Public bug reported:
When opening new tabs in the browser, it decides if it should close
existing ones based on level of free memory available in the system. My
understanding is that this is currenly set to 30% percentage of memory
in the device.
There are two issues with this approach and setting:
1) a percentage means that the threshold changes from device to device. While
theamount of memory needed to open a webpage is not device specific. For
example at 30%, the browser would close open tabs if there less than 1.2Gb mem
free in a 4Gb device, but will only need 300Mb free on a 1Gb device. This is a
very large difference.
2) In M10 with 2Gb it requires 600mb free. From idle, just opening the
gmail in the browser, takes the avilable system memory below this. This
means that in 2gb devices the threshold is never met, and the browser
never runs more than one tab at the same time. this impacts user
experience, specially in desktop mode. For example is not possible to
open a document in the browser while attending a hangout.
How to reproduce
open a tab in the browser, go to youtube and play any video
then open a new tab
expected:
music/sound in the video continues to play
actual in m10:
sound stops playing shortly after opening the tab
