Hey guys, First time poster but not exactly new here. I finally got around to Rooting my phone and replacing the ROM with CM7. I'm in love with CM7 and I haven't had any problems with it except for the Reception. The 3G and 4G seem to be duking it out for control over my phone and its killing my battery, at least think that's whats killing my battery. I tried to adjust the APN settings but it slightly worked the signal still alternating between 4g,3g, and Edge. Sometimes it seems that the 4G only kicks in when needed, but that was not the case because i was trying to browse the internet and it kept jumping around again and stopped on edge Im hardly getting any 4G . The Wifi is working fine though. Anyone else having this problem. Im sorry if im reposting anything >.> but i really have been looking for help for the past 2 days and have found nothing if there is a fix or patch can you point me in the right direction?
try flashing a new radio?
+1 for new radio. Over the past week I have been exploring different radio. I started with 12.28b.60.140e_26.03.02.26 which came with my phone, jumped to 12.52.60.25_26.08.04.30 which most people find to be best for them but this was worse for me (speed was significantly worse, signal slightly better), and finally tried the newest one, 12.56.60.25_26.10.04.03. For me the newest one is by far the best in terms of speed and signal. But of course which is best for you depends on your location and what not. For links and more information, check here http://forum.xda-developers.com/showthread.php?t=970809
Thanks hopefully this will solve my issue if i can figure it out.

What radio is everyone using or would recommend for CM7?
I can't post in the development forums yet even though i've been here awhile just a lurker though.
2.15.00.07.28 There is a newer one I believe but I haven't tried it.
This question wouldn't belong in the development forum anyways. Here or Q & A. That is exactly why they make people wait to post in there =)
Noticed a bit of a stronger signal when I flashed the 11.19 radio (newest). As I understand it all phones are different though, I would test each one and see what works best for you.

Yeah but i would have just posted in the CM7 thread, but i understand.
I have the 11.19 radio right now (flashed it and hboot 92 while running SR 3.5 athena and it killed my wifi...) seems to be doing fine. Took about 3 tries to get CM7 working correctly for me though. Kept getting a boot loop forcing me to reflash.
Give each radio a test drive yourself for a few days. Asking what radio you should use is like asking someone to tell you what your favorite color should be.
Baseband performance is extremely subjective based upon your individual variables. As such, someone else's experience isn't necessarily a reliable indicator of what you can expect on your own phone in your location.
I'm running 11.19 now on rooted 2.2 and I seem to be getting better signal now than I did before. I was at Camp Old Indian over the weekend and was getting 2 bars consistently while everyone else got "no service". Anyone in Scouting that knows the upstate area of South Carolina knows exactly what I'm talking about.
I'm using 7.28. I was using 11.19 for a about a month before going back. Cell reception is the same but 3g is faster on 7.28. Atleast for me it is. I never use gps so cant speak for that.
I just flashed 11.19 and I'll be trying it out for a few days. My work has some sort of issue inside the building -- there are "dead" places all over the building and it tends to eat my battery when I spend time in those areas. It's very predictable (on the old radio) so I'll know pretty quick if any difference has been made.
There is a thread in the development forums that is a must-read if you are considering a radio flash so you A)know what to do and B)don't permanently brick your phone.

The next time you have to reboot your phone, go ahead and pull the battery too. It might help to completely power down the device. It may not help, but it can't hurt.
i have been using the 11.19 radio for a couple of months and it works well for me.
Flashed 11.19 and things didn't seem any different in terms of call quality, battery life, or signal strength. I flashed the 9.xx version and it didn't seem any different, either. I'm going to put all three on the phone and record signal strength in the same place at the same time of the day and do various d/l speed tests and see if I can find a definitive radio that meets my needs. If anyone has any suggestions for a testing methodology, please let me know....

That sounds great actually. I am usin the new evo 4.08 radio n went from -85 on 11.10 to -78. All from my house, i tested right b4 i flashed new radio.

Ok, so I ran 10 trials each for the three kernels about 1 minute apart and measured dBm and kbps UL and DL speeds using speedtest from the market....
Having testing it and reflecting on the data, it's impossible to test meaningfully with just one phone.
The upload and download speeds vary too much from moment to moment and within an hour apart, 11.19 went from an average DL speed of 480kbps to 1150kbps. This is clearly just a function of who is currently sucking up bandwidth and unless I have three phones with the three versions of the radio side by side running the tests, I don't know how I can make it meaningful.
I did compare the dBm on each kernel and they were within -1 dBm of each other consistently. The phone was placed in the exact same location and I watched for changes in the number until the screen blanked. I then opened it again and monitored it again until it timed out and so on... 10 times for each radio version. The difference was so small it would have to be considered insignificant.

Flashed 4.08 about an hour ago. *228 afterward even though it has never made a difference locally. No difference. I place my phone in the EXACT same spot facing the exact same direction and monitor the dBm level. The best I've seen from that spot is -93 dBM and worst is -99dBm. Each radio has displayed that range and pinned right at -94 to -95.
I'm beginning to believe that the radio itself has a "fixed" send/receive strength and that no amount of software can change a hardware limitation. Maybe it can change rules like how long a GPS waits to lock based on number of acceptable satellite grabs or something like that, but I'm not seeing one bit of difference in radios.
The new 4.08 radio is working good for me.

As far as receiver sensitivity goes...I was an electronics technician at one time in my life, and I too believe the hardware is the limiting factor. E.g: My phone is setting in the exact same spot, facing the same direction, and I updated from 11.19 to 04.08, and only noticed -1db difference. I am using the Real Signal app. And it shows the relative strength of both signals that our CDMA phones use.
I am currently tethering over a 4g connection, and my internet is working fine, BUT I have a complete LOS for the cell signal. I think this could be a very important fact because we should be able to know some things by the fact that WiMax is working while the cell signal is altogether lost.
Hopefully, with this info, a solution is a little closer at hand.
Ok...when people say LOS do they mean Loss Of Service? Or Loss Of Signal?
Because if its the latter, that sht aint that bad. But if its the former...I'm glad I don't have it.

It is bad. People that get it have to reboot phone for it to come back and it kills battery life. Nit to mention missed calls and texts. It is a complete loss of service.

Its 2 separate radios..
I had pandora going over 4g earlier for hours...but lost signal with a crossed out circle after about an hour. Pandora kept going but u couldn't make a phone call, ths.falls in line with the other poster. Im running eg30plus over latest 2.1 midnight.

As WhiteWidows stated, it's 2 different radios. The LOS people have posted over and over about is the ability to make/receive calls (which is what the OP posted about). The Wimax radio (4G) doesn't transmit phone calls. That's why you can do data on 4G and still make a call at the same time.
.....
Hi guys, this is one of my first posts but I've been a long time reader coming from the Evo 4G forums. I'm rooter using Zedomax v3 and experienced multiple LOS as well.
Last night I tried limiting the clock speed to 1ghz and setting the min at 400mhz. Strangly I now get slightly better reception and never had a LOS yet. Will continue to test out this theory and see if it's clock speed related.
I came about testing this since I ran mine at 1.6 for a while and not only would I get more LOS occurances, I would also get phone freezes lol. I tether and stream music a lot so wanted to keep it slightly underclocked to keep the temps down. Hope this helps as a temporary band aid for the LOS bug
It definitely makes sense that the two radios are separate...the point of my post was just to offer some more information to help figure out a fix.
If one radio fails while the other stays working, do we know that the problem is phone-related? Many posters have speculated that the issue may be on Sprint's end, so I wasn't sure if this info did anything to challenge or support that theory. Maybe it does nothing, though -- just throwing it out there!
Someone posted a log cat of a LOS. There's still some coding in the radio files that thinks there is a sim card. Says sim disconnected and result radio off

Hopefully a solution is found soon, I've seen similar issues posted on various android forums. Androidforums, Sprint community and here. Wish I waited a bit to hear more user experiences....

Has anyone tried editing the build prop to manually change the preferred network from wcdma to CDMA auto? Maybe that'd fix that issue
I have been on my current SGS2 stock out of the box for over a week now and have not had any LOS issues, or missing texts, or data not working, or missing phone calls, etc.....
I have been using wi-fi, 4G, 3G, have an Airaive, went to an area where there is no Sprint service and phone roamed fine and then went back to Sprint service when available.
I have been unable to replicate the LOS issue on my current phone through all possible ways of using it.
My first SGS2 was also fine until I rooted it which then gave me an LOS within 12 hours of doing so.
If someone has a another sure way to get an LOS, I am willing to try it on my stock, never rooted phone but I don't think there are any other situations I can try that I haven't already......
Time.I have went 3 days without a los then 2 in same day.It is all random
So recently I've noticed that my 4g connection is dropping down to 3g a whole bunch when I'm in an area with very good coverage of 4g. I don't know of any issues related to this on any post I've searched for online so far. There might be one but haven't found it yet though. If anyone can give me some advice to this issue id appreciate it cause I'd love to utilize my phone as much as possible.
So, I've had my phone for probably about a year or maybe longer, Rooted it when I first got it, came from an Eris...I flashed a few different ROMs then kinda settled and have been out of it for quite some time now...
But I'm back...and I've got a question, back when I was flashing ROMs often, I couldn't find one that wouldn't drop network connections while using wifi/wifi tether.
Has this issue been resolved? It didn't seem like it was ever a really big issue with most, before, so when I asked about it months ago, no one said much, but I'm hoping now, with newer releases of ROMs someone will have some more info on this issue?
Thanks in advance...
p.s.
currently I'm running TSM Bullet Vivow 1.4 and haven't flashed anything for a good 8 months and I'm gettin buggy and wanna upgrade to something fancy, fast and doesn't drop service...
You need to get a update of your firmware
I'm still a newb on a lot of stuff...how do I go about doing that?
Just google
Are you referring to a radio update? Last I checked, that wasn't the issue and I tried different radios with no results
Kamikaze - I experienced this as well on Bullet, is it while you are on the phone and the call drops out for a few seconds? I think it has to do with the modified boot.img that the port uses.
This is a list of what worked without connection issues for me.
- Unoffical CM9 by Aeroevan
- Nitsuj's stock port for our phone
- Mikrunny (I think but cant remember)
Yeah, it is a problem with ROMs that are ported. The only ROM this doesn't happen on for me is Justin's stock/stock-modified ROM.
I always found that all ported ROMs worked for me because I had the latest OEM radio. But, when I had the leaked ROM for the DINC2 it said to update a radio but I didn't and the WiFi and data signals kept over writing reach other.
So, its just a thing with the radio.

My experience has been less than pleasant with my signal on my Inc2. I have been all over google trying to find a way to boost my signal for the Inc2. I have only had my Inc2 for a few months and just rooted a few weeks ago. Mine problem is not a result of having WiFi on/off, mine is just a week signal period (-95 dBm to -105 dBm). From what I found through my search is people modifying the back cover with foil/copper wire and tape, raising the cleaning the contacts for the antenna, which I have tried all of these as well. I am considering buying a new cover just to see if I can get a better signal as everything I have tried has failed to boost my signal. I have tried *22891 to update my PRL as well as toggling the settings from CDMA only PRL and CDMA/GSM PRL. If anyone finds the magic trick to boost signal strength I am open to other suggestions.

Then I don't have any advice for you. Do you get bad data speeds or drop calls, or is it just the numbers that bother you?

Data speeds are a bit slow but that is not really a problem as I connect to wifi most of the time. The major problem is I get grumbled voices a lot when the signal drops below -100 and I have to change rooms to continue the conversations, only a dropped call from time to time, but I get people telling me they tried to call me but my phone didn't ring and I think that is a result of the low signal strength. I think this is a hardware problem more so then a software/rom issue because a lot of people have an issue with low signal with the Inc2 I found searching on the Verizon forums. I do appreciate you taking time to inquire.

Looking for a lower number would prove challenging unless you are right next to a Verizon tower. I know this because at work we have one on premises and my signal goes to 40 to 60 dbm.
Of course, at home, my signal ranges from 85 to 105 dbm but experience no dropped calls.
Ever since I got my first verizon phone in 2001 the signal quality has mostly measured (on every phone) at approx 85 to 105.
And this is living in two metropolitan cities. I wouldnt give it that much thought unless you are dropping calls. Upgrading the radio is a good idea though as well as PRL after upgrading radio.
Edit: Just realized your post was answered. I would call Verizon and inform them of the call drops and ask them to log them. Could be your unit.

Which rom are you referring to exactly? Link to thread would be nice Thanks!
Yeah, just an update, nothing has cured the issue, updated both firmware and radio with the lastest leak ROM when it came out last month, then switched to different CM ROMs and those were horrible with the toggling of wifi hot spot signal and mobile network, so I went back to bullet and am just living with the random toggling off of wifi/network
I had been bouncing around on alot of the ICS rom's but couldn't seem to find one that this issue was gone. I think it is kernel related.
Since I want my phone to not have this issue I went back to GB for now which for me I didn't want to but this rom works just flawless for me.
GB Sense M 5.0.1 Ext4 Version w/ Drell's #21 Kernel w/ Sense 3 Patch v5.0
Was going to try cm7.2 next since I have always liked non-sense roms.
When i first got my Note 2, everything worked like a charm. But then, over the curse of a a week or so, the WiFi signal significantly decreased in strength. So much that it is basically unusable now, it can only be used when the phone is right next to the router - and what's the point then?
I donno what to do, i am thinking about returning the phone. But seriously, this can't be. WiFi works, it just has very, very bad reception. Any1 got suggestions? Or any ideas why it may have such bad reception? I have not dropped it or anything.
This is a serious problem for me, and i have not yet found a solution for this. I have even been contacted by other forum members, if i have found a solution yet, but i clearly have not - hence starting this thread.
Heeelp! :silly: :fingers-crossed:
