Hi,
Please help, here are the sequence:
-
Got the glasses yesterday (my 2nd one) and used it on Galaxy Fold 3 (One UI 5.1 Android 13) and it works very well
-
At night, wanted to go for 120Hz so updated it and update was successful but the glasses responded so much slower and screen started going on/off at random intervals
https://www.reddit.com/r/Xreal/comments/14azqta/beta_testing_for_high_refresh_rate_firmware/
- Removed the app and then retry, same problem
Currently I have 3 phones and 2 Nreal glasses to which I will call
1st one : Nreal (the 1st one) and
2nd one : Air (the 2nd one since u guys rebranded) and the 2 phones are
-
Samsung Galaxy Fold 4
-
Samsung Galaxy Fold 3
-
Samsung Note 20
All of them are on Android 13 and One UI 5.1
Nreal + Galaxy Fold 4 works 100% no problem at all in the below set up
Since Fold 4 have the newest Nebula (the Beta one for 120Hz), it turns on and I can click Air Cast but then the picture kept turning on and off like its connected/disconnected (this is what I can see from the Nebula app)
Note 20 (no Nebula and no auto Dex) + Air
It takes a very long time for the picture to come up but is also turning on and off at intervals
Fold 3 (removed Nebula and turned off auto Dex) + Air
It shows the following on/off USB connection
So I figured it might be a firmware problem so I figure might be worth downgrading the Air from the 120Hz Beta version so I connected it to my Macbook to which when I switched on the Nebula App, it discovered the glass and started updating the firmware which is a good sign. While updating at 24%, the screen switched on and I was elated - Yay…then it switched off again and once finished updating, the screen continued to stay off…sigh…
So then I connected it back to my Fold 4 (Nebula 120Hz hoping that the Fold 4 but not turn connect to Nebula app so that it does not update the firmware back up again) but the result is just as bad, no picture…
So then I turn on the Nebula app (Fold 4 + Air) and then it started updating…but the result is that the phone stopped detecting it all together…
Along the way on the Fold 3 since its the worst impact since it appears the Fold 3 is most screwed, I also tried to clear data on the USB C and USB on the Fold 3 to no avail, the phone seems not detecting any glasses at all even with Nreal (but not with Nebula app turned on since I don’t want the Nebula app to screw up the Nreal glass on top of the already screwed Air). Will probably end up factory resetting the Fold 3 just to figure cuz we tried every possible combination.
Note 20 with Nreal - works perfect
Macbook with Nreal - haven’t tried cuz it would then downgrade the firmware on the Nreal back down from the 120Hz version
The last thing I wanted to try was to go to the website and do the proper firmware update to the glass so I went here: XREAL Air - Firmware update and
here is the result… all successful…the glasses showed the screen during 10% or something of the firmware update, yay!! but then turned off and never turned on the screen again…
So after the update:
Note 20 (no Nebula) + Air : Connected, no display
Fold 3 (no Nebula) + Air : Nothing…no detection, no display
Macbook (Nebula) + Air : Didn’t try cuz then it would change the firmware again
Fold 4 (Nebula 120Hz) + Air : Didn’t try cuz then it would change the firmware again
I think I must have lost 20 hours of sleep trying to get the glass working…Any ideas?
