    As of a few days ago, my S5 won't hold a 4g LTE connection for longer than a few minutes. (It worked perfectly fine for several weeks prior to few days ago). The only thing I can think of that I did was do a Verizon roaming profile update (or at least try to since until reading other forums I didn't realize I don't need to do the *228 updates anymore since handled now by 4g sim card). Could me doing the *228 update cause my current problems not holding a 4g connection? I have a support ticket in with Verizon also (and they can actually see my 3g usage going way up vs. 4g since few days ago), but I figured I would check with my usual forum experts in the mean time as well.

    Just a note when I power off my phone and turn it back on, I do initially connect to strong 4g LTE signal - but it only lasts for a few minutes before falling back to 3g. I have also removed and reseat my sim card with no luck via that approach. Thanks for any guidance!

    This is happening to me and quite a few others on the Sprint network. There is no ETA for a fix. To be honest I don't want to use this phone on 3g. Called me spoiled or whatever but the phone, in my opinion, is pretty crippled on it.

    I hope they find a fix for what is causing all the disconnects, but paying 650 for a 3g phone isn't worth it to me.

    See what happens.

    I agree that it's not right only getting 3g with such an awesome phone otherwise. Hopefully Samsung figures out if this is a carrier issue or a phone issue and get it fixed quickly.

    I'm with Sprint and have no problems. When not on wifi I would say its on LTE 95% of the time. There's one or two areas within a 50 mile radius where it drops to 3g. I'm getting at least 15-20mbps

    I've tried toggling airplane mode also and it does work initially, but still only holds 4g connection for a few minutes. I'm in a very strong 4g area and used to get great connectivity until about a week ago. Just can't figure out what changed. Wonder if my sim card could be bad? Or I'm still wondering about whether me updating my roaming profile via *228 could have triggered the problem on Verizon network.

    I'm having the same issue with my S5 on Verizon. It seems to happen most when I'm traveling in the car. Toggling airplane mode works for a few minutes as was stated here already. I'm bringing it back to the store tomorrow and making them give me a new one.

    It is a Sprint tri-band phone issue. Their phones can't do the handoffs very well... Airplane mode toggle is the work around but yeah that is annoying.

    I was having the same issue as well with my S5. Samsung kept saying it's the network Sprint said it was the phone. Now from what I'm hearing Samsung is going to send an update to correct this issue, it does have something to do with the phone. I switched my S5 for the M8 and have not had the issue since. So I tend to believe it is the phone that has the issue. I am on LTE with my M8 95% of the time and love it.

    I'm also having this issue with my SM-G900W8. I'm on Virgin Mobile in Canada and I'll get LTE in my area for about 5 mins. It will then proceed to drop down to 2 bars of LTE and kick itself back down to HSPA+. Done all the normal stuff like a Sim swap and factory resets. Only thing I'm able to do is go into the wireless and networks settings and manually put it down to WCDMA. Hopefully this is just a quick software patch.

    But you said you have LTE pretty much everywhere you go right? The issue is people who are on LTE but travel to a weaker LTE area (or non LTE area) then drop to 3g. After that the phone won't jump back to LTE after they leave the bad area (even if a good LTE signal is around) without the toggle.

    Ahhhh I see. I'm in Dallas which is a pretty big city, there's an area or two where mine drops to 3g but then jumps back on to LTE when it is available. My point was that I don't think it is a carrier problem.

    Almeuit just spoke the main reason why I am leaving Sprint. Toggling airplane mode at random intervals throughout the day is not on my list of things I like doing.
    At first, I was patient. But when the problem persisted after 4 months I had enough. I was having this problem on my Moto X, and my Nexus 5.

    However, to the OP: From what I understand, the phone would have made that update anyway. You just hurried things along.

    I am highly inclined to think it is. I had the same Sprint problem on 2 different phones. Moto X and Nexus 5.

    It isn't just a Sprint issue. I'm having the same problem on Verizon as well. They're sending me a replacement S5 due to the combination of issues I'm having.

    I'm on Verizon also, so will be interested if your replacement S5 solves the problem. Good luck.

    So I've Written this out a Hundred times but it's something. Called CSFB. https://www.google.com/url?sa=t&sour...EXGUJTfy_7IiOA that's a link to a PDF fro. Qualcomm discussing Future Network envision and discusses the problem of CSFB. And Here is another PDF from a Consulting Firm that was employed to access the situiation of the network enhancments for all carriers in Us, and their determination of warning the Carriers CSFB was ... Well... ****ty.
    https://www.google.com/url?sa=t&sour...ZrAZv-q8muZ0gQ

    So, hope that helps u understand situation. Best I can say is Ride it out till your Carrier works out a deal the the Incumbent provider of your region to offer Csfb. Or the tech gets upgraded by either Tower CSFB, VOLTE. Or Private in home Femtocells. Cheers!

    That's why I left within my 14 days and went to att. Sprint told me there was no fix in the near future, and that after there entire network rollout is complete that they will try and fix it. But no guarantee that it would get fixed...

    Your Correct. In my Case, Verizon is the only other carrier of the HTC One Max, and for a single line with them and enough Data so I won't be getting myself into trouble would have been about 140 to 150 a month. Yeah. So Sprint at the 100 a month was the clear option. I don't wanna change phones. I don't like any of the other ones. I had boost mobile on a old ZTE warp (barely 3g) before this for 45 a month. I am also very hopeful of a M8 boot to a "Max" style device in September October. Which I believe with all this hooplah with be free to me even being short a few months of 1 year. I've always preffred HTC products. Back to the days of the HTC touch Pro, Touch Pro2Diamond with full querty keyboard. Lol. I don't mind other stuff, just not a fan of the shackles of Apple, and IOs. Ultimately, it's what you think are your best options, and everything is Personal preference. It's your money. So don't ever feel guilty if you want to spend it elsewhere. Now, don't feel hurt if you threaten to switch and they dont give a hoot. Corperations may come and go. But the men at the top stay wealthy.

    I just noticed today on my way home I was on 3g, fifteen miles in a large city with LTE. I toggled the airplane mode and nada. Came home and restarted and got the LTE back. Is there a way to toggle?

    Well I thought I had the problem but I came home and chose not to connect to Wifi to do a test. Was on LTE, went into a dead zone in my house. It dropped to 3g. Then went away from dead zone and LTE came back. But when I lost it driving home it wouldn't engage back to LTE after it was on 3g. When I connect to Wifi and it drops Wifi when I go to the roof deck it goes into LTE mode.
