Here’s a message that just came in Mailbag, “I noticed that after downloading the 4.4 update, I started experiencing Galaxy S3 mobile data problems. I mean, it suddenly turns off randomly. This is very irritating because whenever I am in the middle of browsing the Internet, my browser suddenly stops loading and I get this message about my mobile data being off. How can I fix this?”
Possible Causes of the Galaxy S3 Mobile Data Problems
Upon doing my research, I encountered the same type of issue in the product forums of Google. However, the problems seem to affect a number of Nexus 4 devices. Several reports online have also confirmed that many people who got the 4.4 update have experienced bugs after installing the new Android version. Again, most complaints came from Nexus 4 users but there were a handful of people with other types of Android devices who sent us complaints with similar nature too via Mailbag.
The bugs coming out vary in nature. Some of them result to the phone getting lags, unresponsive keys, apps getting haywire, losing network connection and losing mobile data randomly. But one thing is common from people experiencing them, that the problems only started after the installation of the 4.4 version.
Based on the various online forums and other complaints that we have been receiving, it is likely that the Galaxy S3 mobile data problem in 4.4 is caused by the update itself.
How to Fix the Galaxy S3 Mobile Data Problems After Updating to 4.4
Restarting or doing a Soft Reset to your device might solve the problem. Try also removing your battery while your unit is on and then put it back again for a restart. This solution may only be temporary though.
A Factory Reset is also advisable in order to ensure a clean installation of the new OS update. Usually, bugs that come after an update are removed through this procedure. Just make sure to back up your data prior to this.
If a Factory Reset fails to do the trick, you can report the problem to your carrier so they can coordinate with Samsung for a fix. Once a fix is available via OTA, install it. However, if you cannot wait for it, you can always flash your phone to an earlier version. This process is risky though so make sure that you do your research well before going about it or seek help from a person with technical knowledge about the matter.
