Problem #1: Galaxy S4 with incorrect IMEI won’t connect to Wi-Fi

Issues: Wifi & Sound.

I am the frustrated owner of a Samsung Galaxy S4 (Kit Kat 4.4.2), which I regretfully bought online. When I got it in the mail, I noticed that out of the 3 different places for me to find the same IMEI number, 1 of them was actually different. When I ran a check on the number that had a match the feedback was that, that IMEI number actually belonged to a refurbished Samsung Galaxy Note 2 rather than what I ordered/paid for.

Then after trying out the phone I realized I wasn’t able to connect to any WI-FI connection no matter how I tried. The icon would change from colorless to light green (as it does when it’s loading/trying to connect) but it wouldn’t get any further than that.

I ended up worried that I’d bought a dodgy Galaxy Note 2 “posing” as the Galaxy S4 that I wanted and that I’d chosen a dodgy seller who was just trying to rip people off.

So I sent it back along with an explanation and some evidence of the issues. Within 4 weeks the phone was sent back to me, with the same mismatching IMEI numbers, a charger that started sparking and melting on its 2nd use, still no ability to connect to WIFI, I’ve just had to change to my 3rd battery replacement as the phone caused the others to bubble and swell, my service/reception  spontaneously disappears and then reappears when it feels like it and in the last 3 weeks the phone has no sound output through the left speaker of any device plugged into it.

I’m sorry if I rambled a lot! I just want to know how to get WIFI back (if I can). How to get the sound output back and if I’m the only one experiencing these frustrating bulls#*t problems? Thank you for your time! — Chloe

Solution: Hi Chloe. All IMEI numbers on your device (accessed via the dialer by pressing *#06# and Settings) should match. Otherwise, you can be sure that the phone is either a knock-off or stolen. In your case, it appears that it’s not only either a fake or stolen, but it’s defective as well. The Wi-Fi failure to connect issue may be due bad hardware which will be impossible to fix on your end (unless you have advanced electronics knowledge on how to diagnose Galaxy S4 parts and replace defective ones). A good thing to see if there’s a hardware issue is to perform a factory reset. This will eliminate a possible firmware-related cause. Troubleshooting an Android device is often simple and if software’s okay, then it must only be the hardware that’s messing up. For easy reference, please follow these steps on how to perform a factory reset:

  • Turn the phone off completely. (Remove the battery and place it back in)
  • Press and hold the Volume Up, Home and Power buttons.
  • Release the Power button when the phone vibrates but continue holding on to the Volume Up and Home buttons.
  • When the Android System Recovery screen appears, release both the Home and Volume Up buttons.
  • Using the Volume Down key, highlight ‘wipe data / factory reset.’
  • Press the Power button to select it.
  • Using the Volume Down button again, highlight ‘delete all user data.’
  • Press the Power key to select it.
  • Once the reset is complete, choose ‘Reboot system now.’
  • Press the Power button to restart the phone.

Problem #2: Galaxy S4 freezes and performs slow

My phone screen is freezing up in the middle of whatever I’m doing whether it’s the Internet, an app etc. If I turn it off and back on I have up to 30 or 60 seconds that I can do something on my phone before it freezes again and the touch screen doesn’t work at all. It was having some issues of being slow or occasionally freezing and I would restart and it would be fine. Then it was getting hot so I thought maybe I had a problem with my battery. I bought one on Amazon that said it was a Samsung battery. I put that battery in and that’s the first time that my phone completely froze. I removed it and put my old one in and it would work a minute or 2 then freeze.

I read about putting it in safe mode which I did and it does work fine in safe mode. I don’t know a lot about phones and I don’t really know how to just do a reset without losing all my photos and stuff. I do have Dropbox that backed up some of my pictures but it’s full so I think I would lose all my photos if I just factory reset, so I have not tried that. I have tried taking it back out of safe mode a few times and it still freezes right back up within about a minute.

One other thing I did that could have messed it up, I was trying to make sure nothing was wrong inside and I pushed in the sim card  and the sd card and they clicked partially out as if I were going to remove them. I didn’t actually remove it, I clicked it right back in. Later though I read that’s bad to remove the SD card. I do have some of my apps on the SD card because I don’t have enough memory on my phone. I’m the only owner of this phone. I got it new from the store about 2 and a half years ago. This is my first issue with the phone. I would be so grateful if you can give me any advice at all. Thanks so very much! — Chelsea

Solution: Hi Chelsea. That the problems you mention here are not happening when your device is on safe mode is a clear indicator that one of your third party apps is to blame. If you don’t want to do a factory reset at this time to avoid creating backups of your files (although we highly recommend that you do this as a precaution), try to remove files individually until the issues are gone. If you have many installed apps, the process may take longer than usual but this is definitely an effective method. There’s no faster way to pinpoint which of your apps is problematic.

If you have a computer, try to copy your files to it as backup then perform a factory reset. Keep in mind that factory reset will not be the solution for the problem itself. You still need to install each app then observe the phone before you can be sure that the issue is resolved. If you re-install the same set of apps after a factory reset, you are simply re-introducing the problem.

Problem #3: Galaxy S4 touchscreen issue

Hi, I’m writing from Italy. i look at your guide on http://thedroidguy.com/2015/04/samsung-galaxy-s4-problems-glitches-questions-errors-and-solutions-part-72-105504. I would like to submit you a question about this phone.

I bought it in Saudi Arabia in Feb 2014. It worked fine till July 2015, when it fell down (50 cm) and the touch stop working. It was not an hardware problem. I was in Dubai last August and at the shop they just fix the problem with a “Software update”. Everything was okay until last month when suddenly the problem appeared again.

I performed an hard reset but didn’t resolve the problem. I loaded the new 5.01 Android Lollipop and it didn’t solve the problem.

For sure it is not an hardware problem because if the phone is on stand by, LCD off, and i press the power button, i can unlock the screen using a finger on it, but at the home page i cannot do anything (just buttons are working).

If instead i already open an app, if i put the phone in standby by pressing power button and wake again by re pressing it, i can do 1 operation (1 click) and after the touch stops working.

So i was able to go inside an app, turn off, turn on, click on menu, turn off, turn on, click on a field, turn off, turn on, and so on.

Do you know if there is some upgrade or software recovering in can use to fix this problem? At the Dubai shop they didn’t want to tell me what they did.

Thank you for your support and your time. — Nicola

Solution: Hi Nicola. Try to boot the phone in safe mode and observe the phone for 24 hours. In this mode, no third party apps are permitted to run. If any one of them is causing the issue, the issue should fail to occur. Here’s how it’s done:

  • Press and hold the Power button.
  • Once the Samsung Galaxy S4 logo appears on the screen (assuming the phone responds to Power key press), release the Power button.
  • As soon as you release the Power button, press and hold the Volume Down key.
  • Continue holding the Volume Down key until the phone has completed the reboot process.
  • If you can read ‘Safe Mode‘ at the bottom left corner of the screen, release the Volume Down key. Otherwise, repeat the process until you can boot the phone to Safe Mode.

If the problem remains even when on safe mode, make sure to create a backup of your files and proceed to perform a factory reset (steps provided above).

Problem #4: Galaxy S4 intermittent cellular connection

Hello, I have an odd problem regarding my Samsung Galaxy S4. I have intermittent service. It used to be alright, but now it comes and goes. I tried a factory reset but it didn’t solve it. I will have like 3 or 4 bars of service and then it will drop service, however it will still show the bars. Where it usually says T-Mobile, it just says searching. I took it apart and looked at the Antenna Contacts and they seem to be fine, but I’m not 100% sure. I can send and receive texts when it works, and can call when it works, but once it says searching there is no network. I have this issue periodically when my family has 3 or 4 bars throughout the house so the issue is my phone. I was wondering if there is a fix to this or am I going to have to replace the phone. Thanks for listening to my issue. — Brett

Solution: Hi Brett. There is no way to know for certain what the problem might be. We suggest that you do the basic software troubleshooting like wiping the cache partition, booting in safe mode, or doing a factory reset. These are solutions meant to fix software issues. If they won’t work for you, then you can be certain that there’s another trigger from the hardware side. Our blog does not provide hardware troubleshooting and diagnostics so if you want to look for guides or tips on what to do, please use Google to look for them.
