Hello Astoyan,
Welcome to the community!
Firstly, it's not uncommon for different phone models to have differences in cellular reception. For example, a professor at Denmark's Aalborg University tested the performance of various mobile phone antennae (see here). I'm not sure how much we can extrapolate from his data because Fido/Rogers uses mostly different bands/frequencies and the study is now a few years old. However, it does illustrate the large differences between phone models. The reception of the Galaxy S7 could be better than the LG G4.

While it does seem that your location might have less than adequate signal for the G4 to function well, it is quite normal for phones to switch from LTE to the '3G' or 2G networks for calls. With the exception of voLTE, voice calls are handled using the '3G' or 2G networks. Most phones will standby with the best available data connection (ie LTE, if available). When making or receiving a call, a phone without voLTE has to switch networks.
You should note that the best available data connection may not necessarily be the fastest. It depends, in part, on the band or frequency to which the phone is connected. The different frequencies have varying characteristics. The higher frequencies do not travel as far, nor penetrate as well as lower frequencies (see graphic here). In addition, cellular reception is dependent on your location relative to the cellular towers and the bands/frequencies used at those towers -- not all bands/frequencies are used at all cellular towers. You can get an idea of your surrounding cellular towers here.
You might consider trying to disable LTE to see whether the phone can maintain a more stable '3G' or 2G connection for calls. You could also determine the signal strength using those networks. If the signal strength is similar to the level you posted previously, it's possible the weak signal is affecting your calls.
Hope this helps 
Cheers
Hello again,

Had you previously been able to use that phone properly at that location? As previously mentioned, different phone models to have differences in cellular reception. Some phones' antennae are better (stronger, better placement, etc) than other phones at receiving weaker signals. That study illustrated some differences between phone models. At your location, the signal strength may be strong enough for the Galaxy S7 to work properly, however, might not be strong enough for the G4 to function adequately. There might not be anything wrong with the phone, but reflects differences in design, manufacture, components etc. How does the phone work at different locations?
What signal strength does the S7 show? Most sources would consider less than -100dbm weak enough to cause service issues and -120dbm to be a relative dead zone. Your phone shows a level closer to the latter end. Assuming your phone showed -116dbm when connected to LTE at 700MHz, it's possible the signal strength would have been worse when connecting to the '3G' or 2G network for calls. The different frequencies have varying characteristics. The higher frequencies do not travel as far, nor penetrate as well as lower frequencies (see graphic here). The lowest frequency for the '3G' or 2G networks is 850MHz which would not travel as far nor penetrate as well as 700MHz. The S7 might be able to perform better under those conditions.
If your phone had previously performed properly at that location, it's possible replacing the motherboard may help. On the other hand, if you have always had this issue with that phone, I'm not sure if replacing the motherboard would solve your problem.
One possible solution would be to get a signal booster. I understand it would be an added expense.
I also understand your hesitation in getting another phone. If you do not wish to get a Galaxy S7 (seems to work well at your location), I would suggest trying to research which phones have the best cellular reception. If you do get a new phone, you do have the 15 day guarantee to make sure the phone works as it should.
Hope this helps

Hey @astoyan
Having technical issues are definitely not an ideal situation😟
In order to better understand the situation, are you able to give us more details as suggested above:
- Have you tried your sim card in your wife's phone?
- Is this happening everywhere?
- What happens when you test your SIM card in another phone?
- Does reseting your device to factory settings help?
To take a closer look at the details, you can contact us here or we can send you a PM.
Let us know what suits you best!
Hey ayrdale!
Could you give us more details?
Let us know if:
- This is happening everywhere,
- What happens when you test your SIM card in another phone,
- If reseting your device to factory settings helps.
Thanks!
Thanks for confirming @Award88!
Don't hesitate to reach out if there's anything else we could help with.

Hey Jarv!
Welcome to the Community!
Are you experiencing this everywhere or is this something that only happens in certain locations?
Does the same thing happen when you put your SIM card in another phone?
Let us know!
