    For anyone using the 1520 on Rogers I found my excessive battery drain issues were related to Location Services aka GPS being enabled. You'll find a noticeable difference with it on and off. Remember, the 937 is missing some of the bands Rogers utilize so it has to work a little harder to penetrate walls and buildings to give us data and LTE. This will cause drain and it did for me big time and soon as I disabled it there was a big gain. I was losing 10%/hr just having my phone in my pocket walking through the underground path at work.

    I have GPS on all the time and I don't have battery drain. But I don't run LTE and instead use 3g only because of the weak 2600 signal. Rogers too.

    I'm seeing an issue where right after unlocking, the screen will be unresponsive for about 1-2 seconds. I saw this while on WP 8.1 DP and still see it after downgrading/upgrading to WP 8.1 + Cyan. Not a serious issue, but a bit of an annoyance.

    Yes thats why you dont, because you set it to max 3G. I have it on 4G all the time.

    Forgot to post 2 ongoing issues I've always had. Not sure if others have these issues with their 937. Any time I reset my phone using the volume down and power button upon reset my date and time is wrong. Enabling "Set date and time automatically" and "Set time zone automatically" doesn't help and still shows the wrong date/time/timezone. It seems to want to default the the timezone to Cuiaba every time. Kind of annoying.

    Second issue is when I'm watching streamed media directly within IE (not within an app like MetroTube, Vevo etc) the phone will reboot itself randomly. Usually happens after about 10 min of watching video from the browser. But usually doesn't happen more than once a day. Not sure if this is OS related or not.

    Any news on when the owners of RM-937 will be getting Lumia Denim update. I am desperately waiting for it.
    Manufacture Name shown on extra + info screen on my phone is : RM-937_apac_hong_kong_222. Does this have anything to do with when I will be getting update?

    So you'll have the Denim update at the same time than people from Hong Kong.
    You can get Denim now by flashing for a RM-937's Finland CV firmware. Or just wait for a month.

    Hello everyone, I lately bought a Lumia 1520 white color (RM-937). I am using it in the US; the phone came with a ROM from Yemen. I flashed the phone to a ROM from Finland and then the UK (both ROM are country variant). My phone get connected on both Cricket Wireless(Which uses AT&T network) and T-mobile to HSPA+ speed. I am not getting LTE; This is not a big deal for me since HSPA+ internet speed is fast enough to get what I need done. I would like to get recommendation as to which ROM (Country Variant) is better suited for use in the US. I already know the whole process of unbranding (Flashing Lumia phones). My phone currently has UK Country Variant ROM installed.

    Flash it with Att ROM RM-940 THEN from dial pad dial ##3282#
    Accept the field Test and choose the setting and then choose the network type
    Choose Maul and click tick mark all the band that will activate all the LTE and AWS bands

    New 937 owner here... on T-Mobile.

    What is the procedure for flashing the 937 to a 940 ROM so I can enable the 1700MHz band?
