I recently downloaded Grindr for Android and have questions about how it works based on phone settings. Does the app have to always be open (up on the screen) for it to be active: for the app to update and for me to be seen by others? If I have the app open and then want to do something else like text, email, phone call, web search, etc., does the app stay on and active or does it shut off? If the screen on my phone times out, I see that Grindr has to update or refresh after I unlock the phone. Does the phone changing to time out mode shut down the app? Do I need to turn off the time out feature and constantly have the screen on in order for the app to continue functioning? Thanks for any feedback. I hope that others can post and get answers to similar questions and get the best use out of the app.
