Problem #1: Samsung Galaxy S5 unable to search the internet using Chrome and stock internet browser

Firstly, Thanks. This is a great service.

This problems seems to pertain mostly to my data usage and not to wi-fi, although I haven’t tested it on wi-fi in three days.

Now. My internet doesn’t work. By that I mean I can’t search. I have the Internet app that comes standard with the phone — the Chrome app and the Google app. None of this those can access the internet. HOWEVER, One in three or four resets I can do a single search before it stops working.

BUT. I get e-mail (via Gmail). I can use the maps app and even change it to satellite images from the regular map ones. I can connect to my mobile data and create a local network and several people can join it and browse via their phones and/or laptops perfectly at high download speeds. My apps update naturally.


  • cleared caches
  • soft reset
  • rolled back my Chrome and Google apps
  • checked if there were any app settings that removed Chrome/Google etc from internet access.
  • scoured the internet (which I’m currently using off my laptop but through my phone). 

Most boards that I’ve read about “a similar” issue are at least a year old, fixed and or not perfectly related.

Hope you can help. Having a fun time trying to figure this out. Best. — Chris

Solution: Hi Chris. You have an interesting case here. This issue seldom happen (or probably reported) so it’s understandable that there are not much literature floating around the web to help users like you. The way we see it is that the situation may be isolated to your device due to some firmware or third party application blocking your internet browsers to connect. Unless your carrier is blocking Chrome and the stock internet browser apps from connecting to the internet (which is very unlikely), there are no other reasons that might have caused this problem.

We think that this problem can be fixed by doing the standard solutions for software or firmware issues. The first one is by booting the phone in safe mode. While manually checking settings of other apps that may prevent Chrome and stock internet to connect has been done, we still recommend that you restart the phone in safe mode to make sure that you are not missing anything. Safe mode prevents all third party apps from running so it’s a more efficient step to do first. If you haven’t done this before, these are the steps to do it:

  • Turn the device off.
  • Press and hold the Power key.
  • When ‘Samsung Galaxy S5′ appears on the screen, release the Power key.
  • Immediately after releasing the Power key, press and hold the Volume down key.
  • Continue to hold the Volume down key until the device finishes restarting.
  • Safe mode will display in the bottom left corner of the screen.
  • Release the Volume down key when you see Safe Mode.

If nothing productive comes out after you boot your S5 in safe mode (some apps may simply ignore safe mode mind you), consider isolating the issue further by making sure that it’s not the current firmware causing the issue. To do that, you must perform a master reset. Here’s how:

  • Power down the Galaxy S5.
  • Press and hold the Volume up button, the Home button, and the Power button together until you see the Android on screen.
  • Use Volume Down to highlight the wipe data/factory reset option and press the Power button to select it.
  • Use Volume Down again to highlight Yes – delete all user data and press Power to select it.
  • Use the Power button to select Reboot system now.
  • When the S5 restarts it should be completely wiped and ready to set up again.

After doing a factory reset, make sure not to re-install your apps. Try to search using Chrome and the stock internet browser to see the difference.

If the issue remains after this procedure, you may want to try using custom ROMs or simply skip Chrome and stock internet browsers altogether.

Problem #2: Galaxy S5 losing mobile data connection

Since this morning on 10/5/15 i have had issues with my 4G network. The device will only allow me to connect to the wifi and i haven’t been able to make calls or messages. in other words I’m paying for nothing. In some cases it pops up and 3 seconds later it disappears. I have tried a soft reset many times but it won’t work. I have also removed the SIM card completely but no luck. how can i fix this problem? This has been eating my battery by a lot. — Ruben

Solution: Hi Ruben. The best party that can help you fix this type of problem is your carrier. There’s a 50-50 chance that the issue may be network in nature so calling your carrier should have been your first option.

Another good thing to do to know if you’re area or account by some service disruption is by inserting your SIM card in a known working device. If mobile data works similarly on another device, the issue is most likely coming from your network.

It’s also worth noting that you need to check if there are any account- or billing-related problems that might be preventing mobile data to work. These can only be addressed by your carrier making this step all the more important.

Assuming that there’s no network  problems in your area, start your phone troubleshooting by toggling between the available mobile network modes. You can do that by going under Settings>Network connections>More networks>Mobile networks>Network mode. This is a simple workaround that sometimes clear things up so it’s worth trying.

You can also try to toggle Airplane mode on and off a few times to see any difference.

If these remedies won’t work, restart the phone in safe mode (steps provided above).

Sometimes, clearing the system cache works may also help fix connectivity issues so that’s worth giving a try as well. Here’s how:

  • Turn the phone off.
  • Press and hold the following buttons together: Power, Volume Up and Home.
  • Release the buttons once the Android system recovery menu appears.
  • Use the Volume buttons to navigate to Wipe Cache Partition option.
  • Press the Power button to confirm selection.
  • Select Reboot System Now option after deleting the cache. Wait for the phone to reboot.

Performing a factory reset should be your final step. Make sure to create a backup of your personal data (photos, videos, messages, contacts) before proceeding.

Problem #3: Galaxy S5 with Net10 SIM unable has no mobile data and voicemail services

Unlocked phone previously from Verizon. Switched to Net10. Cannot get on mobile data or use voicemail. Please help. — Lindsey

Solution: Hi Lindsey. Just like what we advised Ruben above, your best to resolve this issue is by calling your current service provider to know if there are specific account-, billing-, or network-related stuff that are missing somewhere. To successfully use mobile data, a smartphone must have all the right network information configured. Only your carrier can help you with that.

If your phone works fine when you were with Verizon before, then there shouldn’t be any phone-related problems that should prevent you from using the similar services from Net10. The most likely reason for all the trouble must have something to do with your network.

Problem #4: Galaxy S5 keeps getting server error message

HELP ME PLEASE!!!WHY DO I KEEP GETTING A NOTIFICATION A ZILLION TIMES A DAY TELLING ME ABOUT A SERVER ERROR?? What the hell is a server error and more importantly how do I stop having one in the first place. .Mucho respecto amigos.

Regards from a not so smart dude in charge of a smart ass phone. — Angus

Solution: Hi Angus. We need more information from you to be of effective help. Can you tell us what are the circumstances of the case? We need specific information like what apps you are trying to use when this error pops out, things you were doing leading to the problem (did you update something, downloaded and installed an app, etc), to mention a few.

In general, server error messages can mean anything. For instance, a server error message may show if you have slow or intermittent connection when you are using an internet browser app.

Problem #5: Galaxy S5 won’t store Wi-Fi passwords

Hi. I have a problem with WiFi. I can’t remember exactly which Update I have installed but for new networks, my S5 device cannot store WiFi passwords. I wiped Dalvik cache, I made a full reset (factory) but it does not help.

Some of the older WiFi connections do not have this problem and even after factory reset, those connections are working without entering the password again. This is somewhat strange.

I thank you for any help. — Markus

Solution: Hi Markus. That’s a definitely strange problem. If a factory reset did not make any difference, we don’t know what will either. This must be a rare issue or even an isolated case to your device.

Consider doing another round of factory reset but do not re-install third party apps right away. Factory reset is not always effective especially if you simply re-install the same set of apps afterwards (assuming that one of your third party apps is the culprit).

Problem #6: Solution for Galaxy S5 having difficulty connecting to 4G network


So thankful for guys like you that post stuff like this: How to Fix Samsung Galaxy S5 Network, Mobile Data & Wi-Fi Problems for free!

So I just upgraded to a an S5 from a S4 and could not access the data. Farted around a couple of sites and trying to look for solutions until this came up. SO … the problem was that there was a PASSWORD and a SERVER that was set (4 characters and 1 character respectively). Once I deleted them, my 4G network instantly came on!  YOU ARE SOOOOO THE MAN!

Problem #7: Galaxy S5 no longer connecting to Wi-Fi

Hi. I’m having a problem with my Samsung Galaxy S5’s wifi: it just can’t connect. It still says “there are available wifi connections” and asks if I want to connect, but every time I try to connect it doesn’t even get to the “obtaining IP address” part. My mobile data still works but I don’t want to keep using it.. I’ve tried a soft reset, forgetting and re-entering the (correct) wifi password and I’ve been on youtube and other threads and it seems like the only option left is to perform a factory reset, but I really don’t want to because I’m scared I’ll lose all my stuff… (Kies does not work at all (Mac user): it’s the reason my android version is still so low). Is there any possible way other than a factory reset??

Thank you. — Abbie

Solution: Hi Abbie. The only remaining potential solutions before actually doing a factory reset are the following:

  • booting in safe mode (and uninstalling possible problem apps)
  • deleting the system cache or cache partition.

Steps are provided above on how to do these procedures. If they won’t make any difference, proceed to factory reset.

One Reply to “Galaxy S5 losing mobile data connection, more connection problems”

  1. Guys thanks for the tips. My S5 was losing internet connection over the mobile network. Switching network mode fixes it. Is this more likely to be a network provider based issue or a Samsung issue as they are blaming each other at the moment. Martin
