Does anyone have bad call dropping experience? On my AT&T Tilt with the HTC Rom running Windows Live for Push Mail (hotmail account), my call drops a lot; I looked at the screen every time the call dropped, and it seems that 90% of the time the "3G" icon was trying to connect and shortly after it changes to "H". Does that means the data connection on my phone some how caused the voice call to drop?
I've installed the Kaiser Tweak that turns the data connection off after 1 minutes of no usage, and I saw the 3G and the H icon switched quite often. Does that have anything to do with the call dropping?
the H icon shown only when you are connected to the internet, otherwise it stays 3G although you are in the HSDPA coverege
Ever since I used the Kaiser Tweak to disconnect from the network after 1 minutes of no activity, the connection message (the pop up message from the title bar saying "Connecting to ..." ) shows up quite often. This is probably due to my Windows Live tries to sync the email. Sometimes when the call was dropped, that connection message shows up immediately after the call drops. Could it be due to the fact that the 3G signals was not strong, and it was switching between 3G and EDGE that causes the call to drop?
I've also seen my call drops sometimes when transits between 3G & Edge, not sure if it's related...
I know HSDPA does simultaneous voice and data, but I'm not sure about edge. If you are on UMTS or edge and the call drops when you connect to data, its prob bc they will not do voice and data at the same time.

I'm in San Diego, CA this weekend for a NPPL event (national pro paint-ball) and sitting here in the hotel tethering my laptop to my Tilt. So between beers (and NO it's not the beers talking now), I had to reset my Tilt so I pull the USB plug and noticed within a few seconds the H icon on the taskbar changes back to the 3G icon, I thought nothing of it.
I soft rest, plug in, noticed 3G, did a few things, still 3G, activesync complete, still 3G, fire up Internet Sharing and press Connect.... BAM! HSDPA icon and H icon within a second or two. So I further the test.... unplug, replug, start internet sharing, stop it, plug in/plug out.....
EVERY SINGLE TIME... H for tethering, 3G when not tethering.
Now of course, this could just be a total fluke, I will have to test again in another environment and see if I can reproduce. Also, I was able to get both 3G and HSDPA when the Tilt was not plugged in or tethering so I'm not saying that the device only gets higher speeds when tethered.
What was so interesting was the timing, if it was a fluke, it was a very cool one!
Has anybody else ever seen this before?
One side note... San Diego is the home of Qualcomm, the manufacturer of the processor powering the TYTN II/Kaiser/Tilt device. I know this has nothing to do with the spookiness of the icon above but now it's the beer talking, so time to sign off.....
When I'm not actually using data, my Tilt shows "3G". When I do anything that requires data use (web page, email, etc) it changes to "H". Sounds about like the same thing you have going on - when you're phone's not using data, it's sitting at the "3G", but when you're tethered, and using data, it's showing that "H" is in use...
This is normal.
On mine, when I don't have a data connection I have the 3G symbol, when I activate a data connection it will access the fastest (HSDPA if available).
I have noticed that if the HSDPA signal is weak (distance = greater packet rejection) on pure battery I only get a 3G connection, then when a cable is plugged in (power or USB) the extra power available while charging, increases the signal strength and I get HSDPA.
Maybe it was the same at the location you were.
That is the way "H" works. The cell you are connected to offers 3g and throttles up to "H" when data is tranferred. If you had accessed the web on your device when untethered, it would have changed to H as it transferred data also.
i know you asked about tethering.
but my tilt will jump in and out of HSDPA and 3G constantly during any data usage, tethered or not. However it is dependent on location, as in San Diego downtown I get H the whole time(that i paid attention to it), and when I was in North County, 20-30 miles north of downtown I get 3G/H in and out even during constant data transfer(streaming audio)

Never really noticed it before, I just sometimes notice the H, I never put it together that it ramped up during data transfer only. thanks for the info...
It swaps to HSDPA for only as long as it needs to download what it's working on... when you tether your phone you're doing lots of data, so H shows up more.
If you have HSDPA enabled, you'll see it using HSDPA when you use standard data connections from the handset -- but keep in mind, HSDPA & 3g are harder to get good connections for then Edge/gprs... I get HSDPA in my living room, but I swap between 3G/GPRS when I browse the same websites from my basement -- due to the weaker signal strength...
Hello,
I have a verry weird problem with my Tytn 2.
Most of the time when people try to call me, the phone doens't ring. the only thing i see is a small incomming call icon on top of the screen and the screen turns on. after that i get an sms message from my voicemail. (They get redirected to it)
Sometimes it just works well.
Dont know what is going on, but it is verry annoying. i miss a lot of calls every day.
Maybe anyone know the issue?
Btw on a sidenote, i check my Gmail every 5mins (1min disconect when idle) but it seems to consume a lot of data +- 15MB a day. Only email checking!!
Anyone who knows how that come?
Thanks!
r u on a 3G or 2G coverage?
If on 2G, some operators do not allow data and voice at the same time. So if you have your Internet connection on at almost all the times, your voice calls will automatically be switched to VMail.
But if you have a 3G connection. dunno.
as far as the net usage, do you download ALL the message? try loading only the headers? Do you also download the attachments? all these rack up.

Well i think i can select that at the menu 'Band' it is configured as 'Auto'
Can chose:
Type network: Auto, GSM or WCDMA
Select GSM/UMTS-band: GSM(900+1800)+UMTS(2100) or GSM(1900+850) or UMTS (2100+800)
i know my provider supports 3g
Or is that the wrong menu? and settings.
Thanks for the tip on the email. Attachments were already disabled. but i chosed to download all tekst and no images. But now i selected it to header only, will monitor how it goes.
Hm, maybe some more ppl with input?
i still think it has something to do with the internet connection that is active.
My Kasier switches between 2G and 3G depending on coverage. Based on the answer you already got above, this might explain the "random" nature of missed calls:
If your coverage at a point in time is 2G and an incoming call happens at the same time as a scheduled email download, the call gets redirected.
If your coverage is 3G, the call comes in normally.
I hate push email on my phone (it's a control thing) and pull email down when and if it suits me!
Hmm dunno if its a coverage problem i travel a lot, and today i missed 2 calls again. Damn its getitng annoying! maybe i need to try a hard reset?
Hm most pll say that the phone rings two times, and then switches to my voicemail. But i dont hear anything, only see a small phone icon in the top bar.
Rings twice and then voicemail is definetly you using data connection when someone calls.
I have had mine not ring and go to voice mail several times. Once when it happend, I called it myself, and watched teh phone, and I noticed that it thought I had on a BT headset. My BT was on on the phone, but I did not have a BT headset on. So, I think it was sending to BT, but there was not BT. I have started turning my BT off if I am in fact not using a BT headset or other BT device.

Hello
When i set internet to 2G i have no internet connection during a call. If i set it to 3G i do have internet during call.
Is that normal?

Yes it is.
This might not be really relevant but if you actually do want internet connection during a call try one of Haykuro's H Roms on his google page. Reportedly they allow browsing while talking to someone
I don't really want to change the rom there for.
But as it works on Haykuro's builds, maybe a developer could make it work on other builds.
Last time i checked it has to do with the frquencies *sp
Which, in my opinion, no can do

Hehhehe! That's what so great about GSM 3G...data & calls simultaneously! You don't have to have a certain kind of ROM for data to work during a phone call, lol... I have noticed that it will sometimes switch to no connection during a call which would cause a drop out in data. The way this best remedied is to set the phone to 3G only under phone info settings. When I have it set to 3G preferred, I make a call and sometimes it will switch to 2G and therefore, losing my data connection (2G doesn't allow data & calls simultaneously). This does this even when 3G is still available. So if you're in a good area where 3G is prominent, switching settings to 3G will improve many things, just not your battery life.

This is normal. 2G or EDGE cannot handle calls and data at the same time. 3G can handle calls and data at the same time.
First off, I can make outgoing calls 100% of the time, and never have any problem except a split-second delay (as expected with VOIP)
Receiving calls though......
First, wifi calling randomly turns off, with a note I find later about "wifi calling is not available at this location" ---- yes, I have poor reception, and I know wifi calling requires an always-active GPS signal so rain or clouds can kill it --- but it never turns back on once the storm/cloud/whatever is gone, it stays turned off until I manually turn it back on.
Second, even when it is turned on, I will randomly get no notification - no ring, no vibrate, the screen stays black, and no "miss call" notification, I just get told later that someone tried to call me and it went straight to voicemail.
Third, when it does register an incoming call, I will swipe to answer and the phone app will... kinda half-freeze... it acts like it's trying to answer the call, where the red end button appears, but all the other buttons are greyed out except message. It's in a strange limbo-like state of being answered and not... when this happens usually the other party will connect and can hear me, but whatever they say never reaches me.
Fourth, I answer the call, everything seems fine, I say hello and just hear my own voice echoing, and even though I answered the call, they never connect and end up on voicemail.
I know that WiFi calling is a "new technology" (even if we've been using VOIP for years....) and Sprint hasn't "ironed out the bugs" yet, but is there anything I can do to improve it?
I have tried doing a hard reset on the phone, updating PRL/settings/OS, changing the phone data mode from LTE to CDMA, sprint tech changed out my SIM card for a new one, airplane mode (which doesn't work because it turns off GPS)... none of it works and I still miss a good 60%+ of my calls... any other suggestions?

do u have a vpn active?
plus i dont think GPS has anything to do with "WIFI" calling.
as long as wifi is connected to a proper wifi network, that should be all you need.( other than if a VPN is activated or wifi network is congested/ to many AP ssids with overlapping channels, then it should work fine.)
I did before the hard reset (one-dot), I dont now. so it didn't seem to matter...

Oh sprint. I always had network connectivity issues with them. I wouldn't be surprised if this is something that is wrong on sprints end

You have to have an active GPS signal for "e911 services" --- yes the app claims you can set your location manually, but doing so does nothing and as soon as my phone loses cell/GPS reception, wifi calling goes off and will NOT come back on till reception is restored (also I've used two of Sprints Femtocells and both of them required an active GPS for e911 so....)

yeah.... since about the start of this year my LTE speeds have gone down (though only in actual use! --- run speedtest and magically I have like 50mbps, even though I can't watch youtube even at 144p without it buffering and asking my phone "Alexa Next Track" returns an error about connectivity) Also my reception in my home has gotten worse in the last couple months --- for the last 17.5 years I've been able to make/receive calls on sprint over normal cellular without issue as long as it wasn't raining (yes, I've been with Sprint for almost long enough to raise a child.... they started out as the best carrier in my area, believe it or not), but now even though my phone reports 2 bars (out of like 8 or 10), I recieve almost no calls, and drop outgoing ones very frequently unless I switch to WiFi Calling.
So... yeah... I figured it was actually bad implementation on either Samsung or Sprint's part, but I was hoping there was something I could do to improve it....

Switch telco's... Sprint dropped the ball. They invested in. Winax , then LTE took off. They've been behind ever since
Is anyone able to access the global wfc_ims_mode in the Pixel 4 or any later versions of android than 9? Here is the method I am referring to.
I need to know this because I am currently using an OG pixel and I manually set the Wifi Calling to Wifi Preferred as we know the toggle button verizon offers inside settings is a dud.
Without forcing the global wfc_ims_mode to 2, my phone is essentially a paperweight as all data and more importantly calls and text will always default to cellular which I have 0-0.5 bars of service at my home.
Thanks!
Deeper explanation and rant - cynicism and blame incoming.
A quick summary of Wifi Calling Preferred - There is Wifi Calling, yes I know, that toggle works and is on. Then there is Wifi Preferred, a separate setting that tells the phone it what connection to default to. This is a toggle that was inside of the the Wifi Calling settings that has been confirmed to do absolutely nothing regarding your phones affinity for wifi or celluar. It is not tied to anything on the side of the android ROM, it is just there to create the illusion that it works. It was supposed to allow people to force the phone you have to use the wifi connection over the mobile connection which really help people on the edge of a service area or, in my case, in .5 miles from a Cal State University with a partially obstructed view of a cell tower.
"But I see "Wifi calling" in the top of my phone sometimes and I have never had problems."
1. Yes, Verizon does allow calls to sometimes initiate through wifi and even stay on wifi for several minutes. However, Verizon has set conditions on what a "good connection" means in order to keep wifi routing of calls AND data to an absolute minimum regardless of how this effects the end users call and data quality. Simply put, if we rate our wifi and cell connections from 1-20 with 20 being spectacular and 1 being awful; Verizon has effectively written boundary rules that say a cellular signal rating of 1 is ALWAYS preferred over wifi signal 20. You could be standing next to a brand new gigabit router with google fiber and full signal, but if Verizon thinks it has .005 % of a bar, then guess what? No call! However, Verizon knows that it must initiate the call with good quality so they use the "wifi calling" (comes up on the top of the screen) to start the call, but as soon as the call has begun, and the phone has detected a signal of 1 on the cellular it will perform a hand-off to the cellular network. Icing on the cake?This is a mono-directional hand-off, meaning wifi MUST handover to the cellular but going from cell to wifi requires the phone disconnecting the call. Outstanding move Verizon!
2. I have 0-1 bars of service where I am so if you have more than that you wont notice the hand-off. I run my business through my phone and I was so tired of missed calls, missed texts, dropped calls, garbled sound, echo. Most people will see the "wifi calling" icon in the top of the phone and assume the entire call took place over wifi. Not the case at all. Just trying to avoid the "I have wifi calling on and everything is fine for me". Yeah, how long do you talk on the phone? How many calls are you getting? How sure are you after reading what I just wrote that the entire call, and every call that takes place in your house just simply because you are home and connected to wifi and one time saw wifi calling on the top is actually using wifi maintaining the call through your ISP??
To get around this, here is a method that I still use on my original pixle XL. I am still running android 9 as the move to 10 seems to have move the wfc_ims_mode select.
This is one of the main reasons I still use this phone. Without Wifi Calling being forced as "Preferred", I know everything will route through Verizons service which is virtually 0 where I am. This results in missed calls, dropped calls, and video qualities jumping around between 144p and 360p.
Would like to know also.
i have tried this method on my Pixel 3 android 10 stock and it didnt work.
