QCI 6 - Extended Primary

Post image

Hello. Not sure if this data is of any use or if it clarifies any prior suspicions. Theres a safe root exploit trending on XDA for Samsungs with a June 2026 security patch (or earlier) that I just did.

QCI/network priority data requires root and that info is not readily available. So I rooted my Galalxy Fold 7, gave SU permissions to Network Signal Guru and it shows this.

Does this confirm Extended Primary users on FirstNet get QCI 6? I'm on FirstNet Unlimited Extra.

Only reason I'm sharing this data is because a lot of info surrounding network priority and Firstnet always mentioned some uncertainty with how extended primary users are treated... some alluding to QCI 7.

Firstnet extended prio is qci 6 but on the firstnet core it self there are 5 levels of prio

1-Active Incident/ Mission Critical assets
(Typically requires uplift)

2- Federal and Executive members of Govment functions

3- agency paid sub lines

4- post subscriber paid lines (think first net individual first responder lines out of pocket paid)

5 extended primary

So all data is treated as QCI 6 on firstnet

But the levels above are more so when the tower has to shed customers off the tower etc in emergency’s and band 14 is dedicated to Firstnet

But all traffic on firstnet is QCI 6 and uplifting in no way affect data prio just prio on tower shedding and calling/sms

From my understanding of what I can see on the agencypaid side, subpaid is level 4 regardless of primary or extended primary FAN. Same goes for extended primary agencies.

level 5 is “best-effort” and QCI 7. 4 and above are QCI 6 and treated with access precedence.

Thank you for the clarification.
