I installed UT for the first time mid-July and then reinstalled for the second time a few days ago, in the hopes that any fooling around I did would resolve itself.
I had attempted to install Linphone in the terminal without success, and perhaps entered commands that affected the phone.
I can see that I can easily delete photos in the Camera Roll (with 1 click on the red button), but takes many clicks of the red button from the Gallery app.
I switched on the Dev mode as suggested above but still can't delete apps of delete a conversation in Teleports.
I'm basically brand new to Ubuntu Touch so I can't say for sure that the phone was working better before I perhaps entered a command that "broke" the phone.
Doesn't reinstalling UT reset any changes I made?
