HTC EVO 4G :: Phone Signal - 3G Signal Horrible Same Location
Sep 25, 2010
I can get a few minutes of 4G signal at my home per day, but when it drops out and 3G takes over, the signal will flatline and boot me offline. My 3G speeds are usually around 56-150Kbps or less, and my 4G speeds are around 2.5 Mbps What would cause this ? According to WiMax location sites online, my nearest 4G tower is .52 mile away. I would think that if I actually get 4G signal, then 3G would be constant. Turning off 4G doesn't help either. Is there some setting that I could have turned off that would cause this ? Running stock EVO on 2.2 all the latest updates

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?

i'm beginning to think that in 2.2, if you have a lower signal strength (such as i do in my house), it can't tell your location anymore. in my house, wiht 2.1, it always told me my town. now, with 2.2, it says, fro the most part with a lower signal, "current location." however, when i turn wifi on, it'll tell me my town right away, leading me to believe that since my wifi signal is great in my house, it's giving me the correct location.

My droid x signal pretty much always between -92dBm and -87dBm with 1-3 3g bars. My former droid eris would get -92dBm with 1 bar and also drain incredibly fast.
On the droid x, if I go into google maps, the circle of the cell tower appears and the place I live at is half way within the edge of the circle and the other half is outside of the circle. I always seem to be connected to this tower. Bad luck I guess that I'm on the outskirts of the circle.
Does anyone know how cell towers are distributed? Do they overlap sometimes?
I run pandora with the screen off for a half hour with the screen off and my battery is down to 70%. I have about 15% screen brightness and battery saving mode on.
yesterday, I was on meebo for an hour and 45 minutes and it was down to 60% from a full charge.

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.

Has anyone else noticed having different signal strengths with different Rom's. I have tried using a bunch of different ones and have noticed that the non-sense Rom's tend to have much weaker signal than the sense Rom's. Any ideas as to why that is? I have never had much of signal in my house, but there seem to be a lot of times that I have no signal (when i used to at least have 1 bar stock) depending on the ROM I'm using at the time.

well i rooted my phone with the htc-dev boot unlocker and then used Revolutionary: S-OFF & Recovery Tool 0.4pre4 to s-off my phone, after installing the latest firmware now after booting my phone i cant get a signal and each time i try to register on a network my phone just comes up with an error so i have no signal at all,
iv tryed every single firmware, iv tryed changing my cid to 1111111 then iv moved it back to htc__001 but that doesnt work anymore, iv also tryed a bunch of ruus to bring my phone back to stock but that doesnt work... my phone was factory unlocked so im kinda unsure on what ruu is corrent. my current hboot settings are listed..

I must have the worst luck with phones. My Droid X was working flawlessly since I bought it last week and then suddenly won't get signal! I called VZW and was on the phone with them for over an hour. Tried everything and come to find out, my Droid Eris (previous phone) connects just fine. Some problem came up with the Droid X! Suffice it to say, they are sending a replacement in an week or two and I'm back to the Eris in the mean time. Anyone know how the heck this could've happened? I tried airplane mode on and off, turned the phone off and on, took out the battery while the phone was on, did a full system reset and went through all of the system stuff through VZW.

Had the family over tonight and my brothers phone had four bars... some Samsung unit and my Dad's Motorola Droid had FIVE BARS.... My Incred had ZERO to 1 bar (occasionally)Wassup with that? The battery is definitely an issue already but how about you? How is your signal?

Had my Droid for about 24 hours now and am impressed with the functionality and features, but the lack of phone signal is disappointing so far. I am averaging only about -96 dBm in my home. This is significantly lower than my EVO on Sprint. On the other hand, 3G for data is good - 3-4 bars. What is everyone else averaging for dBM on the phone/voice, is it possible I have a bad unit?

I've been having problems with a Milestone, so i decided to give it away and buy a Desire. Overall, the phone is good. But i'm having a major issue that troubles me: Bought the phone yesterday and immediately updated to Froyo. I'm having problems with the antenna (which i believe is in the lower right corner). By just holding my phone with my hand (not touching the antenna) drops my signal significantly. For HDSPA, it goes down from 3 bars to 0 (but i can make calls) and for GSMA it goes from 4 to 3. As i found out through the menus, the drop for HDSPA is around -10dbm and more. I'd like to ask: is this normal; I know that you shouldn't touch the antenna, but on mine bars goes down all the way just by holding the phone.

So, I'm reading all of this hubby about the iPhone losing signal when you hold it. Mr. Jobs says this is normal for all phones. I disagree. See my video for proof. /so glad I ditched the iPhone and ATT. You Tube - HTC EVO doesn't lose signal strength when you hold it!

has a blackberry and when he connects to my wireless internet at my house he gets better/full service for calling and texting! Now when I connect my new epic to the wireless all that is better is the internet speed.. Is there a way to connect to wireless and get better signal? Does the epic even do this?

My phones signal seems that randomly it has begun to decrease. In my house where i used to get 3-4 bars I'm getting 1-2. I have the moto droid 2.1. All Ive done is add a zagg shield, but i don't think that would be a problem.

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.

Last night my phone decided it wanted to be annoying and started turning itself on and off on its own. This has caused me to lose my network signal.
So far, I have turned the phone off (had it powered down all night while I slept).
Removed the sim card.
Used the recovery options to clear the cache.
Simulated a battery pull.
Thus far, nothing has worked.

i bought a motorola milestone online thinking we werent getting it on canada anymore . which i think is UK version? so i accepted the fact that i had no 3G on it and was aware that the phone frequency and cariier frequency were different. so when i decided to root my phone according to: MILESTONE 2.1 update and root guide - Android @ MoDaCo
i didnt know which SBF file to pick the telus canada one where im from or UK where the build number was the same as mine and where i think my phone was from.. i couldnt unzip the gz file and it kept gicing me errors on the telus canada sbf file so decided on flashing the telus canada one. (and was hoping maybe my 3G would even work. everything ran smoothly and my phone was rooted but now i realize i have no signal on my phone at all. no text or voice calls.. just wifi. i did my research and people suggested that i put APN which i did but that didnt solve the problem also i read that for custom roms theres those 5 files File_Audio , File_Audio2 , File_GSM , File_Seem_Flex_Tables , generic_pds_init that i was suppose to copy and then replace after the root but i was stupid enough not to back up.. so now im stuck and i dont know what to do.. is there an sbf file i can use cant even restore to factory settings because i dont think itll change my firmware..

I only get a phone signal about a third of the times i start the emulator. I've read on these groups that you have to have an internet connection before starting the emulator. Since i'm connected to the internet 24/7 :) this is not the problem I've also read somewhere that you should try do disable all other network connections (which i've done) and the problem persists. I'm using Windows 7 and Android 2.1 + API's emulator. You received this message because you are subscribed to the Google Groups "Android Developers" group.

I want to programmatically measure the phone signal strength in a mobile phone. I don't actually care about the mobile phone or the programming environment: It can be based on android or windows mobile or even J2ME and can be from any manufacturer (please no iPhone). However, it needs to be a real, commercial mobile phone and not a special measurement device. This problem is not as easy as it seems with a first look. I am aware that there already exist a number of methods that claim to return the phone signal strength. Some of these are:
SystemState.PhoneSignalStrength for WM6 RIL_GetCellTowerInfo for WinCe (dwRxLevel member of returned RILCELLTOWERINFO struct) android.telephony.NeighboringCellInfo.getRssi() for android
The problem with the above is that they only return a few (under 10) discrete values, meaning that, for instance, the return values of SystemState.PhoneSignalStrength can only be translated to (for instance) -100 dbm, -90 dbm, -80 dbm, -70 dbm and -60 dbm, something that is not useful for my application, since I'd like to have as much precision as possible. It doesn't matter if there is an undocumented solution that only works on only one phone
