The Marathon M4 has a metallic frame and is heaviest of all the handsets reviewed here. That said, its added heft gives it a solid feel while its compact form factor allows for single-handed use. The super AMOLED display on this device is bright and renders standout colours, but sadly its glass is not scratch-resistant and neither does it come with backlit navigation controls.
When it comes to processing power, the M4 performs slightly better than the Moto G and Asus ZenFone 2 Laser, but not as well as the Yu Plus and the Eluga Icon. Still, it handles Full HD clips and 3D games like Asphalt and Real Football 2015 effortlessly .
Phone calls are clear, its speaker is loud and its music player includes audio equalizer settings for different kinds of earphones.
The M4 has a lower megapixel rear camera when compared to the Asus and Panasonic. However, it is capable of sharp pictures with adequate detail, albeit with some over-saturation.
Its front camera is not as wide angled as the Zenfone 2 Laser, but it takes sharp selfies. Overall, its cams are a bit slow to focus, but this is not a huge issue. You get a number of picture modes including Face Beauty for selfies, HDR, t Filter, Night and PicNote.
Amigo, M4's customized user inter face, includes some nifty features like “fake call“, gestures to browse pictures t without touching the screen, and a “Cha meleon“ tool that lets you use the rear t camera to select the colour palette you want your homescreen to use. But the , best part about the M4 is its 5000mAh battery , which is capable of giving over t two days of service without requiring a recharge.
