Constant network issues

I am on my 3rd device in 3 days. First one was rooted, second one was not. This current one is also not rooted as well.
Unless I am very unlucky, I am going to assume there is a definite issue with the network configuration on this device. Status says I have 3 bars of 4G coverage, however I cannot connect to the internet at all.
Network Signal Info says I am on UMTS with a -93DBM, data is connected. However nothing will load. If I put the phone into airplane mode and then turn airplane mode off the networking comes back online. Speeds are slow though, barely able to perform basic mobile web browsing and watching youtube and such isnt possible. Too slow an too long to buffer.
This doesn't only happen at my house, it happens in other areas as well but it does happen constantly at home. I a not a heavy data user on my account, 1-2GB monthly, so Tmo says they arent throttling me. They have replaced the SIM every time with the devices as well.
Suggestions? If I cannot figure this out soon I am going to cancel my service as I cannot pay for a service and phone that just doesnt work. Tmo seems stumped. They just keep replacing phones since I am within my 14 day return/exchange period.
However, 3 devices all having the same issues sure seems to either prove the phone has an issue, or m general area of Tmo service.
I live in downtown Tempe, AZ.

Your wifi works?
I have the same issue in my house... I have a weak signal and 4g drops down to 2g which is terrible.... 4g downloads are 3Mbps, but uploads are under 100kps
I changed the network mode to wcdma only which helps significantly. 4g drops, but quickly returns...
Give it a try...

I'm having the same issue here in Orlando. I've had 2 phones now (first one was just a bad unit) and both have had horrible network connectivity and reception. I take my SIM card out and put it in my 2 year old MT3G and it gets perfect reception and fast data transfers while the G2x is choking on network transfers.

Go complain here in LG forum. This is software issue.

have full bars but cant download anything. just sits at waiting for data connection.

We really need a baseband modem that works better. My bars goes to zero then to edge and then to 3g constantly. Any time it switches between the connections then the the bars goes to zero and it says there is no conection. Also noticed that 3g connection fluctuates very bad while doing a speed test.

How are you getting 3g? Unless you meant to say 4g?

T-mobile only has 3g connection avaliable where I live, of course it says 4g on the phone but in reality it is only 3g.

I wonder if there is an issue with our network in Arizona?? I live in Chandler, and work in Scottsdale. my data times out ALLL THE TIME. Both here at home, and at work. Same with my text messaging. Literally, I do exactly what you do with the "airplane" mode. That's the only way to get my data and text working again (besides restarting).
Here are the issues I posted in the LG Forum:
http://www.lgforum.com/forum/boards/carriers/t-mobile/topics/few-issues-with-g2x#26861
(first issue posted is what you are talking about)

I dont think this is a regional issue. Downtown Minneapolis here, and I cant get it to stay on wifi or Edge/4g for more than a few minutes at a time. G1 has no trouble and shows strong 3g while my sisters mt4g shows full 4g. 4g/E symbol just flickers on my g2x leaving me with no connection. I can connect to wifi fine, but even with wifi sleep set to never it still disconnects every few minutes, and has to be toggled on/off to reconnect. Until toggling it just sits flickering 4g/E with no data connection.
I've never seen my Evo drop a E/4g/wifi connection and struggle to reconnect once in the year I've had it. My g2x does it almost every time I pick it up.

Did you try going into Mobile Networks in Settings and changing the mode to WCDA Preferred or something? That'll stop the flip flopping. That's what I have it on and that's what the phone came with out of the box.Also try Auto in that menu.

Network goes inactive when it shouldn't?

I've had several occasions when it feels like the network just stops doing its thing when it should still be active.
For instance, when updating my apps, it will update most, and then get stuck at 'downloading' one of the last few apps forever (keep in mind these are tiny downloads we're talking about).
Another example would be Facebook. There are instances when it seems like the network isn't activated or doesn't remain active when I try to view an image. It would get stuck at the loading stage and never get out of it unless I reload.
I'm starting to think this goes beyond a simple application bug and probably is firmware related? Anyone else have a similar issue?

Well I've had similar issues with my One X (AT&T). I definitely have the WiFi issue that some folks are talking about. I've had WiFi just kick off and say "not in range" when I am standing right next to my router.
With regard to the network, I have had multiple times (at least 5-6) where out of the blue I get no signal of any kind and have seen it last as long as 5 minutes, even when I moved around (at one point I walked for 5 blocks). This was in a large metropolitan area where I have never had a signal problem. My friend was with me and had no issues at that time on his Iphone 4 with AT&T.
I went to Best Buy yesterday and was lucky enough to have it do the same thing while they were looking at it. I'll probably return it for an exchange just in case it's an issue with this specific phone.

I am having the same issues as well - although it rarely happens. I will likely exchange it for another.

Similar issues here.
I seem to be suffering from all of the various bugs. Wifi, network signals, email push. When you add in the things that are apparently there by design, but might as well be bugs (multitasking issue; links to youtube and appstore opening up in browser windows instead of the app), I'm pretty dissatisfied with my overall experience.
Hardware and screen absolutely fantastic. Software... way buggy.

Same here for all of the above. Love the phone 95% of the time, but it does random things (like drop network connection) 5% of the time that drives me nuts.
Has anyone ever seen it switch to 3G? Mine will drop to no signal with 4G still displayed when I know there is plenty of 3G coverage in the area...

honestly i thought the facebook one was just a facebook problem... because i've had that with every android phone i've ever owned across two carriers (T-Mobile and AT&T). it is annoying though.

Nope. Happens to me in all programs using data. I also had the same issue with Facebook on past android phones, but that isnt the problem this time.

So is it safe to say its most likely a software/firmware problem? I got my phone through Amazon so exchanging it is more of a nuisance.

I am pretty sure this is a firmware issue. Remember, this is the first ICS HTC phone. There were bound to be bugs.

I don't think this is faulty hardware given how many people are having issues and given how my similar issues have seemingly disappeared. I believe it is a combination of software just AT&T's network. I don't think their network is quite as ready as it should be for this phone. There aren't many LTE devices on AT&T but the more there are the more issues there's bound to be unless they move at a slower pace and work them out. I mean it's just a logical trade off between having a network that grows very steadily vs. one that spreads rapidly to capture more attention and users. They want to roll out LTE to as many cities as possible, but they could simply be doing it cheaply (edit- there is NOTHING cheap about it, but let's say "more cheaply" than a slow and steady approach). From what I've read on the interwebs there they don't have complete coverage in certain areas, they skip a few towers So overtime, I would expect this issue to get better through software updates for the phone and just general network infrastructure reinforcement. Also keep in mind they don't have volume testing, only spot testing. Download the AT&T app that lets you report when you don't have good signal. It helps them.
https://play.google.com/store/apps/details?id=com.att.android.markthespot&hl=en
Too bad they didn't pre-load this app instead of all the others
Also worth a mention that AT&T took an interesting path with their "Circuit Switch Fall Back" (CSFB) system and I'm fairly certain it's a bit more complex than it sounds...I would be willing to wager several firmware/radio updates will come out in the future to help improve how this works. If I was a betting man, I would also bet that getting dropped from their network would be a result of this in many cases. Of course bad signal is a very common and simple reason, but I also think it would be foolish to assume CSFB would just work without any glitches. Although I do like the idea vs. what Sprint is doing (which is I'm sure not their preferred solution, but I guess buyer beware when it comes to these big companies investing in major infrastructure matters).

ROFL - I loaded up the Mark the Spot app and realized it said at the bottom "Don't use this app while driving." ... Not sure I've seen that before on an app, but what a nice responsible thing to add. I'm sure they of course mean don't use it while moving fast because your position won't get accurately marked...But eh it's nice to think they meant it for safety.

Latest Radio from Update: Good or bad for you?

I've found the latest JB radio update to be far worse than the original radio that came with the phone in terms of texting and calling in medium/low signal situations. In fact, most calls disconnect after a few seconds and most texts fail to send while other phones have no problems.
How have you guys found the latest radio update (K3) to be?

I think there is a thread about this already, but I'm with you. I had 6 dropped calls in one day after the update in an area I used to be able to use my phone no problem. Verizon told Mr I had to turn on GPS and Verizon location services for there network to "find me" to use there network. When that obviously didn't work they are sending me a replacement phone.
If I helped you in some way.... pass on the favor and help the next person!

Hmmm...I'm actually getting more bars in my room now than I had when I was on the original radio, that I had from my pre-ordered phone. I also haven't had any dropped calls either.

I've realized that bars mean absolutely nothing with this phone - I mean, sure, number of bars usually don't reflect the real signal meter but with this phone, but on this phone, it really means NOTHING. It will give me 3 bars while if you go to the status of the phone, it says No service and a call cannot be made. Might have a few bars but texts immediately fail repeatedly....
Drives me nuts.

I thought it had gotten worse, but I tried the HE and the K1 and they equally were sucking for me now too. I'm not actually losing connection to the network but it continously drops from 3 bars to 1 or 3G just sitting or in my pocket.
I love this phone, but am hating the data reception that seems to be getting worse for me.

The Verizon rep told me the same thing that the bars mean nothing. I don't pay attention to the bars or the dbm, I just load a webpage and see how it crawls suddenly. If I feel like I'm back on my Droid Incredible, I notice there must be an issue.

I find the best radio for voice to be I5 - the first JB leak. I find the difference to be extremely noticeable. HOWEVER, on the downside - I feel the 4G isn't as strong/drops to 3g/1x more often? Not sure.

Yeah, you're right that bars really mean nothing, but I was just saying that it shows more after my update. But like I said, I haven't had dropped calls yet. I will find out more as I travel in the next few days.

I haven't had any dropped calls on the new radio.

The new radio actually works a lot better than many of the old ones. I concluded that HE was the best radio for my device, however upon flashing K3, I stopped experiencing 4G data drops and the 4G/3G handoff has gotten significantly better..so for me, its been pretty good

S6 Switches from LTE to LTE+ Whenever Modem Takes Load

Hi all,
Just got my brand new S6 in white a few minutes ago.
I loaded some tests that I always do when getting a new phone, one of them is the RGB dead pixel test, this is a youtube video I run. I noticed as the video was loading that LTE switched to LTE+ momentarily and then switched back to LTE. This appears to occur anytime the modem is about to load anything with some significant data behind it. Is this normal?
It is slightly annoying to see a flash in the status bar every time the phone shifts, but of course, I can bear it if it's appropriate. I am just worried these switch offs are a sign of weak modem signal (the network is strong, I see full bars in LTE regular mode).
Please advise, the gustapo here only allows me to return the phone if I don't talk on it for more than 15 minutes. Everything else looks in order, just want to ensure this isn't an issue so I can use my dang phone!
Thanks so much!
PS: One last thing, does this thing ever get hot! Upon doing a system update and installing all my apps I could barely hold the thing without massive hand sweat, is that normal? I believe it is an unfortunate side-effect of having such a powerful set of cores. Thanks again!

Anyone? Can anyone chime in about the heat at least? Thanks very much!

I think this is more of a network issue than a phone issue. The phone will always switch to the more stable consistant network speed, especially during heavy data transfer. Also the cellular network has a limited number of LTE+ slots on a given tower, which can result in frequent switch over.
The download performance between LTE and LTE+ should be neglegable anyway. It's the latency that mainly differentiate the two.
You could try disable "smart network swich" in the WiFi settings, but I doubt that would help, as that is more geared toward WiFi and cellular data switching.

Heat wise, it's normal for modern multi-colour devices to get hot during (even moderate) use.
My old HTC Sensation used to get hot to the touch when under heavy gaming or even Web browsing.
I'm waiting for the day that mobile phones come out with fans or liquid cooling! [emoji14]

A factory reset has been known to cure this for others. YMMV

List your issues!

So guys anyone having issues with their phone? List them and if anyone can help resolve it then reply! My list would be:
-Weak wifi signal (even when I am in the room right next to it)
-Weak signal for data
-Phone gets randomly hot
These could possibly be software bugs but thought I list them anyways

So far, I've only noticed that when I go with the Material Black theme, Messaging app randomly will go all black save for contact name at the top with no keyboard. Have to close out the app and re-open. Doesn't happen with my current theme (Vanilla) or stock theme. One other user had this issue as well....however this seems to be something in the theme rather than the phone itself.
Has only gotten relatively hot only once when Amazon Photo decided to back up all my sdcard to the cloud (60+GB of pics n vids which had never backed up from my G4 I took it out of). Took over an hour and phone got pretty warm.
Neither are really an issue for me, as I don't use the Material Black theme any longer, and the photos are already uploaded so no more mass uploads.
Overall loving the phone. Last charge went 30+ hours with good amount of calls & music streaming thru Bluetooth and about 3hr screen on time.

I took it off the charger one day and it got really hot. I left it alone and came back to it and it was too hot to hold. I reset the phone and it fixed whatever the problem was. Other than that I've had no issues so far.

That's probably because of the fact you used the quick charger. Since it's rapidly charging the battery, the battery can be warm to the touch.

I also noticed when I send or reply in a group message it says sending even after the group or individual received the mms. Weird.

Samsung Pay doesn't work, I've tried it over 10 different times.
Phone gets really hot.
The service signal fluctuates from full bars of signal with no internet, to 1 bar of signal with 4G internet that's unusable. (This happens in low signal areas).

I get this issue every single day! Usually a no cellular network available but it shows 4g with 2 bars?

Anybody having the settings crash when trying to configure do not disturb?

Nope got it set easily

Download Crystal.

I've a long house and have access points at each end. The phone stubbornly sticks with one (Asus RT-AC66U) regardless of signal strength. The other is an older TP-Link AP, even when I'm almost on top of it I have to manually switch. Any clues on how to get it to pick the strongest signal? It's a small nit, otherwise this is one of the nicest devices I've ever used, I'm coming off a Nexus 6.

Having a problem with notifications while connected to wifi, as in, I get none.
Once I disconnect, my phone is flooded with all the notifications I've missed.
I've tried changing channels in my router, renaming, switching between 2.4/5GHz, etc, but nothing. Problem persists.
Ideas?

Mine keeps dropping connection and losing 4g also my sd unmounts every 20 minutes im getting ready to throw the thing at the wall.

Which brand SD you using? I know that there seems to be some sort of issue with Samsung cards with this device.
Also, is the tray exactly in correctly? I'm not being condescending, but if you're not careful, it can go in slightly cockeyed(noticeable as the "door" to the sdcard/sim tray will not be flush), which can cause it to not make good connection.
Throwing it at the wall will provide 0.25seconds of "Yes! Take that!" followed by "Um....insurance or replacement is expensive as $h*t" LOL
If you DO choose the "throw it at the wall" option, please video tape it so that we can see the "wall impact resistance" of the device

WiFi calling is off, one of the first settings changes I made as I very rarely make voice calls.

Get really warm for me as well and LTE download is about 50% slower than my previous S6 Edge. I didn't used the new sim card that came with the phone so maybe that's the problem.

Did you download an update for Samsung Pay when you first set it up? You might have to do that before it will work. You should have version 1.7.04.
