Same here. I bought the Ring Doorbell 2 with high expectations which it met. But the speaker volume is truly laughable. I now use the Ring Pro Doorbell instead of the Ring 2 and it seems to be a little better but I'd love to switch back to the wireless option.
If you have a Samsung, this may help. Disable the Event History Time Line in New Features menu, then uninstall the app, then reinstall the app. This may help, it certainly does with S9 and S10 phones.
(They have known about this for 4 months and still done nothing about it!)
Just bought a Ring Doorbell 2 this weekend and installed it a few hours ago. I do like the product and video, but like others, I feel the speaker quality is very disappointing. When testing with my wife, I can hear her pretty good on the phone end, but for her (the person outside at the doorbell) it wasn't great. Audio seemed to cut out a bit (I have strong wi-fi at the doorbell) and even when audio transmission was smooth it was still very quiet. I do love the camera so far and would just love to see an audio fix. Thanks!
Phones tested were Samsang Galaxy S8 and S9+.
I have the SAME issue. This is so frustrating , i can hear the person ringing the doorbell fine but they cannot hear me. RING please fix this!!!!!
