  • S6 marshmallow update T-Mobile???? Posted via the Android Central App
  • Yeah, really! T-Mo is always behind the curve when it comes to updates. Posted via Android Central
  • Actually until this last cycle with Marshmallow, they've been the quickest. I was on AT&T before I switched, and I monitored this for about 2 years. T-Mo was first typically, then AT&T, and then Verizon. When the security updates started, T-Mobile was the first out of the gate until February this year. Verizon then went from stone last to first on a bunch of Marshmallow updates. Posted via the Android Central App
  • Thank you for pointing that out , torbach 1. T-Mobile up until Marshmallow T-Mobile was usually the first carrier to roll out software updates. Sprint was usually right around the corner with Verizon and AT&T being one of the last carriers.
  • T-mobile is dirty now. They are purposely slowing out updates on older phones to sell the newer models. T-mobile has changed for the worse
  • Wow, talk about jumping to conclusions.
    Given that the HTC M8 and M9 got Marshmallow
    and the LG G4 and G Stylo received Marshmallow Maybe, just maybe the problem is Samsung being slower than usual to push these updates out.
    And just maybe Samsung prioritized the larger carriers this year.
  • I got my update on my s6 last week
  • Waiting for the Note 5 update as well. Even Verizon beat them by a significant amount.
  • Nah. You have to spend another $700 to be eligible for software updates.
  • Yeah really, it ticks me off.
  • Note 5 T-Mobile? Posted via the Android Central App
  • Got the update last night. It seems to take a long time to finish once it got to the part where it "optimizes" your apps. Not sure if it's just mean. I don't have a ton of apps, but I guess I have a decent amount. Will have to see if battery does indeed improve. That'd be quite nice if true.
  • It always takes a long time and it optimizes the apps on the first boot up after an update because the cache is cleared. Posted via my Nexus 5X on T-Mobile
  • Optimizing took forever for me also Posted via the Android Central App
  • Any phone with the new(ish) Android RunTime (ART) will take a long time to optimize when an app is installed for the first time or when the cache gets cleared (which is the case for updates). Completely normal, subsequent boots will not take 1/20th as long, unless of course you're applying an update. Posted via the Android Central App
  • Good thing they're getting rid of it in Android N Posted via S7 edge
  • I agree. What's funny is AC wrote this whole article a while back saying how much faster Marshmallow is doing updates. On encrypted devices.
    I was like all "Huh"?. Posted via the Android Central App via T-Mobile 4G LTE-A on a Samsung Galaxy S7 edge
  • After all the app optimization I got a screen saying installing apps and it stayed there for a while... Seems fine now, just I never had that before. Posted via the Android Central App
  • Installing now on my T-Mo S7 Edge.
  • So good to see an update with the April security patch so soon. Also improves the screen sensitivity and haptic feedback. Posted via the Android Central App
  • Not even the Nexus phones are as up to date. Hard to bash Samsung at this point for updates.
  • If you own an S6 it's easy to bash them.
  • Just installed on my S7 Edge Posted via the Android Central App
  • Does haptic feedback feel different? Posted via the Android Central App
  • Yep Posted via S7 edge
  • I find it to soft and I can't adjust it any higher Posted via the Android Central App
  • Started downloading on my S7 Edge. Clocking in @ 147mb for the update Posted via the Android Central App
  • What about a update for Note 5 it is ridiculous it's April and no word on 6.0 update from T-Mobile I'm glade is not my phone. Posted via the Android Central App
  • I have a couple friends that are store managers for T-Mobile. Was talking to them last week about Marshmallow and they said they they've been hearing rumors somewhere around April 8th. Again it's just rumored, but that is what I heard.
  • It's a Note and T-Mobile has a much more modern network and services to provision for. But, it doesn't make the wait any better, I agree! Posted via the Android Central App via T-Mobile 4G LTE-A on a Samsung Galaxy S7 edge
  • When will t mobile release marshmallow for s6
  • Never
  • Hopefully it fixes the random screen taps I get. I rarely use the split screen functionality but the phone has done it on its own a bunch of times on my S7 edge.
  • same thing happens on my S7. hopefully it gets fixed.
  • That issue is all but fixed on my S7 after the update. Very happy here. Posted via the Android Central App
  • It has fixed the over sensitivity of the screen, so I suspect it will fix that issue. Posted via the Android Central App
  • Received update, working great! My S7 has worked fantastic since day one. Couldn't be more happier. I own just about every new device including the iPhone 6S. The Samsung Galaxy S7 is without a doubt the best device to date. Everything is just perfect. Fast, great hardware and perfect size.
  • Got the update, but now my S7 says my phones OS has been modified in an unauthorized way.
  • You probably rooted your phone!
  • Nope. Never rooted.
  • That sucks! I hope youll get your phone repaired so you can enjoy your new phone again!
  • Do a factory reset. Posted via the Android Central App
  • Did the trick, thanks.
  • :) Posted via the Android Central App
  • You can't root the T-Mobile Galaxy S7 or S7 edge. Posted via S7 edge
  • Did the update early this morning so too early to tell but seems smoother, screen less sensitive, and my battery % is not dropping as fast. Though I was not concerned about the battery performance. Posted via the Android Central App
  • Completely agree....much much smoother when scrolling the stick samsung browser.... and my favorite game 8ball pool seems to be handling much better when moving the stick around....hope it's not a placebo effect
  • Updated my S7 earlier but haven't used it enough to tell any differences. Think I will put my sim back in it from my 6P and use it for a few days to see if anything has significantly changed. I wasn't having too many problems with the S7 other than the occasional jank. Posted via the 6P!
  • I notice one change in the stock Calendar. After the update, you'll see the name of the event on the calendar instead of dots...
  • Heard about this last night. Suppose it will be to me eventually Posted via the Android Central App and my Galaxy S7
  • Dont wait for it to come to you! Go to the update setting and manually update your phone!
  • S7 updated at 9:30am today. Posted via the Android Central App
  • Got the update this am. Just finished it so can't really say much yet. Baseband updated to PC8
  • Update applied. Will see how it goes.
  • I notice one change in the stock Calendar. After the update, you'll see the name of the event on the calendar instead of dots..
  • This is great. I see that it has the April security update. Good job Samsung and T-Mobile Posted via the Android Central App
  • I notice one change in the stock Calendar. After the update, you'll see the name of the event on the calendar instead of dots.
  • anyone notice any changes in battery usage? Is Android System/OS still the top drainer?
  • Has there ever been any Android phone where Android System has not been the top battery drain? It's logical that the OS of a phone would be the thing that consumes the most battery.
  • Yes. For me at the moment, in this order: screen, phone idle, Android OS, Android system. And that is normal for me.
  • Interesting. On my 5th android phone and have never seen anything else higher than the system with any of them.
  • I am not 100% certain, but I BELIEVE that most of what I've read indicates that MOST users state that the screen eats up most of the battery. Unless of course the phone isn't used much and the screen isn't on (mostly idle). Would be interesting to see more feedback on your comments from other posters here.
  • That was fast. Good one, Tmo! Posted via the Android Central App
  • Has the Note 4 ever got a security update? Posted via the Android Central App
  • I think mine (T-mo) did just once, right after they were announced. My GS7 ran unusually hot for a few minutes after the update, but returned to a proper temperature shortly.
  • You people need to own a Nexus, Iphone, or Windows Phone if you want updates ASAP or just stop talking.
  • How about not. If everyone takes the easy way out, the problem will never be fixed. As you can see, Samsung is already listening. Or so we hope. Posted via the Android Central App
  • Only change I noticed is the Always on Display clock changed on its own and although I can see the clocks in the settings, I am unable to select any Galaxy S7 Edge: Silver Titanium
    Posted via the Android Central App
  • I got the update, but it doesn't fix the video lag in slow motion mode or in 60fps mode. I've replaced this phone twice and am on my third one already. These issues are quite a bummer.
  • Just curious, whose the Carrier and where did you buy it? Posted via the Android Central App via T-Mobile 4G LTE-A on a Samsung Galaxy S7 edge
  • I still get wifi dropping out even after the update. Does anyone else have this issue? Posted via the Android Central App
  • No. Signs of a bad access point, friend. Are you on 5Ghz? Posted via the Android Central App via T-Mobile 4G LTE-A on a Samsung Galaxy S7 edge
  • easily switch from any android to galaxy s7
  • So apparently since the S7/S7 edge is the latest and greatest, will it go down the same path as the S6/S6 edge? Update for a few months after release than nothing, no more updates. T-mobile sent out updates to be ready for MM but still no MM. And the dang security updates never happen, the last one that came out is Dec 2015. Don't plan on buying a new phone just because of updates. Makes no sense at all. Posted via the Android Central App
  • C'mon AT&T.....
  • Great - now can I have the Marshmallow update for my Galaxy S6? You know, the phone that was the effing Samsung FLAGSHIP until a few weeks ago? I love Android, but I'm disgusted by how long updates take if you don't own a Nexus device.
  • My T-mobile Galaxy S7 phone seems to lag just a little now with the update installed. Movement used to be lightning fast. I would do a minimal flick of my finger and scrolling would move quickly down to the bottom of the list. Now when i do the same flick, the scrolling slows down and I have to flick my finger a few times to get to the bottom of a list. The phone feels slightly slower while opening Facebook, Instagram and Pinterest apps too. It takes a little longer to show Instagram video content on Wifi now. Before the update, I couldn’t tell if my phone was on Wifi or T-mobile’s 4G LTE data because the videos would load quickly at about the same rate. Now, I can tell when Wifi is on because the videos take slightly longer to load. My Wifi connection has not changed before or after this phone update. This is my initial findings so far. I updated a few hours ago so i haven't come across other issues yet.
  • I am running an unlocked, international version S7 Edge on T-Mobile. Anyone know if that device will get carrier updates?
  • Just installed mine. We'll see how it goes in the next few days. Hopefully it fixes the palm rejection issues, which is the only thing I've encountered. I have large hands and every time I hold it in a certain way, the corner of my palm touches the edge and it registers as a touch. Doesn't happen often unless I'm laying down and holding it (don't judge me). Everything else has been great so far and I don't expect the update to change that.
