I loved the M8 so much, it had everything and still looks amazing in my opinion. However, the screen is not as bright as the M8 screen even. I know someone will say I got a bad screen but I think it's by design...I find the m8 brighter and whiter that the 10. Then there's the absence ofvthe it blaster...I still pick up my m8 from time to time for this. And lastly the battery performance had started to drop even though I have been very careful with regard to overcharging.... My battery peaked about 5 months in and now I'm noticing it's degrading slightly more and more as the weeks go by... I bought this phone in October 2016 so I'm a little bit upset but this. I have been extra careful with the battery, even only charging on a 20% -80% cycle but still it's degrading markedly... I've done all the resets and cache wipes... BlinkFeed is not what it used to be and is ghastly now with the news republic service. I wish I had waited for the lg v20 which has removable battery and ir blaster and good audiophile grade sound.... oh well...
