Hello all,
My spouse and I each recently got Samsung Galaxy S5 phones and we're finding that for one of our phones, the signal keeps dropping from 4G LTE to 3G, even when we're at home on Wifi. It seems to be happening randomly from one time a day to multiple times a day. Toggling Airplane Mode on and off usually brings it back to 4G but eventually it will go to 3G again. We live in MA in the area code of 01886.
The signal strength in our house is not very strong (usually 1-2 bars max) so I think that might be why it keeps going to 3G but I would think it should be the same for both of us. I've been reading online and it seems to be a problem with the S5 phones themselves rather than network signal. The only option seems to be to replace the phone but according to some that does not help. Restarting the phone does not help either,
Are there any fixes available for this problem or should we go to a Verizon store and try to exchange the phone?
Are both using the same network mode? Global or LTE/CDMA? Are SIM cards in the devices the ones that came with the phones or from a previous phone?
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
Also have you tried switching the SIM cards to see if the phones work better or worse or the same?

Thank you for the replies. Both phones have a network mode of Global and both SIM cards are brand new and came with the phone (we were upgrading from very old flip phones).
One interesting thing we've noted is that the phone we noticed that kept going back to 3G would often do so when in one of the back pockets in our jeans - even the other phone would go to 3G that way. The signal is very weak (usually 1 bar) in our house but could a somewhat tight jean pocket cause the signal to drop to 3G? Why won't it go back to 4G unless we toggle Airplane mode?
Change your network mode over to LTE/CDMA as Ann154 posted and this may help somewhat. However I don't feel you have any real problem with your phone. Your problem is more to do with being on the edge of a weak 4G signal and when using Airplane mode the receiver is trying to go to the 4G signal and then dropping back to 3G. As to tight jean pockets your own body can cause signal loss in an already weak signal area. I would also do the switching of sim cards for signal improvement testing and see if there is any increase.
Thank you for the advice. I'll try changing from Global to LTE/CDMA and see if that helps. Would this have any negative impacts? I'm not planning on traveling out of the country any time soon or anything so I'm thinking no.
Sometimes I've even noticed that it doesn't say "3G" even, it just has some bars. I'm assuming this is 1G? But almost all the time when I reconnect by toggling Airplane mode it goes back to 4G but it seems to never switch back from 3G to 4G without this toggle.
By switching SIM cards, do you mean getting new SIM cards or swapping them between the phones? Would the phones still essentially be the same except that the telephone numbers would be swapped?
I'm thinking of going to a Verizon store and seeing what they say too - maybe they can tell if my specific area is far from an antenna or something. I'm hoping it is just a weak signal issue but one phone seems a little more affected than the other. I really don't want to replace the phone and from searching around, that doesn't always solve this problem.
It is a problem with the phone itself. Many S5 phones have this issue. Mine will go from 4G LTE, to 3G, to 1X. I have taken screenshots of locations using Google Maps to let Samsung reps know it isn't a location issue. The Samsung reps are clueless as to how to fix. The last "suggestion" I got from Samsung was to return the phone for a new one. Good luck. I'm a big fan of Samsung, but this S5 might be the worst phone I've ever owned.
The SIM cards will be swapped between the phones to see if signal improved. The phone will remain with the same settings as before and the only different would be if you had change the phone's number. If you still feel you have a problem you can take the phone in to a Verizon store.
Thanks again all for the replies. Changing the SIM cards didn't seem to have any major affect - both phones would still go to 3G (especially when in pockets) and one seemed to do it a little more than the other (non-scientific observation just over casual usage).
Last night I left the phones on my nightstand from about 8pm until 7am the next morning and the signal was still 4G when I picked them up. I'm going to watch them carefully today and try to keep them always out on a table or something to see if the signal degrades to 3G at any time. Due to the above, I'm cautiously hoping that it is just a weak signal causing the 4G to 3G drop and not anything with the phone (since I've been finding from research and this thread that the S5 phones can be a problem).
Can putting a phone in a pocket really cause that much of a signal degradation?
What exact impact does changing the network mode from Global to LTE/CDMA do? I thought Verizon was all CDMA - maybe I am not fully understanding.
Again, thank you for all the help.
Go with the sim cards that came with the phone as there was no basic change. As for the signal level on the nightstand, think of it as a person breathing. Hand over month..problem, no hand = no problem getting air. Now your phone's antennas need to receive signal as well. Your body, hand, inside a car, tree leaves and you are already in a low signal area..problem. Global mode for our purpose of discussion = uses two types of radio, GSM and CDMA. The Verizon Network was built on the CDMA base and as of now you will have a better chance of "Hand - Shaking a 3G/4G signal in CDMA mode.
Thank you again for the reply. Changing from Global to LTE/CDMA didn't really make a difference. I've been playing around with signal strength and it definitely seems to be an issue with both phones in that putting them into a pocket most likely will cause the signal to drop to 3G from 4G.
I don't think I've ever seen it go back to 4G once it drops to 3G. Will it automatically go back to 4G when it detects a better signal? I don't think it has been doing that.
Mine will eventually. The easiest method I have found is to turn on airplane mode briefly, then turn it back off. It should come back on with 4G coverage.
Thanks BigLefty24. I have seen it go back to 4G but it is rare. You mention that you have a similar issue with your S5. Is yours always dropping to 3G regardless of signal strength? From my limited testing, my issue seems to be related to signal strength in that when the signal gets weak (1 bar), it will sometimes go down to 3G when in a pocket (I must have really bad luck in where my house is 
). I have yet to see it drop to 3G in an area where I have 3-4 bars.
Mine will switch regardless of where I'm at and/or signal strength. I took mine to the Samsung rep at Best Buy. He told me it should seldom drop to 3G in our area, and never to 1X. I proceeded to show him the screenshots of the phone in 1X along with the Google Map to verify location. He pretty much seemed dumbfounded. He asked for the phone in order to run the phone through his software to make sure the builds were correct. When I put the phone on the counter, it was showing 1X inside the Best Buy store. He said "you need a new phone".
He claimed he had never heard of this issue with the S5, but a quick Google search will quickly tell you it is definitely an issue. Good luck.
had hearing problems with my s5 dropped call, application problems can't turn phone off, had to take battery out. I can hear the person I called or they called me but they can't hear me. they feel that since they are replacing my 5th phone that I shouldn't get credit. I spoke to worthless supervisors. I didn't want to call them cause they make you feel like you are a liar, from corporate office linda, that handles better business complaints, a rep can promise a credit then not come through, they can lie and the supervisor condones the lie by saying it is a training opportunity. they don't honor a loyal customer and everything is documented. but refuse to do what is right. I spoke to ruben and ashton for device issues, but they said they hate to loose me as a customer jayde a phone rep kept me on hold for 30-40 mins without comining back to say the supervisor is busy or anything Donnie was another rep. the first thing out of there mouth you got a 25.00 credit on 12/4. but still having problems and refuse to get credit for issues today. I have insurance on my phone so they are not doing anything special. so they won't change me out of the phone I asked. do you trust a factory refurbished phone. what are my options?. do I trust Verizon lies
