Just thought I'd share what I've found about installing WhatsApp on Nexus 7. Much thanks to Astrix from nexustablets.net and StrangerWeather from xda-developers forums!!! UPDATE, 12/02/12...Ok I've tried the lastest version (2.8.8588) of WhatsApp and I've notice it is now giving out 6 digits instead of 3 digit code. For now use this version, WhatsApp version 2.8.4776 ***For those of you who already installed the lastest version of the Whatsapp, go ahead and unintall and install the v2.8.4776 above then redo step #2.*** Required apps: A. Whatsapp apk (since it can't be download via Google Play store, download the apk from the link below.) B. Appguard apk: SRT AppGuard (don't worry about the German, the app is in English. This also can be DL using your N7, but you'll have to click and hold the "Download der appguard.apk" and Save link as.) 1. Install WhatsApp, once installed, close the app without running it. 2. Install AppGuard - Start up open/run appguard. - Select "Secure a new app" - Select "Whatsapp" - Appguard will take you through 3-steps: [*]scan and secure application [*]Uninstall existing application [*]Install secured application Once the process is completed, within Appguard, you'll need to change Whatsapp Permissions by removing the setting for "Phone calls - read phone status and identity" 3. Download and install Bluestacks on your PC: BlueStacks App Player 4. Select "Messaging" and install WhatsApp on your PC. 5. Input your mobile number. You should get a text with the 3-digit verification code. Be patient, it can take few minutes. 6. Once you have your code, go back to your Nexus 7, run WhatsApp, press menu (3 dots on bottom right corner) then input the code. And you're done! Enjoy!
