So recently I shipped my nexus 5 to lg due to a defect. The phone was running lollipop via ota and upon receiving it it is only on 4.4.4 and so far I have not gotten another ota. Even weirder is that the phone is running a KitKat/lollipop hybrid. Any ideas as to why I haven't gotten another ota?? (I'm 100% stock)
