Hi All,
I am new here, so sorry if I mess up something or don't know things obvious to most of you .
I am digging through many articles/review telling about mobile OSes, but can you tell me which one gives me most privacy and security?
What I mean by privacy?
First of all I do not want that any of my data is sent to any central server of some big company like Google/Apple/M$. I don't need synchronization.
I can live without gapps and fb .
I don't want to share my contacts, and don't want anyone to read my sms etc. so encryption would by nice.
By security I mean that I can restrict apps what they have access to.
So definitely open source os without any "under the hood" soft like "we know better what you need".
I was testing few OSes on my Nexus 4 and my current summary is like:
- Stock android gives a lot of information to Google through gapps, so I don't want that
- Cyanogenmod - I heard about some rumors of closing some part, using proprietary libraries and in privacy policy I see that they also collect quite a lot of data. Big plus - Privacy control for apps.
- Ubuntu touch - although I like the feel it seems that Canonical is also collecting tons of data and when I was supposed to register while installing any free app from the market...?
- Omnirom - is considered to be open-cm - what you say? Is it almost the same? Does it control app permisions?
- Firefox OS - for me it looks most promising, they write on their webpage that every app has an access only to the part of disk dedicated to it (if I understand android policy "Access to SD card pemission" gives any app right to read/write anything on whole SD?). Also they explicitly say what they collect, the give possibility not to send reports etc.
So what you say?
I was considering Omnirom with F-Droid, K9-mail, Text Secure etc. OR Firefox OS. Any better options?
Thanks a lot for help!
Hi,
I'm looking to get a secured space where I can launch some android apps with my personal data.
That a way I can separate personal data of work data.
I know samsung provide "knox" which is the best solution, but it's not working in others brand device.
Earlier, I had on my Nexus tab, the possibility to use an owner account and to swype to an "guess" account which can also a solution,
but it seems to not be available on recent release of android.
So anyone can give me some solution availabe ?
Cheers?

Which version of Android are you using? I have android n stock and there is the user option if you go to the settings app, there you can find the guest option and other options as well.
Well, I didn't find it on android 6 on my Xperia M4 Aqua.
On my Samsung S6, there're android 7, after many research I dind't find it. This phone is a very good device with knox but after a falling ugrade
the knox count rise to 1, so knox saw that as a security issue and it can't still running on.
So are are you sure it's always remains on android 6 and 7 ?
Hi,
I've recently tested user profiles on android devices (samsung galaxy tab a android 8.1 and xiaomi mi a1 android 9) and they seem very hard walled from each other, yet the switching between them is surprisingly fast and easy. Now my question, could they be useful to isolate untrusted apps from the main profile that's linked to my online accounts? With untrusted I mean generally harmless but nosy apps from the play store (with a blank google account ofc).
Thanks in advance for your answers!
Hey guys,
what do you think about GrapheneOS? (https://grapheneos.org)
I think there are some disadvantages:
- only Pixel devices (because only these have some security "flags")
- no root access
- hardcoded Google domains
and some advantages:
- good hardware support
- hardenized aosp
- closed bootloader after flashing
Now I would like to discus about this ROM
I too would be interested to hear about anyones experience regarding this OS

I'm interested in this ROM too. I have a Pixel 3a. I haven't flashed it yet because I'm trying to find out what people's experiences are first. There doesn't seem to be a lot of posts about it. Did you ever flash it? Also, what do you mean by "hardcoded Google domains"?
Well, the captiveportal contacts the Google servers regularly when you connect to a WiFi. That was one reason why I lost interest in the ROM. The other was the limited device support and missing root access. I absolutely need access to the iptables. As a one-man show, the ROM can be adjusted at any time.

Do you have some kind of reference for that? I'm using it now and would really like some proof to bring up in their subreddit as a WTF.
graphene seems great, no root does not
I don't want the bootloader locked.
I want Magisk extensions
I need root for LP _only_ to remove ads. Is there something like LP that allows (interactively) disabling app activities?
hardcoded google domains info from faq
https://grapheneos.org/faq#device-support
GrapheneOS leaves these set to the standard four URLs to blend into the crowd of billions of other Android devices with and without Google Mobile Services performing the same empty GET requests. For privacy reasons, it isn't desirable to stand out from the crowd and changing these URLs or even disabling the feature will likely reduce your privacy by giving your device a more unique fingerprint. GrapheneOS aims to appear like any other common mobile device on the network.
HTTPS: https://www.google.com/generate_204
HTTP: http://connectivitycheck.gstatic.com/generate_204

Thanks, right from there
I have Graphene OS taimen-factory-2020.07.06.20.zip on my Pixel 2 XL.Under "System update settings" is "Check for updates" but nothing happens if I tap.Only the field becomes darker.Has someone experience with this?
Update with adb sideloading to 2020.08.03.22 works.
OTA update from 2020.08.03.22 to 2020.08.07.01 likewise.
I'm personally not a fan of these kinds of projects, they aren't really all that 'secure', you're still using proprietary vendor blobs and such
help please
Hello! In the description
I pointed out that you can change servers just not through the GUI.
Has anyone tried this?
```
Providing a toggle in the Settings app for using connectivitycheck.grapheneos.org as an alternative is planned. The option to blend into the crowd with the standard URLs is important and must remain supported for people who need to be able to blend in rather than getting the nice feeling that comes from using GrapheneOS servers. It's possible to use connectivitycheck.grapheneos.org already, but not via the GUI.

captive portal leak + location services data leak
Few points:
1. General idea is that privacy/security oriented OS (as graphene is advertised) should limit network activity as much as possible, and not ping google using captive portal service every few seconds providing perfect IP-based location to google
It is possible to switch it off, but should be off by default
2. Connections of android location services to get GPS constellations were shown before to send sim card imsi and connected cellular tower id to provider (qualcom/google):
"blog.wirelessmoves.com/2014/08/supl-reveals-my-identity-and-location-to-google.html"
Graphene still allows those connections (check their FAQ on website)
W/O root no way to switch this off. Even some devices ignore config files and still leak data (on the level of cellular modem most probably)
3. Android services make other weird connections. Example: AOSP dialler app is querying phone numbers against online database leaking all contacts to google. How was this taken care of in graphene? Are all AOSP services/apps security-verified to not leak any data?
w/o root no way to install afwall to block everything
Is graphene built-in firewall capable of blocking system services from network access?
Hello folks,
My 12 YO would like to have a device of his own. Since the school is a hybrid, his request is getting consideration, for various reasons. I am going to hand over rooted OG Pixel XL with Lineage OS to him.
While I trust how my 12 YO would use the device, I still would like to keep everything in check to be absolutely certain. According to fellow parents, this is the age things can go out of hand pretty quickly. I would like to enable the following constraints. He has agreed to the constraints. I do not have Tasker but I have purchased MacroDroid.
- I would like to know which apps he uses and how long. I am esp. worried about the extensive use of YouTube.
- He is barred from social media completely but I would still like to prevent him from installing any apps without my permission.
- I would like to create a profile that he will be able to use only specific apps during school hours (so no games during school hours).
- I would like to have a constant location of the device.
- I would like an app that would take random screenshots.
- Is there any app with a one-time fee that will do all of the above (no subscription model).
- Those parents who have been through this phase, do you have any other suggestions?
Thank you for all suggestions.
(P.S. - Pls do not comment on the thread if your answer is, you should not give the phone to your child for whatever reason.)
