    The phone was delivered early, and worked well. Then when I was trying to connect the service I had some issues. EIN number and everything. After that I was able to accept a phone call, and when I did the audio quality for the next to ear speaker was trash. I can only talk on speaker for this phone. And finally when I accidentally spilled a little bit of water on my phone my device thought it was connected to headphones. And now I have zero audio on my phone. Even when I attach my motto mod JBL speaker. I'm trying to fix the issue at the moment, and after plenty of restarts, and other attempts. No solution so far

    It works just as good as the last one did before water killed it. Fast, big storage, and decent battery. The reviews aren't wrong tho. The sensor doesn't seem to work as I just checked, but I never replied on those things, so it's no skin off my back

    Bad service. If my phone breaks within a year of buying it, it should be covered for free. It broke a month after getting it and you are saying thats not covered? Thats ridiculous!

    It wasn't what I expected. Also, the fingerprint scanner didn't even work

6.3 oz of e-waste

That’s around the weight of a baseball.

That's like 20 dogs digging in your yard for a week.

That's like running a faucet for 3 days
