Incorrect band for 5G NR (NSA) #56

Closed Ahmad-Amsyar closed 3 months ago

Ahmad-Amsyar commented 4 months ago

Describe the bug The band for 5G NR show as n77 when in Malaysia, we only use n78 as 5G band and B28 as anchor band.

To Reproduce 1) Enable 5G. 2) Open SignalCheck app. 3) 4G anchor band shown correctly but 5G band is wrong.

Expected behavior 4G anchor band shown as B28 and 5G is shown as N78.

Device details

Additional context Malaysia is using single wholesale network (Digital Nasional) for 5G. Which means all telco in Malaysia use the same band for 5G NSA.

Other app such as NetMonster and G-Nettrack doesn't seems to have this problem.

Thank you for this report. Unfortunately there are many issues with the native Android methods to identify 5G-NR bands. In cases where a particular frequency is part of multiple bands (n77 and n78 in your case), the OS reports the lowest one. I will implement a workaround in the next app update.
