Phone intermittently disconnects 4g without notice or warning. What's wrong?

Every so often (sometimes as much as once a day) my 4G connection randomly turns off.  Usually after switching between WiFi on/off.  I notice that it gets stuck in 3G and I will have to manually go into Settings > More Settings... > Mobile Networks > Access Point Names > and check "LTE" back ON.

This is getting really old.  Sometimes I will not even receive any service even if 3G is on.  Data will not send/receive until I go in and manually check LTE back on again.

Is anyone else experiencing this issue?  Any solution?

Others with this same problem have tried with limited success:

  1. Settings > More settings > Mobile networks > Network Mode > LTE/CDMA
  2. Removing the SIM card, leave out 5 minutes, reinsert SIM and reboot.
  3. New Sim card
  4. Getting a CLN replacement phone under warranty.
  5. Returning the phone to Samsung for repair.
  6. Settings > Application Manager > All > Caller Name ID > Disable
  7. Prayer

And unfortunately, for some people none of these worked.  They then lived with the problem or switchd to a different manufacturer's phone (IMHO Motorola is a good choice, but YMMV).

Just curious  do you have unlimited data?

I live in a solid 4G area, but it happens to me randomly as well.

My fix so far has been to just turn the phone off and it normally reconnects to 4G.

I would hate to think Verizon is doing this on purpose.

I was kicked off unlimited data a long time ago.  Rebooting the phone takes much longer than going through settings, but thank you for your input.

I noticed that since this morning my GS3 will not keep LTE conntection for long, even after reboot. I can normally keep LTE connection at my desk at work but I noticed the problem starting at home and along my commute to work as well. I am in the Atlanta area.

Not to add fuel to the conspiracy theory but I also have unlimited data and no other LTE verizon (nokia822 or iphone - tiered data) has the same problem.

    • I found this method caused other issues...such as not receiving service in some areas where Global would.
  2. Removing the SIM card, leave out 5 minutes, reinsert SIM and reboot.
    • Only temporary fix.
  3. New Sim card
    • I'm on my second one...Best Buy gave me a hard time replacing my first one (apparently they're supposed to charge you for it...ha).  I might try this again, but I am skeptical.
  4. Getting a CLN replacement phone under warranty.
    • What is a CLN?  I have Best Buy warranty...I really do not want to send it out for repair or even get a refurb.  Too much hassle.  Would be last resort.
  5. Returning the phone to Samsung for repair.
    • Last resort...way too much hassle.
  6. Settings > Application Manager > All > Caller Name ID > Disable
    • Did this a long time ago.  This bloat-ware caused many other issues that were resolved, but this one persists.
  7. Prayer
    • Ha,

Thank you for your suggestions!

CLN is Verizon's "Certified Like New" program.  Instead of a new phone under the warranty program they give you a phone that has been returned for some reason and has been repaired and passed X number of steps in a quality check.  Sometimes you get a good one and sometimes not.

They say in all conspiracies there lies a little truth.

Were just going to have to keep watching this.

legalkill, thanks for these details. Service looks good in Atlanta. Let's take a closer look at your device. Have you downloaded any 3rd party applications to your device? Some application software can affect the performance of your connection. Try uninstalling a few applications in Settings and power your device off/on again. Keep us posted.
