Hello,

We are receiving several complaints from customers that the inactive backlight intensity on the T46 is too dim. They are reporting to us that they think the phone is "broken" because the screen keeps "turning off" that they have to shake the phone to get it to "wake up". We don't want to have the screen actually turn off on inactivity, but we also don't want the backlight to remain at full intensity during periods of inactivity. If there is a way that the inactive brightness intensity can be raised slightly in a new firmware update or if we can be given the ability to choose what is bright enough to our customers for the inactive brightness, that would be even better. Unfortunately, our only option right now is to configure all the screens to never turn off, so they are literally 24x7x365 at brightness level 8 to keep our customers happy and to ensure to them that the T46 phones aren't "broken".


Best,

J

Hi jc11686,


You can choose "inactive backlight" as low. 28.72.0.1 has this setting. What is your T46G's firmware now?

We are already using 28.72.0.1. The problem is the low setting is so low that everybody thinks the screen is going bad because they can't see anything on the display. I tell them to press a button on the phone, but they still dislike the idea of needing to press a button anytime they want to check if they missed a call, have a new voicemail, or just check the time. This is where I was thinking it would be much better if we had the ability to choose how bright low is, like at 4 or 5.

I think you can choose the brightness level 4 or 5 instead.

This is what worked for me.


This will make the phone display dim to level 7 after 30 seconds.

Note that the longer you leave your display on, the shorter life span it will have. Not sure what the MTBF of the display on the T46 is. Would be interesting to find that out.

Furthermore:
phone_setting.active_backlight_level
It configures the level of the active backlight intensity. For SIP-T28P IP phones and the connected EXP39: The default value is 2. For SIP-T46G IP phones and the connected EXP40: The default value is 8

The goal of the OP was to adjust the inactive backlight level...

Actually, you can do this by setting "phone_setting.inactive_backlight_level" to a value >1, e.g.
Even if the Autoprovisioning Guide tells you there are only 0 and 1 as available values, I found 3 or 4 most useful.

MTBF = Mean Time Between Failure
The MTBF to all Yealink phones is 50,000 hours.
