The LG G4 Beat and the Oppo R7 are medium budget smartphone releases for the year 2015.

While the G4 Beat launched in August, the R7 entered the market earlier in May. They are both dual-SIM smartphones. While LG’s device supports only nano SIM, Oppo allows you to insert both a micro SIM and a nano SIM in its handset. Another point to be noted is the fact that the LG G4 Beat houses a removable battery. On the other hand, the battery in the Oppo R7 cannot be removed. Interestingly, the G4 Beat offers more color options than the R7. Continue reading for more specifications of these two gadgets.

Dimensions, Size and Body Material

The LG G4 Beat may outdo the Oppo R7 regarding width. But, it is the turn of the Oppo R7 to take over on length and thickness. While LG’s handset comes with a size of 142.7 x 72.6 x 9.9mm, the Oppo device measures 143 x 71 x 6.3mm. As can be seen, the width and thickness differences are more prominent than the length. The G4 Beat and R7 weigh 139g and 147g respectively. The LG smartphone encompasses a polycarbonate body as against the unified metal body of the Oppo.

Verdict: Feel light in both your hand and pocket. That is what the LG G4 Beat is with its dimensions and weight. However, talk about redefining style and you might want to lay your hands on the Oppo R7.

Screen Display and Pixel Resolution & Density

The G4 Beat features a 5.2-inch IPS LCD screen with 423ppi pixel density while the R7 comes with a 5-inch 445ppi AMOLED screen. Both LG and Oppo have opted to use the same 1920 x 1080 pixel resolution for their handsets. Additionally, the glass chosen for their displays is Corning Gorilla Glass 3 to make them scratch-resistant. Proximity and light sensors form an integral part of both the screens. The LG G4 Beat has a screen-to-body ratio of 71.88 percent in comparison to the Oppo R7 that has a value of 67.77 percent for the same ratio.

Verdict:Considering the screen size and pixel density attributes, the R7 delivers sharper and clearer displays for the same pixel resolution. But for wide viewing angles, the LCD technology of the G4 Beat screen produces better results.


LG offers its handset with a dual LED 8MP rear snapper featuring 3264 x 2448 image resolution and 1920 x 1080 video resolution. The same shooter in the Oppo handset is a 13MP camera featuring image and video resolutions of 4160 x 3120 and 1920 x 1080 respectively. While both cameras provide autofocus functionality, what makes this feature impressive is that the LG G4 Beat and Oppo R7 rely on laser autofocus and phase detection autofocus in that order. The LG device has a camera shutter key for easy activation of its snapper. The Oppo smartphone does not support this. Regarding front shutters, the G4 Beat integrates a 5MP camera in place of the R7’s 8MP camera.

Verdict: Without any second thoughts, the Oppo R7 cameras showcase a hands-down victory. The bigger resolution values of the back snapper result in delivering better shots as output. Also, the macro mode that is a distinct functionality of this camera helps in capturing close-up views of small items that fascinate the photographer. Again, with a better front shooter, the handset makes selfie shots and video calls livelier than those delivered by the LG G4 Beat.

Hardware, Memory, and Software

Both devices have two octa-core (one octa-core = two quad cores) 1.5GHz processors with 64-bit architecture and Adreno 405 graphics processors. The LG G4 Beat has 1.5GB RAM while the Oppo R7 has 3GB RAM. They have 8GB and 16GB ROM internal storage respectively. This can be enhanced to 32GB and 128GB correspondingly.While the G4 Beat has a dedicated memory card slot, the second SIM card slot in the R7 is used to insert the memory card.

LG and Oppo have preferred to install Android’s KitKat operating system on their smartphones. But they have made a difference to the user interface integrated with the operating system. The LG G4 Beat comes with LG’s very own LG UX 4.0 skin loaded. The ColorOS 2.1 skin takes its place in the Oppo R7.

Verdict:The extra RAM and more storage in the R7 do all the talking here. Not only is operation smoother and faster, but number of files can also be stored in this smartphone compared to the G4 Beat.
