Would anyone else be curious in helping me compile a list of quirks for various devices/modems/chipsets for SCP? I've noticed that Mediatek chipsets seem to report more information than Qualcomm. I bought a cheap Moto G 5G 2024 and notice that it displays the LTE downlink bandwidth, and the NSA information of T-Mobile, something that my S22+, which is also Qualcomm, won't do. I'm hoping that we can convince either Google or OEMs to fix their reporting on various devices.
So far across all Qualcomm devices I've tested:
- NR neighbor cells don't report
- NR downlink or uplink bandwidth doesn't report (NR doesn't appear with CA as a result, only showing LTE)
- NR signal levels randomly stop updating for various period of time before continuing to update (affects CellMapper more)
- LTE CA levels randomly report and don't always update quickly when CA changes
On the S22:
- LTE Timing Advance (TA) doesn't work and always reports 0, reported issue to Samsung and waiting to hear back
On the Samsung Galaxy S series (USA - Qualcomm Snapdragon):
- LTE downlink or uplink bandwidth isn't reported
- T-Mobile NR NSA doesn't report band information, AT&T & Verizon work OK (n5 & n77 tested)
Definitely. There are still a handful of Sprint sites here that haven't been decommissioned yet but also haven't been upgraded yet and they're offline. I think T-Mobile really wants to keep them but for one reason or another is running into trouble.
