As a long time Fring user, I didn’t realise there was a problem with it, until a friend, whom I Fring with, told me that he cannot see my online status. I was logged in, and I thought that he wasn’t.
So, he told me that he can’t text me, and neither could I text him. He told me to upgrade to the latest version of Andriod, as I am still using an older version because I had not been able to upgrade OTA.
Anyway, after uninstalling and then failed to install Fring, I decided to let go of the app. My friend also followed suit and removed his, so I guess, by isolating older Android users, Fring has lost a good number of users.
