For half year nexus 5 phone was worked like butter and too Brilliantly with Regular Software Updates so you are always have New Android version in your circle, but the golden period ended soon, in only eight month Phones Touch screen started causing issues.
Call to Tech support of LG and I found Service center 15 km away from house. since Samsung Nokia and Micromax service centers are in main city but not LG service center, spares were not available as usual and it took weeks to arrive. after half month later front camera not getting on for no reason. poor Support from LG service center, even NO RESPONCE. you just have to adjust for days and days without proper information for you device.
