Phone answered by itself?

Hey guys!

So, walking in to work this morning, I heard someone talking in my pocket. My phone had answered a call without ringing, put them on speaker and muted me on my end...all from my pocket.

What can I do to prevent this? I've got a pattern lock on already since I had previously found my phone trying to flag YouTube comments when I opened it. No fun having a phone with a mind of its own!

Thanks so much

Phone is locking itself on vibrate...

Ok so first I've had this issue on two phones and across three different roms so I'm not sure what if any app is causing the issue or if it's some hidden setting I've screwed up somewhere. It first started on my Nexus 5 when I was running Paranoid Android. I was having issues with that ROM and my weather app FCing so I switched over to catalyst. The issue would come up more when I switched over to catalyst. I thought maybe it was just an issue with the phone/ROM and I recently purchased the Moto X Pure. When I first got the phone I did a straight transfer of settings and things but the issue persisted on the new phone. So I did a factory reset, deleted EVERYTHING and started over. This time I manually added my google account and re-added all my apps from a backup. I made sure to exclude every app that might cause an issue (anything like automate, tasker, etc).

The problem is, seemingly randomly my phone will set itself to lock. For example my phone was on ring when I went to dinner, I put the phone in my purse, it was in ring when I got home (I got a facebook notification) and I set it on the table. I just picked it up to make a phone call and it was on vibrate, I never touched the phone. This happens randomly throughout the day, at home, away from home, there doesn't seem to be a pattern. IT can happen at night, it can happen in the morning or afternoon. When I try to turn the volume back up it doesn't let me. It will only let me change from vibrate to silent, and the different notification override settings, but I cannot turn the ringer back on. If I reboot the phone the ringer comes back just fine. Sometimes it stays for a day or two sometimes it goes right back into the 'locked' vibrate mode within an hour.

I've removed every app from my phone that could cause it, I have no automation apps or anything that has a mode that sets stuff like that. I've checked moto's settings (which wouldn't account for ths happening on my Nexus), and I've checked the Google settings in Interruptions and there is nothing set there that seems to cause this issue. Thoughts?

E6533 Dual Lagging and restarting itself & wifi lag

In the past couple of days for no reason my phone when ringing to receive a call will freeze and restart itself, hence, missing the call, I can see the caller ID but no luck answering, upon restarted the call will not be on the call log. It doesn't matter if phone is idle or using an app, any app. I've lost a couple of important calls today. Happens on both lines.

Has anybody had this happened? I'm thinking of a factory restore, but will accept any suggestions before doing so.

Also, when leaving a wi-fi connection, ie: driving away from home, it takes about 3 or 4 minutes lagging, and then it will function normally, what I have to do now is shut wifi off prior to leaving the house or the office, untill I get to a new spot, but sometimes I forget to turn it back on and my plan is running, any ideas?

Both issues I don´t think are related.

I'm on Android 5.02, build 28.0.A.8.251, haven´t done any rooting, just like it came out of the box.

Thank you in advance.
