Affected app version

1.5.1

Affected Android/Custom ROM version

14

Affected device model

Fairphone 5

How did you install the app?

Google Play Store

Steps to reproduce the bug

1. Install app
2. Try to have someone call me
3. See bug: No call ever gets patched through. (This isn't the same thing as "i can hear a call but can't accept it." Calls go straight to voice mail, without ringing a single time)

Expected behavior

A notification/full screen option to pick up should appear.

Actual behavior

• The caller doesn't hear the call ringing but immediately is directed to voice mail, as if I had immediately hung up or had no service
• I only get an SMS after the fact, telling me I had been called.

Screenshots/Screen recordings

No response

Additional information

• I have a dual-SIM setup. Calling the first (physical) SIM fails, as described above. Calling the second (e)SIM works as expected.
• The issue persists even when disabling the second (e)SIM.
• The app has all permissions enabled and is allowed to run in the background, ect.
• Other phone apps such as the "Amadz" phone dialer or the default phone app (from google) are able to patch through calls to SIM1. Only Fossify Phone (and the Simpletools-Phone app) fails.
• Reinstalling / deleting all data / rebooting the phone / going to flight-mode / resetting network connections doesn't help.

I have the same setup (Fairphone 5 with physical SIM and e-SIM, the same app version), but I don't have the issue. The only difference is that I have installed the Phone app via F-Droid.

What network operator is your physical SIM using? Could it be an operator related setting?

EDIT: Ignore my question - it wouldn't work with other apps as you have mentioned.

Yep, that's why I decided to post this bug, since receiving calls seems to be working perfectly fine with other apps.

That being said, during the last few days, I noticed that "Right Dialer" – an app also based on Simple Phone – also seems to be having this issue. On the other hand, the default (google) phone app and a fairly basic open source phone dialer app called "Amadz" seem to be working perfectly fine.

I suspect the bug consists of something all these Simple-Phone-based apps have in common, making them different from other alternatives.

@Glitchy-Tozier

• Do you have Block calls from unknown/hidden numbers enabled? Does the issue go away if you disable it?
• Do you use pattern blocking? If yes, please check if there's any wide-ranging pattern like +*. Currently, blocked numbers and patterns are stored in the system, so they survive reinstallations.

This seems like a bug in the call screening service.

[Glitchy-Tozier]

@naveensingh I don't block any numbers, and I don't even use a call-screening service on my device.

Out of curiosity, what happens if you disable voicemail?
