[G2 Q&A, Help & Troubleshooting] ricardo99:
Yes, unfortunately. I have an Elixr 4g widget switch set up on my home screen to easily switch it back to LTE. It cuts down on the number of screen presses and is better than dialing the secret menu each time. I was hoping for some Tasker automation but I can't seem to find anything just yet.

Not ideal, but it'll do until I decide whether to install a custom Rom.

The issue with the three network is in the lg g2 firmware not with three. Three haven't given their 4g lte settings to LG yet thats why you can't get the setting. Until they do you will have to do it manually.

[G2 Q&A, Help & Troubleshooting] wtfman:
I switched network provider today for fun and noticed that even though I bought (what I assume is) a Lyca 4G sim with 4G data package, I don't get the 4G option on the phone.

I've used one of the codes and activated it, the 4G icon comes up, flashes data but doesn't seem all that much faster than 3G.

I switched back to my 4G giffgaff sim which has no 4G access at the moment and 4G/LTE appears as an option in the settings.

Can I assume that my Lyca sim isn't an actual 4G sim and the secret menu just masks 3G with a 4G logo?

My phone is from Taiwan and I used it in Hong Kong which automatically switched the network to 4G (and the language to Chinese!) and it was stupidly fast. The current speed still lags when loading web pages as it would on 3G

[G2 Q&A, Help & Troubleshooting] MrBlondBE:
Still no 4G (or 3G) after all this! What to do???

Hi there,

Did anyone maybe fix this?

I too have the D802 originally from Asia (it had the D80220b-HGK-XX software version) and it had no LTE option enabled.

I changed the build.prop file: changed ro.telephony.default_network=* to several numbers (8, 9, 10, 11, 12) the options became enabled, but still no 3G nor 4G/LTE connection was made.

When I looked at the visible networks by the phone it could not find any 3G or 4G network. Eventhough I have the same sim card in another phone making 3G and 4G connection (so it's not a network issue)

I live in Belgium, and here they use 900MHz and 1800MHz for 4G (by my carrier Base) which is supported by the phone (hardware). I have set up my APN correctly (even checked by operator, who could not help me any further, neither does LG)

I have tried a new rom D80220d-EUR-XX, which I presume was intended for Germany, an open version. Still no luck. LTE option was enabled, but no luck on connecting to the actual networks....

Installed another Rom: Cyanogenmod 12, same options (and more) are available, but no 3G nor 4G/LTE connection is made, or can be found.

I've used all the other codes:

3845#*802#

*#*#4636#*#*

none of these fixed it for me.

Am I still the only one with this issue? Has anyone fixed it? Please help

PS: phone was brand new, so i don't believe it was sent broken... :s

[G2 Q&A, Help & Troubleshooting] MrBlondBE:
Hi RyanDre,

No, like Murshad007 pointed out. In our case, probably the phone is fake and the rom looks like it has the 'right' SW but its probably fake.

I sent mine back to china with a reimbursement from the seller (aliexpress protection) and bought a G3 instead of the G2 somewhere else.

I've been to the full extent of trying to get the G2 to work but it was not possible, so maybe try to get your money back as well...
[G2 Q&A, Help & Troubleshooting] Murshad007:
Why U can't even 3G? Do u have a 3G /4G Sim? Is it Enabled from your carrier? Are you in 3G 4G zone? Right APNE settings should be present in phone.

Do you have the option of LTE/WCDMA in mobile networks - Set Network?
[G2 Q&A, Help & Troubleshooting] MrBlondBE:
Murshad007, I have the G3 now working with the same sim card as I used with the G2 and have 3G and 4G from the beginning without a fuss. The fact that I could not even receive 3G anymore (whilst I did on my iPhone before I got the G2) made me think that the phones hardware was not as it should be. So, as you said, the phone is probably a fake one. Better send it back and find a better supplier. Good luck.
[G2 Q&A, Help & Troubleshooting] Murshad007:
I didn't Said that the phone is fake. I said refurbished. Frankenstein parts.

And manipulating a D801/D800 rom into D802. In Pakistan D802 is high in demand due to Band 3 1800MHZ. Both Pakistani 4G/LTE enabled carriers have this band. So all other models of G2 which don't have Band 3 is low in demand. That's why shopkeepers keep purchasing these refurbished D802 which ain't D802 actually. And even a original D802 which isn't open is limited by carrier restrictions on bands. So If some one have the band physically in the phone it will be possible to unlock it.
[G2 Q&A, Help & Troubleshooting] RyanDre:
I can only get 3G if I am in a major city (which I think uses 2100) but most of the time I am not in a city they have 900mhz and I cannot get 3G. Its is a 3g/4g sim which works in my wifes S3 and my old S2, and I even got a new sim card to be sure. I confirmed carriers APN settings and I have tried other APN settings as well. I have also tried my wifes SIM card which is on a different carrier and have same result. Only 2g, no 3g. So I think there must be a problem with my phone recieving 900 frequency. In hidden menu i can click 900mhz and it says sucess but it doesnt get any signal. i have never recieved 4G either, not even in the city.

Yes thanks I have tried all that. I have found something new though. I went into network selection and have been able to see both Vodafone GSM and vodafone WCDMA. I previously could only see Vodafone GSM. I click on Vodafone Wcdma and it tried to register on network but says its unavailable at this time.

[G2 Q&A, Help & Troubleshooting] RyanDre:
I have found that my wifes simcard with 2degrees network works. And my sim card works in her s3. So there is some sort of incompatibility between my vodafone sim card and my phone. Strange as both vodafone and 2degrees use the same 900 and 2100 frequencies
[G2 Q&A, Help & Troubleshooting] Murshad007:
It's not about incompatibility. Carriers often software block Mobile sets because they have paid a huge price on it. So they simply don't want their user do enable it on other networks. However it's a soft lock. You can enable it.. With correct settings and rom..

I'm currently using CM 10.1.3 STABLE with the radio included in the latest JB update for the UK. However, with this, battery usage when using mobile data is terribly high (I've tried two different batteries) and is eating about 1% per minute, even I know that's ridiculous.

Are there any suggestions?

Thanks.
[Galaxy S II Q&A, Help & Troubleshooting] Hopper8:
Yeah, you need to use the one which gives you the best signal. That'll then be the one with the lowest battery drain as your phone isn't searching for a signal constantly.

To do that, test the modems released by your carrier for your region /country. If you still don't find one that works for you, flash whichever one takes your fancy. Don't flash modem +RIL as you're on custom rom, you want modem only.

The other thing is, have you installed betterbatterystats? My guess is that it's something eating your battery, not the phone searching for signal. Find the xda thread for it and follow the instructions in the OP to figure out what's causing the drain.

[Galaxy S II Q&A, Help & Troubleshooting] kona144:
Did you try and delete the batterystats.bin in /data/system. ?

And try recalibrating your battery:

-Recharge your phone,

-Use the phone as you normally do and let it Discharge,

-When it Discharges and Turns off, Recharge it again,

-Do that for 2 days.

Maybe it will work, im not sure try it. But as i see i think that the batteries are weak or something. You know the batteries have some sort of a self remembering method that remembers the usage and Discharging of a battery.

Spotting a weak battery

I found it here.

Cell phone shuts off

If the battery’s capacity has shrunk, it will still read "full" even if there is very little power in it, and the phone will quickly run out of energy and turn off. Or, the phone could be at fault. Borrow a battery from another phone of the same type; if the phone works with the other battery, it’s time for a new battery.

Charge does not last

A cell phone battery should be good for around 24 hours between charges. Dramatically decreasing battery life is a sign of a dying battery.

Swollen battery

Sometimes swelling is visible even with the battery in place. To test for swelling, remove the battery and place it phone side down on a level surface. If it can wobble or spin, it must be replaced or it could begin to leak and damage the phone.

Hard spot

Squeeze a battery along its phone-side edge; if it has a hard spot, replace it.

Visible corrosion

Check the contacts for corrosion or other damage. If this could be a result of water damage, the battery should be replaced as further damage may be hidden inside the battery.

Water damage indicated

Cell phone batteries often have an indicator strip that changes color if water damage has occurred. Some cell phones also have such a strip inside the battery area; know what color the strip should be and what changes indicate damage. Damaged batteries should be replaced.

Excessive heat

If a lithium ion battery gets unusually hot during use or charging, it is getting worn out and should be replaced. Nickel-based batteries normally get hot during charging, so this is not a trouble sign for them.

Hope i helped you. :)
