Network connection cuts off randomly - can't talk, nor text


Have been with Koodo for 1.5-years.  Using LG G3 bought from bestbuy (it is a Koodo phone).
All was working fine until a number of weeks ago.

Suddenly and randomly,  network connection cuts off, so I can't talk, nor text.  Nothing coming in, nothing can go out.   I was able to access internet.

The display (at top of screen) normally shows 2, 3, 4 "bars" for cellular reception.  But now it showed none (all 5 bars were 'blank') and there was an "X" on top of it.   It must mean that reception is off.   But I did not touch anything, so it just went off.  I have lock-screen enabled with a code, so it can't be modified by mistake.   I am in the city, where the is always reception, so it is not an issue of being in a remote location.

This problem has happened a few times over the past little while (1 month or more).

The big issue is that I do not know if my phone reception went off 15-min ago, 2-hours ago or 4hrs ago.  And during that time, I can't be reached via voice/text.

I tried playing with settings, to no avail.  Only way to "fix" is to restart phone.  This is not normal.

Any ideas?

So if you restart your phone everything is fixed? This most likely means it is time for an upgrade or a repair to your phone.

I had the same issues with my G3. Only thing that fixed it was a factory reset of the device. If you don't know how, check YouTube for a tutorial. Edit. Here's a link
OK.   A bit drastic.  Phone is just over a year old, between 1 and 1.5yrs old.

@Chadwick: How old was your phone when you had these problems?   What did you try before doing a factory reset?

I had my phone for less than 8 months at the time I had to do the reset due to network issues. You could also try checking for a software update or consider any poor signal issues around you that could be the cause. If you decide to reset just do a back up of the device(contacts, pictures stuff like that) sometimes it's nice to reset as the phone has a chance to run like normal for a little without all the heavy apps we use.

Forgot about a factory reset, this is deffinitely worth a try but a repair or replacement isnt drastic esepcially with phones these days. A friend of mine has his LG G3 for exactly a year and a half and it completely died. The screen would turn off every 30 seconds and it was ruled down to a motherboard problem that multiple people have experienced with the phone and would cost more to fix then it was worth.

It is drastic without exhausting every other avenue first. Especially with the price of phones these days.

Also the possibility of a gibbled SIM card. Can you try another SIM in your phone? Either borrow one from a friend, or stop by your friendly Koodo Kiosk and they have a test SIM.

I would try powering down, removing the SIM card and powering back up (it should flush whatever SIM data was there and will give you an error).

Power down, re-insert the SIM card, restart. Go to [b]settings > [b]network > [b]more > [b]network operators and manually force Koodo to start.

Will cost you a few minutes' time and reset your comm link without having to do the factory reset.

Since you're out of warranty, check out on Youtube

Lol my brother did the oven solution. Worked for a little while.
Thanks for the various tips.  To respond:

-I take very good care of my phones.  Changing a phone just after 1+ yr isn't normal.  Its like changing a new car after 3yr because it doesn't start... And even a "cheap" smartphone is ~$400.  Any just released phone is $800-1000.   If you believe dishing-out $500-1000 each year for a phone isn't drastic, well...

-I may have access to another SIM card.   But the issue is that my problem occurs suddenly and randomly, it can work fine for a week..  So I can load new SIM - but SIM testing may take a long time (and I'll be using someone else's tel#).

 -I guess testing by powering down, removing the SIM card and flushing SIM data is worth a try... I will see if this "cures" my phone.

My previous phone, a Samsung Galaxy S3, is still being used by someone else at home.  It must be nearly 5-years old.  So if there is problem with my LG G3 after such a short time.... I will let everyone draw their own conclusion...

I'll report back after use BobTheElectrician's test.

The scuttlebut regarding the G3 is that some of the soldering on the motherboard left a bit to be desired leading to intermittent contacts some time down the road. Heating the contacts seems to have solved the probem for some, but that's a little drastic and unorthodox.

There's also been more than a few complaints about flaky SIMs recently, thus my suggestion. You can also gently clean the contacts before re-insterting. I would also consider replacing the SIM first before consigning the handset to the oven or a repair shop.

@A: on promo, you can get $200 phones nearly for free on new activations. Mid-range phones will cost you half price. Higher end phones will still get you a 50% discount on promo with Koodo's activation credits on new activations or upgrades (at least a month after release).
Nothing wrong with riding out an older handset, especially for the tech-savvy who install ROM's on 'em. You can still get good juice out of an older device.
On the flip side, we live in a society geared towards disposable goods. It's often cheaper to replace than to repair phones, bicycles, sometimes even cars, clothing, shoes, etc. It's no surprise that when a phone dies, it's probably best to trade it in at Wow mobile on a Koodo upgrade. Otherwise you could sell it for parts (probably get less than the trade-in at Wow mobile), use it as a coffee mug coaster, etc. This is why manufacturers give a one year warranty. If your phone outlives a year, then you're doing something right!
If a factory reset doesn't fix the problem, since you're past your one year warranty, you can look into flashing the original firmware (slightly more aggressive than a factory reset), or even installing a custom ROM (will likely give better performance on an older device).

There's a limit to the amount of effort and expense to be put into a handset that sells for $150 used and is 4 generations behind cutting edge. Manufacturers rely on this.

FWIW, I usually buy a 2-3 year old refurb unit for about a quarter to a third of the original new retail price. For those of us who don't need the latest gimmicks, you get a unit that been tested and fixed using an Android version that is pretty well up-to-date for around $200. Of course, your tastes and needs will vary.
