I mentioned earlier that I saw this problem from a user with a 3rd party keyboard. Do any of you have 3rd party keyboards?
		
		
	 
I do, as I'm a bit of a keyboard wh*re... like really, I think I've tried them all (even the crappy ones).  Currently, I only have the following "keyboards and input methods" available on my note 2:
 - Android L Keyboard (

 - Google Voice Typing (comes with the phone)
 - Samsung keyboard (I'd uninstall if I could, but whatever - comes pre-installed)
 - SwiftKey (duh -- best keyboard available, ever -- convinced that it's not the culprit)
I'll remove the Android L keyboard because I'm not using it.  However, I've had it on here for a while and only started seeing these issues recently.
So here's a thought.  Since the problem we're experiencing seems to involve AdMob (based on the URL previously mentioned: admob-redirect.s3-website-us-east-1.amazonaws.com), maybe we can identify the culprit app based on a review of the applications that integrate with the admob ad network.  Unfortunately, this doesn't narrow it down much, because based on my phone's scan, this is (by a long shot) the most prevalent ad network, with 30+ apps using it (the next most used network on my phone is MobileAppTracking with only 5 apps).  
You can take a look yourself using app brain ad detector:

So -- anyone think it's reasonable to assume that the app is somewhere in this list?  Tried to group them into suspect / recently installed apps and apps that I'm fairly sure aren't the culprit -- but what do I know?  Do you see any overlap between these apps and ones you have?
Recently Installed and / or potentially suspect
 - App Cache Cleaner
 - Music Download Paradise Pro
 - The Weather Channel (wouldn't normally suspect twc, but someone else in another thread I read mentioned the app)
Recently Installed but likely not the culprit based on reputation / prior app use:
 - AllTrails
 - Amazon Wallet
 - Draft Punk 2014
I've had these for a long time and trust that they're not the culprit:
 - CamScanner
 - CBS Sports
 - Cerberus
 - Chromecast
 - Circa
 - DynamicNotifications
 - CBS Sports Fantasy
 - FatSecret
 - GasBuddy
 - Google Opinion Rewards
 - hoopla
 - IPC Cast Proxy
 - LinkedIn
 - n7player
 - Nextdoor
 - OpenTable
 - Pandora
 - Plants Vs Zombies 2
 - Quickoffice
 - Sheets
 - Smart Voice Recorder
 - Speedtest
 - theScore
 - Trello
 - Twitter
 - Yelp
