[Q] 4G Not Working at All - Motorola Droid 4

Has anyone had an issue or have any clue why my Droid 4 completely stopped accesing the 4G network? I haven't downloaded anything recently and it's been doing it for about a week. 3G connects fine everywhere but it's like the phone doesn't even have 4G capability anymore. I've been in over 5 different cities with 4G and where I previously got 4G service and again it will only look for 3G. It's the latest Android O.S. completely updated and on the Verizon Network. The phone was rooted.
After troubleshooting with Verizon's folks they replaced my sim card and then did a hard reset of my phone both to no avail. Still connects 3G everywhere fine but no 4G anywhere.
This is driving me crazy because there's seemingly no explanation for why this happened. Is it feasible that its ability to get 4G just stopped for no reason?
Any comments / suggestions would be greatly appreciated... I've had this phone for over a year and a half and I love it...:crying:

Perhaps you changed the network mode to only GSM?

[Q] Please help me, no 3g, then no data at all

I bought nexus one from my friend.
I am currently using HD2 with 3g data.
When I plugged in my sim card to the n1, it only worked with edge.
So, I seared internet for some information and I found out something about "*#*#6436#*#*" and change the setting to WCDMA only. Then the phone got no signal at all, so I changed back to WCDMA preferred. Then I did ping test but it did not seem to work very well.
Then I played with some APN setting and I realized that I lost data connection completely (phone still working)
I have tried to reset the phone but no luck.
Can anyone please help me with the problem? I am using T-mobile.
Thank you.
Pull your battery, and look at the back of your phone. At the top of the dark area there are numbers, look at the PB or FCC ID numbers. If they end in 9110 then you have an AT&T version of the phone, and the hardware will not work with T-Mobile's 3G service...

are you in the USA? you need to list your location. it is likely that you purchased the wrong version of the nexus one. there is an ATT version and a tmobile version. each only works with the proper 3G. so an ATT n1 on tmobile only gets edge, and vice versa. check which version you own.

[Q] 4g data problems at home

It seems I have very good 4g signal at my work but when I am at home, it gets stuck on either 1x or 3g, according to sprint, there is 4g coverage on my house.Does anyone have problems with 4g not working properly? Its getting me annoyed since I use hotspot at my house. Any suggestions would be helpful.
I've noticed it'll show 3 bars of 4g at home, but if I actually start browsing it drops to 3g. My friend had done nothing but complain about sprints network so I am just assuming it's their problem.

I'm having the same problem! My friends iPhone gets better reception, and we both have Sprint. He gets LTE at my house in my office, but I get 3G or 1X. It's very frustrating. I may return the phone, or leave Sprint altogether, as I didn't have these problems with my Verizon Note 2.

I have used sprint chat with an agent and followed every troubleshooting method and still 3g. I will check the store to see if I can exchange it for another phone or see whqt happens
Could just be a week signal. Note that the signal bars on your phone are NOT for 4G. Check out this helpful write up over at S4GRU could help you determine what is up once you check LTE signal levels.

Lg esteem help

Does anyone have any knowledge on how to work with the Network Configuration? My LG ms910 from metro works normal, but if for some reason my phone goes through a coverage area where my signal drops from LTE to CDMA, it stays CDMA (3G) until the phone is restarted. I've tried using every shortcut from any cut that had anything to do with network, internet and data and many others. I've also spent countless of hours researching and I just can't figure it out. There must be a way to change your connection manually without restarting your android to switch from CDMA back to LTE when in LTE coverage??
Please I beg anyone who understand of this situation to help me come with a solution besides tossing my ms910 out and getting a new phone?

HTC One M8 reception worse than M7

I just got my new M8 today. Did the update, activated it, did the profile & PRL update, etc.
I am constantly getting the message that I am roaming on data. It seems to go back and forth between roaming and not roaming. Even outside I only get 1 bar of LTE and the LTE signal is a good 10dBvm worse than my old M7. My M7 never switched to roaming in the same location.
Anyone else noticing worse reception on this phone than the old HTC One?
I'm having the same issue.

I was worried bout the same myself. In the office with the M7, I wan't able to get LTE, but luckily with the M8 I am able too. I would have your phone checked at a corporate Sprint Store to see if it's faulty

I had the same issue yesterday when I upgraded my radios to the new version (1.54). I was stuck in 3G roaming at my house which was normally low end LTE service before the upgrade. After flashing the radios I did a Profile and PRL update using WIFI, then restated my M8. After the restart I am back to having LTE coverage floating around -90-95 dBvm. I also notice that if LTE fails to connect swithing airplane mode On/Off helps as well as dialing *18 from the dialer. Hope it helps.

I already did the profile/prl updates, and my phone isn't stuck on 3G. It will go 3G roaming, then 3G on sprint, then LTE. Seems to not be able to make up its mind. On my old phone it would usually toggle between LTE and 3G in this area, but NEVER did it go roaming. Even when I'm on WIFI I still get the annoying roaming notification in the notification bar every 5 minutes.
I also noticed my WiFi download speed on wireless AC is significantly worse than my M7. I used to be able to get 70mpbs on a speed test, this phone won't even break 12mbps. When I first turned the phone on it would only work on WiFi for the first 3 seconds after connecting and then it would stop. I had to keep connecting and disconnecting to WiFi to limp the software update download along. After it updated it at least stays connected and working on WiFi, but a lot slower than my old M7.
This phone was purchased on a SWAC account so I'm not sure if a Sprint store (which is 40 minutes away for the nearest one) would swap it for me.
Moved to Q&A...all questions should be posted in Q&A.

Nexus 6 connectivity/LTE issues

With Verizon I started to have drops in signal all together and rarely could connect to 4g. I went and activated a sprint account and it first things seemed fixed. Now 24 hours later my phone will not connect to 4g even though signal monitors show a LTE connection, I have to force a 3g connection to have internet. This is happening in areas with great 4g coverage for both providers. Would you consider this a defective phone? Has anyone else experienced these issues? Any help would be great both Verizon and sprint seem to be at a lost about what's causing this.
