    Microsoft RM-1128 Reviews

    Lumia 550 RM-1128 8GB Smartphone (Unlocked, White) is rated 4.4 out of 5 by 14.
    Rated 4 out of 5 by from Quality entry level Win10m phone My new daily driver. Win10m feels much better than Win8.1m. Build quality is solid and feels nice in my hands, although my 3rd party case adds a bit of bulk to it. As always it seems, the low end Win phones are pretty snappy and responsive as their more beefy brethren. A couple app freezes which are probably more to the beta nature of Win10m currently, otherwise apps launch quickly and are responsive. A customizable start screen is great, organizing apps and live tiles to give instant info just by a quick glance is a nice feature for Windows mobile. Speaking of glance, the glance screen is neat-o. The light sensor in the front can detect when the phone comes out of you pocket and display the time along with notifications for any apps you select. Great for when you're just checking the time and don't want to unlock or turn on the screen to do so. Settings are a little buried. I had to look up info on how to change a few things as the Search function in the menu is perhaps too narrow and doesn't bring up the most relevant information. I.e. Typing alerts bring ups nothing, you have to type notifications. Battery life is meh. About a day of regular use, less so with constant browsing and app use. But it charges quickly, so maybe having a car charger or portable battery just in case. Obviously Win10m isn't a platform for killer apps, but it has enough to do most of the things you expect a smartphone to do and do well. Hopefully if a wider install base adopts the platform more app makers will take notice.

    Rated 4 out of 5 by from Solid all around device I am a moderate user who takes pictures, checks social media, etc. I don't really play games. Anyway, my review: -Doing day to day things like Twitter, social media, browsing websites was fine. The screen is a nice HD screen. -I got LTE speeds on this device easily (I'm on T-Mobile), and at most, it would drop to 4G while on a call, but that is on a call. It does have Band 12. -WiFi connectivity is also very good. Everywhere I went that had WiFi, the connectivity was great. -Feels great in the hand. I thought it would feel like a brick but it really doesn't. Not as light as the 640, but light enough. -Sound quality is good. People on the other hand can hear me and I can hear them. Playing videos, the sound is good enough. I have had no issues playing YouTube videos. -The built-in maps are good actually. I worried about the loss of HERE Maps, but Microsoft Maps uses their maps so it's one in the same. -MixRadio works great! -Cameras are good in daylight for pictures and video. However, in low light, the cameras can make the image appear to be yellowish. On the back camera, you have to wait for it to stabilize so that it wouldn't be as yellow. This is even worse on the front camera. Adjusting the ISO or shutter speed can help it be way less yellow, after waiting for it to stabilize as well. Video isn't good in low light so if you like to do video chats at night, this would not be the device for you. You can still be seen, but the image would be very grainy on the front camera.

    Rated 4 out of 5 by from good for the price basing this on just windows phones: we know they suck but this one for $80 does the job well. Purchased to test a few things and its performing great. It can be used for an older person that does not need 1 million apps. Not comparing it to Ifruit or Idroids

    Rated 5 out of 5 by from Pretty phone for the pricetag. It is a pretty solid phone for the price. There are a couple of downsides, one is the internal storage (8GB) but with a fast micro SD Card a lot of apps and stuffs can go directly there and the other one is the RAM (1GB) which has no workaround (other than messing with the paging file). It does work pretty well as a phone and some of the apps available are pretty well done.

    could i install hebrew on that device?
    Asked by: Anonymous
    Yes. Hebrew uses the UI font Segoe WP. This font is included on all phones, so even if a different display language is set, Hebrewbased text will render using the Segoe WP UI font.

    Does this support 5Ghz Wi-Fi?
    Asked by: Anonymous
    According to Microsoft and GSM ARENAS website the Lumia 550 only supports IEEE 802.11 b/g/n which is NOT 5 GHZ. IEEE 802.11 a is 5ghz capable so according to this information, I would say no.
