Been using it for 1mth+ and so far this is 1 of the best android phone.
My 1st LG phone as well.
(I have used Samsung, HTC previously).
In terms of UI, is simple and easy to use.
Many commented the colours are not 'bright' however I find it pleasing to the eyes cos over saturated colours might be bad for eyes.
Though I have to say the speaker at the back is kinda awkward but is ok for me cos most of the time Im using earphones.
Im also using the glass protector from Adix which is smooth and SGP slim armor.
Perfect match so far.
note: Im not promoting the phone, just sharing my experience.
