It was a great phone otherwise but eventually the core patch started boot looping which a reflow fixed for a few weeks before it finally completely died. Ended up getting a OnePlus 6 and it's been fine but I wish I had the 5x as a travel / backup phone. Still rocking my old Galaxy Nexus for that purpose with a custom rom. [0]
