I love the phone and everything about it, except the fact that i cannot stand mms! And yes the Call center was not helpful or useful for myself! I can now receive mms messages but cannot send them! It is really frustrating and inconvenient! Wish there was a way to fix and figure this all out! Another thing is that there are really no assessories/phone cases or good ones for this phone! I need a case with shock proof/hybrid! They do not make then or i have not been able to find one! Another thing is that i still have not been able to change settings, like text messaging, how to change text settings, spacing and prediction words and so on. Settings does not have a lot of options line the galaxy did, in which i go not like either! So yes, I'm still learning the phone, unhappy about certain things, but Other than that, i absolutely love the phone! I recently switched from a galaxy s3 to this and am verry happy with the phone and quality!  :)

but this phone not supported for otg.

my lg pro lite proximity censor is not functioning properly, how can i manage that. or where in the setting can i manage

This model not recommended as service centers and call centers are not trained to fix issues for this model

LG d686 is the worst in the segment. Issue is service center and customer service team are not equipped to handle the complaints for this model.

i own this phone for 2 months. and im quite happy with its quality especially its signal quality. from my experience with other top brand phone,samsung,sony,etc this one is by far the best in signal quality. i use alot its 3g for internet. and im very happy w its signal strength. this is the main reason why i bought this phone. other weakness that u said above doesnt really bother. its still acceptable for me... for me it is useless to own a top grade performance phone bt with dissapointing signal strengh. i will continue buying from Lg for their next future product perhapz LG G3..
