How To Fix LG G3 Mobile Signal Dropping

The LG G3 is almost one year old now and this is the moment when most of the problems start to occur. No matter how good Android smartphones are, they have the tendency to run perfectly fine for a year or two and then start to give up.

Some of the most random problems start to show up like camera not focusing, keyboard lag, overheating issues and mobile SIM signal dropping. The latest is one of the most annoying among all because the signal that your phone receives from the SIM card is weak and it takes a long time to send and receive text messages.

Also, audio is very bad and it is a real pain to understand what the person that you are talking to in a call is saying because audio has a lot of noise or is too low.

If you are one of those people who are experiencing low mobile signal dropping on your LG G3, there are a few things that you can do which will hopefully fix the problem. Most of the time it is software-related which means that you can fix it. You can fix it even if it is hardware-related but only on a few specific cases.

The LG G3 is a great phone and it will serve great for a few years but as every smartphone, it will start showing its age, because 2 years is a long time for a smartphone. So here are a few solutions.

Solutions To Fix LG G3 Signal Dropping

Remove conflicting apps: The first thing you should do is to delete every app that might be conflicting with the system. These can be third-party apps which are used to make phone calls and send text messages like Viber, Skype and WhatsApp.

Factory reset: If you have uninstalled all the possible apps that might be causing the problem, then you have to make a factory reset. This will delete all installed apps on the phone, solving the problem.

Method 1

  1. Go the Menu of the phone.
  2. There, choose Settings.
  3. Find an option called “Backup & Reset”.
  4. Open it. Choose “Factory Data Reset”.
  5. Select “Reset Phone” and then “Erase Everything”.

Method 2

  1. Press the power buttons and hold it for 5 seconds to turn it off.
  2. Once the phone is completely off, press and hold the power and volume down buttons.
  3. When the LG G3 boot animation logo appears, release the power button.
  4. Press the power button one more time until the hard reset menu shows up.

Check SIM card: If a factory reset does not fix the problem, then it is hardware-related. Remove the back cover of your LG G3, then the battery and then take off the SIM card. Check the card for any possible damages or dirt. If it is dirty, make sure to wipe it with a soft cloth and then put it back in.


  1. this problem i am seeing isnt the cellphone but a firmware bug, if you change your network type from gsm cdma lte auto, to gsm cdma or wdma then the problem goes away, no signal problems at all, its only when you use the lte there are issues,

      • it has option
        Go to Mobile Networks —>> then Network Operators ===>> and then “Select Automatically”.

    • Thx 4 the hint! With my G3 I’m suffering from bad receiption by hardware plus SW bug. And both potentize. Today it was totally crazy again. I frequently needed to switch to airplane mode and back to make the phone find the carrier. Changing to G2/G3 seems to improve the situation clearly (but of course it’s way to early for a final judgement). I rather sacrifice 30% of data rate than being out w/o receiption all time…
