Better 3g signal (for me at least) - Verizon Motorola Droid Turbo General

I just flashed the radio image from 21.12 firmware with RSDLite and saw an amazing increase in 1x signal! from about -120 dBm to about -95 dBm! ... thought I would share this info BUT I AM NOT SURE IF THIS HAS A NEGATIVE CONSEQUENCES ... AFAIK, worst comes to worse, you can just reflash the updated baseband
EDIT: okay so dont do this... it disables the ability to turn on wifi, dont know why
EDIT: logs tell me wifistatemachine: failed to load wifi driver... maybe if there was a way to implement the new wifi drivers into the old cell radio image or vise versa. Also, thread post should say 1x not 3g

Why are you worried about 3G signal?

Because a signal change from 120 to 95 could add hours of battery life if you are getting a bad signal in your house... cell standby is sucking up about as much power as my screen

Do you not have LTE in your house?

I do, but what would that help? I would still get power drain from 3g scanning unless i disabled it... and phone calls dont run over LTE so that would not be a fix. I would love if someone had a solution for me, but am I wrong about any of this?

can someone check 3g and LTE signal strength before and after toggling advanced HD calling? I got the same -120 to -95 increase in signal and I think that is essentially what I was doing by downgrading the radio image to pre-VoLTE

Because 3G isn't active when LTE is.
Phone calls also don't run over 3G, they run over LTE, or 1x.

I was under the impression that 1x was 3g? And i just tried to make a phone call on LTE only and it doesnt work, so I am sort of confused now
Edit: I guess i shouldve thought about what VoLTE meant, and how i had it toggled off.

1x is voice only, 3G is data only.
Generally speaking (sans dual radio devices), one cannot run at the same time as another which is why Verizon never had voice and data at the same time before LTE.
I've found much better battery life with VoLTE on, if the LTE signal is strong.

Thank you! I've had it off for so long because I didnt care about the voice/data feature but now Ill have to try it out since I understand how it operates. I have a stronger LTE signal than I do 1x signal so im hoping it will help. I also toggled mobile network mode to LTE/GSM because it now only scans for LTE as far as i could tell so it may save some battery by not worrying about the 1x signal... just speculation

If you are really brave, set your radio to LTE/GSM/UMTS and try that out.
I *believe* that should work only on VoLTE, and would turn off 1x.
I believe you can set LTE only with a google play app too.

Yes that is what I meant when i said LTE/GSM... I dont see why it wouldnt work. Advnaced signal status app is only registering LTE so i guess thats a good sign

3G drops to GSM when receiving calls and during calls

I searched all the threads and found nothing on this as far as I can see. I have been having this since day one with my G1. Every time I receive a call on my G1 or during the call it drops from 3G to GSM. I had stock T-Mo roms on my G1 (Pre/Post Cupcake) then JF 1.51 and now cyanogen 4.0.2 and this problem persists. I called T-Mo a few times on this and they exchanged my G1 3 times and gave me a new battery and charger free of charge. Does anyone else have this issue or know of a work around? This happens when I am at home and work. I travel for work to different locations and it still happens. When my phone rings it automatically drops 3G and goes to GSM (no icon next to the radio icon in the status bar). While making calls it stays on 3G for about a few seconds before it craps out and drops to GSM. It totally skips EDGE and GPRS. T-Mo said they sent out radio antenna tech's to the antennas near my home and they said all is fine and dandy. I live In Queens NY and work in the Bronx. When I travel to Brooklyn its the same as well as driving though Manhattan. I hope someone can help me with this.

ive always had this as well .. just never considered it a bug lol ... but i could see why someone would wanna keep their 3g while on a call .. reminds me of how sidekicks would lose data connectivity due to a call

Could you elaborate?
If you've had 3 G1's and a tech says there's nothing wrong with the network then it's clearly an issues with cupcake, be it a feature or a bug...
I don't really see why you would want to keep data conectivity while in a call, (unless you're downloading something in the background..?) so it sounds like a way to save battery..

Here's a perfect example where 3G would rule when working properly.
I'm talking to my wife on my BT headset while driving home from work. I have my G1 on my dash with google maps running with traffic patterns showing. While talking I am able to talk clearly on 3G and still see where traffic is building so I can avoid it. Being stuck in rush hour in NYC sux homeless man [email protected] Whenever I do this and my 3G connection drops my call quality drops and we both hear it while we're talking and then it cuts in and out and the call drops then I dont get updates. It's a feature I would really like to have. Even when Im working and talking and downloading a new update of an app. This happens when I am at a static location as well. I know driving from cell tower to cell tower can have bad effects but it does the same when I'm just at home or any of my work locations. When 3G works properly which is rare its amazing. Its helped me get un lost and find my way many of times.
Point being when T-Mo released the 3G statement they said all users with 3G phones will expierence higher call quality from the extra bandwidth. Why would they cap or or disable it when they are promoting it? I see the the point of saving battery life but it still shouldnt be happening. 3G is made for that feature to work voice + data being accessed together.
It might just be there 3g network, imo tmobile reception is horrible. Like at my house it is so f'ed up, I can sit in my chair and have 3 bars then walk 2 feet and lose service. It does this all through my house and at my work. They said it must be something in the buildings I am in, bull**** I say because ATT never does that nor did vzw when I used them.
same thing happens with me and 3g and calls..also about the house thing, hows this one for u ill be sitting in the same spot and have good 3g reception and all of a sudden it drops to edge. I know a way around this is to set phone to 3G only but then in areas where theres non im screwed
I don't get it. My wife who had the original iPhone and then 3g and now 3gs never had this issue. She would stay on Edge and 3g depending if she waned to save batery life. My old BB 8700g would always stay on Edge never drop to GSM in my apartment. My 3G doesnt even fall to Edge it goes right to GSM. This is really annoying.
every t-mobile phone I have does this
I'm pretty sure its normal
No one knows if this is a hardware, software, or network problem. Except maybe HTC/T-Mobile/Google.
If your phone stays connected to 3G, it's all good. If it drops down to EDGE, even if for half a second, it will NOT reconnect to 3G until you hang up.

If any of those 3 know they should fix it or at the very least advertise that the calls you make are dropped to the lower bandwidth of the GSM network.
T-Mo finally got 3G for the last year don't dumb it down guys. Fix this.
Yes it is true once your phone drops beneath 3G it will not go to 3G until you hang up the call.
try running 3g only or wdma only by creating phone info shortcut on anycut .. im going to try that out and see if it ever drops .. should be a temporary fix for you atleast with the whole maps thing and such but if you ever in an edge only are your screwed

I changed it to wcdma only in phone info. Hopefully this works. Everywhere I travel to throughout NYC has 3G. Hopefully this works. Also I have noticed that when downloading anything from 3G be it the market or browser it would drop from 3G to Edge as well.

While at home downloading apps from Android Market on 3G with wcdma only selected the radio dropped with no netowkr connection. Bust.

Did she use att or tmobile with the iphone? Because att has a much stronger 3g network then tmobile which could be why. I am pretty sure it is something to do with tmobiles network and not your phone, perhaps your area has to many users for it to stay on 3G. I have read about how the cell towers work and they have only so many bands for each user to access at any given time so if tmobile doesn't have enough towers or those things mounted on the towers it may be set up so you only get 3G for data usage and not calls since they don't technically require it to work.

My wife is on ATT. Isn't lower frequency better at penetrating through walls and such? (T-Mo 1700 MHz and 2100 MHz compared to ATT 1800 MHz) They haven't booted their 850 MHz antennas yet so I hear.
If that is true then why not boot me down to Edge or gprs why all the way down to gsm? I been living in the same area for 26 years. I have been with T-Mo before they even had antennas in my area and walking outside was the only way to get a signal with my phone. Now I get full reception in and out of my apartment and 3G connectivity in my apartment with a signal strength of -93dBm through out my apartment on 3G and -79 dBm on Edge.
T-Mo stated that this should not be happening. Hence the 3 phones new battery and charger and techs to the antennas. I'm starting to think its a HTC Android problem and not a T-Mo problem. Hopefully a new radio update can fix it.
I didn't even know GSM was still used in that way, I thought GPRS would be the bare minimum. How can you tell the difference? I use to only get a G icon and I looked it up and for the g1 it said that meant GPRS, what does it show for GSM? Not like any of this matters though.
I really have no idea why all this is happening to your G1 but I hope it gets resolved, good luck.
edit: on the tmobile coverage map it says edge/gprs and 3g, no gsm. does that make any difference? I checked for NYC overall not any specific boroughs.

GSM is what Edge Gprs and 3G run off of. Think of it as a progression. GSM>GPRS>EDGE>3G.
The way I know it is on GSM is to the left of the Radio icon on the home screen there is another icon that shows the network your on. 3G=3G E=EDGE G=GPRS and no icon means GSM. GSM is still being used. Most SMS and MMS messages get sent to your from through GSM while you are on a call.

Hero, have to choose: Data/3G or voice calls, HTC reinvet the 90's!

Hi,
after having several missed calls going straight to my answering machine on my new HTC Hero. I was getting a bit paranoiac, so I've decided to test in/out calls.
Basically, 90 of my incoming calls were going straight to my answering machine. Out-call were about 30% KO
After several tests, to make sure there was a problem, I've decided to request for support from HTC.
Support told me that I should shut the 3g connection every time I would want to receive a call .
So I tried and Bingo, if 3G is activated, I get 10% of the calls, if I deactivate it 90% success.
So you'll say, I should be happy? Right? Wrong!
The main use of that kind of phone is to have a data integration, otherwise I would have kept my old nokia from 10 years ago..
Here basically, if I follow HTC idea, I should keep the 3g closed, sometime, I should switch it on to get my mails, thanks to the non true push capacities (ok this one is not htc) then wait for the sync, maybe force it , get my mails, and then, shut 3g back and pray that no Über important call would have been done.
Well that plain sucks!
Never had such a thing on my previous Data friendly mobiles, why should I accept it on the Hero?
If someone have come across this bug, cause it is a bug, how did he/she managed to fix it?
Thanks
works fine on mine....i suggest you are on a ****e network, or on only 2G where you are. that's what usually causes this.
I guess they suggested this because it sounds like your network hasn't figured out how to route calls properly on their network when data is active, and they dump it straight to voicemail when there is a data connection active.
not the phone's fault, the phone won't even know that the call has been missed, the network simply does not route the call through and sends it to voicemail instead.
i had this on O2 a while ago. went to t-mobile (who knew how to set up their network properly for data) and never had this issue since when i am on 3G coverage. if i'm on 2G signal and have active data then yes, i miss calls. but that's how 2G networks operate.
it's truly shocking how many networks out there have absolutely no idea how to set up their networks properly for data!
Well I wish it would be that, my signal goes from -63 dbm 25 asu(80% of the time) to -81 dbm 16 asu.
Just after my post, I called one of my friend working in carrier terminal validation.
What he told me was, 2 options:
- Same bug was on the htc cruise, bug got corrected after a fw update.
- Some of my carrier radio are buggy and 3g goes over gsm.(SFR/VOdaphone France)
I bet for the first option since I had the problem in various places since I didn't want to ask support for nothing and get busted for a " feeling and not facts" (did the test in 3 differend location 80 tests in total(I used to be a tester....).
I will update the topic if I get news about it

You shouldn't accept it - but most people don't have this issue!
It's unlikely to be a "bug" per se, because otherwise it would be endemic behaviour, so it's either:
1. Your physical device (get it changed!)
2. Your network.
In addition, just an FYI in case you've got the new Sprint Hero, but most CDMA networks (including Sprint) do not support simultaneous voice and data. I've no idea what happens in practice on Sprint, but I'd imagine if you were actively using data your voice calls would get diverted to voicemail unless Sprint automatically suspends data when a voice call is pending.
Regards,
Dave
You're on SFR?
OUCH!!!!
Sounds like you have a nice strong signal, but is it 2G or 3G? (do you see a G, E 3G or H at the top of the screen?
if you see G or E, it's cos you're on 2G, If you get 3G or H, it's on 3G.
And yes, there were a few issues with the P3300 and the cruise, but they were mainly on Bouygues, not so much on SFR.
There's nothing known of on the hero, and as SFR sell the Magic, i would have thought they would have ironed out any issues already...
Hi,
I'm mostly in HSDPA or 3G.
I still have contacts with people at SFR (used to work there till recently) they might share a bit of info.
Idk if yours is CDMA or the GSM one but on mine (CDMA) under the mobile network settings, I have the option to switch the mode of operation to ether Hybrid, EVDO only, and 1X only. Now, I know how Sprint's network works, not sure if it's the same for any other networks but if I set it to Evdo only (3g) I'll miss all my calls because Sprint does voice over 1X. Hybrid mode does EVDO when you're using data and switches to 1X when you're doing voice/sms.

Regarding this and your suggestion that 2g and data will result in missed calls, Can you suggest how to avoid this happening? I live and work in the country and only have 2g, so have found quite often people have mentioned my phone not even ringing- straight to answer phone. This explains it.
Nice to know, but annoying if I can't solve it- I run a business and my phone is very important.

Hi, I'm on hybrid
that is what i hate about hero, it is really great except for the fact that it switches from 2g to 3g without notice. i want it to be permanently stuck in 3g for faster downloads and mms, but when it uses 2g, i cant send and receive mms and surfing the web is slow as heck! im still looking for an app that would permanently put the device in 3g just like with winmo it which you can use wcdma ONLY.
cheers!
If you use AnyCut, you can create a short cut by selecting:
New Shortcut->Activity->Phone info
This will create a shortcut on your homescreen which beings up a hidden "engineering" screen on which you'll find an drop down for "Set preferred network type" where you can select WCDMA only.
Regards,
Dave
alternatively, open the phone app
dial *#*#4636#*#* and select phone info
scroll down and set it to WCDMA only.
does the same thing but saves installing an app.

That is not specific to the Hero. The fact is, every carrier's 2G network has better coverage than their 3G network. When the phone cannot detect strong enough 3G signal, it jumps back to 2G network. The idea is that slow data transmission is better than no data transmission at all. Many smartphones have the option to lock the mobile network to 2G only. One advantage is that it gets better reception, and another advantage is longer battery life (the 3G chip eats battery much faster than 2G).
If you instead lock the phone to its 3G network. The first thing you will notice is that battery life is significantly shorter. And chance is that you may be getting very spotty reception, because you are not allowing to phone to switch to 2G when it gets no 3G signal. When there is no 3G signal, forcing the phone to "3G only" mode won't give you faster download, it gives you no download.

true true. i usually charge my phone everynight though. problem that i have with 2g is that i cant send and recieve mms and yeah data connection is slow. in our place 3g signal is ok. i also lock my topaz for wcdma only. but it is ok that it switches to 2g in low signal areas.
Thanks!
You actually use mms?
Wow, they do exist.

What NOM1 Networks are there in the UK? I only get 2g in my area (booo) and could do with an operator that works right. T-Mobile forums suggest they still have an issue
Hi
I've checked it with Hero running in PlusGSM in Poland.
Regardless if I select 2G/3G or even "WCDMA preffered/GSM Only/WCDMA only" setting the phone is not available for incoming voice calls during data transfer. Every time when I start internet connection (example: SSH session) I'm not available for incoming calls. At this site I do have both strong 2G and strong 3G networks.
I would like to mention that a few days ago I've swapped Samsung SGH-i600 (WinMo 6.0) for HTC Hero - so I'm using the same SIM card in the same network and the same place. SHG-I600 was able to perform both data transfer (on 2G) and voice (on 3G) on the same time. HTC Hero is not...
I wonder if this is 'feature by design' or a bug in software?

Vibrant takes forever to switch between 3g/edge

Ok, first off my Vibrant has flat out awful reception.. fluctuates randomly between 4 bars and 0 bars on 3g and sometimes cant get more than 1 bar 3g in the middle of an HSPA+ city(Memphis). Its not a bar display problem, sometimes my speedtest shows download speeds as low as 150kbps. If that wasnt bad enough it takes forever to switch between 3g and edge, by forever I mean sometimes a full 60 seconds+ and if Im running a data using program (Pandora for instance) it sometimes refuses to switch at all... Is this a known issue or is it just my phone?? I know my G1 did not have these issues.
Try doing a master reset on your device.
If the master reset dosen't work, you might reflash the full stock rom from the android dev section. There's alot of people that have been reporting substantial increases in their reception and connection speeds.
And if you think it takes a long time to switch b/t 3g and edge, you ought to try owning an evo for a month. It takes FOREVA to switch the 4g radio on and off, at least 3 min for me, takes about that long to turn it on after a reset too.
Just because you're in a HSPA+ city doesn't mean you're on the HSPA+ network.
If you're having problems with it aquiring the 3G network try a new sim.
The G1 has mediocre reception but it is aided by the fact that the antenna is at the top and not the bottom like all other phones.
Bump,
I am actually having this problem too, I have tried a factory reset, I also tried reflashing the T-Mobile stock fimware, but it has not helped. I have good 3g and edge reception where I live.
Oh yeah, I am using ATT on the vibrant.
When this happens (ie. not switching between network or slow switch time), you can trigger airplane mode and then undo it and the phone will pick up the right network or switch network faster. For example, if use 2g network is checked, it will enter Edge, etc.
I see exactly what you guys are talking about, locking it on 3G will fix this right up. I was driving down the freeway and I KNOW I was passing 3G towers, but the Vibrant stayed on EDGE for way too long. I locked it on 3G and I never lost the signal and it was 4 bars for nearly all of the trip so I know 3G was there, it just wasn't switching back fast enough.
Looking under the Samsung debug mode, the Vibrant will hold onto 3G until -115 Recieve power, which is basically -115dBm under the Android network menu. Of course over -101 RSCP, it will show 0 bars so it's hard to know when reception is acutally really bad.
It should show -0 bars at -113dBm, 1 bar until -101dBm, 2 bars until -89dBm, 3 bars until -79dBm, and 4 bars until -51dBm.
just disable the extra frequencies from service menu and it will be super quick.
I'll try that, at any rate it should be remedied by Samsung.

Are you talking about locking it to 3g or something else?

I'm pretty sure hes talking about only having it on 1900/1700 (combi bands)

If the master reset dosen't work, you might reflash the full stock rom from the android dev section. There's alot of people that have been reporting substantial increases in their reception and connection speeds.
And if you think it takes a long time to switch b/t 3g and edge, you ought to try owning an evo for a month. It takes FOREVA to switch the 4g radio on and off, at least 3 min for me, takes about that long to turn it on after a reset too.

Does it matter if you flash from nandroid backup or oden?

That's an unintuitive user interface. sheesh.
Looking at Wikipedia, it looks like TMO uses 1700/2100 WCDMA and 850/1900 GSM (2G/EDGE). There's also a WCDMA 1900, but according to what I'm reading, TMO doesn't use WCDMA signaling on 1900, just GSM/EDGE.
To try it, go to the service menu using the steps for 3G locking and select 1700 only instead of WCDMA ALL. Then go back using menu/back (not the back button) twice and go to Combi Bands and select WCDMA 2100. That should enable just 1700/2100 WCDMA 3G service. Turning on PCS 1900 does seem to get me an EDGE connection. Enabling GSM 850 ONLY gives me emergency calls only, so it might be worth keeping on for 911 calls. 850 goes further so it might have service when the others don't.
I don't get 3G service in my basement, for example, so I would like to keep EDGE enabled. Hopefully enabling just the bands that I would use will help keep the search times down.

To really get a full re-flash, you need Odin right now. It should be possible to do it without Odin now, but I don't know if anyone has put together a stock ROM that way yet.
I didn't see any difference in speed/stability with the stock Odin flash, but others might have. It seems to depend on the network more than the local stuff.
Band IV 1700 includes 2100Mhz so you don't have to enable it. From what I can tell, no.. combi-bands doesn't do much for the slow 3G requisition. I'm just going to lock it on 3G when I'm not at home.

This didn't work for me. I would do this, and it would only work changing from 3G to EDGE. But, from when I would put it on use 3g, it would first change from airplane mode to EDGE, then take around 1 min to change to 3G.

How do I disable the frequencies? I can only seem to enable them.

Can I turn off HSPA to save battery in a low signal building? (Bell Mobility)

My phone is fighting to find reception all day, and it does a number on my battery. Is there a way i can force the phone to not go on hspa and just use 3g, or 2g or whatever? Dont need internet access at work, just calls. thanks
Settings>wireless n networks>mobile network>use only 2g networks
Thats what u need

This phone is only capable of 3g not HSPA+ however, we can go up to the threshold of 7.2. You can only turn off the 3g and will only get edge from the comment above.

The OP's thread title says that he's in Canada and using Bell Mobility not T-Mobile.
http://www.simplymobile.com/wireless/data-device-details.asp?PhoneID=1230 says that it does indeed support HSPA.
And HSPA != HSPA+ (I believe.. would make sense since theres two difference names to it)
@Singhman: 98classic said it wrong. It's in Settings -> Wireless & Networks -> Mobile Network -> Use Only 2G Networks

Im pretty sure i read his post correctly he only wants to use 2g and 3g.... however with most people confusing HSPA and HSPA+ i just guessed he was referring to HSPA+
bell mobility's network does not work on edge (2g). it is a 3g network only. the bell version of the phone shows the option to use 2g, but people using a bell sim can only use 3g.
i have the phone unlocked and on the rogers network and while my phone will switch to 2g when rf is very low, i cannot manually set it to lock to 2g with the stock rom. i have flashed to the jm6 rom and this one gives me the option to switch to 2g and lock it in, but i have issues trying to manually switch back to 3g when i do this.
if you are in an office with poor rf strength, try leaving wifi on so that your data connection will not have to work as hard to maintain a connection. thats what i do when i get home and i find it eats less battery.

No. use the app "APNdroid" @ http://www.appbrain.com/app/com.google.code.apndroid
Leaving Wi-Fi on without actually being connected to a Wi-Fi network actually drains your battery since it scans for nearby WiFi networks especially ones that are public and alerts you.

On the Vibrant, HSPA, HSDPA or whatever are still listed as 3G and not H. The OP said HSPA not HSPA+

if the op does want to totally disable the apn then apndroid will work but i wont use that kind of stuff as i seem to have all kinds of issues after installing apps like this. i am sure it works well for some, but not for me.

I wont continue this any further but he wanted to force it to stay on 3g or 2g and not hspa..... thanks have a great day! (see the part i highlighted in yellow in my previous app)
To answer the op's question maybe you can use Tasker to set up a task to turn off data at a specified time during the day, but its a paid app.

and i didnt say to leave wifi on without being connected to a network, i said if you are in an office all day to leave it on. i was implying that if someone is in an office all day they would be connected to a known wifi source. i do this every single day and it does not use more battery then leaving 3g on in a low rf area.
at the end of the day the op did ask for a way to turn off data completely so the apndroid app is one way to do this.

Yah unfortunately i have a T mobile branded Vibrant so its hard to tell what has been changed between ours and the one for Bell.

Miss / Straight to VM Calls

Majority of time calls go straight to VM . I am missing ALOT of calls.
I have tried different roms .
Running on Metropcs ( T- Mobile ) Network. Latest Firmware ( Global_V10.3.6.0 ) .
Within Mobile Network settings, VoLTE is on. Preferred network type set to LTE/TDSCDMA/GSM/WCDMA. Wifi Calling is OFF .
Really love this phone, but I don't know what else to do! I've browsed the forums for answers as well as Google .
Anyone else run into similar problem ? Any Suggestions ? I've attached a screenshot of my phones settings aswell
Thanks !
In SIM card settings, switch to 3G.
You'll get HSPA (showing a 4G icon) and should get better signals where your Tmobile LTE service did not work.
Finally, download the Network Cell Info Lite app from the Play Store. Check your radio coverage dB level on both LTE and HSPA.
Report back...
.....
FYI....a healthy Tmobile LTE signal should be around -75 to - 99ish and a healthy HSPA should be anywhere from -65 thru -95dB ( lower the number=better)
In those ranges, you won't miss calls, texts etc and have super fast Internet speeds at all times.

How is it performing now?
It could be handover issues between HSPA and LTE, I get this sometimes when roaming on certain networks. I don't know if it's a phone or network issue. Sometimes I have to lock the network to 3G to keep calls stable. VoLTE is still a mess years after it came out, even on new phones.
