Would the LG Optimus L9 (I think this is the model) be a good replacement?
Although the L9 has a larger screen, if you look in detail at all the specs it's an inferior phone to the F3. Older/slower CPU, smaller battery, and no LTE. And it costs more than the F3, probably just because of the screen size.
Unless you absolutely must have the larger screen, the F3 is a much better deal.
