hmm. seems like a hardware issue then. i really tried to like the phone..used it for 1 day and then realized it's not for me. although those speakers are amazing, the phone is HUGE for having such a small screen (i'm used to the nice, bezel-less LG G2) so it isn't really worth it for me to spend $350 on. plus, the battery was pretty bad. immediately after taking it off the charger overnight, it dropped to 99% within a minute..within like 30 minutes of morning usage, i was already down to like 82% (which reminded me of the Droid DNA days with it's awful battery...) compared to my G2 which stays at 100% for about 1.5 hours and 20 minutes screen on time. by the time i leave the house in the morning for work, i'm typically at 95%. the M8 was at like 82%. i sometimes get home after work and my G2 is at 75%. the M8 was at 30% after light usage throughout the day. yeah, idc what evreyone says about the M8's battery, it just isn't good enough for me.
