I'm not sure if there is a fix for this. Update the PRL and your profile. If the problem is still occurring it may just be a problem with the service itself.

There are multiple threads on this here in this section.. go into settings, click on mobile network, and change CDMA/LTE to just CDMA and see if that helps, I have had the same issue but haven't had the chance to test this out yet

3G CDMA disconnecting during high data download

Hi,
I have been facing some strange issues from the day i got my photon,
My 3G CDMA (EVDO) works fine in normal scenario (with normal web page viewing) but when ever i try to do large file download / try watching youtube with HD video the EVDO gets disconnected and i think the radio re-starts after around 1-2 mins and the data connection is up again.
Same thing happens if i try using speedtest (may be that also tries to send big chunk of data to test BW) and when i try download big files of more than around 5 MB in Google play.
When this data disconnection happens in my EVDO signal bar only upload arrow is being shown and no download.
This issue is persistant in all the Rom's i tried (have faced with Stock/CM7/MUI/CNA/CM9).
Using the photon in CDMA with Reliance in India.
Pl help me to get the issue resolved
Might just be an issue with your service provider.
I wish I could watch youtube in HD lol

I don't think its a problem with service provider as the issue is not present in my friends mobile (Samsung)
Dumb question but, did you make sure that you dont have data saver enabled. I had it enabled from Sprint and had an issue like that. Its under settings--> battery & data manager--> data saver

Some one pl help
If this has happened since day one, the n you should flash stock on it and turn it in for a replacement because it sounds like it might be a hardware issue. Its obviously not a software issue since it happens with so many variations of roms.

If you're sure that when flashing the other romz you appropriately wiped data, system, cache, and dalvik I'm inclined to agree with fugitive. I would flash the latest sbf and see if the problem persists. If its still there, get it traded for a replacement as your issue isn't normal.

That could just be an issue with their network in india then, but just to make sure, are you using gsm or cdma networks, because it could be a gsm issue. I would think cm9 would be your best option seeing as how they have more gsm support

This might sound crazy but I had the same issue. Mine was the otterbox commuter case was sticking to the power button a bit and powering off my phone and rebooting. Did you put a new case or something on it?
Sent from my EVO using xda app-developers app
Dont use a case. Updated to 1.7 hopefully it stops
Sent from my EVO using xda premium
i kno its a pain in the a$$ but sometimes running an ruu back to stock and then rerooting the phone helps... worst case.. i did that when my evo 3d kept acting up like that.. and it helped...
Happened again today. Super annoying. If it happens again im going to sprint and demanding a new one

Try wiping everything including factory reset then reflash rom.
I did do that. Idk what the problem could be

Mine does this as well. I talked to HTC and they said if you don't LTE in your area, Sprint LTE that is but have Verizon LTE, your phone may be trying to latch on to the Verizon LTE, and since it can't quite connect it attempt to push more power to the LTE antenna to get it to connect, in doing so, it eventually pushes it pass a threshold and causes the phone to reboot. Apparently the issues seems to be popular in areas where there is no Sprint LTE and other LTE available. Sounds like a software issue on HTC's end, that will hopefully get fixed.
For now, you can try and go a *#*#4636#*#* and change your network to CDMA Only or EVDO Only and see if that keeps it from rebooting. (when you change to CDMA only, make a call right away otherwise you might not get incoming calls or texts)
I dont make many calls but the few calls i usually do make or receive are important and i would hate having to switch that. U think it will work if i turn off mobile network in the drop down settings???
Im in los angeles btw and i think verizon lte is live here

Hi this worked for me. I'm stock and experienced connection issues with my wifi...sitting 2 feet from the router!!! Never had any problems connecting anything via wifi b4.
Go to settings>>wifi>>menu>>advanced. in the advanced section there is a radio button to enable Best Wi-Fi performance. Once activated I had no more connection problems.
Hope this helps.
Not sure if this might help but I changed WiFi to 2.4 GHz and like above best WiFi per. So far good

I did this and it worked for me briefly but then reverted to "authenticating" and then telling me it is the wrong access key for the network. I don't understand why it's doing this but at least for me it seems to be a 1.22 based problem as everything I've run with the prior firmware has been fine....

Your problem is different. Mine was dropping WiFi signal and then self reconnecting. Not anymore though. Your problem I have not came across. Have u tired running the ruu and reset your router?

I've reset the router multiple time and even gave my EVO a static ip to see if that would work. I guess I'll ruu and see if that will help. It's weird though.

Wifi issue with Evo LTE

I have encountered a rather odd issue and am at a loss.
My download rate is atrocious (approx. 250–300 kbits) but my upload speed is about 5 mbits. I have isolated it to my EVO which I just activated and started using on my Wifi. Obviously the bandwidth is there based on the upload but no matter what I try; resetting the modem and router, isn't working.
Stock evo lte on most recent firmware.
Any help you have to offer is greatly appreciated.
Sent from my EVO using xda premium
Have you checked your download speed with another device, just to make sure it's your phone and not something else, like the router/network?

Yes. Both my lappy and tv are chugging along nicely via Wifi

click Menu then advanced
click WI-FI frequency band

2.4Ghz only
try that. It might be trying to bounce between 5Ghz and 2.4Ghz
Still crap speeds. Ugh. May be my router and phone just aren't meant to be friends.
Sent from my EVO using xda premium
Changed my router from auto to G only.. Finally getting the 15Mbits per second I'm paying for.
It would appear to be a software issue, hopefully one of the many that is fixed if we ever get JB.
Thanks to all those who provided feedback on this matter

4G LTE issues

I have a question about my 4G issue. The only time i can get 4G is when I select 4G only in the command settings, but then i don't have voice services. Is there a fix or a know issue about this issue im having? This happens with any rom i flash.:crying:

4G on the EVO is garbage. My S4 is picking up 4G in areas my EVO never has and with great speeds in areas the EVO had picked up 4G. Not sure about your issue though. Update PRL and Profile?

Weird thing that I have noticed is,
I have perfect LTE (25MBps up) when I run Stock Android 4.2. CyanogeMod 10.1
Any Sense Rom I run it has no LTE. When I select CDMA/LTE it won't connect to Data at all. When I select CDMA it will connect to 3G.
I hate it and have never found a fix for it. So I am stuck on 10.1 with not a lot of updates. Which is fine, but I like to switch back to Sense everyone once in a while and when I do I am forced to use only 3G.

i know that's what I have heard as well. My phone is weird, but it runs perfectly on stock Android so I can't complain too much!
Mine connects to 4g lte without issue as long as I'm running meanbean or stock with goodies. On several other rom's I had problems connecting. Not sure why.

No, if I remember correctly you're picking up sprint lte, it just thinks it's verizon or whatever carrier you're roaming on.
Also, OP, have you tried switching to another phone, then switching back? I know that sounds weird but my brother was having data issues on his virgin mobile phone and that's how he fixed the issue lol

No. Your 2G network which controls voice is roaming. However your phone has an established 4G network connection. Sort of like being on wifi and roaming. Your calls go through the 2G network while the data is being handled by your wifi/4G. Those signal bars are strictly for your 2G connection. 3G and 4G have their own connection which is not viewable unless you dig into ## settings from dial pad. Sprint don't have any 4G roaming agreements with any other carrier.
