Advice on Dual-SIM/Android for work or persona phone - General Questions and Answers

Hello,
Trying to search for an answer I went back to threads from 2010 but without luck.
Currently I use a Nexus 5x with OmniRom 6.0.1., XPosed and microG with a Focus on privacy and security.
Until now I successfully refused to use WhatsApp but with new job/people/place it seems I'd need to hop on the bandwagon.
I had to get myself a new phone number (sim card) in this country and would like to use my old number too for my old contacts. A dual-sim phone makes sense there.
Now my question; how/is it possible to run two android systems on one phone at the same time, both with dedicated access to only whitelisted (XPrivacy eg.) data?
For the one sim card my usual privacy focused take, the other sim for WhatsApp/Google/Facebook - all those so called "social apps".
I don't want my data getting mixed up/tracked down/profiled with my other sim card and keep ist usage to a minimum. Mostly just reading group messages or posts
by other people.
From what I read, Google "Android at work" needs its own Business Server running for it. Won't work for me. I also remember Blackberry had a take on a private and work space once.
Or do I have to trust in/depend on the original phones software to manage the sim cards access?
What kind of software/hardware solution would you suggest to me? Regarding phone specs I'd prefer a good camera, ~ or <5" display (not >5") and a price as low as possible, ~ € 250.
Thank you!

Complaining to the right People at T-mobile

Hi Everyone,
Ive been on a bit of a mission with T-mobile and have been in touch with the directors office, they are under the impression that nothing has been locked down on the phone in rc7/rc30 that would limit the use of the phone from a development standpoint.
Ive given them a few examples of things that cant be done but they refuse to do anything (other than cancel my contact if i want) as im only one person who is complaining.
I know everyone runnning rc30v1.2 and rc8v.12 is ok atm, but could EVERONE please send a little email of complaint. Just explaining that you are unhappy that they have locked down the phone and denied us root.
cl&[email protected]
They say that if they get more complaints then something will be done
ITS WORTH A SHOT ISNT IT?
PS... If anyone wants to cancel their contract in the uk because of the lack of access, call 01707 315000 and ask to talk to Leah within the Directors team about your G1 problem. I explained that i couldnt get my apps working because i couldnt edit/add files to system directories.
They should offer to cancel it, it worked for me
Yeah, it's worth a shot, although from past experience with T-Mobile this may be akin to trying to extract blood from a stone
I tried doing the same thing after I got my G1 (before anyone figured out the hole in RC29). I found the people over at T-Mobile USA are just as clueless. As soon as you mention the words Android or G1, they instantly transfer you to a different support queue. I tried to explain what root access was and they didn't have a clue what I was talking about.
I found that here in the UK also, these people work in the directors team and so far have not fobbed me off.
They dont claim to be technical but are at least talking to the T-mobile developers about this. They have raised my concerns with the UK G1 manager, i think my case just needs a little more oomph from others complaining.
I've already called HTC, G1 support, and the PDA/Smartphone support ppl. None of them were willing to even try to understand the issue.
T-mobile have just called me and have advised that we should expect a statement about the issue by the end of the week. The issue is now with board members apparently
Maybee they are actuclly starting to understand??
You should have them email. At least that way it leaves a paper trail.

That's very interesting that T-Mobile is even considering the idea of allowing root access, to the point where it would be an executive decision by the board members. Do you have any other information on this aside from your first post? Can anyone else confirm this?
i phoned tmobile uk today and asked why i couldnt get root on my tc5-rc8.
and i had a long talk with the guy and he said he had a email about this issue
and went throught a few things with me on my phone. and then he said he would phone me back tomorrow with someone that new more about the g1 then the tec support staff. and he would be able to give me more answers about it.
qtronix
Cool
Sounds like my insessant *****ing at T-mobile support might have gotten us somewhere?
At least techies are not fobbing people off at the moment.
Could you please concider sending an email to the address i posted, just so they are aware that others are miffed.
******This is a copy of the email i sent to the directors team******
Leah
Many thanks for your call....
As t-mobile dont seem to see/understand the problem I have given the contact details of the director team to a group of developers so that you can hopefully get a few more calls about this. Please believe me that I am not the only person who has these concerns, but when people call tech support about this they are simply fobbed off by people who are not trained/do not understand the issue.
I would like to point out an error with t-mobiles response that they have in no way locked down the phone so that it is detremental for putting developed software onto the phone.
Please see a few examples of how the new RC8 Software limits Developers :-
1. Say I wanted my screen to automatically rotate without wanting to open the keyboard, this is simply a matter of editing offset: 1104724 within /system/framework/framework.odex to 0x0F001246.
I could do this on the old software but not on the new RC8
2. Say i wanted to update the web browser to do the same, this would mean editing the origional browser source code released by Google and putting it on my phone. Again, this was possible with root access on RC7 but has now been made impossible on the new RC8.
3. Say i wanted to make a tethering application that allows me to use my G1 as a modem to my PC (i know this would cost me money on my contract for data transfer) but I might want to do it so that i can connect to my workplace vpn to fix something. This was Doable on RC7, but now is not.
4. The G1 currently has no way of clearing cache for the marketplace, this again was doable on RC7 but not on RC8
5. The G1 has a limited ammount of space to install applications. It would be a good idea if we could install applications to our SD memory Cards, but again we cant do this because of the new software.
The above examples are just some simple things developers are working on that would benefit the phone, but we cant develop them and put them on the phone.
Basically anything that means editing a system file / writing a file to a system directory is now impossible.
Please understand that developers are not trying to take over the world or ruin the phone. We are simply trying to make the phone do what we want / improve the features.
This is how OpenSource works. Everyone has access to the Source code so that it can if neccecary be customised/edited to improve things for everyone.
The new software has made it impossible for programs that interact with the main system files or require extra files to be put in a system folder, to work.
Developers understand why the phone RC7 software was unsafe in the way it ran commands, we understand why you fixed the command running problem, but instead of fixing the issue properly you have just locked down root access?? Why??
If the new software in no way limits what developers can do, then why when you search on the net are so many people “Jailbreaking” their phones to get the access they require.
http://arstechnica.com/news.ars/post/20081105-android-liberation-t-mobile-g1-jailbroken.html
Can i draw your attention to
"In contrast, the G1 has been developed by the Open Handset Alliance project. It's extremely unlikely that this alliance, which is committed to an open platform, will engage in the same kinds of protective shenanigans that Apple has resorted to. The Android philosophy states that "anyone can contribute to Android and influence its direction. That means that anyone can download, build, and run the code needed to create a complete mobile device."
So why jailbreak an already-open device? One big jailbreak advantage is that it allows you to bypass the G1's internal storage. Until now, you were limited by the G1's built-in memory for installing and running programs. With the jailbreak, you can install applications onto a local SD card and run them from the card. Running low on memory? Just swap cards in and out.
Jailbreaking also allows you to use low-level tools that run in the background. Want your G1 to call home and report your location every 20 minutes? A simple Unix process, called a daemon, can handle that for you. You can set daemons up to remind you of appointments, to scan for nearby wireless devices and more. The world of handheld computing doesn't begin or end with graphic interfaces. There's an enormously rich world of possibilities available through command line processes.
Most importantly, jailbreaking gives you complete control of your system from the bottom up. It lets you stop thinking of your phone as a handheld gadget and start using it as a fully-capable Unix platform. "
Please could you explain how T-mobile are of the opinion that they have not limited developers with the above examples in mind.
The G1 is being sold as a Developer friendly OpenSource Phone. How can you claim this is developer friendly when the software severely limits what developers can do?
Are T-mobile saying that the phone was never supposed to allow users this access and that the RC7 root access was a mistake?
Eagerly Awaiting your response..

Well written, although I would have DEFINITELY left out the part about tethering the phone.

I did think about that, but then i reconcidered as we already have tetherbot which works without root.
Suppose we will just have to see if anything comes of it

you can always call t-mobile and say that after you updated the phone it is now:
constantly feezing, apps are running slow, and at times you can not connect to internet.
also tell them that you tried a factory reset and it did not help (make up a story that you have friend that has a lot of app and his phone runs faster than you phone with no apps installed)
if you have insurance they will send you one for free, you just have to return your old phone,
i believe they are still sending out rc29 for replacements as of now.
friend and cousin tried it and it worked.
might be worth a shot
Just got this in my inbox:
"Thank you for letting us know of your concerns with the 'open source' and 'root access' on your G1 mobile phone. We really do appreciate your comments about this.
We're aware that there are concerns in relation to this and our leadership teams in the UK and the USA are currently reviewing your comments and our position. We plan to provide you and other customers with similar concerns, with a response early next week, which should answer your concerns. I'll be in touch with you then.
Your comments are extremely valuable to us Mr * and I'm grateful for your patience while we look into this. I'd like to thank you personally for your co-operation.
In the mean time I hope you enjoy your weekend.
Kind regards

Of course, their answer could be anything from "f*ck off" to "yes, we'd love to embrace the openness of android with both arms, here everyone, have root!" so we'll all have to keep our fingers crossed 'til monday.
Well I just hope they release an update with options that allow us to turn off all background services (myfaves) and unwanted datatraffic (or actuall prevent overriding options when roaming).
How did that dead horse like the beating?
Perhaps a dead horse. Could it be that Tmo has now figured out that with root access, it won't take long for people like the coders at XDA to fully jailbreak the device to the point that voIP will be easy for any user to obtain? Are they just trying to protect their ability to profit off of voice traffic?

Hummm... I think ALL wireless providers are threatened by VOIP but the main reason root access was blocked was due to bad press mainly by tons of articles stating that there is a huge security risk and a flaw was found with Android which could let remote users attack someone's device...blah blah blah and so forth. That pretty much scared T-Mobile and Google which hated to have bad press so close to the G1 just being released and were forced to correct this issue. The only problem with that protection came with closing alot of freedom for the G1 and may happen to alot of more Android-based devices in the future, I'm afraid... Maybe Google will realize that there are other ways to protect mobile hijacking (which is extremely rare anyways) by creating some type of built-in firewall software instead?

Root is not necessary to build a voip app. Fact is, G1 launched with a skype-compatible voip app called iSkoot. Look it up.

[Q] Help Needed: App Development for Field Data Collection (MS Access)

Guys, I am in need of inputs from you regarding a query that I have.
I work for a corporate group in India and am looking for some technological solution to replace the pen and paper survey questionnaires for field executives. The device I have shortlisted is Samsung Galaxy Note.
Basically I want an application which
- is compatible with Microsoft Access (I have asked our IT guys to develop a survey form)
- is easy to use for field executives for data entry in the form
- is able to send/sync the filled in data to the server wirelessly (3G/EDGE/Wifi)
- is able to connect the device to a pc and reproduce the data on a pc
- is user friendly and bug free
Please let me know if there is already solution available for my requirements (which I may have overlooked) and if custom developed, how much this application is going to cost me.
@ Mods, I searched the forum but could not find any relevant post, hence starting this thread. Feel free to move it to correct section if necessary.
Thanks and looking forward for your replies.
Ace
BUMP... No reply!
Is there no one who could offer some help and direction for me here?
Hi,
don't know if you already soved your issue but I have a suggestion: Memento
I have the same problem you do and have been searching forever. The best I could get was memento (from the market). It has a one time cost of 9,9 USD and it lets you create your own data forms. Everything is stored locally on the device and it can be synchronized (to google docs in my case).
I've been operating 7 devices with this solution for the past 6 months and it works prety well. It cannot do everything I need, but it was the best I could find.
Other than this there are other solutions but the costs involved are a lot higher (something like 10 to 20 USD per month per user)
Hope it helps
Cheers

[Completed] Possible to completely disable 2G 3G ALL data on Android ?

Possible to completely disable 2G 3G ALL data on Android directly using some Software on PC or Phone or via MDM?
There have been cases of some people I know (older family) that were brought an Android phone but inadvertently some Data was used without a Data Plan - more expensive.
Lets say instead of buying Feature Phones for some delivery boys, we bought Cheapest Android phones possible - The boss there just wants Phone calls with them and wants to ensure the boys wont be able to Rack up Data use/ bills on the phone -
Are there ways to Disable Data AND/ OR WiFI? Selectively or so? Maybe only have it on when being configured by MDM?
Please point of ways that this can be done.. Or point to forums where this information can be ascertained.
Thanks.

dr.fone toolkit - Android Lock Screen Removal with encrypted phone ?

Thank for any help !

Do you know the answer ? Please ?

Hello,
The Galaxy S7 has multiple variants and builds. Normally when asking this kind of question, you should include the model of your device. That way anyone wanting to help you actually has the knowledge to be able to do so. Phones have different internal parts, memory space, and so on. You can find your model number by doing the following:
- slide down the notification bar, sometimes you may have to slide down twice depending on the device. Click the gear in the upper right hand corner. "Settings"
OR
- Access your app drawer or all apps section and find your "settings" section/app. Most of the time it will have a icon of a gear, or three lines that resemble on off switches. Older androids sometimes use just have three lines (as the settings icon)
- Find the section labeled "About Device / Device Info" its usually labeled something similar if not exactly. Open this section
(Galaxy phones usually have this section at the bottom of your "settings" section)
- Somewhere within this section, there will be a label that reads "Model" and that is your specific variant which is needed in device specific situations.
* Take Note of this for future reference. You might think okay ill remember that. But when you come to realize your devices model number may be XDA-2017T1 and you look for something pertaining your device. You will also find something like this:
XDA-2017
XDA-2017YP
XDA-2017YP2
XDA-2017T0
XDA-2017T2
XDA-2017T10
Assuming that you will continually update and/or customize your phone. You will probably just memorize this, along with other important information. Some important things you should include while researching is as follows (the top two are very important)
1. [Model Number] ex) XDA-2017T1
2. [Android Version] ex) 6.0.1 Marshmallow
3. [Baseband]
4. [Kernel]
5. [Chipset]
6. Is device "rooted?"
7. Is the bootloader unlocked?
8. GSM or CDMA. Older devices even use IDEN
Those are only some.
* I also want you to know that im not trying to lecture you, or give you a hard time. I am honestly trying to help you and in order to successfully help you I have to ensure that you know things, or mention things, that is important to do. So your device isnt broken, or you get information that is correct but incorrect for your specific device.
But back to the topic originally referenced.
Q) "Is the program Dr. Fone able to bypass the screen lock security measures on the Samsung Galaxy S7?"
A) Based on limited information that is device specific, and the current Supported Devices section from Dr Fones documentation
"No"
• Dr. Fone doesnt have the capabilty to bypass your screen lock. They will probably include the S7 within a period of time due to it being a main stream phone though.
• Remember this; locks can and will be broken. Just because a vulnerabilty hasnt been exposed or discovered doesnt mean that its 100% secure.
• Keep current with OTA updates, keep in tune with tech type news.
• Encryption is vast subject, but I can refer to it like the "invisible magical ink" That was popular in the 90's. The light that reveals the ink to the naked eye, is your password. The inabilty to see the ink normally without a specific tool, would be encryption. So if someone cracked your password, your encryption would also be disabled. I linked more information below, for you to read. I still dont fully understand encryption myself, nor do I believe or trust it.
I based this information assuming your device is the SM-G930. It is accurate as possible but not guaranteed. Do realize with the information I mentioned and with the question you asked. I was able to do a simple Google search and almost immediately found the answers. Try to figure things out before you ask in the future. You can repeat the process of not researching prior to posting but typically your post will die. If you get stuck and have put forth honest effort, the great people here at XDA will probably help out greatly. I hope I have helped you, and you now feel better about your concerns. please pay it foward.
If you feel ive helped or gave a honest attempt to help. Hit the thumbs up, that is the thanks button.

I'm sorry, I completely forgot to mention the model of my S7, it is the SM-G930F on Android 6.0.1 Marshmallow, thanks for answering me.
On the other hand, I'm disappointed that a commercial program can unlock a phone.
I hope that this way of circumventing the locking of smartphones will be solved, because malicious people could use it to unlock phones that do not belong to them ...
The only way to protect yourself from this program is to install an application that protects personal data.
Thank you again for answering!
Wondershare Dr. Fonefor unlooking thr screen.
Wondershare Dr. Fone is a powerful instrument to regain iPhone lost information, it can help scan and recover them from iTunes or iCloud copies in case you've got backup your iPhone into iTunes or iCloud, or it helps you regain contacts directly from the device. Besides it's harmonious with iPhone 5s/5c/4S/ / 4/3GS and it might recover 18 kinds of content such as pictures, videos, contacts, messages, notes, and phone log, voicemail, voice memos, calendars, reminders, etc.. :good:
I agree with you. A commercial program available for a few dollars can unlock a password protected phone. What is Android/ios waiting to solve this threat?

Best option for anonymous telegram usage

Hey guys,
before you start with: Telegram is ****, better use "xy app", i need to use Telegram. Period.
With that said, i come to the main Issue: Whats the best Option to stay anonymous while using Telegram?
I Have an anonymous sim card already to verify the account.
The Important issue is: i Don't want anyone in my group to be able to link my telegram to my real identity.
I have a few options to look at, want to learn as much as possible about the backgrounds and maybe find a solution with your help
I just throw my questions here, feel free to answer a few of them.
1. I have 2 Android phones to choose:
a) Huawei p30 lite
b) Moto g(7) power
Which one would be better for my operation and why ?
2. My plan is to use Orbot with the VPN option so theoretically all my traffic should go through tor only. How safe is that ? What can i do to make that maximum safe?
3. Is it generally better to go with rooting & custom roms or staying with the stock rom and modify it for maximum anonymity?
4. What would you do if you would like to use telegram fully anonymous ?
5. Is it generally better to go with a sim card or wlan only ?
I hope i will learn something from you guys,
thanks for reading
Cheers
The Important issue is: i Don't want anyone in my group to be able to link my telegram to my real identity.

If the only thing you want to do is prevent people in a group from knowing who you are, as the above quote suggests, then it's quite simple. Since you say you already have an anonymous sim card (I'm guessing you are refering to a secondary sim card and phone number that noone knows belongs to you, not some untraceable futuristic 007 style gadget that I don't believe really exists) just change your name and username in the settings and off you go.

thank you very much for your answer. Let me think about this if I am right: So you say I am already safe from people linking my identity on telegram.
it’s right, I use a SIM card which is not linked to my identity but not 007 anonymous hehe basically it was just a virtual sim to activate telegram and it’s gone now. I am in my wlan for connectivity that’s why I have an up Adresse that could be assisted to my real identity and I think users on telegram with somebasic k owl edge could easily get my up adress, at least If they got admin access in my group and can get my telegram Id.
And even if that’s not possible, at least it’s possible and logged on some telegram servers where nobody knows what’s exactly happening with that data so it’s not considered safe to spam my real ip adress there and users could theoretically buy this data from the telegram devs.
So I still need to mask my ip adress to use telegram and my current approach is orbot as vpn.
Is there any way you can think off where my ip would be leaked in this process ? I am running orbot permanently.
Cheers
