Telus Samsung Galaxy Note gets a taste of Jelly Bean goodness

I don’t know if Google already does this but the should have a pure Android Version available to the public so the can update their own device

  the problems with that are compatibility and oem/carrier control

  That’s not possible. There are 2000+ different Android devices!

  OEMs are the ones to blame! :P

    Yes because look at the s3, it could be on 4.2.2 but it’s not. Thats cause the s4 is on 4.2.2, so they deliberately stall with the update otherwise the s4 isn’t so special anymore.

      Rooting FTW! :D

I think the ultimate goal for Google was to have a true Google phone. So I think they want to differentiate the term “Google/Nexus Phone” from “Android Phone”. Now that low-end prepaid carriers are constantly advertising affordable “Android Phones”, that really does sort of cheapen the Android brand. If every phone had the latest version of stock Android, then Nexus devices wouldn’t be so special, would they? I used to be against fragmentation, now I kinda see what Google is up to in keeping the Google/Nexus line of devices pure.

I’m surprised you didn’t mention the security holes that are found in older versions of Android. Google has clearly been patching these flaws as soon as they’re found, so I feel moderately secure on 4.2. But when other manufacturers and carriers refuse to update their handsets, they not only deny access to new Android features, they also leave critical security holes wide open.

For the sake of the consumer, this is absolutely unacceptable, and for me is the number 1 reason why manufacturers and carriers must be held accountable for their reluctance to upgrade their Android devices. You would get mad at Oracle or Adobe if they stopped updating their Java or Flash plug-ins to fix known vulnerabilities. Why should Android (or any mobile OS for that matter) be treated differently?

  exactly! well said!

Google doesn’t really care they don’t get paid for specific os version on device. They get paid for using google services and advertisement. Google’s could honestly care less if you have the newest or not, or what hardware your on (apple, blackberry, windows, etc)
nishantsirohi123

then there are consumers whose devices constantly gives them an alert of the update being available. but they are either too lazy to update or aint bothered with it at all

I really don’t see the issue here. Look at desktops: 90% running Windows, but what is the distribution between the different versions of Win? Some are XP, some Vista, Some 7, and some 8. I guess there is a small % still running WIN98 or 2000. Very similar to Android.

Not to mention that GB is a great OS, and I personally was reluctant to upgrade to ICS. Only JB convinced me it’s time to move. And still, I keep my old Nexus One on GB (CM 7) rather than upgrading to ICS/JB- it just works!

I must say that I don’t like being on an old version of Android. I love software updating. I don’t mind if you have ICS but I have an Gs3 and it on 4.1.2. Which is the newest official one. So you’d advise a Nexus for me, the thing is that a Nexus device doesn’t have good enough specs. I wish Samsung would make another Nexus with a 5 inch screen and a 1.8 ghz processor and all that nice stuff. Cause to me Nexii devices aren’t up to scratch enough for me. ( not saying they’re bad!) just my own like
C-Ice

There is a H/W restriction (kernel 3+ require ARMv7 floating point) which dictates current Android distribution. That is main reason why there is more JB than ICS devices at this point of time and also reason why many devices are stucked operative on old GB (great deal of ARMv6 and lot of RAM). That will change some day soon. Fact that there is more JB than ICS telling that Android is not fragmented much due to lazzy updates as it is due to H/W restrictions.
