I have a samsung galaxy j3 pop from boost and my husband has an lg flip phone from at&t. His google acct is open on my phone because he uses it for internet often. I see in his activity com.samsung.android.messages and com.samsung.android.incallui quite often and its times when i neither sent nor recieved messages and no calls either. And i assume nothing being done on his lg would appear as a samsung app. And theres none of our old samsung phones still on his google acct. What is this activity from?
