"Time without signal 50%", airplane mode fix, and possible build.prop solution?

[phreak311]

Thank You, and please don't get up on Android phones. Out of all smartphones, iOS, Blackberry, Palm, Symbian etc, I love Android the best. Android may have some small bugs, but you really can't beat it, I mean it's open source...And the features can't be beat...strictly my opinion...

i agree with you completely ^_^

i'm not sure if anyone really knows what's causing this bug... i sure don't. but it seems like with some ROMs, it's there, and some ROMs, it's not. but i had that problem with the stock VM ROM as soon as i got this phone... when you applied the patch, it didn't work? try manually putting it into airplane mode and bringing it back out after 30 seconds? you might very well have a defective phone, or a defective battery... hard to tell.

What's causing the bug? That's easy. The phones are set to CDMA/GSM auto by default when rebooted. The phone doesn't have a GSM antenna, but it "scans" for GSM towers anyway, so it thinks it can't find a signal, because the antenna doesn't even exist.

I don't think that is true. My phone is set to CDMA auto, and it stays the same setting between reboots. I still get the TWS bug without toggling airplane mode.

Yeah, that's true. It's a visual glitch. I've learned this from all over the internet. I posted a solution somewhere in a random thread, but here it is again. *#*#4636#*#* Phone information. change it to CDMA only. Then back to CDMA auto. Exit out of there and use airplane mode like normally. It'll fix the glitch, and have your phone working right until you reboot it.

Edit: And no matter how many times you reboot it, it will always say CDMA auto, but it will really be set to CDMA/GSM.

Interesting, but how do you know it is set to CDMA/GSM? How can I see my phone set to that?

Btw, using launcher pro, you can make a shortcut to the Phone information menu. Add shortcut to Home Screen -> Shortcuts -> Activities -> Settings -> Testing

Oh thanks. I had no idea where to set the shortcuts for Launcher Pro. And that's the thing. After I first got my phone, and wondered why the battery drained quickly, I noticed the glitch. I was like.."50%? That can't be possible." I typed it into google and it's not just a bug with our phones, it's a bug with all CDMA android phones. I've done lots of research on it, and attempted at fixing it myself. It's just a visual glitch though. How will you know? Well, just keep using your phone and Time Without a Signal will increase until it hits 50%. You'll never be able to see it set to that upon reboot, but it always is. The current Aospmod ROM fixes that issue completely. I'd love to know how he did it.

There's an app in the market that I believe does the same thing. But I have an update on my girlfriend's optimus V. I flashed back to AOSP CM7, and flashed the newest update. Then applied the TWS .apk. I then switched her radio back and forth between GSM and CDMA auto. Put it back into airplane mode, and now her TWS is 3% and the battery is lasting longer. But for some reason, I can't get this to work on a 2.2 ROM at all. Oh well, Gingerbread is much better. I hope it continues to see better battery life because of this, because I already ordered a replacement today :/

You need to change ro.telephony.default_network to 5. Then on boot it will be CDMA only.

do you know the other codes for this setting? is there a listing somewhere of what each number means? i'd like to find the one for cdma auto, so i could set it to what it should be. where did you come across this information?? thanks!!

 

[cpshelley2]

also, i've checked the build.prop from aosp and his default_network is 4, yet the problem seems to have been eliminated in his rom... just curious as to how this one setting could fix the problem...

Never heard of this before, but I'll give it a test here in a bit.

And yes AOSP is also 4, but it may have the menu corrected.

that'd be amazing, Leslie!! i would test it myself but i'm expecting an important phone call and can't afford to be messing around with radio settings right now :-\

4 is cdma auto (or it is supposed to be). Maybe a small script can be used to fix this.

setprop ro.telephony.default_network 5
setprop ro.telephony.default_network 4

Maybe with a pause in between. I'm going to try this and I'll report back.

 

[obijohn]

The numbers are:

0=WCDMA preferred
1=GSM only
2=WCDMA only
3=GSM auto
4=CDMA auto
5=CDMA only
6=EVDO only
7=GSM/CDMA auto

 

[cpshelley2]

0=WCDMA preferred
1=GSM only
2=WCDMA only
3=GSM auto
4=CDMA auto
5=CDMA only
6=EVDO only
7=GSM/CDMA auto

where were you able to find this information? aside from this setting, i've been searching for a listing of build.prop settings and values.

 

[cpshelley2]

also, what is the difference between CDMA only and CDMA auto?

 

[mmarz]

4 is cdma auto (or it is supposed to be). Maybe a small script can be used to fix this.

setprop ro.telephony.default_network 5
setprop ro.telephony.default_network 4

Does not fix TWS

Does not fix TWS

mmarz, how did you test this? did you use setprop or edit your build.prop and reboot? just curious, as i was going to try the latter...
