Starmobile Diamond S1, stylish 5-inch quad-core Android phone for P8,990

Starmobile recently launched a new line of Diamond phones, the Diamond S-series where the S is for Style. There are 4 phones currently under this line and the Diamond S1 is the most stylish of the bunch in my opinion.


The Starmobile Diamond S1 features a 5-inch qHD scratch-resistant display. A thing of note is that the display tapers smoothly towards the edge giving it a sleek look similar to that of some Nokia Lumia phones and the HTC One X. This device is gorgeously-thin as well for its size.

Under the hood is a 1.3GHz Mediatek quad-core processor to go with 1GB RAM and 4GB ROM plus a microSD slot for expansion. This phone is capable of support dual 3G SIM cards as well.


At the back is a 12-megapixel BSI camera with LED flash on a matte black panel, while a 3-megapixel BSI camera is situated at the front. Starmobile really likes putting in decent cameras on their smartphones.


The Diamond D1 runs on Android 4.2 Jelly Bean and supports OTA (over-the-air) software updates. It also has Starmobile Sync which allows you to quickly transfer Contacts, Messages, Calendar, and other data from your old phone of any brand to the Diamond S1 via Bluetooth.

The Starmobile Diamond S1 is already available for Php8,990 with colored red and yellow casing options.

          • elmer

            ganda nga ng chipset nito eh kagaya ng sa lenovo A850 16k- 17k antutu score

          • ok naman yung Diamond S1 it so Happen na bagsak ng niece ko kaya nabasak ang glass panel peru ganun pa man gumagana pa rin sya.. (Y)

  • Kaya po niya HD games mataas kasi ang clock ng GPU nya kahit Mali-400MP2 lang 500Mhz naman yung clock nya kaya mas mataas yung score nya sa 1.5GHz na MTK 6589T. Look at Flare S w/ same chipset smooth ang Asphalt 8 even on full settings yung graphics…

    pwede po ba makapagVideocall gamit ang starmobile S1?

    • yes,. pwede video call even those many social apps with video calling supports.. super compatible po ito, and even sa games sakin, marami na ko high end games na nasubukan.. then kahit mag multi task ka it runs smooth pa rin… just dont over expect too much sa kaya ibigay ng s1.. use as what the specs indicated can perform..

      (Baka kasi ung ibang mobile addict users eh gs2 kasing rate ng GALAXY NOTE 3 )

      Why you guys should buy this phone,

      Its not just because of its low price.. But its on the performance level…
      even games, apps, video calls, great camera captures, internet surfing etc.

      Super affordable na! Good Looks pa!

      thank u..

      • kendra

        oo ang ganda ng built ng fone na to, pati yung cam sobrang linaw,panalo! sa games ok sya, may 15 games na nakainstall sa s1 ko, smooth naman sya, wala kong masabi, i guess worth it nga ang pera ko dito and consider its design inside, ang crisp ng mga images kahit qhd lang parang beyond HD na sya e. u’ll never regret it 🙂

    Bumili ako ng Diamond S1 pero may naencounter akong problem, kung tatawag ako ng number, nawawala ang display niya at naghahang-up. I sent a mail to happyman sabi try ko daw factory reset pero ganun pa rin. Is there any suggestions what should I do? Nasa ibang bansa na ako ngaun so I am not able to do for a repair now. You can mail me at [email protected]. Thank you very much.
