Integrated firewall? - Samsung Galaxy S21 Questions

Hi everyone,
right now I used adGuard since it works both as an ADblocker and as firewall. If possible I would rather switch to Blokada since it's open source.
The issue is that Blokada doesn't have a firewall that can block internet access to some app.
Does Samsung have an integrated firewall that I can use? I can't root the phone so I won't be able to use a custom rom or something like that :/

Best Firewall?

Hi,
I am looking for a firewall that would allow me to control which application can connect to the internet. After making some search, I've found these :
1. DroidWall
2.WhisperMonitor
3.AndFire
Since my device is not rooted, Droidwall is not useful. Have anyone tried Whispermonitor and AndFire? Which is the most useful firewall between the two or do you know another app?
Thanks!

[Q] One-Click VPN enable widget

Does anyone know a widget that can one-click enable a configured VPN? All widgets I can find only enable VPN's configured in the program itself instead of the VPN's configured on the system, usually those applications also don't support OpenVPN.
The closest I can find (on CM7.1 and the market) is adding a settings-widget that opens the VPN settings. This allready reduces the amount of clicks to two.
Is it technically even possible to make a widget for this?
this app
maybe help you quickvpn (market search)
QuickVPN does not have a one-click widget for my homescreen and doesn't use the internal VPN settings.
Have you tried "1 VPN"?
https://market.android.com/details?id=com.doenter.onevpn
1-VPN is the same story... It uses it's own sources for VPN rather then the android VPN settings.
It isn't possible using the Android SDK, but some manufacturers expose it using their own SDKs (according to this).
It's something I'd like to support with Awesome Widgets, but it might be hard to support all phones satisfactorily. I guess a fallback would be to show the settings if it wasn't possible with a particular phone
All the best,
Ash
Wouldn't it be less of an issue when using a custom rom? (I use CM7.1 on my Desire Z)
Yeah, if you have root access it's probably not too difficult (with a bit of java reflection), but I don't think the majority of users will know anything about custom roms or root access.
They'll feel conned when it doesn't work on their standard device, something I'd like to avoid
I think quick vpn client can help you in this. or else you can check android market for some sort of widgets. I haven't tried it but i am looking to get best paid vpn service and free vpn service for htc chacha...?

vpn and adblock

On non rooted Android, is there any way to use a vpn app and the adblocks using dummy vpn like block this, adguard, netguard at the same time?

Sorry I didn't specified clearly. I meant to say adblock that blocks in app ads and a real vpn app at the same time.

Sorry for posting in this old story again, but I have the same question and I don't think it is answered now.
I typically use AdGuard on my non-rooted device. But if I connect to a public WIFI without (individual) password, I would like to have a 'real' vpn app, that encrypts my data. This VPN of course disables AdGuard, so I have no ad blocking anymore.
My question are:
Is there a 'real' VPN that
a) additionally blocks ads
b) automatically connects to unsecure WIFI (e.g. it doesn't need to connect to my home Wifi)
Thanks a lot,
W

a) Private Internet Access has such an option (called PIA MACE). I do not know how efficient it is, though.
b) I don't know. PIA does not have such an option. Perhaps this could be solved using Tasker.

VPN-based adblockers not working

Hello there,
it seems that on the S9+ (and maybe S9, tho users over there report everything is fine) all the VPN-based ad blockers like DNS66, Blokada and the likes do not work correctly. When switching between wifi and mobile, the connection randomly dies, not letting anything through anymore until you restart the phone, or disable the blocker. It is documented in a github issue for DNS66 here. This is annoying, as I found this solution the most user-friendly. I know there is Adhell 3, but a) it's annoying to resign and reinstall every 3 months and apply for new keys and b) it doesn't block everything, not even if I manually feed it with all the hosts files that DNS66 uses. It blocks ads alright, but misses quite some.
Is there any known fix for this, or any other adblock suggestion besides that? I know that rooting and adaway would be best, but I won't root anymore since Samsung here in Europe straight off denies any warranty requests for rooted devices, even if it's got nothing to do with the root itself.
Adguard would a suggestion, but it does use a VPN blocking service for system wide blocking. It's not free and is subscription based. At one time I used adguard over dns66 as adguard worked and dns66 did not (VPN issues with dns66).
For non rooted users there is really no other options. Unless you want to setup a pihole server, somehow get your dns setting on your phone to point to the pihole server and go that route. In the case of dns changes on non-rooted devices it's either a VPN based change or knox. So your options are limited to one or the other. Of course this becomes moot if your plan on only blocking ads when you use a wifi connection.
I've done the pihole route before too, it works but doesn't catch everything. Some ads originate from the same domain as where your visiting, in which case dns adblocking won't work. For those scenarios cosmetic filtering would.
Otherwise I use adhell3 and adblock plus plugin on samsung browser. For practical intents and purposes I steered clear of VPN based setups for a reason. Also I don't mind recompilimg adhell3 once in a while, he's really put a lot of work into making it as simple as possible. I've got my android studio setup so that I just pull the latest changes, build the apk and install.
If adhell3 isn't your cup of tea then the only app I know is Disconnect Pro which costs $24.99 in the galaxy app store. Disconnect Pro functions the same way as Adhell3 does.. as a front end configuration for knox. I've read somewhere that Adhell3 has more features then Disconnect Pro, but I didn't look to much into that to find out what one has over the other.
If I were to suggest something I would suggest adhell3 combined with adblock plus plugin for your browser. combined those work the best for me... some ads might slip through, but dns based ad blocking is not the same as cosmetic ad blocking. Adguard should still do cosmetic filtering, but it's been a while since I used that app.
I am use this one on my S9+, it's free and work fine.

Question Ad blockers

first time posting on the P6 forum (last had a P3).
previously, I used dns.adguard.com for the Private DNS setting. however, that was not blocking all of the ads from within some apps. it worked pretty well until then. Now, I downloaded blokada 5, and that successfully blocks almost all ads. the lone problem is that when connecting to a website, it often slows it down.
curious to see if anyone has a similar experience or recommend an alternative to dns.adguard.com.
thanks!

I personally use both NordVPN as well as AdAway with root; AdAway has a VPN function of its own, and you can use your own host lists, but the VPN solution is more resource intensive than the root solution.

interesting - thanks for the quick reply.
i do have windscribe, but rarely use it. i have not rooted this device yet, as my understanding rooting will disable Google Wallet/GPay - and I use those more often than I would need to hide ads.
+1 to AdAway, plus if your preferred browser supports it, install an adblocker in it as well - I use uBlock for Firefox.
There's also MinMinGuard which has recently gotten an update to make it work on current systems, but that requires Lsposed if you don't already use it, as well as individually enabling it for every new app you install. Honestly, though, with AdAway plus a browser adblocker, I almost never see any ads in any app, so I don't find MinMinGuard necessary anymore.
Ad blocking apps like Blokada and DNS-based ad blockers like AdGuard can be effective at blocking ads, but they can also slow down your browsing experience. This is because ad blockers need to process and filter out ads, which can take up resources and cause delays.
One alternative to dns.adguard.com that you could try is Cloudflare's 1.1.1.1. This is a free, fast, and secure DNS resolver that also includes ad-blocking capabilities. Cloudflare's 1.1.1.1 uses their own ad-blocking technology which is based on the same technology used by their enterprise-grade Web Application Firewall (WAF). This can block ads at the DNS level, which can be less resource-intensive than using an app like Blokada.

No root will not disable Google Wallet/GPay, you just have to install Safety net fix module and all works great, for banking apps just hide root into settings. I use all my banking apps, card tokens and gpay/wallet everyday. Rooking root + adaway.

i tried installing the 1.1.1.1 app from cloudflare, and it did NOT block the ads on my scrabble app. thx for the suggestion though.
Have you tried using a browser like Brave which would help with your browsing experience. I use a combination of Blockada for system wide blocking, pihole for in-home network based blocking and browsers like Brave/DDG for blocking and so on. I have a tasker based activity for turning on/off blockada when in home/out of home. It's my non-root solution.
Additionally you can also lookup -
ahadns.com - you get a customised secure dns url, you can setup filter lists and the URL is configured based on the seelctions.
nextdns.io - something similar to the above. 300,000 free ad-blocking queries per month and past that, the non-blocking DNS service will work till the next month.

Hey, just stumbled across your post and thought that if you use piehole at home, you should be able to just use a VPN to you piehole when on the road so you don't have to rely on third party apps. Don't know about performance though, but you might give it a try.
Cheers
Been taking NextDNS for a test ride. Easy set up with a lot of features, up to 300,000 queries per month for free. What's not to like?
Fast and running pretty smooth so far, day 7.
