4G problem - EVO 4G General

I did the fix and i am on stock updated all the way from one of the threads in the dev section and before 4G worked with the old radio but cut out all the time So i decided to do this fix and now the 4G connects for about a minute and it disconnects and i am in an area with excellent 4G coverage. So if anyone knows of a 4G connection problem in the Kansas City area please tell me or if it is just my phone tell me how i can fix this problem.
Edit: It appears that 3G cuts in to do data instead of 4G because as soon as it cuts out 3G uses data.
Edit 2: Now if I go in to Setting>Wireless & Networks>4G Settings It says fair - Poor connection, Assuming because i am inside, but i am not connected.
Edit 3: After disabling mobile data in the network settings it now holds the 4G connection well but now i have to wonder why 3G would over take 4G while it is on.

I been having 4g problems since the recent ota update. I hardly get 4g and it's considerably slower.. I'm running full stock with no root. What fix is available?

[Q] 4G Wireless Hotspot Success

How have people been fairing with this?
So far from work, my connection appears iffy at best. I can turn off and on the 4g to get one or two successful page requests through. I have a Clear Wimaxx Spot that I use at the same location (that I turn off before activating 4g on phone) with no connection issues. Also, my 4g only reports 1 bar. My distance from the tower is < .5 miles. I'll post an update when I try it from home.
Anybody know how to check 4G signal strength (other than generic bar readout) from the device? I've seen the signal strength in "about phone" area but am guessing it's dedicated to 3G - I could be wrong.
I'm hoping to drop my Clear Spot but so far, doesn't look like that's going to happen.
The hotspot app has worked great for me in 3G mode, but there's no 4G coverage here to try with that.
I'm also having the same issue. I'm in an area with excellent 4G coverage, but only getting 1 bar. Earlier I was getting spammed "4G has been disconnected" in the notification bar. I had to restart the phone to fix the issue.
Sent from my Samsung Epic 4G™
I've been getting the 4g disconnected message also.
I'm using a clear spot which should be running off of the same tower. I consistently get their best reception (throttled at 600kbps) from the same location. I've tried turning it off in case it's getting in the way already if anyone is wondering.
My 4G icon on the Epic typically reads from 0-1 bar. I'm under .5 miles and my entire area reads "indoor" 4g on sprints map.
I couldn't find any information on the strength of the 4g radio in this thing. If anyone has that info I'd appreciate it. I believe Samsung touts it as being 20% more connective than other devices...but that might just be 3g.
Hi, I am located in the downtown of a city with 4g enabled and I can turn it on and with a speed test confirm 4g is turned on (3Mb down). When I connect I get about 3 bars and can surf some web pages but it always eventually gives me "4g disconnected" I haven't been able to complete any download over 10ish megabytes on 4g because 4g disconnects and the download fails. i might call the sprint store later, but it seems like this would be software fixable.

EVO Not showing 1x / False 3G

Ok so I have been messing around with the evo and doing a new rom for the whole cricket thing.
One thing i have noticed while doing this is that the EVO DOES NOT drop down to 1x at all. So i decided to write a 1x PRL to the phone. The phone reports that it is ON 3G network. This is not possible and I think that is wrong. Sprint has the phone reporting that it is 3G even though its on a 1x network.
If his has been discussed please let me know thanks.

Sorry to deviate from your original message but is there a way to force 1x? I'm assuming 1x uses less energy than EVDO/3G; so if true, it would be beneficial to switch to 1x when idling/display is off. Maybe tasker or juice defender already does this?
Edit: On CM6 I hit 1x from time to time. At least the status bar reports it as 1x. Could be a Sense/HTC bug.
Edit 2: It seems that Android doesn't have a API for 3G/2G toggling. Sucks.
No your fine, Yes CM does go to 1x. This isnt based off a sprint rom. Its not a HTC Sense issue because I had ported a incredible rom a while back to the phone and it would drop to 1x. I just tried a new port for 2.2 from the incredible and its doing the same thing.
It is possbile that it could be a HTC Sense Bug in the 2.2 Froyo. But i really think that Verizon and Sprint are not wanting it to drop to 1x. Wich i think is wrong.
The way i forced it was to load a 1x PRL on the phone.
I'm connected as 3G "False" as i checked the speed now and I only got 39.62kb wich is far from the 1565.1kbs i checked before switching PRL.
Maybe you already knew this, but I'm pretty sure that for a 1xRTT network the 3G icon in stock htc sense roms simply greys out. At least that's what I remember seeing in the manual. When the phone is connected to 3G the icon turns white.
I don't know - I'm almost positive that I've seen a 1x symbol in my status bar instead of 3g a few times. It's been a while though...
Well from what i see thats not true.
Im on 1xRTT right now. The icon is a solid white.
Even if that was the case and it should grey out. That is completely deceiving. It should accurtly show it is on the 1x network.

sorry - who was this to? Also, I know there's a 1x symbol in the framework - it's got to be there for a reason, right?
OK I just checked the manual and it has a 1X icon. You're right.
Edit: The com.htc.resources.apk where sense signal icons are located contains the images for 1X so maybe it's something in the xml's that prevents the phone from either correctly notifying a 1X signal or bypassing the connection all together. HTC obviously intended for the phone to connect to 1X if they took the time to sensify the images. Strange.
Yes HTC intended for it but thats not the case. Has anyone on sprint successfully dropped to a 1x Connection ? Here is what I notice if im not forcing a 1x connection.
If it looses a 3G connection, it does not successfully drop to 1x. It just looses 3G all together then tries multiple times to go to 3G if it doesn't succeed you loose internet.
If you have a 1x prl it loads 1x but shows its a 3G connection wich is not true at all. This is disappointing.

ummm...yeah - like I said in my prev post, I've seen the 1x icon appear on my phone in parts of nj where I wasn't picking up 3g.
What ROM are you using ?
OK Im going to grab my friends Evo tonight that is on a sprint a force a 1x connection and see if his shows accurately or not.
I assume your custom PRL is forcing a 1X connection on sprint towers and not verizon or something? The phone may only show a drop to 1X if on sprint's network. If you are on verizon or cricket or something it probably wont indicate 1X.

I was either using stock, or an older version of baked snack.
Its not a custom PRL the one im using is a cricket prl. Made only for 1x network. It does not support EVDO.
Sprint has a few 1x PRL's only and I will load his phone with it and test it.
That doesn't make sense. The phone being on cricket or any other service would not make the phone report its on 3G all time. I flash a lot of phones to cricket. Like i said before this is a Sprint Rom issue. I loaded it with a incredible ROM and it successfully drops to 1x connection.
fachadick,
You might have been using baked snack rom.
Im checking tonight with the service on sprint.
So far its confirmed.
Two people with HTC EVO's on sprint.
One (Me) on with evo on cricket.
We forced all three EVOs to work on 1x connection only. All three of them are showing 3G icon but are only getting 1x speeds. This is very deceiving.

The reason I say it might not work on a PRL from another carrier is because when I am roaming I get a triangle above my reception, but the data icon remains 3G if I remember correctly. The actual data connection is only 1X because of roaming agreements, so what I am theorizing here is that the phone only changes to 1X when you are on an authentic sprint network and the connection drops to 1X. This is probably built into the rom, which is why it works for other phones, but not the EVO.
Because you are using a "roaming" PRL, I would think that the phone doesn't trigger the change to 1X icon just like actual roaming with a Sprint PRL. That's my hunch.
Yes i understand what you are saying, and yes that is plausible.
But doesn't explain why when we force the sprint ones they do not change to 1x ? I can force any other phone to 1x on the sprint network.

[Q] Dropping data connection

anyone experiencing data drops particularly when the phone is in weak 4G coverage? It acts like it cant switch between 4G and 3G. sometimes it might take 5 min or more before it will reconnect to data. the phone works fine when it is in a strong signal area. So far I have just experienced this behavior in low signal coverage.
Yesss! Experienced that yesterday. But came back on in 5 min. Usually fixed when u go to settings and switch from the lte to GSM and back to lte but haven't had trouble with it today

Yours is the first case I've seen where data drops altogether, most have just been going back to 3G too often.

I am having the no data issue as well! I leave my house (on wifi and supposedly 3G or 4G) and I want to start listening to music immediately in my car but I have no data connection once wifi is off. It can take over a minute or more to get a data connection! I was wondering if this had to do with LTE protocol negotiation, as this is my first 4G phone. However it seems way too slow and its very aggravating. When it does get data back, it is usually 4G not 3G. Toggling data mode on and off doesn't fix it. I have not yet tried toggling between CDMA and GSM.

does it only happen when you're leaving wifi and going to cell data?
My experience with data connection was spotty for the first couple days. Going from WiFi into 4G then 3G on the way to work required a reboot to pick up the 3G after I arrived.
I think I may have found my issue.
Settings -> More... -> Mobile Networks -> Network Mode
Was originally set to "Global". I've found that "LTE/CDMA" works better for me.
hope this helps some.

928i 4G not working, 3G intermittent and dropping calls - recently started occuring

this phone has started playing up, 4G wont connect at all and 3G is constantly changing between H and H+. Phone calls dropping and battery draining fast.
Have tried factory reset
flashing older Samsung firmware
Nothing is making a difference. Tried my SIM in another phone and it instantly connects to 4g.
This only started about two weeks ago.
Any one else have this issue? i'm in the uk on the 3 network.
UPDATE: it appears the 4G radio is faulty - setting it to 3g only solves the issues.
UPDATE : I'm so gutted that this phone 4g/3G is ****. Love the phone but loads of people and reviews suggesting 4g/3G issues with this phone and high number of call drops. I did a test today, I put my sim in an iPhone 6 and instantly connected to 4g and speed test was through the roof peaking at 38mb. Put the sim back into the s6 edge plus and only connects to 3G. But unable to browse the Internet. This confirms my fears that the 4g chipset/antenna are ****. In this phone. Which is a real shame as the phone is my favorite ever. Going to get an iPhone now. Connectivity is the most important thing and I can't be dealing with this crap from such an expensive phone. Shame on you Samsung.

I have the exact trouble as yours whichs about constantly changing between the H and H+. (4G is not matter, its new around here). When it turns on H, doesnt connect any site and application which need data connection. But H+ is doing normal. I bought an unlimited data package is provided for up limit 7.2Mbps. Dug something and saw that HSDPA(H) technology's up limit is 7.2 for our carrier. Then bought limited turbo data package(shows as up limit 43Mbps) but still changing H and H+ Thats not such for current device. It was in such an annoying situation since H+ available to connect. Tried to force use H+ but no luck. Sorry for long article and bad grammar. Just saying. Thanks.

Been doing a lot of research and it appears to me that this phone is crap at holding 4g/3G signals. I think this is a hardware/design fault. Most people won't release this until they test this on an iPhone in the same location and see the huge difference. Can't believe Samsung would release a huge pile of crap.

I don't have this problem mine is actually reverse. I have better signal and faster Internet than my Samsung s5

Starting to get annoyed with the O variant phone in the UK

It's all too frequently dropping 4G or LTE connection when on the move. It's showing a connection, good strength too, but no data connection working. Often needing an airplane mode toggle or reboot to get online again.
5G is disabled as I'm nowhere near a 5G area.
Anyone got any ideas? Different firmware or something?
I'm starting to regret moving away from the SD note 10 plus I had. That phone was rock solid.

I read that some people have issues with connection with some ISP providers. Try putting it on 3G and see if it works fine then. If it does then ISP has either sn issue with 4G network or phone needs a firmware fix to solve 4G connection issue if this isn't a hardware problem thought. Since for me it works fine here and my 4G shows all time and I even have 4G+ as status without an issue.
try disabling WiFi calling that helped in my case
Tried all that. Went into a town and it didn't again.. Had to force it onto 4g to get a connection.

Haven't had any issues myself, on giffgaff. Tried O2 briefly, it seemed okay too.

Give this app a try, might help fixing it to one band
https://play.google.com/store/apps/details?id=com.ray.samsungbandselection
Yes u have that thanks. It seems to be band switching that's the problem. Or is it possible my carrier has live but unused bands that the phone is locking into? So when I travel I find myself with a dead data connection?
