I would like to open discussion on developing a permanent fix for the horrible bug with Android 2.1 CDMA devices defaulting to a Preferred Network of GSM. My goal will be to develop a script or app that will either run at boot, via a cronjob, or as an icon/widget on the homescreen that will set the Preferred Network to CDMA.
The "Testing" app (*#*#4636#*#*) looks to be /system/bin/iqd. I have used strace to capture what the process is doing when the Preferred Network is properly set to CDMA, but I could not decipher it (didn't see any I/O on any files, only RAM). I've attached my log in case someone else can make sense of it.
This is the #1 issue on my Evo, and the only thing I have done to notice any change in battery life, and the difference is absolutely huge. Without applying this fix after EVERY reboot, I only get 4 hours max out of my phone. After applying the fix, I get 8-12 hours, which is actually reasonable. This desperately needs a permanent fix, and I can't imagine I am alone here.
Cheers!
This seems like a great idea.
I just checked my phone, it's set to CDMA auto. I am running fully stock, but rooted and unlocked.

I just checked as well and this does not seem to be an issue with me. Mine is already set to CDMA(Auto). I have fresh installed and I also checked on my brothers stock Evo.
Actually I think everyone is affected by this problem.
Go to *#*#4636#*#* , phone info, and you will see that it says CDMA.
So far so good. Now, hit menu and then choose select radio band. and you will see a force close,don't panic now you will be back at the menu, hit phone information again and you will see that now it says GSM! choose cdma and hit back, done.
Now, I'm not sure if that actually does anything for battery life, as the phone doesn't even have a GSM radio. I think its just a pointless HTC bug from the hero days since android did not have native cdma, so HTC had to hack it in.
The purpose of this thread is not to determine whether or not you are affected by the bug. There are tons of other threads discussing that. If your "Time without Signal" value is excessively high (usually around 50%), you are affected, and are only getting about half of the potential battery life from your device (for Evos, it makes the device nearly non-functional because it won't last through a day. A friend also confirmed this on his Incredible, and now gets 2 days out of his battery instead of 1).
Let's limit this thread to only those who are affected by the issue and those looking for a solution. Thanks!
Now, has anyone taken a look at my strace log? Or does anyone have any idea where/how the phone's radio values are set? I noticed some references to "ciq-backend," perhaps this is a deamon, service, or command that we could tap into. Any ideas?

It absolutely has a huge affect on my battery as well as two of my friends' Evos (two are 0002, one is 0003), although I can't speak for all Evo owners. We all experience the same 4-5 hours battery life without the fix, and 8-12 hours with the fix applied. It's just such a pain in the butt to do it EVERY time the phone reboots.
well, its not the fix you are looking for, BUT, i have found that it makes changing this after a reboot MUCH easier.
Download an app called simply "network" from the market.
It gets you right into the test menu, and then you can hit select radio band and complete the process from there.
I think this should be something that could be built into roms but not sure... Also.. i am still not sure that by do doing hte select radio and getting the FC, that THIS isnt what is causing use to see it come up as GSM. No proof of that other than just the thought, but it could be like a default that after the FC causes to revert to (but i did notice better batter life after it than before and its something i have dont on every rom every time i reboot since it was discoverd.
Hope the network app helps a little until there is a permanent solution!
Thanks for noticing this.
I am having the same issue and i have HORRIBLE battery life. Im getting close to my 30 days and might want to switch this evo in for a newer one, but I dont want to lose root.
If i can get some more battery life out of this... I might just be a little happier.
I get like 12-15 without the fix and moderate usage and wifi/GPS on all the time (no 4g tho), but I tried changing it and we'll find out if it's any better.
4-5 hours has to be an exaggeration unless it's something to do with 4g :\
Its a big bug on htc phones and it will say cdma but its really on gsm.. some roms will get a "time without signal" which does drain a ton off battery cuz the phone is looking for a gsm network constantly and in a sense is roaming on cdma. We just dont see anything to do with roaming cuz its suppose to be our defaulted network.
Also we dont have a full gsm radio but we can connect to gsm networks.

We can connect to GSM networks on this phone? I am confused, where have I been lol?
No these phones cannot be used on gsm.
Yes I do see that now after I hit the menu and selected the band and it does seem to be an issue. My time without signal is around 45% which is insane considering I've had full bars all day. If we can figure some way to auto set this it would be great.

Wcdma is a gsm network setting. You want to use cdma only or cdma (prl).

Hi there,
I'm using Revolution HD 3.6.1 with its radio and relative RIL (which becomes with the rom by default). Obviously I have S-OFFed and rooted.
I'm experiencing some hiccups in 3G data connections. I don't know if it's due to the carrier (Wind Italia) or something in the phone (maybe the radio doesn't support it at all?). I'm in Europe, precisely in Italy.
Maybe should use an european version of radio? Or what?
In detail:
I activate data connection. The phone shows 3G before, and quickly goes in H (HDSPA). Then I use many apps that needs internet connection. Within a short time it goes again in 3G and i have absolutely NO data connections. After a delay of 5-10 sec it goes again in HDSPA and everything works. When it goes again in 3G i have no data, then again H and data working.
What's the problem?
EDIT: Problem solved! See in this post.
P.s.: Sorry for my bad english
I was going to ask about something similar to this, so rather than start a thread I will post it here. I too am running the 3.6.1 with its radio, S-OFF, & rooted.
What I am seeing on boot up is the standard progressive upgrades of data networks (just bars, then 2G, then 3G, finally H). The H only stays for a few seconds then drops to 3G and basically stays like that. However, as soon as I open an internet requiring application, it jumps to show H and typically stays that way as long as a data connection is active. My Speed Test results show its 4G speeds (same as stock ROM and radio) when its showing the H, so obviously its working, I'm just wondering if its intentional that the display only shows 3G? Or maybe its set so the ROM "relaxes" on 3G, but switches to 4G when data is actually being sent/received?
~T.J.
Maybe you used to have a 'background' app updating constantly.
The G, 3G and H usually depends on the signal in your area, the H is usually for high data transfer. If you're not using the internet,downloading anything or updating anything on your phone, then why would you need it on all the time?
3g is usually the norm, so I wouldn't worry!
For my issue, my stock ROM showed me what was available in the areas as I moved around, including showing 4G all the time if I was in a coverage area (which pretty much everywhere around me is). If I moved out of the 4G area for instance, it would drop to show me 3G.
This one just shows 3G all the time, even when I'm in areas I KNOW are 4G; UNTIL I use the data connection, then it switches and shows the H. I know its silly, but I liked actually gauging my providers service by being able to see what kinds of connections were available in various areas.
The fact I have to actually open the browser or run a speed test to see if 4G (H in this case) is available in that area is a little odd to me, why doesn't it just show the connection that's available?
~T.J.
Guys, I found a solution to my problem, googling around. That's awesome.
FYI I'll post here:
1. dial *#*#4636#*#*
2. Go to phone information
3. Toggle ciphering so it's off
4. Turn off radio
5. Turn on radio
6. Toggle ciphering back on
It seems to be working to me. An half hour without hiccups till now.
I have had this problem ever since my hd2 two years ago. I thought it was normal. I'm about to try the fix. If it fixes it you are a life saver.

Aww man same thing. Maybe its supposed to be like this.
Basically for me its for example on the xda app when ill refresh something it will always say processing as soon as the 3g symbol turns to h with both arrows on simutaneously.
Maybe that's how its supposed to be idk.

Only a brief temp fix? Are you sure?
I'm not having the same problem as before, now. I hope it remains still as it is.
I noticed that a lot of the time my SIM network is constantly switching between 3G and H.
I've got the latest Bugless Beast installed, along with Simple kernel 1.20.
Sounds like a radio deal. When idling, it should be on 3G. When data is being transferred, it'll switch over to H.

So how do I fix it? Do I have to flash another radio, is that it? If so, where can I get those?
Never messed with the radios, so I don't even know what to search for...

Make sure you follow directions and flash the appropriate one for your carrier. I've never had an issue like yours so I can't say for sure if this will solve it.
Sent by pocket technology.
My understanding is that this is completely normal and working as it should.
The changing between 3g and H icons is not an indication of switching networks but just letting you know that data is flowing to and/or from your device.
i.e. when your 3G/HSPA data is idle your device will indicate "3G" and switch to "H" when it's in use.

KiNG OMaR said:
Switching between 3G and H is a feature of CM. It saves on battery as a 4G signal uses up more juice than 3G. You automatically switch to H when you need a faster connection but then will change back to 3G when you don't.

AT&T customer, midwest United States here. I live in a fringe area, but have always been able to get reception.... until I rooted and started running custom ROMS. It seems some ROMS, for whatever reason, get better radio reception than others.
I tried Viper, and while it was the best for reception, there were a lot of things that gave me trouble and I couldnt live with.
The CM ROMS wont even think about getting reception for me, unless the mobile data is turned on, and then are very erratic. I leave the data turned off when at home due to it always looking and searching and killing my battery. Well, that, and I always use wifi at home. I even tried the newer 3.18 AT&T radio, but it didnt help
Any suggestions as to a ROM that is known for reception? Or a specific AT&T Radio that is better for reception? While I knew different ROMS had different good/bad points... I didnt know the reception was on of those things.
Thanks

There sure is a big difference for some reason, with me anyway. The only 2 radios I have found in the Radio thread for AT&T without the RIL (senseless ROMS) is the 2.20 and 3.18 radios. I have bounced back and forth between them, and not seen any difference to speak of. The 3.18 seems to be the more erratic of the 2, for me anyway

My advice would be to try a different radio until you get one that works for you. I work out of state so I have to change settings to wcdma only to make them work in the area. I use the 3.18 radios on both CM and Sense because they work best in my home area. Viper is based on 3.17.661.2 so AT&T 2.20 may be the best option to try.
I use 2.41 seems 80% of the others I've tried plain suck in my area

When flashing radios for CM, also be sure that you are flashing the ones designated strictly for CM as the radio fw is kept in another partition than sense. I've never had an issue finding a radio that works for me. They don't all work well but at least 1 always does. When looking for the best radio, I download them all, test them one at a time, marking the signal strength and speedtest results for each and then flash back to the radio that gave me the best results.

Im getting the radios out of the radio thread here on XDA. I am d/l the radios in the lower section, for CM. I didnt try a different radio when using Viper, because it was useless seeing as I had so many other issues. I wasnt aware I could use Vodaphone or Telstra radios, on AT&T. I had only tried the 2 AT&T radios. My bad, I will try the others.thanks for the info guys. The speed tests are a moot point for me. As I said, i am in a fringe area. I cant judge anything based on data speed, and leave data turned off most of the time. Im not worried about data speed, or trying to fix anything in that area. Im trying to get my phone to get good enough reception to make/receive calls dependably and send/receive texts dependably. Sorry if there was some confusion over this.
Honestly, I would have stuck with Viper, but my wifi wouldnt work, and I couldnt even get my contacts and calendar imported from my Google account. In fact, there wasnt even a Sync option for contacts. So that was a no go.
Thanks again

Ok, I tried just about every radio in my CM ROM, to no avail. Then, on a whim, I ticked "2G Networks Only", and now I have decent phone signal/reception. This sucks though.... to have my data connection have such an affect on my voice signal. I had always left my data turned off when at home, due to being in a fringe area, and it always bouncing around and killing my battery. That, and I always use wifi at home. Now, I have to leave my data turned on, and in 2G mode... just to be able to make a call. Rather silly to me.
Thanks to everyone who offered to help... MUCH appreciated
P.S. when it was said and done, I think I wound up back on the stock radio for Cory's CM ROM (2.20?)

signal remains the same... around -87/13, but the Edge "E" icon, disappears from the screen. So, no real difference that I can tell.
It just amazes me that my data connection/type/settings can ruin my voice reception. Hopefully, its going to work decently now.

thank you! so far, so good! As long as I leave the phone in 2G only, my signal is great. Well, great for my area anyway lol.
With VoLTE being so far out yet, and AT&T not having true 4G, and voice/data being on 2 different frequencies.... how in the world is this happening on this phone? How can enabling/disabling data/4G/2G have such an affect on the voice/text signal? I just cant wrap my mind around this

I'm no expert by any means but if I were to take a guess, I would say it may be due to limitations of towers that are closer to you? IE: closer towers provide 2G signal but have not been updated to support 4G? and the towers that support 4G are further from you?
Like I said, I'm no expert, I'm merely taking an educated guess based on what I do know about the technology.

Actually, I dont know either, but that does make sense. If the phone is in 4G mode, then ti will try to connect to a 4G tower, which could be further away. But, there were times I had a great signal with 4G enabled, but it was in H, or H+.... and wouldnt make a call.
Im just happy I found how to get a decent... steady signal. I love the HOX, and I love the CM ROM... but I was ready to pull my hair out with this lol.
Thanks for the input, I may ask someone at the local store next time Im in. There is one kid in there, that is pretty knowledgeable. I think the rest of them know less than I do lol
Well, I spoke too soon. Now I have good reception, but the quality of my connection SUCKS! I have flashed and tried every radio for CM, and while I have a good signal now (around -85/13) my call quality is terrible and are all fuzzy and fade in and out.
I dunno, Im thinking seriously about going back to stock. I love the idea of having control over my own phone, but Im not in this as a hobby. I just want things to work right. Every ROM I have tried has had one issue or another.... wifi connection issues, wifi going to sleep when it shoudlnt, bluetooth connection problems, a dozen apps starting by themselves, radio/reception issues. Its to the point its just not worth it to me. I dont like having to work on anything every day, and if I do, I feel something needs to change in the situation, if that is the case. Dont get me wrong, Im not slamming any developers, or their projects.
When I was younger, I was always the first to get one of the Celeron CPU's and OC the snot out of it. As I got older, I thought... why? Ill just spend and extra $20 and buy the faster CPU so it is more stable, and not have to mess with anything. Thats sort of how I feel now
Just wondering if any one else gets this, sometimes my signal just drops out and I get no service.
Then it comes back it does not happen all the time, I live in a big city Leeds infact so signal is quite strong.
Just wondering if it could be a fault with the phone?
Thanks
I've noticed it happens to me too.

I was wondering if its my device because I live in the city and the signal is excellent around here, my other phone HTC sensation never had this problem. Was concerned it could be software/hardware problem possibly.

It's likely the radio software.

Right I see could this possibly be fixed in next update you think?

It is definitely possible.
I'm on AT&T and have the correct APN settings and have called AT&T with my IMEI. I have significantly worse signal than with my HTC One X. I am not comparing bars to bars, but rather where the signal drops completely. In places where I had low signal but still connected I now have nothing.
Straight talk using at&t Sim and notice radio drops..

T-Mobile on stock ROM i had my first signal drops.
I was fine (or at least never noticed them) from the time i got my phone (day one) without any drops here in orlando.
Drove over to Tampa/Venice Beach area this past weekend and noticed some drops. Had about 6 drops according to my battery stats in 2 days. i had good to excellent coverage the entire time except when it would drop comlpetely (outline of signal bars)
would connect in a couple seconds, but i noticed over night, it would drop for a pretty large amount of time (like 10-15 minutes at a time.)
Mmm defo seems like were all having the same issues, wonder what it could be

I had this issue too, and here's how I fixed it:
By default LTE is enabled, meaning the phone will periodically scan for a LTE network. If you're in a big city, you're likely to find one. Your phone will attempt to connect. However, it fails, meaning it will have to rescan the HSPA bands to connect back. That results in a few seconds of no service. Why can't it connect to LTE? Because by default, the APN is not the LTE APN, for Rogers at least. I'd assume AT&T would be the same. You can test this by dialing *#*#4636#*#*, selecting phone info, and selecting LTE only. You'll see that there is no service. I tested this in an area I knew had great LTE coverage, and that led me to the conclusion that it's LTE causing the signal drops.
So how to fix? Simple, just change your APN to the LTE APN for your carried. To do that go to Settings -> More -> Mobile Networks -> Access Point Names. If you're experiencing this issue on Rogers, change the APN field to ltemobile.apn. If you're on another carrier, you'll have to search for their LTE APN configuration.
After doing this your phone should start connecting to LTE again, and you won't get those annoying signal drops.

A few days ago I let you know that we'd be reaching out on email to some of you for some additional bug report data. I'd like to thank everyone who responded to our email -- the bug data you sent in has been helpful to us in tracking this down.
This is looking like a software issue on our side, and we're investigating a fix.

So yeah the next update will probably fix the issue. It's not so bad in the meantime, Lightflow sill notify you that your nexus has lost signal, and you still get the internet and incoming calls.
We're not alone. Supposedly Google is "aware" of the issue.
i've hcanged my setting from '4g' to '3g' to see if i notice a difference (hopefully will) then when 4g is released or i get a 4g sim, can move it back up
Yes, I'm having issues too. The real problem is the fact that I have a Wilson cell booster in my home (supposed to have up to 5000 square foot range) and my n4 had full bars most everywhere inside. With my n5 It shows 1 to 2 bars if I'm lucky and quite often drops to none! The only way to get full bars Is to stand right under the indoor antenna. Not impressed, and I sure hope this is fixable!

I hate to revive a dead thread, but I was wondering if people were still having problems. Once or twice during the day that I can see I will lose signal for a few seconds only to have it reconnect. Running 4.4.2 so the latest update did nothing to help the problem as far as I can see and I have messed with my APN settings. On AT&T. The Google thread seems to have a lot of different problems on the same thread, and it is a bit unclear if people are still having this problem. This is very annoying for such an otherwise spectacular phone. Thanks and sorry again for reviving the thread... :fingers-crossed:

Actually, there have been several threads on the issues associated with this (emergency calls only, missed calls, no signal,etc.). Ongoing and unresolved for some.

Appreciate the speedy reply. Hope Google gets on this fast. I also have LTE connection issues which has plagued both this and my original device so I am pretty sure its a radio issue. The phone loves to stay on HSPA+ even when there is a decent LTE connection: it's last in the pack to connect to LTE and first to disconnect when compared to others on AT&T.

My N4 with a combo radio sticks to LTE a tad better than my N5 with stock radio. Sadly, morrislee hasn't fiddled and combo'd N5 radios, and I'm not sure they've been tested and sussed out like the N4 radios. Citing the fact some with issues have flashed all the radios so far with minimal success means we wait for Qualcomm, after Google kicks them in the you know where.
