[Q] HSPA -> LTE switching time - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

Hey all - working with a Telus i747m running CM10.
I've noticed that when the phone detects an LTE signal, there's a noticeable period of no signal between dropping the HSPA signal and starting to use the LTE signal. Is this normal behaviour with your network? (It makes sense to me - the phone would need to switch radios, after all.)
Thanks in advance for your feedback.

Odd 4G LTE/3G Behavior after upgrading to leaked 4.0.3 radios

I flashed the leaked 4.0.3 radios for my Nexus, and noticed a good boost in signal strength. However, I have had several occurrences of not being able to switch back to CDMA signal. If I set is to CDMA only in the settings, I get no data connection. If I switch it back to CDMA/LTE, data will come back instantly. Also, while downloading a large file to my Mac, using WiFi Tether on the 4G network, I received a phone call. I expected my data connection to either disappear, or default to 1x, but instead, I maintained 4 bars of LTE signal, and my download continued at a fast speed throughout the duration of my 5+ minute phone call. I thought this was only possible with VoLTE, which Verizon hasn't launched yet? Any clarification on these matters would be greatly appreciated!

You should be able to maintain LTE data and use voice at the same time, VoLTE or no VoLTE. In the non-VoLTE environment, the GN uses both CDMA and LTE radios concurrently and one doesn't impact the other. Only when using CDMA data will your data session be cut by a call.

3g signal issue

So here is my grudge as of now with the gnex. When I go from roaming to 3g or airplane to 3g, it takes an unbelievably long time to actually GET the 3g signal. It will show me that I have 3 or 4 bars of service but does not show me the little 3g icon. I am currently running Sourcery 3.2 as my rom and have my mobile network set to CDMA only. Is this a common issue or do I have a possible shotty gnex?

3g signal: ICS vs IOS5

Is it possible that the iphone 5 has better 3g reception than our arc(s)?
This is especially noticeable indoor, my friends iphone 5 can download at 800kbps where my arc has difficulties even connecting with the 3g network on the exact location and time and carrier, so it forces me to download over 2g and even this is slower than average(5 kbps).
Also when in settings i choose (3g(preferred) / 2g) my phone is a lot of the time without signal, so the switch to 2g isn't working that good. Often calls from friends are directed immediately to voicemail. Sometimes when my phones comes out of standby, then it connects to 2g, so the rest of the time it was constantly without signal.... frustrating! That's why I put it most of the time on 2g only.
Yes i've got the correct carrier apn settings. (outdoor my 3g can download @ > 1500kpbs)
same issue on different basebands, first on 77 now on 83, no difference there.
not rom related: first on jj'shybrid now on uhd 2.0.3 (locked BL).
Someone with the same issue?
You know what will be a good solution if the setting would be "2g(preffered) / 3g", so only when mobile data is switched on and a decent 3g connection is found it would switch to 3g and the rest of the time it would stay on 2g. This is probably kernel related, but does custom kernels have this feature?
Thanks
Yes. Lol
IPhone is newer.

iPhone might have stronger antenna than Xperia phones.
ROMs have nothing to do with it. If your phone is rooted, you could try using some 3G improvement tweaks.

Tab T315 Reception Issues

Hello everyone,
I am using the T315 as a phone and am having problems with reception. I notice that if I have network mode to GSM/WCDMA (auto connect) I get better reception and more bars. If I switch to LTE/GSM/WCDMA(auto connect) my internet is faster but I do not get as many bars and the reception is not as good. Any idea on how I can resolve this? I want to use LTE all the time but not if the reception is bad.
BTW I am using the stock ROM 4.2.2
Thanks in advance!

LTE connectivity issues, "3107" 3G network

Hi everyone,
My M9 has been having consistent issues with LTE connectivity. I'm rooted, s-off. The issue I'm having is that I regularly only connect to the 3G network, and my phone labels it simply as "3107". In the network list, I'm often connected to the Verizon Tracfone network, not the full vzwinternet network. If I manually switch these, it only lasts a short amount of time and LTE connectivity is weak. I've re-flashed a stock rom, same issue. New sim card even, same issue.
Any suggestions on how I can see exactly what bands are on/off and if my baseband firmware is out of date and/or broken - and if so - where I can get the latest version to try and fix it?
Thanks
