    Sir can u please post a review about the phones selfie camera.

  • August 6, 2016 at 10:25 pm

    Please review your post very well Mr. Mobility Arena, there is no way a 5.2 inch phone with a screen resolution of 720 by 1280 HD will translate into 424 ppi. It is absolutely impossible even wuthout a ppi cal.

    • September 17, 2016 at 7:36 am

      What has PPI got to do with screen size?

    • August 12, 2016 at 8:13 am

      Hi Minhaj,

      No; it won’t. The specifications sheet does not include that LTE band.

      Hello khalid,

      Ufone (Pakistan; right?) uses the following bands: 900 MHz, 1800 MHz, and 2100 MHz. All those frequency bands are supported by the Infinix Hot S. So, yes; it will work on Ufone.

    Dear bro hot s x 521 no battery timing kiya hai or charging flash hai note 2 jaisy ya single ??? Plz reply

    Jojo, I dont think you really know what ppi means. It is the product of your screen size and your screen resolution. The higher the screen resolution and the lower the screen size, the higher the ppi, and the more the ppi of your screen, the better the screen quality in all respects. Mr. Yomi, the writer of the post I commented on has since effected the necessary correction, i.e. from 424 ppi to 282 ppi as you can see in this post. This is because he is not a layman in this field. Lastly, I want you to know that technical language is for people with technical knowledge-Jojo take note.

      Infinix hot s comes with 5.2 inches, 1080 x 1920 pixels, 424 pixels per inch (PPI) what’s all the fuss about?…

  • December 3, 2016 at 1:32 am

    No, Lamerch, the one in question comes with 720p and not full HD, check the specs very well

  • December 3, 2016 at 8:58 pm


    The Infinix website lists the Hot S display as a HD display. HD aka 720p means a pixel measurement of 1280 x 720 pixels.

    So, Attahiru is correct. The Hot S has a 1280 x 720 pixel display, not 1920 x 1080. That means the PPI is 282, not 424.

      It supports 4G, but stability will depend on your network and your location
