Lg g4 loses cellular signal completely randomly

Hi, my lg g4 loses its cellular signal randomly for a second and then I get a full 4 or 5 bars afterward. This is annoying because I constantly drop calls. I changed my preferred network to GSM/HSPA/LTE auto to simply GSM/HSPA auto and that hasn't helped. Although my signal is much stronger. However, I still lose the signal every now and then. I have no clue what I should do?

Hey @Award88 and thanks for reaching out.

 

This issue happens indoor and outdoor as well? 

 

And when you restart your phone, do you get a different result?

Mostly outdoors, but occasionally happens indoors as well. When I am on WiFi calling there is no issue.

@Award88 

 

Thanks for the reply Smiley

Another question for you. Did you get a chance to try your sim card in a different Fido phone to see if you get the same issue?

Hey,

 

No I have not, Although my girlfriend has a g3 and she is with fido as well. She doesn't seem to have any problems. I forgot to mention that, the phone seems to "skip" or "freeze" when the cellualr signal is weak. I think it happens when it changes network type. I'm only guessing here though, because I changed my prefered network from gsm/hspa/lte auto to only gsm and that seems to fix the problem. 

 

I thought is was a sim card problem as well so, i got it changed last week. But it didn't fix the problem then.

Yes as long as I stay off my LTE network.

Hi,

 

Do you mind me asking what the fix was?

 

I have been having the same issue with my G4 for a couple weeks; had the sim changed and still the same thing.

 

Moving the sim to a 4G/GSM only Samsung Rugby flip phone & it only provded that it was not a sim issue.

 

Any info would be great!

 

Thanks!

Hi @erdemkiyak & welcome to the Community!

 

Have you had the chance to test a different SIM card in your phone to see if the issue persists? Let me know. Smiley

Re: Lg g4 loses cellular signal completely randomly

Hi,

I'm having the exact same issue since I switched to Fido. My LG G4 starts randomly losing network connection for about 2 seconds before going back up with all full bars of reception. When stucked in this loop, these 2 to 3 seconds network drops happen every couple of minutes, making it impossible to have a phone call and very frustrating to use data. If I reboot my device, it looks fine for a moment but this issue always come back sooner or later. I also realized that if I try to do a speed test using the Fido app, it will automatically result in a network drop and I'm automatically back in the network-drop-every-5-minutes loop. I went to a Fido store and my SIM card has been changed and my APN settings were double checked. Still happening. My unlocked G4 was purchased at Koodo and I got confirmation that Fido is using the same LTE bands as Koodo so the issue should not be coming from here also. I'm currently out of ideas on why this is happening. All previous answer don't seem to show that a final fix has been found or am I mistaken?

Hi @boriscolin!

 

Would you happen to have another phone in which you can test your SIM card to see if it's the network the issue?

Re: Lg g4 loses cellular signal completely randomly

Hello, I have exactly the same issue. LG changed 4 times my motherboard and the issue still the same. But for me it append only when I'm connected with my car bluetooth. I clearly see the network dropoff then the cross for no network and only few seconds later a full signal.

Do you have a solution fir this? Thanks
