Hi @jrobin28260,
I have encountered another problem with LTE (4G) that may be related to the problem you reported.
I have connected an HDMI screen using the official USB-C dock of the convergence package or a third party Anker USB-C dock.
When I use the LTE connection actively, for example downloading a web page on LTE data or doing a speed test, the HDMI screen becomes black for a few seconds.
The screen comes back shortly after but becomes black again on the next LTE data activity.
I verified that this issue does not happen if I select 3G only data connection, so this only happens with 4G LTE connection.
I reproduced the issue with both my Braveheart and postmarketOS edition PinePhones, and a braveheart of a friend of mine.
The Braveheart had the CC hardware fix to make HDMI output work.
Note: I was using postmarketOS with Phosh as O.S. but the problem happens also with Mobian
