These are mid-range tablets, very cheap and with decent hardware performance. They were released in this order: Nexus 7 – 2012, Asus Padfone 7 – 2013 and Lenovo A8-50 in September 2014. This is how they stack against each others.
Designs, displays and sizes
The Nexus 7 inspired Samsung to make a device with perforated dots on the rear panel. It has a weight of 340grams, its dimensions are 198.5x120x10.5mm and the display is protected with Corning Gorilla Glass. The screen is LED-backlit IPS LCD of 7inches, with a good resolution of 800x1280pixels and supports 216ppi.
Do not mistake the Lenovo A8-50 with Lenovo A850, because the second one is a phablet with a 5.5inches display. The tablet has a big display of 8inches (IPS LCD) with the same resolution, but its pixel density is 189ppi. This device comes in four variants of colors and it’s heavier than the other two tablets, weighting 360grams, while its dimensions are 217x136x8.9mm.
The Fonepad 7 is the lightest tablet, weighting 328grams, and its dimensions are 196.8x120x10.5mm. This little guy has an IPS LCD display of 7inches and coincidence or not, it supports the same resolution and pixel density as the Nexus 7.
The Nexus 7 and the Lenovo A8-50 have quad core processors, but the first model comes with a Cortex A9 CPU clocked at 1.2GHz, which couples with an ULP GeForce GPU and it’s backed by an Nvidia Tegra 3 chipset, while the Lenovo tablet has a Cortex-A7 CPU clocked at 1.3GHz, supported by a Mediatek MT8382 chipset, while the Fonepad 7 is powered by an Intel Atom Z2560 dual-core CPU with a clock speed of 1.6GHz, and uses a PowerVR SGX544MP2 GPU.
All three tablets are housing 1GB of RAM and internal memories of 8 and 16GB, expandable up to 32GB, while the Lenovo A8-50 has another variant of 32GB.
Each device comes with a different version of Android: the Nexus 7 operated initially on v4.1 (Jelly Bean) and now it has the v4.4.2 (KitKat), the Lenovo A8-50 still runs on v4.2.2 (Jelly Bean), while the Fonepad 7 had v4.2 (Jelly Bean) and it was upgraded to v4.4.2 (KitKat).
The Nexus 7 has the weakest camera of 1.2MP, which lacks most of the important features. The Lenovo A8-50 has a 5MP back camera and a 2MP front camera. In low light conditions, Lenovo’s camera suffers noise, although it supports HDR mode. The Fonepad 7 has a 5MP primary shooter with autofocus, and another camera of 1.2MP which can record at 720p.
