mini s set up properly. I am on a pay as u go account for my mobile can that be a problem? I also use webased email as opposed to outlook/outlook express. Anyone got any suggestions? If I am at a wifi hotspot I can try to connect but never seem to-that is to free spots I am talking about, not trying to leach off an open node. It is very frustrating.
Hope someone can help

How will "they" know if I tether with a rooted Nexus One

Just read Tmobile is going to charge for tethering & wi-fi hot spot. How will they know? Isn't data, data? I don't want to be charged for something I might use 5 times a year.

I don't know if they can tell, I have used the hotspot feature with my Nexus quite often and AT&T has never tried to charge me.
They wont.

the only way they could know if you are tethering is if you are using the carrier's native ROM, i don't think they would ever find out when running a custom rom.
If you don't bother searching - at least do read the same thread on the same 1st page of the forum, instead of opening another one.
Einstein was right about infinite things...
Packages being sent contain HTTP requests, which may contain info on the device that's being used, among other stuff I don't really know about.
If those packages contain specific info on the device, they probably can tell even if you're using a custom ROM, just by putting some effort into it.
Anyways, if by some mean they'd manage to analyze it in a way where they can tell whether you're tethering or not, we'll also find a way to trick them by parsing those packages on the fly.
So, ultimately, I don't know whether they can tell or not if you're tethering, but if they can don't worry, someone will take care of it.

That's screwed. You can set any UA when using a custom ROM, so you'd be charged for tethering when you set it to Desktop?
In that case, someone might have a good reason to sue them...

First, you're right. But I forgot to mention that they won't charge you, it simply doesn't work. So if you changed the UA the way you suggest, you would see a blank page and quickly fix that
Second, I noticed after answering that I didn't read the question well (sh*t happens ) and didn't get the point about root. So to be more clear about the original question :
- "They" shouldn't be able to know if you're rooted or not, but there may be ways for them to detect that you are tethering.
Tethering and T-mobile...
If you run speedtest.net on a computer that's tethered to the N1, it shows on speedtest.net's server that you are on T-mobile USA's IP. Somehow T-mobile would have to acquire when the tether option was turned on and off at the same time the 3g service is on. They would have to submit that into the header files that get sent to their services. That would be a stretch, but it would be doable in future software updates. Say Gingerbread....
Actually, yesterday I've found something interesting about one of our local carriers.
It has 2 APNs: one for "dumbphones" and one for smartphones.
The first one allows Nexus to use internet and market, but tethering doesn't work. The DNS requests are blocked - I still didn't figure out how they block them. DNS servers get the ping, but the requests aren't resolved. Yet it looks like they're resolved, if sent from the phone.
The second one allows full internet access for the phone - and tethering also works.
So they don't detect tethering (and don't charge for it), but looks like they can block it with some restrictions that still allow the phone browser to work, when using "dumbphone" APN.

so all the other data, non browser based - how do they decide if/when to block which data ? i'm assuming this will only work on a non-rooted phone, or they are breaking the law and doing deep inspection.
if they =are= doing deep packet inspection, they can and will be held liable for eavesdropping, child porn, online harrassement (if you ever harrass someone), and a whole host of other things.
the ISP (tmo) not knowing what you're doing is a benefit to them. ignorance is bliss, and knowledge means responsibility the way the gov't views it.
lol, that last statement, the gov't and responsibility could be a joke i guess.
I believe they just have all traffic going through proxy which allows only very few selected packet types through, and blocks the rest for "dumbphone" APN. They don't check/block anything beyond DNS requests, and if you want to connect to a site while tethering "dumbphone" connection by IP - I believe you'll get there (didn't have a chance to test, but pinging IPs works without problems).
And of course, my Nexus with Enomther's ROM was used for experiments and showed exactly the same behavior.
The thing is - if I understand it correctly, it's not a planned behavior. They wanted to shut off all the network but the sites they give access to from their own WAP portal (considered "internal" internet), but in fact for some reason Nexus isn't completely blocked by it. PC is, though, when connected through Nexus.
And again, they don't have something that detects tethering - once a smartphone APN is used, the traffic is the same for Nexus and for tethered devices.
Some technical info...
Hello!
There is a way to detect if You are using tethering. Basically - tethering is routing - adding one more point in communications. So - if You just use Your phone, packets are addressed from/to Your phone. But if You are tethering - packets are addressed to device behind phone (using phone as gateway, basically router with NAT).
So - they may check:
ARP tables
TTLs
OS specific packets/DNS requests/used IP's (Why would Your phone check for MS updates? )
other things...

[Q] Galaxy Tab and corporate LAN via WiFi

Unfortunately I don't have a Tab yet, and it's going to be my first Android device, so not much I can help you with. Hopefully someone can help u here from the board! Maybe asking in the Android section of XDA too. Good luck!
I regularly use EAP-TTLS/PAP on my Nexus One, so its not a general Android issue. I never came across PEAP, so there could be bugs... You need to talk to your network administrator to log your login attempts if you want to debug this.

1 Method to Circumvent T-Mobile Tether/Hotspot

Time for me to update this thread!
For all of the T-Mobile users who are still trying to find a way to circumvent the user agent checking that T-Mobile does while using a third party hotspot app and don't feel like decompiling, editing XMLs, and recompiling, or messing with editing APNs, or ETC... A simple solution that I'm using; use a VPN.
Search the market for: Hotspot Shield
▼ ▼
https://play.google.com/store/apps/details?id=hotspotshield.android.vpn&feature=nav_result
▲ ▲
Also DO NOT use the native hotspot, I state this because of all the edits I've tried, the native hotspot still connects to the APN: pcwebs.tmobile.com instead of epc.tmobile.com - Which sniffs out the user agent of your browser and sends you to the upsell page.
If you're on the Galaxy S3 and JB use this app by TrevE

All others that are capable use Wifi Tether for root users.

-----------------------------------------------------------------------------------------------------------------------
1 - Start Hotspot Shield. (As of 10/18/2013 If you select to "Restore Purchase" Redeem code is "FREE" it'l give you 30 days of elite service for free!)
2 - Wait for connection to establish and a "key icon" to show up in your statusbar.
3 - Start Wifi Tether for Root Users or TrevE Mod which ever you're using.
4 - Configure wifi tether settings.
[For SGS3 users on JB using WifiTether_TrevE_Mod Version 3.2-Beta2-041713, I've found the best setting to use is as follows:
Device Profile: Generic ICS/JB (wlan0)
Setup Method: Auto
Wifi Encryption: Your Preference
SsID: (whatever you wanna use)
Don't disable bluetooth: Checked
Wifi driver reload 2: Checked
Enable Access-Control: Checked
MMS Clamping: Checked
Routing fix: Checked
---------------------------------------------------------------------------------------------------------------------
5 - Tap icon to start tethering.
Once all of the messages stop popping up... Enjoy!

Optionally:
If you wanna setup your own personal VPN - G.I.Y.F. (Google is your friend) Search for OpenVPN methods. PPTP also works.

It, in my case, is caused by having Xposed Framework installed. The only fix I've found for it was to Titanium Backup my apps, then uninstall the Xposed Framework - requires you to boot into recovery and flash the zip file "Xposed-Disabler-CWM.zip" then you have to Wipe Data/Cache/Dalvik/Fix Permissions, flash your rom again, and restore from TB.

The way a VPN (Virtual Private Network) works is by anonymously masking ALL network traffic to it's destination. I hope my explaination can help those who doesn't understand how a VPN connection work. Here we go:
Normally -
A mobile device connects to service provider monitored internet. In T-Mobile's case, packets are sniffed out that contain any form of user-agent strings, and if the strings report anything other than a mobile device, internet connection is denied and you are redirected to the dreaded "upsell page".
Think of it as water with particles in it passing through sand before reaching the well of water below the sand.
If the water is your network traffic the particles in the water would represent your user agent and the sand is your service provider's filters; not all of the particles will make it through the sand and into the well if they arent small enough to pass through the grains of sand.
Using a VPN is kinda like shoving a tube through the sand and sending your water & particle mixture through the tube directly into the well below. Everything makes it through whether the particles are big or small.
Sorry its late and I probably used a bad analogy. Anywho I hope it made a bit of sense. Lol
I can help you set up your own private VPN. The problem is there's some many different types of routers available for everyone to use. The PPTP type VPN is actually set up through your router. For most people there will be an option to utilize the PPTP port within your router setup screen. Open a web browser, type in 192.168.0.1 or 192.168.1.1 or "routerlogin", the webpage will ask for a username and password. If you changes it, whatever your username and password is. If you didn't, the default username is "admin or administrator" and the default password is usually, "password" dig through the available settings you have and let me know if you have the option to enable anything labeled "PPTP" also let me know which router you have.

yea, so basically, you'd have to setup and only use at one place? is there a solution that will let you tether to any computer anywhere? like is there something you can just setup on the phone? I mean something we can setup as opposed to this 1click vpn which my guess is won't stay free for long.

You actually set up your home network to host you own personal VPN. So no matter where you are, your phone would always use your home network.
Your phone will still use the service provider's data service, however, it would use it only to connect to your VPN at home and then securely reroute that data back to your device. So as all of the data is moved along T-Mobile's servers the data in your VPN cannot be read by tmobile's filtering process.
So one personal vpn server would be all you need. There's an option if you check your "settings -> more settings -> VPN" that will let you use a VPN for all connections on your device. Let me know if there's anything I can clarify.

Just remember the hit on network performance. Your home network is downloading from the net, encrypting it, and uploading it to your device. This assumes you're outside your home network.

This is true, its not that bad of a lag for me here in Chicago however, normally my download speeds are between 5-7 Mbps on 4G, with the VPn running I drop to 3-5 Mbps, but I've kinda tweaked the tether apk to start OpenVPN when tethering starts and to disconnect when I turn off tethering. So for the most part I never notice the hit on my speed, I've configured packet compression on my personal VPN server. I'm using a Linksys E4200 on AT&T U-Verse. Thanks for pointing that out for me by the way Reilly, I know I've forgot to list the pros and cons of a vpn, I have a few minutes in my hectic life to hop on xda and make a few quick posts but never enough time to go into detail and proof-read my own posts.

Lol, originally I started looking for a way to bypass UA checks because I wanted to update my laptop which reports UAs as Internet Explorer through the Windows Update Center, and my Xbox 360 which also reports as IE when connected to Xbox Live. I didn't really need tethering until then. But its a pretty convenient function to have when I'm out and about.
Glad I could help out the other users on T-Mobile, lol I guess as the slogan says, "Stick Together"

Hey, thanks for the info. If you're using a VPN it should work with most wifi tether apps though, shouldn't it? I'm on a N4 and CM10.1, which I guess should have about the same tethering app as the stock firmware. Also, it should work with BT tethering, shouldn't it?
Another question, is VPN One Click really free, or is there a catch? My router doesn't seem to have the VPN option you mentioned before, and my home internet appears to be 15mb down, but only 1mb up, which would limit considerably my speed even if I did a personal VPN.

I use Wi-Fi Tether for Root Users and it works fine with VPN.
I tested with the native app, but it doesn't connect to the internet. So that's that.
With Wifi Tether for Root Users, it worked once but in a very flaky way. After that one time, couldn't get it working again. Tried many different profiles, and the one in which I don't get any log errors is forcing the generic one, forcing one of the setup methods. Apparently it doesn't work with the N4, there's another N4 user in the reviews that has problems too. Another very similar app is Open Garden's wifi tether, but it seems to be pretty much the same app as Wifi Tether for root users, has an almost identical interface and options. And of course, also doesn't work. Barnacle is another that doesn't work with the N4. By the way, this is all without even using VPN, so those aren't viable for us with the N4.
