Oh, I will, fairly soon. Sorry for not mentioning that. Being on welfare, I got the phone for free through a government program. So, yeah; but only used it for listening to YT videos while fixing lunch, since the phone service was very spotty. I also got my old Verizon 3G flip phone for free from my dad, and the 3G service ends this year. So when I can, I will be buying a newer phone with far more space on it and far more memory.
That said, I appreciate your other point, too. Thanks. I was already well aware, increasingly all too aware, of the limited space. But while I agree it isn't worth working to free up all of the original free space again, being the curious sort, I'd still like to know why I was able to install and run a dozen or so apps for a year or more without any problem, before having to gradually and eventually uninstall all but one of them (sorry; I didn't mean to lie in the title), nor why I had to free up 194MB of space last night, by uninstalling two of the last two apps, to install a 2.5MB one (huh???), nor why it would probably take doing a factory reset to finally free it all up again.
So, again, being the curious sort, and suspecting there's more to it than my browser favorites, after clearing the browsing data, I'd still like to know why, if one of you or another would be able and willing to answer my question. I really would.
