New Samsung apps in the marketplace

Several new apps showed up in the Samsung Zone last night:
Video Call
Basically what it sounds like, a 3G-based video calling app. Unfortunately, it apparently requires a FFC, so all it does on the Focus is display an error message and quit.
RSS Times
A pretty nice Google Reader app
AllShare
Samsung's DLNA media sharing app. But again, on the Focus all it does is display a "not supported" error and quit.
FunShot
An interesting-looking (haven't played with it yet) photo editor with some "funky" effects.
MiniDiary
A diary app with text, voice, drawing and photo support.

I'd have thought OEMs would be allowed to only target certain devices for their apps, so either they can't and theyre for the omnia w (etc) or we might be inline for some driver updates...

I use Minidiary which is a good app... we cannot use vedio call app but i think its prety amazing specially cos we can make vedio calls to iphone and android phones even if they dont have this app...
i want to upgrade to omnia W phone, but i will loose all my texts and have to unlock all levels again from begining in my xbox games.. which is the only thing preventing me from switching phones..

There is also an Advanced Text Message app if you tap on "more from Samsung.." but it doesn't work either.

They should let the video call app work on phones with no ffc. At least we can see the other person or we might use a mirror.
Working dlna would have been very good.

I can't see that one on my Focus, but I do see the new high fidelity positioning app, which is the first new app from Samsung that installs into the settings screen. It has two settings, one that increases GPS accuracy by using other sensors such as accelerometer and compass, and one that enables use of GLONASS (for users in Russia).

I downloaded that app. Interesting how it installs itself in your settings. My question is, what if we want to uninstall it? How do we? Holding it down doesnt give us the option.

if you can sideload the xap this worked for me.
get XAPDeployX.exe
load Zune and have phone plugged into USB
start XAPDeployX.exe
load the app you want to remove from settings page
check options "force uninstall if application is already installed"
click deploy. at some point XAPDeployX will tell you that it found and successfully uninstalled the existing application.
right then you unplug the phone, just in time before it installs the new one.
voila, the app is gone from settings.

There is really no need to uninstall it. It takes up very little space, and if neither option is turned on, it does nothing.

Oh, I am. OCD is my life . I just look at it as Samsung providing an app to install a Mango setting that didn't make it through development in time for the official Mango update. In other words, if the setting had been part of the Mango firmware update, there would be no way to "uninstall" it without uninstalling Mango, right?
In fact, I wouldn't be surprised if the setting is automatically included in future Samsung firmware updates.

Location Services

Hello all!
First off. Long time IOS user that just purchased a GN. More specifically - I just came from an iPhone 4.
Love the GN.
I can't seem to figure something out. In IOS I can selectively set whether or not to allow location to be ascertained by apps individually. The only thing I found that I can do is turn off location services for everything. There's some things that I would rather leave on i.e. google maps etc.
Can you do that on an individual basis?
Other than that I'm digging Android. There are some things that are worse compared to IOS, but there are also some things that are executed better on Android.
Aloha!

It is possible if you are rooted. It requires that you revoke the gps permissions for the apps you don't want to have that access.
The problem is that this may cause the apps to force close if they can't get that access.

Well that sucks.
Not that I have to be rooted (I will eventually) but that it may cause the app to force close. That doesn't seem like an elegant solution.
I don't want to be visible (via location) to apps such as FaceBook etc.
I wonder if there is an opportunity for a developer to make some money providing this type of functionality. I may have to look at this to see how easy it is (or if even possible) to implement something like this.
Thank you for the response!

Yeah, per-app settings for location would be awesome for apps that don't explicitly offer an "off switch".
We can only hope this becomes a stock feature in the future...

Screen Overlay Detected

If this is in the wrong thread then please move to correct one.
Has anyone else had issues with this... I'll call it problem, but by the way it behaves, it seems more like its a bug.
It has only been something I've seen on Marshmallow. Try to install an app, and its 50/50 whether or not you get "screen overlay detected"
Try to give an app permission, "screen overlay detected".
I should also point out that it isnt just restricted to HTC. My partners (now apparently ticking time bomb) s7 has also had the issue
You can disable as many screen overlays as you like, it still doesnt go away.
I've noticed now, too, that anytime a chat head from facebook messenger is on screen when I try to do something like install an app, it will spit out that problem until I close the chat head. Which was never an issue, ever, before.
Where has this thing come from and why is it even a problem for Android?

Those chat heads on the messenger as well as light filters, as e.g. CF.lumen, are always screen overlays. Those overlays could read out the whole screen, and thus as well what you're typing into banking apps or similar. Thus Google updated the privacy policy of their devices in Marshmallow, ending up in this specific error message. Sometimes it's enough to just turn the screen overlay of via settings > apps, regarding Apps like FB Messenger, CF.lumen, and the like, on other times and Apps you got to reboot the device after done so, or disable the overlay within the Apps settings as well, and seldomly you got to uninstall such an App to get the problem sorted for the time being. At least that's what I could find out searching the web.

It's so malicious apps don't replace the install button with something else (like an install button to install something else).
It's quite clever if you think about it.

In theory I would say it's clever. In practice, it doesn't distinguish between safe apps that are harmless and those that aren't.

Since Facebook messenger (and pretty much all my apps, most of which don't even have screen overlays but are in the list for it) was downloaded from Google play, I would imagine it isn't difficult to implement a system that flags it as safe.
If an app is installed via an apk, even if it is safe, I would understand more the need for concern. You never know, etc.

It would be difficult to implement a system like that. You never know which app is fake or real. Maybe it was a modified version of the app, you'll never know.
Either way, the feature is there and if you want to install an app just quickly turn off your overlay. Not exactly a big problem.

What is the ultimate way to gain privacy on Samsung S20 Ultra (iPhone User Here)

Hello,
I have the Samsung S20 Ultra and I'm extremely impressed with it. However I'm paranoid about the integration with Google and the tele-metrics.
The phone is amazing and makes my iPhone 11 feel like 4 years old, the battery is better, the screen, it's fast - the first time I've considered switching full time.
What is the best way to improve privacy on this device?
Is there a way to install xLuaPrivacy, or it root needed?
Is there a custom ROM that has privacy features?
Is there a firewall I can use to control traffic out?
I'm a little out of date with the development world as I last had a Samsung Note 4.

There are private dns and VPN options built into the device (at least the unlocked ones), which you can point at any service you want, so you just need to find one that suits your specific needs or run your own at home (which you can do easily with even the cheapest Raspberry Pi and the free Pihole app). It's always best to use this method rather than local software - it's less resource intensive, doesn't require root, and gives you more assurance that things are working the way you think they are.

As above, pihole & dns.adguard.com

For maximum security, do not root the phone.
And put the apps you feel that require more security on secure folders. That's an extra layer of protection there. There is a dedicated chip for encryption and security on the s20 just for the purpose of security and privacy.
If u know what u are doing, you can even root the phone, miss out on knox and secure folders, but install other more interesting stuff like firewall to control what apps get to use internet.
For me, secure folders, vpn is good enough.
I love the extra privacy of the secure folders.. It has its own phone book, phone app.. It's like a second phone in there and not accessible from outside.
And you can hide many things in there Including apps. Just rmb to switch off notifications from the app in secure folders..
I have a wife that loves digging through my phone.. You can customize the secure folder name and icon. I even put it on my app drawer.
You can also freely move stuff in and out of secure folders.

If you want to get away from Google, then you need a Google-free phone. Something that runs LineageOS. Of course, installing LineageOS requires rooting, which also compromises security to a degree. So it is a trade-off. But if you are *really* paranoid about Google tracking you, then you need to get rid of everything Google, including Google Play Services. And the only way to do that is by using a phone without Google Play Services preinstalled.
xPrivacyLua requires Magisk, which requires unlocking the bootloader. If you have a Exynos model, then you can unlock the bootloader. If you have Snapdragon, then you can't. And any software firewall will require access to system files, which is impossible without root.

Agreed. I use Pi-hole at home, and dns.adguard.com as my default DNS. Both are very effective at blocking ads, but neither are comprehensive solutions for extremely privacy-focused individuals.

This is OT, but if your wife (or anyone else) is constantly snooping your phone, then there are obviously trust issues that should be addressed.

I use adguard + nordvpn + dns to block all ads and to control the Internet filtering better.
With ADB commands you can uninstall all bloatware and unnecessary stuff or disable them with package disabler Pro.
I'm on snapdragon and waiting for root release so I can use more privacy apps with magisk/xposed.

Disable blocklists one at a time until you can check firmware again, and you'll have the answer.

Odd, I've been using nextdns for over a month and on 2 June I was able to download & install ATE6 (the Australian releases are always slowwwww ...).
You can look at your nextdns logging to see what's being blocked when you try an update. The results are pretty much live; I used the logging to work out what was causing an app problem and whitelisted a few sites based on the blocked results in the log.

How do I get good battery life

Hi guys,
So around 1 month ago now, I got myself hands on a Note10+ (N975F)
I have been noticing screen off time drain, it is around 1.8% for me. I have tried using greenify, optimizing the settings, battery saving mode etc.
It hasn't really been working for me. Screen off time is really important for me, even more than screen on time.
So i wanted to know, how could I maximize the battery life of my Note10+? Is there like a custom rom you could recommend, like Lineage or dr ketan?
Knox is already tripped bcz of the previous owner, so that is no problem. Or a other custom rom or just with rooting something.
If you know anything, I would appreciate it if you could tell me,
Kind regards,
Crewz

First, you can select apps that you dont require to be always running, to be dormant, look for this option in settings, also you can install galaxy labs, there is a similar option there also, I disabled several apps via CCSWE, that have the undesirable behavior of being always running and accesing internet, such as facebook, chrome, youtube, operator apps, etc, also, with CCSWE you can deprive apps of certain undesired services that eat batt, this a process that takes some time, as you use the device, you can obseve and decide what to disable, to uninstall, or control via ccswe, I have my note 10+ since Sept 6 2019 and the battery lasts thru the whole day, I get some 7 hrs SOT on normal std use, when I play intensive games,, that is another diferent thing

Hey thank you for taking the time to help me. I have tried what you said, I went into settings and I went through my apps and selected those that don't need to run in the background. I also downloaded CCSWE from the playstore, i saw like 500 applications, but only disable or clear data from the application.
Are there any other device settings you recommend changing?
Thanks for your time.

Decide if you want to root it, if so you'll have many more options and tools to work with.
Otherwise get PD MDM to block apks from running at boot and disable them.
Use Samsung Device Manager and set to Optimized in main window. Toggle on fast charging but don't enable any other off the top 3 dot menu. You can then disable that app too. 3rd party power management apps including Samsung's can screw it up. Cloud apps, Goggle Backup Transport/Backup Framework are big offenders on my stock 10+
Disable Google, Samsung and any carrier feedback.
To hell with Bixby except Bixby Vision/Vision Framework which are needed by the cam for full functionality.
Play with it.

Don't disable Bixby Framework either.
The feedback options are buried in settings, you'll run into them.
I'm not rooted so I don't spend much time looking at what I could do. You do have real time cpu/power usage capabilities with it for weeding out the hogs... for one thing.

In the Goggle and Samsung account settings.
If it's a carrier phone one of the advanced network settings. Carrier phone; disable remote support, updates (unless you want an update), and all their software.
Keep Samsung account and apps related to Galaxy Store/Themes as you want to be able to download themes, icon packs and apps from there.
Excellent free icon packs... and the Good Lock family of apps.

Galaxy labs, Battery Tracker is useful.
See if Google Backup Transport or Framework are the culprits. If already package blocked clear their data and the data on Goggle Play Services ie gms.
It can be hard to ferret out as many apks simply are thrown together under Android Services.
Worse some Google apps falsely show under Transport etc even when its blocked. That why you clear the data of gms.
Use the factory load of Samsung Device Manager to globally clean caches. Reboots seldom help.
Turn off location, bt and wifi if not using.
Do not let Playstore run or Samsung updates unless your using them.
When running clean its ide current with screen on is typically in the 100-200 ma range. A few lower and higher. If you're getting a lot of spikes 400 ma and above at idle something is using a lot of the cpu resources...

So I installed Galaxy Labs and Battery Tracker.
I noticed that Google Foto's was on top with 7.1%.
Followed was whatsapp with 6.3%
And google play service was 3.78%
I haven't seen Google Backup Transport in the list.
Would there be like a way to turn off location automaticly when I am not using it, for example that it would only turn on for google maps or something?
Thanks for your time!
