The mobile phone has evolved through the years from simply making calls to performing other things such as going online. Despite all of the features a smartphone may have the consumer will mostly still use it to make calls. Take for instance the #Samsung #GalaxyS4, this phone which was once the flagship model of the South Korean giant comes with advanced hardware that lets you go online through Wi-Fi or mobile data, check your location using GPS, and connect to other devices using Bluetooth.

S4 Unable to Make Or Receive Phone Calls

Problem: My husband did a system update-the software was updated to 1545VRUGOF1. After that, he has been unable to receive or make phone calls. The phone goes straight to voicemail. I tried seeing if it was an app issue by putting the phone in safe mode and having someone call me. It didn’t work. I also took out the battery and replaced the SIM card, which didn’t make any difference. Any ideas about how to get my phone working properly? Thanks in advance.

Solution: Since this issue occurred right after a software upgrade then there’s a possibility that it may be caused by old software data that has not been completely removed from your phone. This old data conflicts with the new software version and is now affecting the call capability of your phone. The best way to deal with this is to back up your phone data then do a factory reset. Once the factory reset has completed test if your phone can make or receive calls.

If the issue persists then the problem may be with the update itself. Try checking if your carrier has released any additional updates that may fix this issue.

S4 Stuck In Dialing Mode

Problem: The phone keeps getting stuck in dialing mode. I can’t hear the person calling and they can’t hear me. I have done a full factory reset and booted to safe mode but still not working. Anything else I can do to fix this.

Solution: If the factory reset fails to resolve the issue then there’s a possibility that the phone software may be corrupt. You should consider reflashing your phone firmware and see if this resolves the issue. Since reflashing the phone firmware is not supported by Samsung you will have to do it manually. You will need software called Odin installed in your computer and the exact firmware file of your phone. Instructions on how to perform this procedure can be found at most of the popular Android forums online.

If reflashing the phone software fails to resolve the issue then this may already be caused by a faulty hardware. If this is the case then you should bring your phone to an authorized service center and have it checked.

S4 Automatically Makes A Call

Problem: Automatically makes calls to the last person that called me.   Also, after texting, it calls the person

Solution: You may have activated the lift to dial feature of your phone. To turn it off go Settings – my device – motions and gestures – motions – direct call then turn it off.

S4 Call Freezes When Wi-Fi Activated

Problem: Hello, my name is David and I read an old article of yours about problems with the Galaxy S4. I wanted to know if you could help me with my problem. When I am connected to Wi-Fi and a call comes in, I swipe to answer and the phone freezes and I can’t answer. The phone continues to ring until it goes to voicemail and by that point the phone unfreezes and works normally. When disconnected from Wi-Fi, I can receive a call and swipe to answer and it works perfectly. I don’t understand why it does that. One of my other family members also has the same phone and theirs works just fine. I removed my Lifeproof case as well to see if that would be a problem, but I still have that problem. I would appreciate an answer from you. You do a great job explaining things on the site. Thank you for your time.

Solution: This may be an issue concerning your phone software and is probably caused by some form of corrupt data. I suggest you back up your phone data then do a factory reset. If the issue still persists after this then this may already be a hardware related problem. I suggest you bring your phone to an authorized service center and have it checked.

S4 No Sound During Calls

Problem: My S4 has the same problem described in your posting dated Aug 9, 2015: How To Fix A Samsung Galaxy S4 That Can’t Make Calls & Other Related Issues. The phone has been working fine until one day I cannot hear any tone when dialing.. cannot hear any ringing tone from the other side either.  But the other party can hear the ring but cannot reply b/c its like muted.  And this is using TMobile network.  When I switched to WiFi calling, it worked just fine and like normal. I read some QA threads on TMobile website, the problem may be related to the Motions and Air Gestures functions and/or Sensors. I disabled all those functions, did a hard reset as described above, but the problem remained the same. Another strange thing I also noticed is that after a hard reset, the green android appears, but is has the word “”error”” in red underneath.

Solution: Have you tried starting your phone in Safe Mode then check if the issue still occurs? If it doesn’t then it may be caused by a third party app installed in your phone. Find out what app this is and uninstall it. If the problem still occurs try taking out your phone battery then press and hold the power button for at least a minute. This completely discharges your phone of any remnant charge and clears out its RAM. Reinsert the battery then try to check if the problem still occurs.

As for the issue with the green Android with error written underneath this may an indication that there is a software problem. Is your phone still running on its stock software or is it running on a custom software? If your phone is on stock software then try checking if there are any new software updates available as this will usually come with fixes that will resolve this issue.

S4 Can’t Make Calls Due to Decreased Signal Strength

Problem: Since updating to lollipop my signal strength has been less. My biggest problem is that I work in a steel building. I’ve always been able to text and receive an occasional call. Now I have no bars and an x. When I go out for lunch or home I have to restart my phone otherwise the no signal x remains and I cannot make any calls or texts even outdoors.

Solution: Since this problem occurred right after your phone got updated to Lollipop I suggest you do a factory reset.  This is the most recommended troubleshooting step when issues arise after a software update since it clears your phone of any old software data that may not have been completely removed. Just make sure to back up your phone data before performing this procedure.

S4 Can’t Make Calls Due To No Service

Problem: My phone just recently stopped getting service? everything works, but I can’t accept calls or txts? I work outside for 8hrs a day and thought it could be fried? im not sure. All my bills are up to date, I’m just not receiving any service. I have tried taking out the battery and everything. Any suggestions?

Solution: Try checking with your carrier first if there are any network related issues in your area. If the network is working fine then try starting your phone in Safe Mode then check if your phone gets a signal. If there is a signal then the problem is most likely caused by an app installed in your phone. Find out what app this is and uninstall it.

If however the problem still occurs even in Safe Mode then you will need to do a factory reset to isolate any software related problems that is causing the issue.

If the factory reset fails to resolve the problem then I suggest you bring your phone to an authorized service center for further checking as this may already be a hardware related problem.
