Tests Android 5.0 on the Nexus 7 2012: a little worse KitKat – 3DNews

The original Nexus 7 was released more than two years ago and is one of those times when the Android platform just tried to break into the tablet market. Perhaps this is why the unit seems older than he is in reality. Usually the device show their strengths and weaknesses, after a short period of use, and they do not change after weeks and months of work, but with the Nexus July 2012 the situation is different.

Although the tablet is initially highly praised journalists, eventually reputation device somewhat deteriorated. The device is known relatively low productivity – this problem is primarily due to the low rate used flash drive. However, Google has decided to update the tablet to version Android 5.0 Lollipop. A Anandtech journalists after the launch of the final Android 5.0 decided to conduct a comparative test of the previous version of KitKat and fresh Lollipop 8 GB version of the Nexus 7.

After flashing the reporters found a few features. Firstly, encryption devices on standard off (must be manually) – apparently, this feature advertised Lollipop is standard only on the devices that came immediately preloaded with Android 5.0. Both the Nexus 7, Nexus 10, Nexus 5 and Moto G 2014 behave the same after the upgrade.

Second, Nexus July 2012 did not receive a preset sheath Start Google (Google Now Launcher), so that the home screen remained the same as in Android 4.3. Download the shell just after installation and it works the same way as on the Nexus 5, 6 or 9, but Google did not include it in the firmware of older Nexus, who initially were not supplied with it.

The rest of the users will be all innovations Lollipop except those that are not supported by hardware Nexus 7 2012 – mainly small things.

Screen and performance

The density of dots Nexus July 2012 is 216 ppi. This is the lowest among all the devices that are yet to get the firmware Lollipop – the other indicators are around 300 ppi or higher. Lollipop actively uses thin fonts and lines, but fortunately, even on relatively old screen still reads well. Some small interface elements differ little blurred, but still do not look so bad.

As for performance, in general, everything was a little slower, but the difference is still usually insignificant. Journalists measured with a stopwatch during cold start device and run applications on the tablet with firmware KitKat and Lollipop. All measurements were performed three times, and then averaged.

The most serious drawback – the download speed unit: Lollipop cold start takes about 20 seconds longer, which increases the waiting time is about 1.5 times. Most applications have also been tested for longer load, but generally not much decreased performance and in normal use the difference will hardly be noticeable. Do not expect better performance and multitasking – all the old problems due to slow flash memory, remained in place.

Time autonomous work

In Android 5.0 Lollipop, as you know, Google has made great efforts to ensure that the increase in energy efficiency platform initiative Project Volta, and early tests Android L smartphone Nexus 5 gave great hope. How did behaves final assembly platforms on the old Nexus July 2012? Journalists Anandtech conducted a test to surf the Web via Wi-Fi and operation of the device in WebGL with an average constant load on the CPU and GPU.

The tablet worked for almost exactly seven o’clock as KitKat, and the Lollipop in the test web surfing via Wi-Fi with the screen brightness of 200 cd / m 2 , and about 3 hours and 40 minutes in the test WebGL. It is worth noting that we are talking about the battery device that is in use for two years. So on other devices Nexus 7 results may be better or worse, but the upgrade from Lollipop should not expect positive results.

In any case, even though Android 5.0 does not increase performance, update brings more problems. So we can safely update the sake of thousands of new API, compatibility with the latest applications, the new “real” interface runtime ART and other innovations of the platform. It is necessary to stress once again that the performance measurements were carried out on the 8 GB version of the Nexus 7, 2012. It is possible that the 16 GB and 32 GB models will get more benefits from the update, as speed indicators flash at them a little higher.
