Hi, everyone.

Could someone help me with the signal strength issue I'm having with one of my phones.

I currently have two I605.
One (white) is rooted with unlocked bootloader with latest CM11
The other (Grey) is rooted with locked bootloader on stock MJ9. (4.3)

I'm using both on Lycamobile on Tmobile network.

The white one is working well with the Lycamobile.
The signal strength is -69 dBm with 22 asu on HSADPA.
I see the network as Lycamobile.

However, my grey phone's signal strength is bad.
It's -90 dBM with 11 asu on HSPA.
THe network is listed as T-mobile on this phone.

The APN settings are exactly same.
The phones are next to each other in the same house.
I have never had problem with the WHITE one any where,
but the GREY one won't connect to the network intermittently
because of weak signal strength outside. I'm not talking about the data.
The phone simply doesn't call or receive calls.

I'm wondering if there's a setting that I should be touching additionally
to unleash or unlock more bands in this GREY phone.

I'd appreciate any insight.
Thanks.

Aosp roms more accurately read the signal strength. The tw rom is reading lower but it just not as accurate at displaying the correct signal strength. It is strictly visual though. This is perfectly normal. Neither phone has to something wrong with it.

Hey, Thanks for the reply.

I'm not talking about the signal antenna icon.
I know that one is strictly for visual. Some shows Full Bar even when it's -100 while some shows 2 bars for the same condition.

Are you saying that even the signal strength reading in dBm is strictly visual as well?
Because I used various signal strength apps and they all show poor strengths in the "poor" note 2.

And I'm curious why there's a discrepancy of showing HSPA vs HSDPA, and Tmobile vs Lycamobile
when I'm using same phone, same cell tower, same service.

Yes it's visual in there as well. Aosp is supposed to read more accurately.I just heard time and time again not to focus so much on those numbers as tw has just as good of signal strength as aosp it just doesn't look like it visually.
