The sound really sucks even worse after MM, but did install without much ado even while being encrypted. took a while for apps to settle out but eventually in working order now. I noticed there are no settings options on some things, like storage, sound, phone. Some of the user functionality has been axed. So disappointed with the sound, every update since it was new has reduced volume and lowered quality, and now there is no way (that I've found) that you can even access settings for a general sound mixer that works across all apps. Bout done with google, android, and the whole lot. The losses overshadow any benefit (if there is a useful one, I don't know it) other than security (and...how do you know here) with the MM. Just take more away, trim back options, and force-feed a platform that is sadly inept. Getting a S8 next spring if they come out...if it sucks, that will be last smartphone for me. On to a jitterbug and a pda (may see if I can fire up my old palm)
