Sprint tech support is terrible - help me

I'm at home and for the first time since the EVO came out the phone is going from roaming to zero bars to 1 bar to roaming in a VERY fast manner. There is no consistency with the connection anymore. I can't even surf. My family in the same house has EVOs which are totally fine.
Sprint says pull the battery, then the idiot hangs up and thinks that could solve the problem.

I talked to a rep over the online chat when I had to activate my Evo, and they were very helpful. Try that or call back and hope you get someone more helpful. The antenna is on the back of the Evo on the side of the LED flashes on the top half. If you need a picture, you can find one in the Evo manual. Put two of Evos next to each other and compare the signal without touching that area.
If it does turn out that it is just bad coverage this hack could help: http://forum.xda-developers.com/showthread.php?t=696073

[Q] No reception

I rooted my G2 about 2 weeks ago with Virtuous ROM and, the other day I picked the phone up to go to work not thinking anything was wrong.
When I got to work, I had an X where the signal bars are. Tried to turning phone off and, nothing.
When I go in and search for the carriers it shows T-Mobile and AT&T listed then I tap the T-Mobile section and it tells me "Your SIM Card doesn't allow connection to this Network"....So we called T-Mobile and switched SIM Cards and still get the same thing.
My SIM works in every other phone we have, including our myTouch4g...I have un-rooted and, same result. Then rooted again and, it still acts the same way..
T-Mobile said it was something with their network and, could take 3 days to get it straightened out.
Has anyone else had this kind of problem out of there G2 before or after rooting?
I'm in Tennessee, if that helps.

Well, I went totally back to stock and, still no reception. Just an X in the signal location.

Send phone in for warranty if you have it...and try to enable raoming and data raoming and see if you can pick up any signal...

Thanks. I tried that and, still no signal. My DBM is -109 when I checked it a few minutes ago through the my device app.
Checked it again and it says -89, signal strength of 14 but, still have an x on the signal bars.
This is crazy. You don't think the Virtuous ROM messed it up do you?

I got a solution from T-Mobile. They are sending me a new one.....YIPPIE

[Q] Signal issues.

I've had my G3 since last week and I'm starting to get very frustrated with it. I have absolutely no issue with the phone itself. Its snappy, screen is beautiful. UI is fine, and honestly I don't even feel the need to root (yet)
My problem is the LTE on the phone. I have my phone USB tethered to my PC in a window to give me high speed. We only get dial up where we live and LTE is the only source of highspeed available. Frustratingly during the day between around 11am and 8pm Its like pulling teeth to get the phone to stick to LTE, every 1-5 minutes it switches down to 3G and stays there until I put it into airplane mode and back. Then LTE pops on again and its fine for another 1-5 minutes. During the night it will stay for hours. I've even taken off the back case to somehow eek out a little more signal strength.
Now I know that this could be a provider coverage issue, but my mother's Galaxy S4 stays on LTE even during the daytime and has one more bar of signal.
So before I throw the phone across the room in frustration, I was wondering if anyone knows of a way to change the LTE/CMDA settings beyond the crappy preference options (that doesn't work) in the mobile data settings. I can access the hidden menus but I don't know what any of it means. Is there a way to force LTE on permanently, or disable 3G data. Are there any nice network diagnostic tools to track signal strength as I move the phone to different areas, or compare it with other phones?
I love this phone but if I can't find a fix I may have to replace it with another device.
TL;DR: Need help getting LTE to stay on, settings or tool recommendations welcome.

I have this same issue!!!
Hey I know this isn't an answer to your problem but, I wanted to say you aren't alone by any means and I have also tried the same things you have. This is very irritating and I called my phone provider (T-Mobile) and all they could tell me is to get a "LTE phone booster" so that is what I have done but now I have to wait like a week and a half for it to get here.... By chance have you found a solution to our problem ?

2. it is normal for every phone that if u are out of network...u wont get any bar...my phone also does the same...but the problem is....network bar should be back once u r in network coverage again...but my Lg g3 dont do that...i keeps searching for network....wont find any bar until i turn on Airplane mode den turn it off again...i m concerned..please someone help me :crying:

LTE and 4G (ATT H810) issues

Anyone else on the ATT G4 having problems with LTE connectivity? In areas where I'd usually get 5 bars of LTE service, a majority of the time I get 2 or 3 bars of Edge service. Putting it into airplane mode and back out doesn't help, turning mobile data on and off doesn't help, and neither does removing the SIM card (and reseting the phone in the process). It seems to come and go whenever it wants to.

All I can guess is, it's probably just the ATT network itself. They did some upgrades around here a while once Cspire started hyping their fiber optic network and I noticed on my older phone that in areas where I used to get 3G I was stuck getting edge. Even with my G4 I can park in perfect view of a known ATT tower and it'll hit 4G and within a minute be down to 3G - same with strength. Get 5 bars, don't move, no data, no call, and it'll drop down to no bars but still connected and bounce around, usually settling at 2 or 3. Even though ATT says they have full LTE out here I rarely actually see the LTE logo display in the status bar.
I've been using OpenSignal to try to map out coverage areas though, been pretty handy in finding towers and chasing stronger signal

Hi sir
I m using lg g4 h810 AT&T it was working well one day i put a memory card in it signal disappear never came go to software and hardware experts but nobody has solved my problem all other functions of cell phone working properly

4G not working(UK)

I was wondering why my phone always displayed the 3G logo next to signal bar so decided to investigate further. Despite living in the centre of town the 4G around here is quite patchy so I put an identical "Three(3UK)" 4G sim in my old Moto G 4G phone and went outside to compare...sure enough, the Moto G was showing 4G while the P8000 showed 3G. As far as I know I have never seen 4G in the display. The phone will be going back if I can't get 4G!
Anyone else experienced this or am I the odd one out?
4G is selected under preferred network type.

Have you tried Editting the APN settings to that for Three?

Go to dial pad and type:
*#*#4636#*#* that should take you to phone info. then on nework mode choose LTE only and see if it works...

APN seems fine, thanks for that hashcode @ferreinf - I will try that when I'm definitely in a 4g area near my flat

My brother has just got one and is having exactly the same issue on Three. Any joy?

Lol
I will Rek u after u read this

I drove to a 4g area nearby today and force enabled LTE only as described(you can also d/l MTK engineering app from playstore to do this) - I did manage to get the 4g symbol above the signal bars but a speedtest didn't really produce what you might expect from a 4g connection...the symbol did change back by itself to H about a minute later so I'm not quite sure what's going on here....I might have an old Vodafone PAYG sim somewhere so my next move might be to try it instead. Haven't got access to EE or O2/giffgaff cards to test. APN settings seem to be correct and 3g data does work quite well so it's interesting that your bro has the same issues, where did he buy his phone and what colour is it(does his have the blue notification led in home button?)

I think it might have been geekbuying, it only came today. Black one with blue LED. I got him to try switching to LTE only and he said he got a 4g signal but lost ability to make calls. I'm also on 3 but with a Honor 6 and I'm due to see him tomorrow so I'll have a tinker myself and see how his signal is compared to mine in the same location.

That will indeed be a good test, I was out again in another location tonight and noticed the 4g come on by itself so perhaps that's a good sign - I'll have to test the calls function when on 4g tomorrow but it should automatically revert to 3g for that surely. I am using the flyme rom by the way...my area is supposed to have 4g according to the coverage checker but it's bloody useless around here!
That Honor 6 better be good for $300 though you probably paid more at the time(did you get single or dual sim?),
I actually bought the P8000 for my wife but she finds it too heavy and the screen too big so I'm stuck with the big gold brick - at least the battery life is pretty good!

Tested the 4g again and it seems to be working better now that I forced it to LTE through the engineering menu and when you make a call it reverts to 3g then cycles back to H then 4g when you end call. Didn't test d/l speed as I had my payg card in and running a 4g speedtest burns quite a lot of data!
So how do you rate your Honor 6 against your bros phone?

4g just popped up on mine, got 25.3 down and 2.2 up. Not sure if that's good or bad to he honest.

That's pretty good I'd say, I would be happy with that! I flashed the stock ROM back today and forced phone to LTE and your bro is right about the calls not working as the phone doesn't revert to 3g for voice automatically so I might have to go back to flyme...hope cm ROM is here soon and that it works well!

Tried again today on stock rom not forced to 4G and the phone did pick up 4g automatically as I was driving around, calls worked too so it seems that problem has magically fixed itself as it wasn't showing 4g at all the first week I had it! Still getting the annoying random wifi hangs and camera crashes when trying to use with other apps(waze in my case).

there's an firmware update adressing this issue, dated august 15th. it should fix this.

Sorry, not been back to this thread since contributing before.
My brother is still complaining about internet speeds. When I sat with him I was getting H+ but his phone was just showing 3G. Tried to force to 4G only but that resulted in no signal (we were in a weak 4G area). So my main concern at the mo is that he might not be getting H+ and is only either getting standard 3G.
It's difficult to debug from afar, but I did all the usual engineering menu stuff when I was with him and none of that seemed to help. I'm seeing him again on Saturday and we'll both be in a 4G area so I'll at least be able to do some more comparisons...
Regarding my Honor, it's a lovely phone. I paid about £200 for the single SIM European version of it back in January. I had a Lenovo A830 prior to that so I'm a big Chinaphone fan, but didn't want anything bigger than 5" which is what made me go for the Honor. The P8000 seems very nice too though!
---------- Post added at 08:21 PM ---------- Previous post was at 07:50 PM ----------
I remember on my A830 having to flash a different modem / radio image to get the correct bands and I notice a similar issue with some import OPOs detailed here forums.oneplus.net/threads/modem-hack-for-chinese-opo-to-enable-3g.46696 - I suspect a similar issue might be at play here.
Might flash the FlyMe ROM for him at the weekend seeing as people have had success with that...

Hi,
I have 4G issue too but have yet to see 4G display once and I"m in a strong signal area.
I have configured my APN for giffgaff, data is enabled, 4g is "preferred" in options and LTE is forced in Eng menu as above *#*#4636#*#*
But still no 4g from my sim which is working as tried in another phone any ideas please?
what does the 3g with a smaller 3g behind it mean?
Regards
