Hey guys, I recently got a S2x a few days back it's been great however I've run into a problem today..
I tend to disable 3G/data to save battery and stay on EDGE however this afternoon after I turned on 3G again, my phone just doesn't connect back onto 3G and is stuck on EDGE..
Does anyone have a problems like this?
EDIT: apparently my provider's 3G network is down.. this might explain it..
Thread close!
I just bought a T Mobile LG G3 (D851) for use on AT&T. The guy I bought it from got the unlock code from T Mobile and that is all squared away and unlocked. Things are basically working on AT&T, but data is not working reliably for me. It works fine for awhile, then it just stops working--the 4G/LTE logo in the status bar disappears and I have no connectivity. I can still make phone calls and send/receive SMS texts (though no MMS texts), and if a wifi network is around, that works too. Rebooting does not seem to correct it (though it does start working again eventually).
I don't know if it is just random, but it does seem to happen after I'm leaving somewhere with wifi (and that may not even be relevant--might be that's just when I notice it).
I have verified my APN settings (as well as tried other slightly different settings I've found around the web), but the data network still drops out. Yesterday, I discovered a technique that seems to reliably bring it back on after it has dropped out. If I change the Network Mode to anything else (ex: just GSM), then back out of the network options menu... then go back in and set Network Mode back to LTE (etc). Every time I have tried this, I get the 4G/LTE logo back in the status bar and my connectivity is back.
I know there is some difference in the LTE bands supported by AT&T and the T Mobile LG G3 (D851), but the phone supports band 17, which I'm told is the main LTE band used by AT&T. At this point, I think I'd be satisfied just to have consistent 4G (non-LTE) data.
Any idea what might be the issue? Or anything I can try out? I'm considering flashing a different rom to see if that helps, but wanted to exhaust other options first.
Thanks...
Hello!
I have a big problem with my G4 (H815 version, Germany) beginning with the switch from CM13 to the (stock based) Genisys 3.2 ROM. I've tried to fix it for three days now but without success. It doesn't stick to LTE anymore like it should do and did before. After a reboot it does sometimes connect to LTE but after switching back from wifi or airplane mode it's showing the "no signal" icon. Then it takes some seconds until it reconnects to the mobile network but now just to 2G or 3G. From this point it's not willing to reconnect to LTE, even not through the manual RAT-selection. "Force LTE" using the hidden menu then results in no network connection. However, after restoring my EFS-partition-backup with TWRP (from a time when it was working perfectly) it's connecting to LTE directly after boot but only once and only until you toggle wifi or go offline - like described before. After the next reboot it will mostly connect to 3G and then maybe switch to LTE sometimes or not.
Of course I have checked, deleted and restored my APN multiple times, I have also recovered to a stock V20b and V10d .kdz using LG UP in refurbish mode. Unfortunately even on the fresh and untouched V10d install it shows the same strange behaviour. Restoring the CM13 backup (including EFS partition), which has worked perfectly before, shows the same network bug now.
My sim-card is still working perfectly in my other phones. It still connects and reconnects almost instantly to LTE in my old S4 in places where the G4 did the same but struggles now.
I have even tried the cdmatool which is used to unlock additional LTE bands. I didn't change anything but it does show all usual LTE-bands which are needed for my provider.
Does anyone have an idea what I could try next? I'm living in an area with much better LTE than 3G connection and paying for a quite expensive LTE contract so a working LTE is very important for me. If I don't get that to work again I would need to replace my just over one month old G4 :crying:
Many thanks in advance for your answers
f-rouz
Meanwhile I have also tried another simcard. Still no LTE
i have the exact same problem, well, almost. no unlocked bootloader, but when i first got the phone i root injected the system.img and flashed away, thought everything was fine. now it just doesn't reconnect to 4G. well, at home at least. on my S4 i get 4 out of 5 bars on 4G, with the G4 i get 2 or 3 bars out of 5 on 4G, so the signal isn't great but good enough. i live in hastings (a town) and went to brighton today (a city) where the signal is max 4G, and the device does pick it up. but as soon as i go through a 3G area to home, it doesn't reconnect. have tried flashing original system.img back, upgrading to MM 6.0 after factory reset (via LG bridge), then downgraded again to V10c via LGUP - factory reset before the downgrade, no joy, still the same.
when you say you have forced LTE in hidden menu, did you try this - enter 277634#*# in dialer and go to field test > modem settings > lte band selection and select the band for your operator, which can be found on 'wiki europe lte bands'. there were two bands for my provider (three UK) and band 3 was what i wanted. i can now switch to 4G but it's a pain having to this every time i come home ( i use my phone for home internet via tethering).
worst part is, having refrained from unlocking the bootloader to save the warranty, i phoned LG today to send it back as faulty and explained i could switch it to lte band 3 via the hidden menu and they told me my warranty was now invalid as had OPENED the hidden menu (they told me this after taking my imei). so if anyone reads this and phones LG for a repair, don't tell them you have accessed the hidden menu if you have done what i did.
think i'm just gonna sell the phone, make a palpable loss and buy another one, as i love the phone
Wow, I haven't thought that from LG. I feel like I've searched the whole internet already and nobody has a solution to this problem. I'm about to send my G4 back to Amazon (or sell it otherwise), hope the best and get myself a Oneplus Two because the G4 seems to be too *****y from the development standpoint. I've never had a situation like this with my previous Samsung phones since 2009. I will miss this camera though. And the NFC and the wireless and fast charging capability... the G4 is a nice phone nevertheless...
Edit: And yes, I have tried the "277634#*#" hidden menu, although it isn't accessible through this code on MM any more (you need a terminal command to start this).
Have you tried limiting it to 4G/2G in hidden menu? Mine also have a similar problem in Lollipop in that it is very aggressive in dropping to 3G. That worked for me. Phone doesn't drop to 2G much provided you have decent LTE coverage.
Now I'm on Marshmallow and not rooted, thus cannot do the same. Though it seems to be sticking to LTE a bit better than before.
I have tried that but it doesn't work. As I don't get any network connection wenn forcing LTE only, forcing LTE/2g results in 2g only.
My G4 still doesn't want to connect to LTE so I have ordered a S6 now... As I still have no idea what was causing this I just can't risk that happening again. It has been a short journey for my first LG and me and I really liked my G4 actually... Bye G4 community
you just needed to flash the stock modem, most likely
Unfortunately, it isn't that easy. That was of course the first thing I did (and not just one time)...
I just got a new Zuk Z2 today. I'm using Straight Talk w/AT&T and I get no signal what so ever. My old phone has 3-4 bars of HSPA signal on said network. Anyone know if there is a trick to getting this to work or is the new phone a bust?
Same issue with me too.....help asap
alot of people has this problem, including my self, nice phone but **** hw
I having lenevo z2(2132) , but no network signal on phone, I tried all CN ROMs 1.9 than 3.1 but nothing helped to get network no 2G , 3G, or LTE, I can see my imei no. Correctly , wi-fi works also. But no network at all. Restored XCNN. Files also from zuk forum.
Phone is rooted with TWRP now. If any...
Solution...
Thanks
Just checking to see if I am the only one having these issues.
I have the 3 XL on ATT, and I randomly have no internet access over mobile data, even though the notification shows LTE and decent signal strength. Screenshots attached to show what I'm talking about. This has happened about 4 or 5 times since I received the phone a few weeks ago. I went to ATT and got a brand new sim, thinking that my old sim may have been going bad, but that did nothing. Only way to get the mobile network connection working again is to reboot the phone.
I have also noticed a few times that the squeeze for google assistant feature will stop working, and I have to reboot the phone to get it working again. Anyone suggestions? I am leaning towards just doing a factory reset this weekend, but I would like to avoid that if possible.
Thanks
dont know about the edge squeeze assisit not working (i use edge sense module and app) but i have to reboot or go into airplane mode to get data to work when i get the x. maybe using a different apn would help... im on att too
AT&T issues
This is now a problem for me. I have to put my phone in airplane and then back to lte at least once a day in order to get mobile data working again. I'm not really sure if it's a network issue or a phone issue.
Issue for me here too, but I'm in Australia on Telstra network.
