Motorola Droid :: Cell Signal Strength Meter App
May 4, 2010
anyone seen an app that simply reports yours signal strength? the built in one (settings > about phone > status) seems to report, but in a way that makes some sense. for example, anyone know what -90 dBm 0 asu really means?
I have a cool app called GPS test that shows the GPS strength - bar chart and number and color - of GPS signals.
I have another app called No Signal Alert that tells you when you have lost your signal. I emailed them to incorporate a signal strength meter, as it seems a logical app to have it.

I'm writing an android application that collects cell signal strengths. I am having trouble getting the "current" cell signal strength, but I don't have any problem getting the "neighboring" cell signal strengths. To get the current cell signal strength, I created a PhoneStateListener and implemented the onSignalStrengthChanged callback. It works, but not very well. It seems like the signal strength hardly ever changes, and resolution jumps to only a few numbers. I would accept the answer that the resolution of the signal strength hardware is coarse, but when I use the TelephonyManager's getNeighboringCellInfo() method, it works much better. The signal strength readings from neighboring cells change frequently, and they have much better resolution.So, how can I get the current cell signal strength in the same way that I am getting the neighboring cell strengths? It seems odd to me that the functionality of the neighboring cells is better than the current cell. Am I missing something here?I would also like to directly call a method from the telephony manager to get current cell strength, as opposed to a listener, if possible. If anyone knows how, please let me know.

Is there any way to retrieve the current cellular Signal Strength (RSSI) on Android 1.5?
I know there's a way to listen for signal strength updates through the TelephonyManager, but this seems to only give a "state," not a numeric value.
Is using the RSSI field on a neighboring cell fairly accurate? I'm guessing not, but I'm running out of ideas.

There is a site Cellreception.com that tries to aggregate cell phone reception from users who bother to leave reviews. But data collection can be made much more easier, even passive:
Make an app that sends the phone's GPS location and the 2G/3G signal strength of the current provider in that location, to a centralized database, aggregate the results, and make them public online.
Nth Signal seems to be an app like that, but I can't find it on the market, and the reviews on Androlib are not good.

What more can be said The Incredible meter is totally defective. This is what I got today. Also by popular demand direct Db readouts on both phones. Here is the proof the HTC battery bar meter is 110% DEFECTIVE!

I use the GPS functions and My Tracks quite frequently on my DX. I was wondering if there was a way to check to see which satellites the DX locks on to and their strength - much like a GPS unit (Garmin, etc)?
I would like to use this information to check some settings while on trails as well as getting the Lat/Long of my position.
If I have to use an APP to do this can you recommend a good one?

The tricorder app is supposed to be able to but it doesn't show it on my droid. Same thing goes for the "Antennas" app.
Anyone have any suggestions?

I am trying to write a very simple Android application that checks the signal strength of the current cell. So far, I have only found something called getNeighboringCellInfo(), but I'm not really sure if that includes the current cell.How do I get the CURRENT cell signal strength in Android?Does getNeighborCellInfo() get the current cell? It doesn't seem like it based on the results that I have been able to get with it.

Just wondering if I'm setting myself up for excessive battery drain on a DROID given my signal at the house. I'm testing this by looking at the status screen of my VZW blackberry My neighbor next door has a 3g ATT blackberry - he's getting -70 (solid) in my home.

Is it built into the OS or do I need to download an app from the market?

So far this thing is blowing my dinc out of the water in the signal strength department. I live where I basically have no service (rarely below -100 db) and I am doing side by side comparisons and it isn't even close. The dx is loading pages snappy when my dinc isn't even getting 3g.

Some professional reviews (engadget and phonescoop) have noted signal strength issues with the Droid 2. For example, see:
Review: Motorola Droid 2 : The Three S's (Phone Scoop)
Particularly for those who have/had other Verizon phones, have you noticed any signal strength problems, trouble with calls, or slow data?

I want to reach out to others here before I take my Moment back to Best Buy to exchange it for another Moment.
My signal strength fluctuates wildly just sitting in the same spot. With the Hero I got a constant 5 of 6 bars, but the Moment will vary between 0 and 5 of 6 bars. But it's more complicated than that.
It seems that whenever the EVDO data kicks in, it causes the signal strength to drop to 0 or 1 bar. Once the data is idle, the EVDO indicator turns grey and then changes from EV(^v) to EV(D). At that point the single strength will return to 3 or 4 bars.
At times, though not as consistently or often, the EVDO connection will fall back to 1xRTT and will switch between them every few minutes. This will occur even when the signal strength bars are in the 3 to 4 range.
So, the my questions are...
Does the signal strength apply to the data signal or just the voice signal?
Is there any legitimate reason for the signal strength to vary wildly like I've described, even when sitting in the same recliner where the Hero had a constant 5 bar connection and data service that never wavered?
Is anyone else having signal strength and/or data service issues?
Should I exchange the Moment for another Moment or will I likely experience the same issue?

Is anyone else seeing this behavior?right before I make a voice call the droid will show 4 bars, when I place a voice call it will drop to 0 bars and the voice quality is pretty bad.In the phone settings you can see the DBm signal strengh and before I make a call it will show -96 and when I make a call it will go to -104.I have noticed this even when right on top of a cell tower.You actually don't notice it when the signal is very strong, but on my droid it does appear that the signal degraded significantly when doing a voice call.It also does the same thing when the Wifi is turned on, it's almost like it's switching to another antenna for the voice when wifi is on or you make a call.So far I have not been impressed with the phones voice quaility at all.

I think I figured out why sometimes my Droid stays on for 1.5 days and sometimes after 6 hour of just being idle the battery is drained.
When wifi is turned on an connected to a network, the cellular signal is way low and it just drains the battery.

I upgraded to the second 2.1 leak for the eris and my usually always shows that I have one or two bars of signal strength but when I go to about phone it shows that i have -89db signal strength, is that good and is there just something wong with the bar signal indicator or is that a bad signal and if so how can I increase my signal? I already tried using the *228 number thing to update my prl but that didn't help. Before the leak i would have three or for bars

I have had my Eris for a week or so and am getting concerned about it's reception. I am noticing the bars will fluctuate wildly while sitting at my desk in an area that has great Verizon coverage! I am looking at my Signal Strength and it is flipping from 89 dBm 12 asu to 0 dBm 0 asu without even moving the phone! What is going on?? Do I have a bad device, or is this normal? Thanks for any info.

Couldnt find my answer on the previous topics. But my phone on verizon hardly has full signal. Im running 2.1 on a brand new phone that i bought off a guy from craigslist. It seems my signal is only 1 to 2 bars most of the time, giving me around -86dbm. Sometimes it will be 3 bars, then it drops to one or none. Wondering if this is killing my battery too. Is there some update that fixes this? Or some test to perform if whats happeneing is normal or what?

I have seen it in a few ROM's with EVO Framework, namely Adrynalyne's Frankenrom_B6. The EVO has 6 bars in the signal meter and the Dinc has 4. If I am using a ROM that has the EVO Framework, Virtuous 2.2, can I MOD my Signal Meter to be this one? If so, where can I find this?

I have noticed that my wifi signal strength is crap. I can be in the same room about 4 ft away from my router and my signal strength is 2 bars on my wifi. Also on my 3g coverage I am at 1-2 bars max. When I 1st got my phone never had this problem. Any ideas?

I would like to know. Not even rooting helped the difference in signal from 1.5 to 2.1 (nonroot or root versions)
One theory is that the 2.1 signal values are different and thus report a difference in signal in the bars and in settings.

I just came from a Verizon Corp. store and low and behold there is tech guy from HTC there showing the employees the ins and outs of the Inc. So we got into a discussion about the signal strength meter here is HTCs explanation on why it seems to be wrong. He claims as part of the power management system the phone when not in use meaning not making a call or connected goes into a minimum power mode that also effects the signal meter. He made a call on my phone to how how it works. Once the phone call is placed you immediately see the bars raise and the 3G come on after disconnecting the bars fall again once in the power saving stand by mode. So I guess its not defective after all just very smart.

I am virtually unable to get a wifi signal in my house on my droid x unless I am a few feet away from my router. None of my other wifi devices in my house are having this issue. When I check my wireless settings on my dx it says the signal strength is poor. I'm running rooted GB 4.5.602. Does the baseband have to do anything with this (BP_C_01.09.13P)?

The typical method to obtain signal strength has been to extend the PhoneStateListener class and override the onSignalStrengthsChanged method. Anytime the signal strength changes the system will call this method passing in the new ASU.
Since this method is now deprecated as of Android 2.0, how are we suppose to go about obtaining the signal strength? I tried using the method above on Droid (CDMA) and the ASU passed in is always -1.
There are also no details in the SDK as to why this was removed or what we are supposed to do now. http://developer.android.com/reference/android/telephony/PhoneStateLi...

I am having horrible signal problems. My old phone the ENV2 in the same exact seat I am in right now I had full signal strength. The Eris on the other hand, I have none, it flips from no bars to X all day long. I can not receive calls nor can I make a call. Has anyone had problems with theirs? Or what might I be able to do ?

I just did a little test and sat them side by side. the moto showed -83 and the inc showed -79. both fluctuated but the inc was consistently 2-4 lower than the droid. if you still have your moto,give it a try...
