Greetings all, thanks for any help!
I got my Xperia Z4 LTE (US Version?) Tablet, after being a longtime owner of a Xperia Z2 LTE Tablet which I left on an airplane to never see again.
And now I'm on a replacement unit experiencing some odd behavior that I chalked up to being a defective unit, but getting the same behavior on the replacement.
My Z2 would always show full bars LTE here in Los Angeles, but the Z4 is showing LTE no-to-low bars sitting right next to my Tmobile LG G4 showing 4GLTE with full bars.
The weird thing is if I go into the About/Signal strength in the settings it shows practically the same signal strength (-dbm) on both my Tmobile LG G4 and the Xperia Z4.
If I do speed test and get similar results on both devices.
But, If I switch to WCDMA preferred I get full bars! Weird.
I tried the LTE Discovery app and discovered some interesting information about frequencies being used:
My TMobile LG G4 shows:
DL EARFCN 19500-2399
UL EARFCN 19950-20399
DL Freq: 2110mhz-2155mhz
UL Freq: 1710mhz-1755mhz
LTE BAND 4
My Xperia Z4 shows:
DL EARCFN: 2300
UL EARCFN: 20300
DL Freq: 2145.0mhz
UL Freq: 1745mhz
LTE BAND 4
It appears that the TMobile branded LG G4 is using a range of frequencies, and Xperia Z4 is locked on a single frequency, which may explain the low signal bars issue.
Can anyone confirm this? Is there a way to update the frequency ranges on the Xperia Z4 Tablet?
Anyone have an idea what I am seeing? Is this normal? I mean it seems to work ok, but I can't handle looking at my tablet with no to low signal strength!
Thanks all for viewing!
