Help Full brightness when plugged in? Any suggestions?

[DeadlyFoez]

I use my phone in my car often as my means of listening to music and for the GPS. I hate the fact that the phone will time out and dim the screen. I have downloaded an app called "Full Brightness When Plugged In", and although it worked great on my old Optimus M, it is not working as it should on this phone.

Does anyone know of another way or app that can successfully do what I want?

Thank you.

Have you checked "Stay Awake" in Developer options?
There are also app-specific settings in some apps to keep the screen on.

Settings - Display - Screen Timeout - Never.

Have you tried that?

Settings - Display - Screen Timeout - Never.

That will keep the screen on all the time even when on battery, unless manually turned off with the power button. I doubt he wants that.

 

[DeadlyFoez]

Yes, I have tried the "Stay Awake", and I have tried putting the screen time out to "Never", but it makes the screen stay on all the time. I have not found anything that does exactly what I want it to do on this phone.

 

[Murf1]

I guess I don't understand. I thought when you have your phone plugged into power in your car that you wanted the screen to stay on at all times.

He does, but changing that setting as you posted will make the screen stay on at ALL times, whether on power or battery.
Foez, have you looked at Tasker or similar apps?

OK, then he can create a simple toggle widget for the screen timeout. Then just switch it when entering the car.

Could you please explain a little more. I don't have any widgets preinstalled on this phone that I can find that will accomplish what you are saying. Do you have any specific widgets in mind?

Power toggles.

Just remove the ones you don't want and add the wake lock widget, or the screen timeout one. It has some nice features like notification toggles and color and transparency options.

 

[Fox Mulder]

+1 for Power Toggles, it's a great app.

 

[DeadlyFoez]

Awesome. Thank you very much. This will work our really well. Too bad that other app wasn't working for me, but oh well.

I have the same request/complaint as the OP.

"Full Brightness When Plugged In"

Does the Power Toggles widget actually do that? I mean, with Power Toggles installed, does the act of plugging in the charger actually cause it to switch to a "full brightness always" mode? Or does it require pressing a button?

Also, I've noticed that even with Screen Dim set to "never" in the stock phone display settings, although the screen does stay on, it dims slightly after a period of time. This is really annoying. Has anyone else noticed that?

 

[Murf1]

Yes, I have noticed the screen slight dim that you mentioned. I think it does that for a few seconds right before the screen turns off (at what ever turn off interval you have set) to let you know it is about to turn off.

 

[toronado455]

I think I figured out what is going on. When using GPS, the screen dims to 76% and wont let you increase it to full brightness. If you attempt to increase the brightness, a message is displayed that says that the screen is dimmed due to temperature increase reasons. This is really pretty bad.

Mine does this as well, usually when plugged in and streaming in the car. It's not just the GPS.
Sometimes it happens after a very short time and the phone doesn't feel warm at all, so I'm thinking the "overheat" detection is a bit erroneous and maybe a parameter is set incorrectly. No idea how to find or fix it though.

I've also noticed, as did you, that it is not just with GPS. Short time and phone not physically warm. Still no fix for this problem?

 

[Fox Mulder]

Sorry meant to reply sooner-
I did find a setting in the hidden menu for "Overtemp property" and set it to "off" hoping it would stop this from happening. Unfortunately it didn't make any difference and I haven't come across any solution. .
I have Tasker set to up the brightness when plugged into USB with Bluetooth on, so when it dims itself in the car I just unplug the charger from the socket and plug it back in and Tasker makes it go bright again. It's annoying but the phone is great otherwise so I deal with it.

all you need is 'stay awake' under developer options. this only affects when plugged in. if it isn't working that way for you then you have some app installed that is messing with it...

 

[Fox Mulder]

Nope already have that checked.
This is the phone thinking it's overheating and dropping the brightness, nothing to do with any apps.

you can disable it by modifying thermald.conf

 

[Fox Mulder]

Modifying it how?

look at the file. its pretty easy to understand.

I get an idea of what it does but it's not intuitive as far as what to change. Also there are several versions of the file, how to tell which is active (or are they all active?).
Would simply removing the "+lcd" from the list of actions, wherever it appears, disable the dimming without changing anything else? That would be the goal here, either that or raise the temp threshold so it only happens when the phone really overheats.

thermald. conf is a link to the correct file in use. if you turn off thermal management in the hidden menu and reboot I think you'd get the same effect. - or link thermald.conf to the empty one.
