GNSS Issues Screen issues

My L.S. and at least one other I know of are behaving erratically in the same way. My satellite icon flashes red, after a while corrects itself plays the boot up audio and tracks everything but GPS.
It will go red again, correct itself and then play the boot up audio again. Will keep doing this.
Rapid screen changes and screen freezes are common requiring recalibration frequently. (happened before migration too)
This is happening using an RTN or my T2 and radio.
Anyone else having these issues?

Sounds a LOT like what I've had going on the last two weeks with the newest LS I have - which is now in the process of being replaced. It kept "losing" it's authorization file or something strange and keep "playing the tune" every minute or so. The screen continually clicked away like crazy into different screens as well.
I did a factory recovery on mine back to Windows OS and it worked ok for a while, but when I went back to Linux it went back to behaving erratically.
Eugene has been helping/following my issue, you may check with him although I read in another thread he's on vacation....

This is a known issue in Linux and some changes were made in the Testing branch to try to fix this. If it happens rebooting should fix it.

Matt;
I tried all of that yesterday in the field, cleared the T2 NVRAM but still no GPS satellites and the screen freezes. I even force updated all the software this morning.
One other thing I noticed is my battery indicator was not showing time on a few occasions that the GNSS icon was flashing Red.
At present everything seems normal except I still am not tracking GPS in an open sky. Hope it gets resolved soon, I am sure it will.

Tracking of some signals is probably disabled in your settings. Check Advanced Setup (press Setup hardware button twice) > GNSS > Systems & Signals Tracking. Make sure all GPS signals are enabled:

Have you had Linux OS version 4.4.110.28 when having all these problems? It has some improvements that are suppose to help with the touch screen calibration:

Matt yes that is my version. This may help, after the migration I performed 2 new surveys using the local RTN where I set up new projects.
I had no issues on those except for maybe a screen freeze or 2.
My most recent project that I am having the issues with, I opened a project from last year to perform a survey on the other side of the road.
I merely opened up that project and started adding to it. The first day I used the RTN for a few measurements with no issues.
On the second day I wanted to use Hybrid RTK so I set up my T2 and radio and started working. I started having issues after about an 2.5 hours with the flashing GNSS icon
and lack of satellites.
I went back to the base, stopped it downloaded the file, cleared the NVRAM and started another base session but still had the issues.
Today I am not tracking GPS. I opened the 2 new projects after the migration thinking an old project file may be the cause and still have no GPS tracking.
The GNSS icon is no longer flashing however. Maybe using old projects before migration are causing a problem in the L.S.???

No, these issues are not related to a project. These are some issues popping up the the Linux OS that need resolved. Did you check to make sure your LS is configured to track all GPS signals?

My systems and signals tracking is set to Conventional. My system is on RAMS right now if you have time to take a look.

I don't see it on RAMS at the moment. If some signals have been disabled those boxes will be grey in the screen I posted above.

I had P2 turned off on mine the other day. I had not gone in and done anything with that screen so I’m not sure how it got that way. I will tell you that it made a huge difference in the ability to get a fix.

Same here I never touched those settings. Works great now.

I had very few unwanted screen clicks and freezes with the latest updates until I worked in this latest heat and sun.
Beginning to wonder if the heat has an effect on the screen? any one else?
