Call quality

So far, the Alto A2 actually proved to be a notch above the flock of lower-end devices (save for the display), but when it came to call quality, things really went downhill. Namely, while the microphone is of passable quality, the speaker is just downright bad. Said more explicitly – the other side will hear you just fine, but you may have trouble identifying just who that stranger is, as the sound is muffled, and just not up to standard. If you place upwards of a few calls a day, then we'd seriously recommend you test this aspect of the phone before you pick it up.

Battery life

The user-replaceable 2000mAh cell inside manages to keep the Alto A2 afloat just long enough for you to get done with your day, but it's unlikely to muster enough willpower to go through the entirety of a second, unless you keep brightness to a minimum at all times. That's because things get especially problematic if you have to crank it up, so do take a moderate approach.

We measure battery life by running a custom web-script, designed to replicate the power consumption of typical real-life usage. All devices that go through the test have their displays set at 200-nit brightness.

MediaTek's ultra low-cost chips have matured and proved to be capable enough to handle the needs of users shooting for a low-end smartphone. And a stock Android experience is nothing to sneeze at, by the way. This would have actually made the Gigabyte GSmart Alto A2 a phone worth your serious consideration, was it not for the out-of-a-horror-flick display and disappointing call quality. In fact, these two are so problematic (especially the former), that they overshadow every other issue one might have with the phone. The other problem with relatively obscure device like the Alto A2, is that both availability and pricing can be quite hectic, depending on where it is you call home. A quick search of ours brought back a compelling price tag for the dual-SIM Alto A2 – about $180. And while the phone doesn't excel in any particular venue, it's a decent deal, if you can't get your hands on something like the Moto G, that is.


  • Build quality is satisfying
  • Powerful enough to hold its ground
  • Relatively decent camera
  • Good price/quality ratio


  • Massively underwhelming display
  • Call quality is a particularly problematic area
  • A bit too heavy (6.2oz/175g)
