So in my house I have terrible 4g service. I have a 3g extender and for my old iphone it made life great. So i found an app called phone info thanks to something i was reading on XDA, it allows me to switch to 3g from 4 g, and the reception in my house is awesome now. what i am wondering is if there is any way for me to have the phone automatically switch to 4g when i leave my house? will tasker or llama do that for me? or is there a setting in phone info i am not aware of?
If you go into settings>network, there should be a setting to switch between CDMA and CDMA/LTE. I'm pretty sure you can set an NFC tag/sticker (e.g. TecTiles) to do that, which wouldn't be automatic, but simple as swiping your phone over the sticker.
I'd imagine Tasker would have some option for this, too, tagged to location. I don't personally use Tasker, so I can't test it for you.

Hey guys,
As the radio stack is the second cause of battery draining after the display, I was thinking about a way to save battery life by reducing the impact of the 3G connection. Most of the energy saving apps on the market are only disconnecting the phone from the APN, but this isn't a great solution as each app could be set to update at different times and thus being unable to download data even if the user sets some exceptions. So I thought that an application which operates in the following way could be great to save power:
- The phone uses the 3G network while the screen is on;
- It switches to 2G when phone is in standby mode;
- It disconnects the APN data connection while the phone is using a WiFi Network;
Obviously to avoid possible issues during the switch between 2G and 3G the following rules are applied:
- If there's an incoming call or a phone call is being performed, there won't be any radio switch until the phone call is ended;
- If there's an incoming SMS/MMS, there won't be any radio switch until the text message is fully received.
Unfortunately as I'm not a Java developer I can't code anything like this. But let me know what you guys think about my idea and if it's technically feasible... Maybe some developer could be interested into further exploring my thoughts and will try to create such an app
Cheers
I'm not a developer but I think it sounds like a great idea. I go into settings and switch it to 2g when I'm in spotty areas outside of town. I have to work a bit to keep my N1 battery alive all day...
Hello I'm new here.
I don't know if your suggested profiles are the best case scenarios. You would need to calculate your data throughput, not just the radio power.
If you need to send 100 packets, your radio would be on the longest for edge > 3g > wifi. So, even though wifi uses the most power, it would be for a much shorter duration.
A profile for "place calls only" would work somewhat like airplane mode, but still keep track of towers. Your phone just wouldn't register on the network unless you wanted to place a call. You would miss your incoming calls, have no data connection, or sms. But, you could have it check at an interval for voicemail or sms. This would be most useful for "ringer off" situations like class or meeting.
Afaik Android is always connected to the APN even if the phone is not downloading anything, consuming a lot of battery power. On other platforms, i.e. Windows Mobile, the connection can be terminated by user and re-established when an app needs that.
The amount of data downloaded by widgets, Google mobile applications or apps which operates in background like eBuddy or Facebook should be quite low, so downloading the required data by using GSM or WCDMA while the phone is in standby would be pretty much the same. The only difference is that downloading stuff using GSM/EDGE should take much less energy power.
So that's why I thought about the app I described before: the phone can save a lot of energy power while in standby and be back to its full horsepower when there is any kind of user intervention. Pretty much the same thing that the system already does for CPU usage. It scales to the less consuming protocol (or, in the case of CPU, frequency and voltage) to save power
I know on the google api it isn't possible to do this, but I don't think that isn't the problem.
At the moment you have 3 options. GSM only, WCDMA only and GSM/WCDMA. Whenever you switch between the 3 of them, the phone will lose signal for 10 seconds before it can find the best network. So the switcher here is not the best as you will lose connection, and what if you are downloading something at the same time...
What you need is when the phone is on GSM/WCDMA that it knows the best network to pick from depending on the phones lifecycle. GSM/WCDMA loses battery power because it always tries to find the best network to connect to, so for example if you are on GSM it will constantly try to find a 3G network etc (as far as I understand it).
What we need is the ability for the phone to stay on GSM when the phone is idle and then when the phone is woken up to automatically start to search for a WCDMA network and then gracefully switch over like it does now. For this I have no idea if it is possible as I don't know how the scanning of the network works. If it is possible then that would be wicked. But this is what we need.
my preference would be if the phone would stay on 3g as long as any possible even if there would be a more reliable 2g connection and only switch to 2g if there really is no way to connect to 3g. turn of apn if the screen us turned of for longer then 1 or 2 minutes and only check every 15 minutes or so.
most of the time I'm on 3g only mode . since I live in a city I got good coverage almost all over the city. only problem is that when there is no 3g available also my phone is unreachable. I don't really miss data connectivity when there is no 3g since 2g is so slow that I rather have no internet at all but not being sale to be called or texted is a major disadvantage...

Generally my sensation has a decent reception. Most of the times i`m able to get a decent 3G/HSDPA signal without any problems.
The problem is, that I live outside the city and at home my (3G) reception sucks. My Sensation seems to suffer from this poor reception a lot more then my previous Desire-Z.
The 2G connection is fine. When the phone switches to 3G however, I only get one bar and the connection frequently drops so that I have no service at all. When i set the phone to only use 2G, the connection stays stable and since I have wifi, having only GPRS at home is no problem.
I don`t want to leave my phone on 2G only because when i`m not home, the 3G connection is usually fine. I was wondering if there is a way to manually change the 2g/3g switching treshold so the phone will only switch when it has a decent 3G signal. I tried to set GSM Auto (PRL) at the #*#4636#*#* menu, but this doesn`t do the trick.
Thanks
You might have already found an answer to your question, but in case you haven't, you might wanna check out WMLongLife.
It has the ability to automatically disable 3G when you have access to a WiFi network.
Hope this helps
I would be quite interested to see the trick how you are running such a deep system tweak application from Windows Mobile on a Android phone ...
Best regards,
dingolino
But there is a possibility with Tasker

I used tasker to achieve this, when it notices my wifi ssid, it switches off 3g. The down side is that wifi needs to be on ask the time. You could also use "show and switch 2g/3g" from the market, with this APp you can switch with one button or use a schedule.
Guy from reply #2, this is an Android forum not winmo. Winmo it's dead.
I know for some the title is a little contradicting, but here is what I am looking for:
I would like to turn off calls and sms, and enable only mobile data (3g). Airplane mode is not good for this as it turns off mobile data. I have done this on an old windows mobile phone I used to have (motorola q) but I haven't found much info on android for this. I know some people have also asked the same question but no answer (forums.androidcentral.com/htc-evo-4g/61387-how-turn-off-cell-phone-radio.html).
I have an Samsung exhibit 2, it's on gingerbread.
I am wondering if it isn't as simple as to replace the normal phone apks with the ones from a tablet (since tablets cannot make voice calls or sms) was anyone tried this? Maybe can point me to a place to try? I think the apks to replace would be the 2 being discussed here:
android.stackexchange.com/questions/7133/how-do-i-turn-off-the-cellular-radio-without-disabling-bluetooth
Thank you.
Tablets can make voice calls AFAIK. Although one looks very stupid holding a large pad onto the ear. Normally, it goes to Loudspeaker by default.
Anyways, what you are looking for might not be in Android. From the look of it, this is a driver feature. So if the drivers of the phone's radio does not support this feature it might not be possible.
Anyways, is it possible to do this in real GSM radios? Isn't GPRS in the same band as in Voice calls? I'm not sure about HSPA.
Why would you want to do that?
Do you just want to disable texting and calls? (You could just ignore them?), or you could just use Wifi.
In older phones (like 2g and basic cell phones), they did not have mobile data, so all they had was the cellular radio. In newer phones though, the cellular radio and 3g/4g is the same piece of hardware, so it is not possible, as far as I am aware, to disable one or the other selectively. Sorry
If you're own a sprint phone and try to download a phone call can break the connection. I am also looking for a way to temp disable the cell radio while downloading.
"Juice" might do it. I know some of the battery saver apps will allow this customization where you can have data only, radio off, radio on data off...etc
I currently have a Nexus 5 and I love the phone so far. The only issue I have right now is has to do with my Airave 2.5. Long story short my phone recognizes the LTE tower close by and when a call comes in it automatically switches from LTE to 3G. (Totally normally and no issues there), but it doesn't first look for my Airave (Which it needs too service is very hit and miss at my location voice wise). Either way it doesn't really matter since I use WiFI while at home for data. The work around is to go into Settings--> Wireless & Networks - More.. --> Mobile Networks --> Preferred network type. Change from LTE/ Global to 3G. Once I do this my phone picks up the Airave perfectly while I'm at home and my calls don't cut out all the time. But when I leave the house I want to turn back on LTE.
My question is this... Is there a way to program an NFC tag to toggle those options. For example one tag in my car I hit and it flips it to LTE and another tag at my home flips it to 3G??? I've tired a few different applications with little success since that type of setting normally require root but not on the Nexus 5. Any recommendations or things I could try?
I'm trying to understand and refine how my watch works with Digits. Things like how to save battery. What connects when? Do I "need" a data? Anyone wanna talk?
So nobody out there who knows Digits? Well alright then!
I believe the Digits in T-Mobile works similar to my carrier in Brazil.
Actually the 4G of watch only work when your phone has disconnected and you do not have connection with Wi-Fi network.
In Settings have a option for turn on the cellular network in always time, but the own watch warns that consumes more battery and you do not have necessity 'cause when connected in Bluetooth your calls going to clock too.
Therefore your Watch going work this way: Bluetooth first, after Wi-Fi and lastly (you can disable permanet the Wi-Fi) the network cellular.
Sorry, I don't speak English good.
