TomTom screen timeout?

Hi,
I have tomtom navigator 6 working fine on my tytn2 but after a few minuets the screen times out and goes black, u then have to press the power button for it to come back but it then looses the gps and u have to wait a few secs before it comes back.
Is there any way to leave screen on all the time for tomtom?
Thanks
Jason
Adjust your power settings.
But that will change it for everything and it will hurt my battery life. surley there must be a fix for this type of program or something?
Thanks
Jason
I have never had a problem with TomTom and screen timeout, I think I have seen some settings for it in TomTom itself...
My TT6 has worked just fine from day 1...not sure what I did, if anything to keep the screen on.
Already had a good look and there isnt any settings for it.
Are you sure you haven't set the safety settings on TomTom to turn off the screen over a certain speed?
From your description I don't think this is the case. Weird problem though, I don't get it on mine.
wierd issue, to add to this i keep getting the pin screen appear after about 15-20 mins when using TomTom, yes i do have the pin enabled and its set for 0mins so when the screen times out its on, but i have configured it to 5, 15 mins with the same effect, the sceen just reverts to pin after around 15-20mins (i have to have this enables as my work exchange requires (read force) it), which generally means i have to type in my set pin to get tomtom back.... not good.......

You have to look harder buddy. Run Tomtom then go to Change Preferences. In there, open Safety Preferences. Select Disable safety lock and tap Done. Then you will be presented with the next option: "Turn off map display". Set this to Never.

turning on the screen always takes me to today

Don't know if anyone has exerienced this but, everytime I turn the screen on the device shows the today screen, no matter what it's running. Not a big deal, but I used to turn off the screen for a few seconds when I wanted to take pictures in low light conditios and I can't do that anymore
It all began when I configured my exchange account and had to install Zenyee's Stayunlocked to avoid having to enter a password every 5 min (due to my company's security policies).
Anyone else has this problem?
thanks in advance

nope
nope. I already tried different settings there and it didn't change. I just noticed another funny thing. the screen turns on alone for a moment five seconds after I turn it off. but this only happens if I'm using the camera. Isn't it weird? It just flashes and turns off again....
any suggestions?
Anyone else has something to add to this issue? Has anybody else used zenyee Stayunlocked in a Kaiser?
thanks
Do you have Batterystatus installed? There is an option in the tool-tab:
"Show Today-Screen on WakeUp" Check if checked.

Blue line appears on screen when I swipe finger across it

Hey, I need help. My phone started acting up. There are a collection of 7 sets of digits on the top of the screen and when I swipe my finger across the screen it leaves a blue trail that only disappears when I tap it again. The digits have some thing to do with where the screen is being touched. Also, where ever I tap the screen a horizontal and vertical line appears and goes when I take my finger off. Anyone encountered this? Do I need to restore factory settings?
Thanks,
Brendan

go to settings>developer options and uncheck basically everything besides "allow debugging", if there is still an issue continue to settings>developer options>advanced and uncheck everything besides "show all animations"
im saying this all off memory so what you see might be slightly different from what im saying.

I must have hit it by accident. This started to happen after I had my phone connected to the laptop. Delighted, it has been annoying me for nearly 2 days.

Touchscreen Sensibility

I am noticing that when I Scroll through a webpage or android settings (really anything that involves scrolling), when I start the scrolling, the phone shows visual feedback as if I was just tapping, It does not tap, but it looks like I was tapping. Has anyone noticed this? Is as if I have to put my finger really strong on the phone to avoid this.
If Im not being totally clear, I can make a video.
I've notice some issues with low touchscreen sensitivity. You can see the value for yourself.
Activate developer options and check the 'pointer locations' check box. Then try to touch the screen as light as you can, don't swipt. See what your PRS number is at the top of the screen.
I get to 0.85 minimum

I've never noticed a lack of sensitivity. I did try your test though and can repeatedly get 0.77.

That's interesting, I get .85 only when really trying so more often than not it's 0.96+
What model and OS are you using?
I notice the touch screen mostly with the official YouTube app, if I drag down a video window and try to swipe it left to close it

I have tried this test. I can get .77 only once or twice, all of the other times were .85 or .88 . ¿Do we know what value we should be seeing? Is there a way to calibrate this? Can temperature affect this sensibility?

Screen flickering problem

Hi guys, suddenly i'm having this problem with my phone i'll let you the link to the video so you can see what i'm talking about- This is happenig just with the screen off when i missd the fingerprint or when i shut the phone off. I alrady tried other roms (i'm at xiaomi.eu stable) and flash it with miflash to global stable. The problem is always gone for a while after flashing but hours later even a day later it happend again and then never goes. It has to be hardware problem but i don't knoiw what could be, i don't want to replace de screen until i'm sure because once ii's unlocked with the screen on and i'm using it never shows a problem. I hope you can help me

Dang it. I'm experiencing the same issue for the past few days with my Global ver. Mi8.
Any solutions?
Any chance you installed "Dark Mod" or a similar MIUI Theme ?
It's probably a theme problem, had a similar bug when I installed a dark theme. Try restarting your device and then apply the default theme.
Just when I was about to go to the service centre, my phone becomes normal. How about you guys?
Have you try different rom?
Try to install custom kernel to resolve your screen flickering.

I have a similar problem. The screen, sometimes, when i try to turn it on, flashes and turn off again. When trying again it works.

This is exactly my problem, too. Did you solve it yet? I'm on newest global stable, no root and default theme.
Turn off auto brightness and turn upp brightness until it stop flickering.
You can try the app oled saver.
If the issue persists irregardless of brightness settings it's obviously a theme issue

im on screen flickering problem when phone going to sleep/lock
with your guide the flicker gone
thanks
The problem persists even though with oled saver installed. Is it software or hardware problem?
Hi
Can you try this
Go to Settings >> More Tab >> About device.
Find "Build number" and click 6 times fast on it.
You will then get the message saying: "You are now a developer"
Come back to Home Screen, and then go back to Settings >> More Tab >> Now you will see the "Developer Options"
Now go to Developer options >> Drawing Section or Rendering Section >> Find "Turn off hardware overlays" or "disable hardware overlays" >> This will force the phone to always use GPU for screen compositing

Did you install any custom miui theme?
My girlfriend had the same issue on her Mi 8, and it became so bad that the phone would just flicker and not show anything on the screen, even after restoring factory settings. She brought it to a Xiaomi service center, and after two weeks she got it back with no issues, the receipt they gave her mentioned a firmware update. Unfortunately, the phone came with an older MIUI version, and when it automatically updated to version 10.2.2 the flickering screen came back. We updated to 10.2.3 but the problem it still there. At least now the phone can be unlocked and used normally.
try this one
my mi 8 happened to have the same problem. it flickers every time I unlock and shut down my phone. I was about to repair it, but suddenly the flickers have gone. all I did was turn up the brightness somewhere around 50-70%. hope it helps!
dears, I have a worse variant of this problem: in my case, when the phone does not recognize the fingerprint. the screen blinks and then the phone turn off.
Have someone noticed that?
Here is the problem that i'm facing. Qlmost every time i plug my phone to the charger the screen start flickering, it even continue to flicker when i unplug it. Any advice?
