Is there any downside to leaving both wifi and 3g off at the same time when not going to be using the phone for a length of time? I tested this, and even with both off, I still received incoming text/phone call. I guess the 3g connection automatically comes on when needed? keeping 3g off obviously causes the time without a signal % to skyrocket but thats normal since its set to off. If 3g is set to off and only turns on when needed, then wont leaving both wifi and 3g off extend the battery even more than just leaving one or the other always on? (assuming you arent going to be needing to use the phone or needing to have background data enabled to update email or whatever).... I guess I always thought that one or other had to be on in order to receive messages/calls.
+1. I like Ubuntu. I actually installed Ubuntu on my wife's old laptop when Windows kept needing more and more resources. It worked great for a while until the laptop died of old age. If my computer illiterate wife can easily use it anyone can. I'd use it on my PC if I didn't need Windows for an SQL server and my inventory management system. I even tried running it inside a VM, but it didn't work. I'm still bummed.
This actually isn't true (and maybe another clue?). I occasionally have the TWS bug crop back up without a reboot. However this only started happening after installing this:
http://forum.androidcentral.com/opt...on-connection-checker-app-fix-3g-problem.html
Hmmm, interesting. That app, from what I remember, restarts just your 3G if it can't ping google. I wonder how that plays into all of this.
I beleive it does the following (based on the logs):
- Turns Wifi off if can't ping. Turns it back on after a wait time you can specify.
- Turns on Airplane mode if can't ping via mobile.
I'm not sure that second option is totally accurate because I've noticed that when it turns airplane mode back off it fails to restart wifi. So it may be toggling the individual connections?
Unfortunately I haven't paid attention to see which scenario corresponds to seeing the TWS issue again.

It all goes back to the *#*#4636#*#* menu/radio setting. The Network app, the XDA app, all use that menu/setting to reset things. That menu/radio setting is what ro.telephony.default_network 4 is adjusting. The XDA app is not actually using airplane mode, it uses that menu system or radio setting to turn it off and on. I will bet this app is using that menu/setting as well.
Airplane mode is not using that and that is why it isn't effected.
Airplane mode does not change any settings, it simply turns them off and on. Retaining what setting it had before.
Every time I use(d) any app that touched that setting to reset things, I ended up with radio problems (it would not reconnect after a signal loss). Months ago I documented this on two separate forums and both times I was told I was an idiot, despite being able to repeatedly replicate the results. A few were able to replicate it as well, but because I didn't have a source for the theory (about the menu having an issue) and it didn't work for everyone, everyone dismissed it.
Sorry for the edits, trying to make it easier to understand.

It's ok. You are in a safe environment and are among friends. Now, show us on the diagram where you touched him:
But seriously, can you go into depth about how to replicate the issue?

Install a fresh rom, with no radio tweaks.
Put on streaming radio, drive into a 3g dead zone, drive out of the dead zone and watch your signal return and music resume. Normal. of course.
Now trigger a radio change, either manually or automatic, with an app or without and repeat the above. What happens is when you entered the dead zone, and came out, the phone would stick and not reconnect. Instead of dropping to 1x or trying to reconnect, it simply got stuck, probably trying to trigger GSM. When sitting on my nightstand, my phone loses 3G a few times a night, so it was easy to test this, it just took me overnight to do so. I spent a week back and forth replicating the results over and over, with various roms and apps.
Keep in mind, Virgin has supposedly done some work on this (remember that big outtage for system maintenance?) so it may not have an effect anymore. I haven't checked, I simply avoid those apps, but it showed me there was something to that menu.
More:
According to Linx2cross, Froyo does not allow apps to turn on and off the radio completely directly. I'm not sure how true this is, but if true, that would explain why they all use that menu. He too was having the same issues and found it was the apps causing the problems.
TVCSS also came to the same conclusion about that menu being an issue.

You forgot that the phone also has standard 1x CDMA!
You are fine using 1x CDMA for calls and texts (and data, if you don't mind the slow).
I don't know how you have set 3g to off, but it is quite likely that it is doing what it says and staying off the whole time, and you're just on 1x. Voice and texts never use EVDO, which is data link only.
I can imagine a hypothetical scenario (you live someplace where you have nearby 1x tower but only intermittent connection to a distant 3g tower) where turning 3g off would save battery because the phone's radio wouldn't be intermittently registering with the 3g tower all the time.
I would guess that under normal conditions, turning 3g off would have no effect on power usage, because both 1x and EVDO are part of CDMA2000 and use the same spectrum. The physical layer (radio link) is the same. CDMA allows for actual power usage to be dynamic, based on how much power is actually needed (i.e. how far you are from the tower) -- this allows more devices to share the same spectrum (less interference) and minimizes power use. So, actual power requirements are going to be variable over time and distance. If something works for you, then that's great.
FWIW, I don't think Connection Checker is doing this...if you read the post from the author it says:
"If it detects that your Wifi connection isn't working, it'll turn off Wifi and fall back to mobile connectivity (Wifi is re-enabled after some time). If your mobile connection can't pass data, you get a notification and airplane mode is toggled."
(and either way I have had ZERO connectivity problems since using it, and better battery life)
No the time without signal fix is NOT cosmetic at all. My TWS is 0% on my Optimus S and I get at least 14-18 hours a day with my phone. My girlfriend has the Optimus V and her TWS is at least 50% and she can't make it 6 hours at work without her phone dying. So I assure you, this is not cosmetic.
Unless her TWS is stuck at 50% exactly and does not change, she is not suffering from the same bug. She could just have bad reception. Try doing the PRL update on her phone.
If it is stuck at 50% exactly, the airplane toggle should fix it. This won't lower the TWS value, but it'll stop it from being stuck at 50% for no reason.
