Hello.

First, thanks to the developer(s) for such great app. It makes our devices a little safer.

Here is the problem: I have been using the Google Play version of the app for several months without problem (under Android Lollipop).

Today, I updated my Nexus 6 to Mashmallow, and when I have any of the two main switches of the app enabled and the app is not in the foreground, my device disconnects from WiFi. In Android WiFi settings, it says "Authentication error". When I disable the two switches or the app is in the foreground, the device correctly connects to my WiFi network. I am using my home WiFi network, which is on the list of allowed hotspots.

Do you have any reports of the app failing on Marshmallow?

Please, tell me if you want more info.

Good evening @BramBonne, I've been a long-term user of your wonderfull app and now wonder why it suddenly needs limited location access after the latest release. I would like to keep my GPS turned off and not be nagged all the time that the app may not function correctly without having revealed my location.

Since upgrading to Android 5.1 (from 4.4, via CyanogenMod 12.1), I have found that my Nexus 5 will not reconnect to the known Wi-Fi when returning into range. The status is, "Wi-Fi connection failure". I must turn Wi-Fi off and then on again to successfully connect. This was working on Android 4.4. I have tested with and without the app installed several times to confirm that the app is causing it.

Hi Bram, First of all, congrats for your Wi-Fi Privacy Police Android app!

I think it would be very interesting to add granular management capabilities for the access points (APs) registered by the "Data protection" feature. Instead of just having a single "Clear allowed and blocked hotspots" option, I would provide an advanced option (replacing the current one, or simply complementing it for advanced users) to be able to manage each trusted (or untrusted) entry individually.

The suggested new option should allow the user to get access (view) the current list of trusted/untrusted APs (including at least the network name (SSID) and all the associated MAC addresses (BSSIDs: 1-N)), and also provide edit capabilities, at least to be able to simply delete one of the entries individually (instead of them all, as it works currently). By entry I mean a single association between a SSID and a BSSID, as there can be multiple BSSIDs pointing to the same SSID.

This would allow users to have visibility on the current list of trusted/untrusted APs, and also allow them to clean it up easily, for example, when an single AP is replaced at home or at the office.

Cheers, Raul

Hello. I have tried your app, but I still see probe requests in monitor mode. You need to change wpa_supplicant settings, to do it you need to modify a component which is used to connect to hotspots which creates settings file and starts wpa_supplicant. This probably can be done using xposed. Also could you add mac addr randomisation and displaying into it?

As per mail from Denilson Sá:

• There is a free WiFi called "X". This is the Wi-Fi that I've saved and that I want to connect.
• There is also "Y", which is provided by a phone operator here. I don't want to connect to it. But I admit that someday in the past I had connected to it.
• I've already selected "forget" at the Android settings, I've also cleared known hot spots (for that Wi-Fi name) in your app; still I get the question "Are you sure network 'Y' should be available right now?"

As of today, this app blocks traffic from additional android users, which might not have installed the app. The rules should only apply to the current user, since this behavior causes network failures for all other users on the device.

"Known hotspots" only shows hotspots it knows about, or has seen. It doesn't show which ones are blocked and which are trusted though.

Suggested: green blob next to name of trusted MAC address, red next to blocked. And then some combination of the colours on the SSID level.

Currently when I leave my home and so a trusted hotspot, WiFi stays enabled this is the correct behavior? WiFi should be disabled automatically IMO.

I'm on Samsung Galaxy S2, running on CyanogenMod 12.1.

As proposed in an e-mail by Denilson Sá:

An airport is a large location, thus it is covered by several access points with the same name. It is also a place where people walk around a lot. This means that I walk 10m and I get a question from your app and the Wi-Fi disconnects.

A solution for this could be an option/button/whatever that let's the user say "auto-add all hot spots with the same name for the next hour". Since the user will be around for quite some time, and for sure it will hop from one access point to another (but with the same name), it makes sense to let the app consider all of them as valid ones. The same UX can be applied whenever there is a large area, such as in a Mall.

(of course, the time of "1 hour" could be selected by the user, but I know making the time adjustable makes the interface harder to design)

If i connect to a new network, i got the popup if i want allow it, but the connection isnt blocked. Yes, i allow and enable GPS.

How can i verify that the other features still work?

The original text color of the component is '#656D5C', and the contrast between the text color ('#656D5C') and the background color ('#DCEDC8') does not meet the standard of WCAG 2.1. In other words, this color cannot be easily seen by everyone. So, to solve this problem, our team designed a tool that can automatically detect and repair such problems. The test report and recommended replacement colors ('#646464') are as follows:

The figure on the left is the original page, the figure on the right is the repaired page, and the figure below is the problem detection report. If you think it is useful, please give me feedback. Your feedback is very important to me. We sincerely hope to receive your suggestions and opinions as an app developer.

I suspect this happens because in my Android settings > location > advanced > I disabled 'locationnaccuracy by Google'. This is a setting which directly relates to access point scanning.

I can't tell if wifi privacy policy is working or not or if I even benefit from this app while I have my phone configured not to use wifi based location accuracy. Either way the request for the location permission is confusing, since it is already granted.

I am using Android 10 on a Motorola Moto G7 Plus

The README lists as one of the reasons to use this app:

It prevents your smartphone from sending out the names of Wi-Fi networks it wants to connect to over the air. This makes sure that other people in your surroundings can not see the networks you've connected to, and the places you've visited

However, AFAICS this no longer appears to be the case even without this app installed: I haven't been able to reproduce this issue with my Android 9 device. Do we know until what Android version this was a problem?

I've used your app for quite some time now, and I'm sure I've used it on my Pixel with Android 8.0 in the past without issues, though this would have been up to ~mid September 2017

Unfortunately the recent OTA update for the OnePlus 5 has a significant battery drain issue when this app is installed.

Model: ONEPLUS A5000 OxygenOS: v5.0.1 Android: v8.0.0 App: v2.2.4 (from Play)

The screenshot below covers an 8-hour period where I installed and removed the app every so often. As you can see the "Awake" bar is solid when the app is installed, and significantly more empty when the app is not installed, additionally the battery discharge curve is significantly steeper with the app installed... which is what drew my attention to the problem in the first place (significantly shorter battery life).

I would be happy to collect more data if you like, though I'm afraid I'll need guiding.

Connceting to an AP the first time works fine. but reconnecting or connecting to other network is broken. You can see android trying to rescan for network very agressively. The only workaround is to forget existing networks and restart android before it is possible to reconnect.

If you need any logcat dumps I can make one.
