It definitely seems like it's happening too much to not be some kind of issue. Although I got a replacement and it's working perfectly. Complete 180.

They had it in stores at my local best buy as well as the Sprint corporate store. I was very tempted to return mine and get the gold from best buy, it is so sweet looking.

Very true. I do envy that.

For me they had to let a technician look at it before they determined it was actually defective. Your reps may be a little easier to deal with, the guys here were going to deny my devices behavior until the bitter end. We almost had words.

I swapped for a new m8 and have gotten much better results in Knoxville and Maryville. Lte almost everywhere now and incoming calls actually work! Sent from my 831C using Tapatalk

Took my m8 back sprint today and got a new one. The difference is night and day. LTE the whole way home. Incoming calls now work as well as texts. Might have been csfb, I don't know. The timing was too good to be a coincidence. I am very happy now! Sent from my 831C using Tapatalk

What's the lte file you're speaking of? Sent from my 831C using Tapatalk

On my way home I definitely connected to LTE much more than I have since I got the m8, but the actual data coming through was spotty at best. I never could finish a complete speed test, it was coming and going.

Where at in Maryville were you seeing LTE? I was in Walland when I connected to LTE, though it didn't actually work.

go into the phone dialer and dial *#*#4636#*#* then press "Phone information" then scroll down a little bit. About halfway down there is an option to "set preferred network type" and right below that you can touch whatever it says and a pulldown appears that you can scroll through. towards the bottom is LTE only. edit: beat me to it jorge!

Last night I got the error "Unable to establish a wireless data connection. LTE: EMM-0" This morning on the way to work I set my phone to LTE Only and what do you know! I connected to LTE! Unfortunately I never was able to transfer any data :/ It stayed connected to LTE it didn't switch off, the little icon never spun and I never go to open google.com or whatever it was I was trying to test it with. The only I'm going to truly know if it's the network or my phone is by driving an hour and a half to a city that definitely has CSFB installed. Freaking sucks.

My 3g is jacked too, along with dropped calls galore. About 15 tonight alone. I was under the impression that csfb only affects loss of lte so I'm very confused now. Starting to think I need to get a new device.

Driving home tonight I dropped no less than 10 calls. I'm on cdma only. Wtf

Hey guys I've been reading up on this like crazy since I got my M8, but I'm still unclear on one thing. I'm technically in the Nashville market, but in a city called Maryville, right outside of Knoxville. While using the GS4, Iphone 5/5S, M7, etc I was able to connect to LTE almost everywhere in town. Now that I have this M8 I can't get LTE anywhere. So I take it the CSFB hasn't been installed yet in my area. That much I am clear on. The part that I'm concerned about is this: The device is supposed to recognize that CSFB isn't installed, then kick back to 3G and stay there, correct? My problem is that my phone is going a step further and kicking back to 3G, but then losing THAT connection very frequently (if it ever truly makes a data connection at all) and incoming phone calls are arriving to me with about a 5% success rate. Texts are also spotty at best. So essentially right now I have a very nice wifi enabled device in my pocket. I can't seem to find anywhere in the explanation of all this where 3G will be so greatly affected. This has me concerned that I actually have a bad device on my hands and need to get a replacement. Is there anyone that can definitively tell me that this is a side effect of CSFB and not a bad phone?

I've switched to CDMA only mode exclusively for now. I've found that if I'm going to be staying in one place for a while like my home or my in-laws' home, I can restart the phone and 3g connects and stays connected fairly well, though it's still not 100%. When traveling after that and moving throughout town and moving to different towers, that seems to really cripple any ability to get a 3g data signal, a phone call, or a text, and really truly won't reconnect until I do another restart. Does this sound like CSFB?

Update on mine (if anyone cares ). I've switched to CDMA only mode exclusively for now. I've found that if I'm going to be staying in one place for a while like my home or my in-laws' home, I can restart the phone and 3g connects and stays connected fairly well, though it's still not 100%. When traveling after that and moving throughout town and moving to different towers, that seems to really cripple any ability to get a 3g data signal, a phone call, or a text, and really truly won't reconnect until I do another restart. Does this sound like CSFB to anyone?

I got LTE ONLY mode to work when I was in Knoxville but even then it wasn't reliable. It kind of worked. The data was intermittent.

Is this the kind of thing that happens to all tri band phones if the fallback switch isn't installed yet?

Same story for me. I took it to sprint asking for a replacement and they swear up and down its the network.

Yes but the way I read it it's speaking more on the ability to connect to LTE. I understand my phone disconnecting from LTE and reverting back to CDMA, but it doesn't mention CDMA itself being inoperable, unless I'm missing something. I've set my phone to CDMA ONLY and it absolutely cannot stay connected period. As I'm typing this it just disconnected from all services and is now searching for CDMA again. 3g has worked properly and let me access a simple Web page for about 30 seconds grand total today. The rest of the day it's been working with all its might to just connect to 3G and actually have a working Internet connection. There's no telling how many calls or texts I should've gotten today. This is all happening while I'm set to cdma only. No LTE involved whatsoever. Again I could be reading it wrong but this seems to be something more. I wish someone in my area with a triband device could chime in and say yes mine is the same or no that sounds worse than mine.
