I was able to get helium to link to my nexus 5x, and I did a restore from my old galaxy s5's backup. The call logs transferred just fine, but I don't see my old text messages anywhere. I'm fairly certain my technique was correct, as I have done backups and restores on a galaxy s5 using the same procedure. Is there anything that needs to be done differently to get texts to properly restore on a nexus 5x? Do they get restored to a different location than the stock messenger application?
