Changing channel settings is very slow!

[cherrie]

Hi,

Nexus 5 on RC; whenever I want to change channel settings it takes a very long time, sometimes it does not even work. There are 4 channels: development,edge,Release candidate and Stable. Why the different writing style?

Why is it so slow changing them?

In the /var/log/syslog I get those entries, while connected via mobile data (LTE):

Thanks for your answers!

Hi @cherrie

You need to be a bit more specific on what you call "a very long time" or "slow".
Switching channel requires to download the system image so it depends on your bandwidth... Also it requires a reboot in order to load the new version of the OS.

Some might find it "slow" when it's actually "normal"/"regular"/"standard"

@applee It is not about downloading the system image, but the "simple" process of changing channel say from RC to Stable or vice versa. It says Fetching channels, the circle rotates and after 3 minutes I get the following on the screen:
< Channels settings
Channel to get updates from:

underneath all empty, no selection

@cherrie When I go to Channels, after 1 or 2 seconds, it displays the channels to choose from. Meizu Pro 5, stable channel.

Not sure if this is relevant or helps, but hope so.
