The smartphone sony are good, people who have experience with cellular sony xperia. performing well without giving problem for much time.I have seen with LG cellular tend to give problem. In my home two have problem already. LG G2 And A LG G3.
My Xperia Z3 on Verizon had overheating and camera shutdown problems with its 4K video and driving GPS. Its headphone output was terrible too. My LG V10 and even mega-outdated iPhone 5C (which I still use as a wifi media player) never had these problems.
