Re: Wanting to use one android device as a monitor for another
You can try using one of those "track my phone apps" like Cerberus or something else thats able to monitor the camera.
Here's an easier way. .
Go on Play Store and download Goo Manager. After it installs open the app. Click Menu and find the option "Install Open Recovery Script" it'll flash TWRP.
I also like Otterbox. Defender is what im using but they also make the Commuter. I love my Defender because it also comes with a holster that doubles as a kickstand.
I have 2 tablets. Amazon Kindle Fire HD 7" and a Big Lots D2 7" Tablet (factory rooted - 1G Ram edition $79) they're for the kids as I don't need something obsolete to my Note 2.
