I'm just casual user, so no expert. Nevertheless, I have come with this LG Optimus from the outset along very well, even though the manual has been very puny. The setting was fast, one is led by an understandable menu. That you should have a Google account, I did not previously, that I had to re-set. A number of apps already installed. I do not need most, but not (yet) found no way to delete these. With the display I had initially problems (readability), but now I got used to it.
The camera is just so-so (moderate image quality), but I use actually almost never. Radio / MP3 player, I find the sound of her ok. Radio works only with headphones. During a telephone conversation, I sometimes have a slight noise, but by and large the discussions are well understood. Write SMS is impeccable. The operation of the keyboard, and so is very good for me. My husband on the other hand is not cope (to big hands).
With the battery life I am very happy; but is often asked me to stand.
Total: For my purposes, a good device. But I could imagine that intensive users discover more annoying quirks.
