WCDMA cells get rscp null values in Samsung devices #35

Closed daviddagan closed 2 years ago

daviddagan commented 2 years ago

First, let me thank you guys for this wonderful project. really saved my life.

Second, I'm trying to extract WCDMA info from my Samsung devices (galaxy s21 ultra 5g, galaxy A22). and I get a lot of RSCP null values from the primary and secondary cells. if I install the app on Huawei phones I get much better RSCP and RSSI values.

can you please tell me why it is like this or even better which device will bring me the most accurate data in all the technologies?? (WCDMA, LTE, 5G)

thanks in advance, david

Is it related to the fact that devices pull out both UMTS and HSPA as WCDMA?

This behaviour is device-specific. Android APIs just define what sort of data can be provided. Unfortunately not all indicators are supported on all devices. Also the overall quality differs from device to device. So if you see RSCP on some Samsung phone, you might not see it on the other from the same manufacturer.
