My last phone was LG G4. I don't have any complains about it, just that it doesn't work anymore. (The repair shop say that main memory chip have broken down.)
What I liked the most about it:
Camera - I mainly got this phone for the camera. I wanted something quit good to take pictures. I am not professional, just for my hobby. I really liked manual mode to play with and the quality was good for me.
Dual SIM card - since I am traveling a lot it was handy to use my main card and to just get a cheap local one.
SD card slot - since I like taking a lot pictures to have more space for them. And that is what saved them all when the phone broke.
You might also want to check Asus ZenFone 5. Hope that helps! Let us know which phone you buy. Would be interesting to read a review from you. :)
