Android 6 (and lower) compatibility

[schorschii]

Can someone confirm compatibility with Android 6 or lower? I don't have a real Android 6 device for testing, so I only can test it in the emulator. There it works on Android 7 an newer, but not on Android 6 or earlier.

Logging shows, that only content://<appid>/directories is called on Android 6, but not content://<appip>/phone_lookup/<number> for the actual contact query.

@alk99-abderrahman It works in the emulator (Android 11 & 12) but not on my recently upgraded Fairphone 3 (it worked on the same Fairphone with Android 10). Which smartphone are you using?

[alk99-abderrahman]

@schorschii thanks for the answer . i tried it with samsung A30s i added overlay and read contacts permissions but without result

Samsung phones generally cannot use this feature as they have their own phone app which is not implementing the CallDirectory lookup. A Samsung mod confirmed it in this forum thread.

thanks for the answer . i retried it on an other samsung a02 android 8 and it works perfectly (caller name + photo )even tho it have phone app.

Interesting! Some time ago I tested it with a Galaxy A22 (Android 11) but without success. Now, I would be really interested in decompiling the Samsung phone app but I don't have the A22 anymore. May I ask if you can send me the phone app .apk from your Samsung A02? You can get it as follows:

# 1. find the package name of the Samsung phone app - e.g. the Google phone app is called "com.android.phone"
adb shell pm list packages | grep phone

# 2. get apk path by package name (replace package name)
adb shell pm path com.android.phone

# 3. download apk from device (replace path by your own)
adb pull /system/priv-app/TeleService/TeleService.apk

So maybe there is a real issue in combination with Android 11 which some vendors don't have on the radar - but it is not completely broken: I installed Lineage 18.1 (Android 11) on a Google Pixel and there it works too (as in the emulator).

I also wrote this issue to Fairphone. I am curious to see what they answer.

i want to know the issue too . i used a third party app to backup the phone apk here are all apks related to the term phone https://file.io/iN9JSuBpfkjC

[schorschii]

Great, thanks. I'll have a look at it and get back to you next week.

Finally, I had time to take a look at the APKs. Unfortunately, they appear to be the wrong APKs. Can you please look again on your Samsung A02 with Android 8 searching for apps with "dialer" in it?

adb shell pm list packages | grep dialer

My recent results:

• Samsung Galaxy A22: specific dialer app without the necessary phone_lookup implementation (at least I couldn't find it with my decompiling skills)
• HTC U12+: own dialer app without the necessary phone_lookup implementation (at least I couldn't find it with my decompiling skills)
• Fairphone 3: uses the Google dialer app (default) with the necessary phone_lookup implementation, but stopped working after Android 11 update
  • I already contacted the Fairphone support and am now waiting for a response

As a workaround for Samsung, HTC and other devices, we are also able to install the Google Phone app from the Play store on those devices to get the caller ID working.
