Calling is not stable When my data or Wi-Fi are turned on, the call automatically drops. Sometimes it doesn't ring and when you look at the conversation, you can see someone called.
It won't complete calls I wish it would let me make calls when my phone is off like I'll call my friend and it will say connecting and we both hear the right be when we try to answer it won't go through and I only use it cause my phone is off right now.
I have automatic updates turned off! It automatically updated! WTF I don't like anything updating until it has been out for awhile because there always seems to be issues.... WTF messanger, I have auto update turned off in Google Play and it just updated
Resource and battery hog The messenger app and it's brother the 'Facebook' app are both resource hogs. They make the phone upto 40% slower and drain the battery. There were several articles written about this on several reputable sites. All in all both the Facebook and it's messenger app deserve at the most two-stars.
Messanger Something we write and change our minds and no way to delete that one little chapter you would like to delete. Will that happen someday without deleting out what I have chatted for weeks.
saves battery life by installing FB Messenger while uninstalling the Facebook apps (yes, it can survive without the FB apps), I was able to save 20% of battery power.
