On my LilyGo T-Deck (the simple one indeed).

Having used version 0.9.12 with maps in the directory /tiles i got a beautiful map displayed.

Now - and with the same untouched sd-card - with the version 0.9.12.3 I only get a blank screen, with the blue lines, evt the zoomlevel and a repeater in the vicinity, but no map at all...

I am quite sure the SD card is not to blame and that the structure of the png files (z/x/y.png) is correct.

I think this is the same as #292.

Test: Change Mgmt → Global → Primary Disk to "SD Card" and see if it then works. (Make a backup of at least your private key before.)

But you don't have an almost locked-up device when you are in the map screen?

I did the change to SD Card - and everything works flawlessly now...
And btw my program didn't lock-up on a blank screen although there was a 'certain' lag on the touch screen...
Thanks!
