Anyone succefully editing manifest?

Hi,
Is anyone editing their manisfest successfully?
I am struggling with it, but wonder if it doable.
I am trying to do it using apkManager. (http://girlintroverted.wordpress.com) Trying to remove things corona forces on us.
I am missing a lot of sales because people with cheap devices cannot use my app. I am getting regular emails with the text that people cannot download my app through Google play cause of device incompatibility.
If I send them the APK it works. But Ansca is forcing some phone, networking stuff that cannot be disabled. [import]uid: 100901 topic_id: 25395 reply_id: 325395[/import]
