Default Messaging App stopped working

Try popping out your sim and restarting your device then pop it back in. Also what carrier are you on?
If you are looking for a solid SMS app I would recommend Google messages. I know it's a Google app, but it's solid for SMS and RCS "if your carrier supports it" & if you set up Google Play services through the GOS app store.

Mine did the same. It seems the new android 15 and the messaging app are not compatible. I have tried everything except reinstall grapheneOS. I needed messages coming in so I opted for QKSMS app and seems to work very well.

Chucky Yep... I've been using QKSMS for over 12 months with no issues and after todays Alpha A15 update it is still working fine.

It's been over three years since the QKSMS app has received any updates. Additionally, F-Droid has archived the QKSMS app, as you can see here. However, there is an updated fork called QUIK SMS that aims to revive and continue the QKSMS project

Another open-source SMS app you may want to consider is Fossify SMS Messenger

I had to download it because the update is not compatible with messaging. I find I like QKsms even better

The Messaging app issue for me has been partially fixed for me. I can now receive a text message from a person as well as group chats but I still cannot send any messages using the Messaging app as well as QKSMS. I have not touched any settings outside of selecting QKSMS as my default SMS app. Any assistance would be greatly appreciated.

It is probable the issues are not related to Messaging client itself but likely to incorrect sms settings, relevant permissions not granted or other global settings affecting this.

ErnestThornhill

DeletedUser69 The fact that my issue was partially fixed by the updates that followed the initial Android 15 release suggests otherwise. If you think my issue is likely due to something else, what SMS setting, relevant permissions and/or global setting adjustments do you suggest?

DeletedUser69

ErnestThornhill I suggest nothing, everything worked for me without fail for nearly two years (and anything related to system apps). Look into your particular setup.

DeletedUser69 Very helpful. Thank you. 👍

Litmus9 Yeah. QUIK SMS is the one I tried and had issues with.
