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.

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.

I got this to get away from iMessage when moving to android, and to get rid of the file size limits on mms and the degradation of quality. It has some getting used to but it works well. The video and audio calling is a little buggy, but that may be because of ios to android or something. No ads means this is a 5 star for me.

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.
