Battle of the two 4.5″ dual-SIM smartphones

Today, we pit two dual-SIM Android handsets that are almost identical in specs but differ in pricing. So if you’re torn between getting the Starmobile Crystal and the O+ 8.12, we might just be able to help you in deciding which one’s for you.

8.12 vs crystal

Design and Construction

We’re not exactly sure to which phone we will favor because looks is matter of preference. We also like to point out that both handsets are well-built and are gorgeous in its own right. Having said this, we’d give each device a score in this category.

Because both handsets have the same screen size and resolution, one would think that we’d call it a tie. But the Crystal has one trick up its sleeve, and that its IPS display. With this type of screen, the handset is able to provide wide viewing angles and slight crisper display quality. 8.12 takes this category away from Crystal because of the shock-proof and scratch-resistant properties of its display.

If there’s a significant difference between these two handsets, it’ll be the audio quality. The O+ 8.12 is the better of the two by a mile, thanks to its loud speakers with pretty decent sound quality.

This one goes to the Starmobile Crystal because of its better low-light performance due to its BSI sensor. In addition, the Crystal has a better front-facing camera (2MP vs VGA) than the O+ 8.12, making it a hands-down victor in this aspect.

Just like design, the performance factor can be very subjective for the reason that each of us uses our device differently. So we thought of basing our decision on the benchmark scores.

As seen in the table above, the score is too close to call. Even though the 8.12 had twice the RAM that the Crystal have, it seems that it was a non-factor in the benchmark tests that we performed. But no matter how close the scores were, we’d still give the O+ 8.12 a slight advantage over the Starmobile Crystal in this segment as the added RAM can be very handy when doing resource-heavy tasks on the phone.

On paper, the O+ 8.12’ 1850mAh battery pack has a slight advantage over the Crystal’s 1700mAh. But there’s more to battery life than the battery rating and having a 150mAh advantage over your competitor is not enough to win consumers. Having said this, we’ll call this one a tie, giving each handset a score.

Specs comparison


With only one more aspect left, it seems that we can chalk this one up for the O+ 8.12. But just to be fair, let’s still look in to the pricing aspect of this match-up. The O+ 8.12 currently retails for Php11,995 while the Starmobile Crystal only costs Php7,990. To be honest, we had a hard time scoring the handsets on this category. On one hand, we got the decently spec’d Starmobile Crystal which only costs two-thirds of what O+ is asking for their handset. The 8.12 on the other hand has twice RAM capacity than the Crystal and its screen has an added protection from scratches and accidental drop.

The O+ 8.12 may have the better screen and extra oomph under the hood, but unless you’re a clumsy user or a power user, you won’t really notice the difference that those two features brings to the handset. In addition, average consumers (esp. in our country) has a higher probability to go for the cheaper option that can basically do most of the tasks that the pricier one has to offer. And for that, we give this one to the Starmobile Crystal for the simple reason that it’s more competitively priced than the O+ 8.12. However, if you have money to spare (Php4,005 to be exact), then the 8.12 will probably be a good investment.

It was a close fight, but the Starmobile Crystal emerged victorious in our head-to-head 4.5-inch dual-SIM Android matchup. It may have half the RAM as the O+ 8.12, but it was able to compensate it with its other features and enticing price. O+ 8.12, with its rugged display and 1GB of RAM, managed to take home the victory. The added features comes at a price though, but if you’re willing to shell out extra dough, you won’t go wrong with this handset.

As for the runner-up, we’d like to commend it by giving the Crystal a run for its money. In fact, had it not been for its slightly pricier SRP, the O+ 8.12 would’ve walked away with the victory. Though beaten, we feel that the cheaper Starmobile Crystal has the potential to win the hearts of the budget-conscious consumers. It’s mid-range specs coupled with a wallet-friendly price tag makes it a viable choice if you’re in a hunt for a decent 4.5-inch dual-SIM Android smartphone.

Editor’s Note: We apologize for missing out on one of the O+ 8.12’s feature (display) and for any confusion that the previous version of this article may have caused. In accordance to this, we’ve changed the scoring and verdict accordingly to fit the changes we’ve made. We also like to thank the readers who politely pointed out our mistakes.

    Better if the Crystal vs Myphone A888 and the upcoming Torque Droidz Blast

    It’d be nice if battery performance was tested on real world use like using the device on 3G, Wi-Fi, talk time, etc.

  3. Oh okay, so 150mAh is not enough to give it to the O+ 8.12? It’s clear that its bigger. How come you made it a tie? I know that usage plays an important role but if it’ll be used side by side, then the extra 150mAh is a nice boost already.

    For those who are not aware, the display of the O+ 8.12 is scratch proof (super tough, really) and is also an IPS. So how did the Crystal won in that category?

    I agree that the Starmobile Crystal is ‘somehow’ a better buy at Php8k (if you’re tight on budget), but O+ 8.12 gives you more at Php12k. Scratch proof, shatter proof, 1GB of RAM, planned upgrade to Android 4.1 Jelly Bean, free 8GB microSD card, great earphones with noise-cancelling silicon earbuds, American brand with their original design (it’s not rebranded, fyi), and an awesome pick up + delivery warranty (to your house).

    All things considered, I think O+ 8.12 is worthy of its asking price.

    • Aura-King

      12K for O+? A good buy? No thanks! its a 2nd hand unit of Galaxy SII and I’m pretty sure that SII will buttfuck your O+ like a bitch…

    • Ay ang cheap 2nd hand lang ang afford.. Scratch resistant ba ang S2? Mag cherry mobile ka na lang para hindi 2nd hand. hahaha! Walang pambili si kuya oh

    • Scratch resistant ba ang S2?

      Opo Boss Sir, gorilla glass po ang S2.

  4. asiong ilonggo

    Lols. Nakatuwa tie sa battery comparison tapos dun performance panalo crystal kahit slight advantage. What a ducking retarded commpaeison. Mukhang me binayaran dito ah

  5. asiong ilonggo

    Lols. Nakatuwa tie sa battery comparison tapos dun performance panalo crystal kahit slight advantage. What a fucking retarded comparison. Mukhan.g me binayaran dito ah

    • 2MP kasi yung front camera, kahit 1GB yung RAM, sabi nga, hindi 4K yung halaga ng 512MB RAM..V

    • ulol! kaya nga benchmark ang tawag nyan 6651<6757, 2711<2713, 23.8<24.1.

      in real life usuage hindi uubra yang 512 sa 1gb. bias paken shet! tie dapat!

  6. how about umi x1? cheap and better than those two.

  7. Check lenovo s720, may qHD 4.5″ IPS display pero 9k lang. :D

  8. It’s obvious in terms of specifications. I go for O+.

  9. If it’s a pure performance comparison, it would have to go to the O+. If it’s build quality, the O+ can take a knife and come out unscathed. If it’s battery life, it might be a bit negligible, but it still goes to the O+. I think the Crystal is a great phone and all, but seriously, how does it beat the O+ 5-3?

  10. Judgeallyouwant

    With that low price, the phone’s durability will not be reliable enough

  11. parang promo ng starmobile ang post na ito, lols.

    you pay premium price sa o+ dahil sa premium spec and features nya which this post barely mentions. pero i find it priced too aggressively for a brand thats just starting up. teritoryo na sa mga samsung at lenovo pinaglalaruan niya.

  12. won’t starmobile will be launching Flirt, 1 Ghz dual core processor with 12mp BSI rear cam for less than 10K??

  13. paki include ang test sa ear piece , mic audio quality , kc yun astra na bili ko is super hina sa ear piece , mic audio is muffled and the ringer is un par .

  14. how about the official aftersales support?

  15. matthew tribianni

    it’s dangerous to do reviews especially when it is haphazardly done. what’s the use of the edits and revisions when the original article has been read? The damage has been done, baga.

  16. one important factor left out, the O+ is a quad band or a world phone, you can use it anywhere in other countries. The Crystal is dual band only that means you need to know if the other country you’re goin have the same band with us or leave your phone behind.

  17. superboink

    Hmmm… I think it was also left out that the O+ 8.12 has the Air Shuffle? Something perky for a consumer I’d say.

  18. Joel Anies

    Wait for the update of O+ 8.12…try kata i1’s new update…:)

  19. i think it would have been better if the comparison is between Kata I1 vs O+8.12 as both have 1GB RAM and then between Starmobile Crystal VS MyPhone A888 as both have 512MB ram.

  20. Dapat mp888 vs Crystal vs Kata i1. Same price range.
