Nothing but problems with nexus 5. Call drops, can't make calls, can't send texts, can't receive calls. Have tried setting to 2g: this resulted in better signal strength but same issue of not reconnecting to network properly. At one point I had 2 nexus 5 and galaxy s3 all with Vodafone (1 contract 2x payg) and guess which phone performed the best the galaxy s3. Never had these problems before: old HTC desire not have this issue. All comes down to hardware/ software of n5 a serious problem with fringe connectivity experienced in the non urban environment. S3 time without signal 4‰ nexus 5 anything from 20-35⅝ fine if your in the city of useless if your in the country.
