Ratings and reviews

Good. Private. Secure. It used to send photos and files without altering their format or resolution. It now does lower the resolution and quality. However, it was updated so that it can be muted for 8 hours to silence at while sleeping or at work. Some of the new options are irritating. I now have to scroll to select all because of options like strikethrough. It's also irritating that when I pull down to refresh, it takes me to an empty page of no chats.

App is causing my share menu to crash. After last update, whenever I try to share something on my phone( not even using the signal app) the share menu crashes. I had to one by one disable different apps to see which one was causing it. And it was this one. I disabled Signal, and I can now share images, links etc again. Found other users online having the same problem. Hoping you see this review and a quick fix.

Update: Cannot delete contacts! Refreshing does not recognize when one was deleted by phone. No easy way to know which media is saved to phone and which isn't. I've also requested the important feature of being able to edit and star messages and pin them in groups like in Telegram. Would love a small notepad for each contact too but overall great.

What's new

★ Chats now open much more quickly, so any conversation about where you're meeting friends for dinner will always sort of be about fast food.
