T-Mobile LG G4 receiving security update as LG Leon gets Marshmallow


T-Mobile is sending out updates to two LG smartphones this week.

First up, the LG G4 is receiving a security update. The update weighs in at 84.4MB, and if you haven’t gotten it yet, you can manually check for it by going into Settings > About phone > Update Center > System updates > Check For Update.


Meanwhile, the LG Leon is now receiving an update that includes Android 6.0.1 Marshmallow. The Leon was previously on Android 5.1.1, so this is a big update for the device, especially considering that it’s a lower-end device that launched a year and a half ago.

Also included with this LG Leon update are Android security patches. To grab the LG Leon’s update, head into Settings > About phone > System updates > Check for update.

Thanks, Weilei!

    Marshmallow on the Leon? Hooray for updates to lower-end devices!

  • George Salcedo

    My wife’s old Leon is laggy as hell, maybe this will help but not counting on it.

      Like mine i had 5 apps but had to go to 3 and its bad now with 3 I had it for 8 months and had to get a different one the k7

  • Jonathan

    Does anyone want to install it (on the Leon) and report back?

    • Hector Escobedo

      Yeah I would like to know too cause it’s already limited in space as it is

      • Jonathan

        I decided I would just do it, since the Leon is just a play toy for me. Appears the update is not available to me yet. :/

        • Samuel Winchester

          I don’t think anyone can get it yet

    I’m hoping this will solve my memory issues. I think with marshmallow (hopefully implemented here) you can use an SD card to extend the “internal” storage. So now it will be like I have an extra 16(ish)GB of internal storage, and I shouldn’t get the can’t get txt messages or voicemail messages.

    Also…it would appear to not be available to me yet also.

    I think T-Mobile jumped the gun with the news saying it was released on December 5, 2016 because I don’t think LG has put the rom on the servers yet for OTA push or the PC update route normally when there is an update you can use your PC and LG PC Suit to get that update right away but not with this one which is Android version 6.0.1 and TMO version H345K which is a little strange normally there would be a 10 before the letter like h34510k so the h345k looks wrong to me. I been waiting a year for this stinking update I sure hope they make it available soon.

      g4 or leon??

      • martin

        Sorry G4

        • George lopez

          Did you do a factory reset? Oh wait, it’s the G4….that phone is a pile of $hit

        • martin

          Haven’t had any problems with it till now, wouldn’t exactly call it a piece of shit, awesome camera and better than TouchWiz. I’d prefer a native Android but hey I didn’t pay for it.

  • George lopez

    There are tons of complaints about the boot loop issue. Where you been brah?

    • UltramanX

      Yeah… and I found out there were complains too for the LG G5 and the LG V10. So finally no more LG for me, needed a new phone and was between the iPhone 7 and Galaxy S7… went with the iPhone as it was cheaper than the S7 (go figure!)

      Back to the LG G4, it was send back to LG. I never contacted Customer Support, just created a repair ticket, shipped it. LG says it fixed the issue (free of charge) and I should be receiving it next week.

      LG repair issue was: Flash Memory as pointed out by all other users that had the boot loop issue.

      LG will need to work really hard to get me back as a customer.

    • Samuel Winchester

      I just got done installing it and it isn’t Android 6.0.1 it’s just an update for Android 5.1.1 T-Mobile lied I think I’m switching away from them unless T-mobile can make this right I’m done they shouldn’t have lied

      • Expert
