if this the completely wrong place for tech support stuff I am sorry and would really appreciate it if someone would point out where to ask this question.
I already tried contacting Whatsapp's customer support, but they were less than helpful so far.
Since I already explained my problem to them, I'm going to post my e-mail exchange so far.
Dear Whatsapp support
Yesterday evening Whatsapp encountered a problem and asked me to reinstall the application. Trying to do so, I uninstalled the app via the PlayStore and, when trying to reinstall it, encountered error code -11. I originally thought this might be a problem with the PlayStore, but now I'm not so sure anymore.
Things I've tried so far:
Manually remove all remaining files associated with Whatsapp from my phone.
Cleared PlayStore data and cache.
Uninstalled and reinstalled all PlayStore updates.
Reset my phone to factory default.
Tried manually installing an older version of Whatsapp.
Lastly I tried to manually install the latest version of Whatsapp. When I try this I get a parsing error. I downloaded the APK twice to make sure the download wasn't corrupt. This leads me to believe it might be problem with the APK and my specific device, and not the PlayStore.
The device in question is a Samsung I9070 Galaxy S Advance running android version 2.3.6.
If you require any more information I gladly provide them.
I apologize for any grammatical errors, English isn't my first language.
Best regards Marco
And their less than helpful reply, which is the reason I'm posting here, instead of trying to get help out of a robot, or a person acting like one.
