LG G5 not connecting to data network unless I reboot

[erinb90]

My G5 is about 3 months old. Last week it installed an LG software update. Since then, whenever my signal gets weak or lost (such as in the subway or a basement), it does not reconnect back to LTE once I have a strong signal again. Sometimes I will get a phone signal but not data, other times I will not even get a phone signal at all. Once I restart the phone, everything works fine again.

Toggling mobile data on and off does not work. Turning airplane mode on and off actually makes it worse (I lose signal entirely). Wifi connection is fine. 

I have tried resetting the network settings, no change. I then did a factory reset, no change.

This happens several times a day so it is very annoying having to always reboot my phone.

Does anyone have any advice, or will I need to replace my phone under warranty?

Is the same thing happening on LTE and on 3G only? Have you tried another SIM card in your phone or your SIM card in another phone? 

What other tests have you tried so far, Nico78? 

Let us know!

my phone has had several manufacture defects I am on the 3rd ome LG has sent me. 

Now my data work work. It isbat one bar constantly and never on LTE despite my location is the same place I have been for 3 year no problem. 

Factory reset, reboot, network reset, apn setting reset, new sim card, 11 technician phone calls..

nothing has helped, the techs at fido told me to google it or get a rabbit eat antenna for my phone.

So frustrated, can not do my job. May have to cancel plan and switch to new provider if they cant fix my problem

Hey @casey3

I would like to take a look at what was done so far about your situation.

I'm sending you a PM now to get this looked into. Talk to you soon.

Thank you, they tech team seems to think I have exhausted my options.. I am very frusterated as I had perfect Lte service before, and my problem Is I can not uploaf videos to my social media as my data connection is so poor, also it will not upload with wifi as my connection is poor. But the last couple years it has been perfect, last month Everyday I was uploading videos in a split secomd and now I wait 5 days and its still in the que and will not load. I can scroll social media I can google websites and get to the browser but I can not upload or download.

I am having same issue with my lg g5.

The APN configured correctly

Network reset and factory reset didn't help.

It's very annoying. I keep rebooting my device abou 20 times a day.

Hey @alexlip80,

Welcome to our Community!

I get that having to reboot your device that often must not be pleasant

I've a few questions for you to get more info and assist you better:

1. Does this happen only indoors or outdoors as well?

2. What OS are you running?

2. Would it be possible to test your SIM card in a different device? This would allow us to know if the situation is device specific.

Thanks in advance!

Same problem here, started a few weeks ago and I think it was just after an LG app updated. Indoor/outdoor doesn't matter, signal strength doesn't matter, it happens randomly over time even when I stay in the same place, about once per hour. Data is the problem, calls work fine. Like the others, only solution is to reboot several times per day.

OS is Android 7.0
I don't have another device to test SIM

[FidoNick]

This is definitely odd @TheFirstDeity!

Do you have VoLTE active in your settings? If so, have you tested it with that option disabled?

This does seem to maybe be software related. Is a software restore something you'd be able to try?

Let us know!

Hey @TheFirstDeity!

We haven't heard back from you. Any updates on the situation?

Hi

I am also experiencing the same problem as these users

• Data randomly drops when in LTE, in urban areas like Toronto, Mississauga, Hamilton
• Done 2 factory resets and still not fixed
• Got a new SIM from Fido still didnr fix the issue
• Talked to a mobile repair shop and they claim I got a dud, that LG motherboard fail after a year. To repair the phone would cost me $200

Only fix I found is to use 4G only, which is not what I paid for in the 2 year contract.  

I got my phone brand new April 2017, and to buy out the contract will cost me $230.

Is there any solution that won't cost me as much and for Fido to honour my 2 year contract which is access to LTE data speed?

Hey Nngo2k

So sorry to learn you're having trouble with your phone. Have you checked with LG to see if this is an issue they are aware of?

If it is a known issue they may sometimes offer a replacement or repair option outside of the warranty. 

Keep us posted!

Disabling VoLTE didn't work. I don't want to do a software restore yet because it looks like it's been ineffective for everyone else on this thread.

[FidoRachel]

Let's try something @TheFirstDeity, this will erase saved Wi-Fi passwords.

From your settings, find the Backup & Reset option, and select Reset network settings

Let us know if it helps!

Hey @TheFirstDeity

Did it end up working on your side?

I had this issue, I disabled the wifi calling and it fixed the problem.
