Owners are about to be complaining for the RAM usage on their smartphones reaching unacceptable levels, affecting the day by day usability of Google's Nexus devices.
RAM usage on pretentious devices has spiked up to 1. 2 GB leading to issues such as launcher restarting and also the keyboard being shaky while typing. However apps are also have reported to be crashing, which is obvious since this can be an issue relevant to RAM.
While the issue is not extensive, (which is a little strange) it seems to have only affected some sort of selected devices.
We have got a Nexus 5 smartphone in out apartment but it is working merely fine and currently does not report any kinda issues as this can so visible from the screenshots from owners about the Tracker.
Great news is that a fix is gonna be released soon. The worst news is that it will have to be packaged into the next firmware update (5. 0. 3 suppose to be), which will take time to implement.
As with the software and more importantly newer along with overhauled versions of firmwares, these issues are normal. The same occurred with the iOS 8 also with Android is by no means perfect. Thankfully Google releases a software update for affected devices soon as a device reboot is apparently the only temporary solution for now.
