One thing I have been wondering is why to use Whisperfish if the android app support works great with signal android app? Is it faster or more reliable?

Thank you for the insight!

Thank you so much for your insight! Definitely interesting to hear how it feels for new person. I have thoughts so that using the phone would feel very different from android/ios people are used to. But as you mentioned maybe not in bad way at all.

Have you experienced any hiccups or major bugs that have required deep debugging or booting the phone? What are your thoughts of the native browser? Have you been able to use maps like HereWeGo successfully?

Thank you so much for detailed answer and insight! I am definitely interested to try SailfishOS but would hope a little bit better HW compared to C2. Might still be that I try that one so I have feeling of the SailfishOS.

Extremely glad to hear that your wife has been able to use it as daily driver for so long

Definitely would love to hear your honest thoughts about it when you have tested it!
