Echo Bug Fix For All ROMs - OnePlus 2 Q&A, Help & Troubleshooting

So Guys ,
I have managed to fix the Echo Bug during calls some people have for all or some ROMs ....
well I can say its not specific ROM issue , either its baseband( software ) or sim carrier issue ! SO after intense testing with various different ROMs and sims all around world , I came to conclusion that 900 MHz frequency band i.e.. LTE network is causing Echo problem.
setting network mode to LTE in settings , for some carriers it gives this bug. Well for Some users its not the problem because carriers have dual band frequency set For Example : 900/1800 or 2100 MHz for me ! 900 MHz frequency can be for 2G/3G/4G , but as per my research maximum carriers have it for 3G/4G only . In India Airtel users are affected the most .
So coming up to Fixing up the bug , you guys can try forcing your sim to use any frequency other than 900 MHz , which is bad and not advisable because forcing to use one frequency will give you network drops and unstable network ( carriers go dual frequency to avoid this ) —---
I am not giving you this method but there is a easy method for all this to avoid !!!!!!
JUST CHANGE THE NETWORK MODE FROM LTE /3G /4G TO 2G AND TRY CALLING.
ALSO IF IT STILL GIVES ECHO , SWAP SIM SLOTS...
ALSO SOME PEOPLE IF STILL HAVE ECHO PROBLEM, THEN DID YOU HAVE SAME PROBLEM ON OOS ? IF NO THEN FLASH OOS AND THEN CUSTOM ROM OF YOUR LIKING - IT WILL FLASH THE LATEST FRAMEWORK.

Will try this method, will keep the thread posted. :good:
Thanks in advance.
EDIT: It worked for me, thanks bro!

Solved it, much appreciated.

fixed echo bug for me..thanks

The bug that I can hear myself only when using headphones is not related to this right? Just asking for completeness, as maybe this is another bug (mixer paths or something, dont really know lol)

Seems have solved it for me too, thanks a lot!

Yeah this bug is only about other people hearing their voice when talking to you AFAIK.

What's the underlying problem though? Is it only Nougat ROMs use the 900MHz frequency because CM13 is fine?

Please read the post again ! I already mentioned that its not ROM or carrier or band specific. Many people have problems on only N ROMs while others on all MM,N,OOS ROMs .... So still its in search mode ...

I only have it with Nougat Roms, no other Roms.
Don't really want to stop using 4g/LTE kind of defeats the object of a smart phone

I can only help with this now ! Surely if its a ROM issue then fix will come soon !

more information
It may be related to noise cancellation thing. People only complain to me when I am doing calls on car speakers through an aux cable. And this only happens in custom roms but not on OOS. Tested and reproducible 100 percent times. Latest OOS 3.6.0 with multiboot.

noob question

Is there any ROM or Hotfix or Fix or hack that will fix the lack of 3G support in the USA?
If so, can you point me in the right direction?
Please help.
Thank you.
i dunno whats the problem with 3g in usa... just my guess isnt it cell phone from europe which antenas use other frequency for 3g so it cant be fixed via software?
HTC claims that it can be fixed with a hotfix or something of that nature.
I have searched and searched the forums, I don't see anything of the sort.
Maybe I'm looking in the wrong place?

depends what phone you have and what network you are on.
phones for different regions have different radio hardware (not to be confused with the radio rom) and add to that different networks in the states use different frequencies.
flashing different radio roms WILL NOT change the hardware frequencies.
where is the phone from, and what network are you on?(not that I know anything about what frequencies go where, but someone will!)
Thank you samsamuel!
I purchased the phone from overseas (overseas being Europe).
I just sent it in for repair, but hope to have it back soon.
And hopefully with a fix to the 3G.
The problem is that the frequencies are different here in the USA than in Europe.
I know what the problem is, I'm just wondering if there is a tweak or hack to make it work in the USA.

ok. i know its not right to post it here. but please someone help ?

ok i seriously need some help. MODs please delete this if you feel like it. but i really want to know the answer for this since i posted it in the OT but no one replied.
my problem is signal issue with the EVO roms. specially from Mdeejay EVO roms
i downloaded the cayanogen rom and i have no problem with the signal " specially if i use it in 2G connection. its almost all the time full bars. while on 3g it sometimes varies between 2, 3 or full.
however, with Mdeejay eVo Sense v. 1.6 Revolution" and the other "warm evo" rom the he made. i do have the signal problem .
it sometimes show to me no bars at all just dots. even tho, if i call, or someone call, it goes through ...i think lol
it keeps on playing with the bars.
whats up with that? i am using a Tmobile version of the phone. " no i am not in US but i wanted extra ram/rom
i have been told that the HD Euro version has better signal. is that bs ?
anyway please please please someone help me with my question about the signal. its killing me. i love this rom so much i want to keep it. even the wallpapers are ****ing amazing. but this signal bar thing is driving me crazy
Honestly man i can't help you! I have signal issues also in all Android roms! I don't think Euro HD2 has a better signal!!! At least mine doesn't!
I feel so bad when i see an old nokia with a full signal and mine is 1 bar or none! I tried radio 2.12, 2.14, and 2.15 all the same and signal fluctuates a lot!
But i should tell you this: I like your nickname a lot!
for startes, have you tried flashing a different radio?

i might be an idiot if i answer this honestly but so be it. i didnt really flash the system. my friend did it for me . he told me its the best and fastest rom available for HD2 to froyo " built in andriom app to boot also "
all i do is just change the andriod roms by changing the folder on SD card and it does the rest lol.

i see your from lebanon ? keefek 7abiby
anyway. actually if you install the cayanogen rom. and switch the network signal to 2G only. it never drops below 3 bars in my case. which is good for me " i dont use 3G at all. and never planing to. i have wifi all around me "
I have the same problem with m-deejay builds.
The connection keeps dropping. Try using a darkstone build. Works fine for me.

I've tried to solve it by using darkstone's kernel but this does not work as well.
Others have this problem as well if you search in m-deejay's threads. I think you should try solving your problem there

ok i downloaded a program called no signal bar. from the market place.
it basically notify you when your phone is out of coverage.
and it works very well. so now. if i get a no signal bar from the rom, my signal notifier tell me that the phone is didnt lost signal. i try to make a call and it goes through. its accurate.
so i am happy for now. at least i am not afaird if losing signals when i see the fake bars from the rom playing .
i even tried to call my self when the signal no bars while the program " no signal bar"tells me i still have coverage. and it went through . i am happy panda... for now till i get a better fix for this
3G does not work when the bars are not displayed.
You can see this in the phone info application when you type *#*#4636#*#*

1- for some reason this number doesnt work for me. i am using Tmobile HD2 and the Evo Rom . might have anything to do with it ?
2- i really dont care about 3g. i just dont want the signal bar to keep showing there is no signal with its 4 dots crap signal when there is in fact a very good signal.
its like how the iphone 4 used to display signal that is not true.
are we the only 2 here who have this problem ? lol might be defective phones? lol
you can install the program called NETWORK from App store and basically change the setting to GSM (PRL) from that program

I don't think there is anything wrong with the phone.

i have tried around 3 builds so far or 4.
the only builds that has perfect signal bar to me is Cayanogen Builds " where in the setting there is an option called " Use only 2G networks " and have that checked.
any other version " specially if its build based on EVO ? " has a problem for me.
i am surprised not many are talking about this really.

NAND HD2 CoreDroid HD V1.6 ANDROID 2.2.1
RADIO: 15.40.50.07U_2.12.50.02_2
NETWORK: ERA *POLAND*
Signal Strenght: -89dBm 14 asu UMTS
I can loose singnal for about 30 minutes and it wont find anything. Then obviously i get 0 dBm. I have had the newest radio but i have changed to that to see if it solves the problem, but it hasnt. So im kindly asking You guys for help and Your opinions.
Thanks
Try if switching to 2G networks only in the settings solves your problem, this did the trick for me.
I only switch it off for fast 3G downloading, solves the missed call issues for me too.

For me when I was in Poland radio 2.14 or 2.15 solved the problem.
I am now using 2.14, I can see that you are using 2.12 I would change that to be honest and install other radio, just experiment a little and see which one is best for you

True but i'm unsure if its a network related problem or android because i flashed so many roms with different radio's always experiencing the same data conection drop problem when 3G is on.
So i just flashed back to the stock nexus build to stay.
I wish i could use the full potential of my device too...
(The menu to switch on only 2G network is only available on stock android rom, not on sense roms etc as they use their own menu styles)

Im now definitely sure that its not a hardware related problem as i tried 4 different EU HD2's and they all had the same problem after flashing android.
Now it's only to find out if it's a radio - android compatibility problem or just a flaw in android itself.
Ok,, now again for the 10th time , i started over from task29 , up to installing radio 2.15.50.14,, then boyppc v25 rom,,, and i guess this worked for me, i still have the connection dropping but less often than it used to be. it happens maybe once a day.
isn't there a developer who can help us find out what is the problem and develop a solution for us???

[Q&A] Dialer Echo Problem

Hey there Guys,
I have a really annoying Problem with my phone. When someone is calling me and talks nearly everyone tells that they hear a echo of themselve. I had this issue in the 2 4.4.4 Roms Form Danvh and now on the cm12 from netanalyzer. Is there a way to solve it?

Hi ,
Is the microphone cover?? if so uncover it , try it also without the phone back cover
Try to clean the microphone
Disable noise cancellation
Try and select under network the different bands available ( wcdma , 2G , 4G) to see if it is band related...
Cover oft no change. Clean isnt nessesary cause my phone got repaired had a hard crash. Where do i disable the cancelling in cm12? And isnt the cellular netwerk disabled during call?

Hi,
That it got repaired does not mean it has been cleaned...
do not know where it is in CM , on TW is in settings / my device/sound / call
during a call , unless you are using viber, skype or something like that you have to use your carrier network m there are different bands like wcdma , GSM......( mobile networks)
Was the sound in your phone working correctly before the "hard crash" repair?
Before the crash everything were fine. The complete screen module and some Sensor were replaced. The network and cancelling i try today. (Germany a BI different time)

[HELP] Jio 4g. Horrible Connection.

The data connection on my phone goes away after every few mins. It's very unstable. Also all of a sudden there's no VOLTE. I've tried all APN methods. I was previously on Mokee, and the problem started. I went back to miui, the problem was solved for the evening. But it started again.
If anyone has any solution. Please help. I cant even call using 4gVoice app. I want a permanent solution .
All help is appreciated. Thanks in Advance!
It's jio's problem
Hopefully will get resolved till march

The sim worked fine on k6 power.
I solved it by going back to miui and then flashing mokee.
Yet, it's surprising that it happens so randomly.
Probably something to do with default APN.

Even I'm facing the same problem with my Redmi 3s prime. It happened with resurrection remix rom and I flashed miui again. But didn't work. I tried different methods, but none worked. One of my friend said that jio by default takes band 5 for better coverage which trades-off with connection speed(low internet speed). One way is, to switch the band from 5 to 3 or 40, which might improve speed. This can be done in something called "service mode" in the phone. He had LG G3 and used some secret key in phone dialler to access service mode. That key however didn't work with Redmi 3s prime. I'm still searching for one.

Though it's more about VOLTE, it's not working. Even if it does work with a certain rom, it goes away after a few reboots.
FYI: I don't have fluctuating connection anymore.
Though I really wish that there was a proper solution for VOLTE

Thanks for the reply.
Though, for now, the problem is solved.
I'm on the latest lineage OS, and have hardly faced signal drops. Volte too seems to be working fine now.
Miui seems to lock our bands at 800mhz which hinders the net speed, switching to 3g/2g in low network areas, to maximize network coverage.
That can be tackled, if you use an app called 'network signal guru' , to lock the bands to a higher frequency, for preference to Internet. Requires root though.
Hope that helps you.
