**Equipment used:** I just bought a cheap Bluetooth handsfree from china: http://www.miniinthebox.com/mini-stereo-wireless-v3-0-headset_p1187467.html **Explanation:** This works perfect for me, and i don't notice any problems at all. The problem is that for people calling me, or i am calling hears them selves in an echo with about 1 sec lag. I cannot hear this echo at all, but for everyone i talk to with the handsfree set hears this echo. If i mute the mic, then the echo disappears. **My question is this:** Is it possible to remove echo by using any software or android setting? **I think that there should be two ways of doing this:** **1.** muting my mic while the other part talks. (nearly like an automatic walkie talkie) **2.** cancelling what is sent from the other part, and don't send the same sounds back to the other part again.

Phone: Samsung S7 SM-G930F Problems: 1) Person I am calling or that is calling me hears delayed playback of their own voice 2) When speakerphone is activated a very loud noise is heard from the other caller's speaker making it impossible for them to hear me speaking When I'm in a call (cellular service) and I activate speaker phone the other person can't hear me (I can hear the other person perfectly fine when on speaker phone). When I call (via regular cellular service) the people I call often report 'hearing an echo' in other words 'hearing themselves talk' , I have already changed providers which did not help. The 'echo' is always there from beginning till the end of the call from what I've heard. I have a Samsung s7 SM-G930F. Previously had android 8.0 installed (which was the OS that came with the phone originally. I recently installed a different ROM (Lineage OS 16) but this had no effect on the speaker phone problems. I tried starting the phone in safe mode as suggested in this video: https://www.youtube.com/watch?v=Z6qcYwyTl-w But this didn't have any effect on the problem (same 'echo' still there). Suggesting it might be a hardware problem (assuming what's being said in the video is correct) The following post suggests another possible cause: "Apparently there is some kind of rubber band around the microphone that keeps the sound in the same place" (source: https://us.community.samsung.com/t5/Galaxy-S-Phones/S7-Other-side-hear-echo-on-phone-call/m-p/119530#M7152) . I think this might also explain the 2nd problem (loud noise on other caller's side when speaker phone is activated). Does this seam probable to you? Voice recordings work fine. The 'echo' doesn't appear to be present for all people, I'm told it has approx 1.5 seconds delay (the other caller hears their voice back with approx 1.5seconds delay). When I start a call in whatsapp and talk to the other person they say they have no echo and can hear me just fine, if I activate speaker phone I can hear them properly but they say they have the echo again and there is a lot of background noise coming from their phone (sounds like 'some sort of electrical interference'), the 'echo' gets played back louder on their phone when I activate speaker phone, so loud that they cannot hear me talk. When I turn speaker phone off on whatsapp and continue talking the other caller says the echo persists for some time (maybe 8 seconds) after which they hear a 'tick' sound and the echo disappears (also the 'electrical interference' background noise disappears immediately as soon as I turn the speaker phone off). It happens regardless of how many 'bars' of connection I have. Could it be a broken microphone? Could it be an issue with my antenna/connection? What tests could I perform to track down the cause of the issue. i have tried with and without the case (I thought the case might have a negative effect since the s7's speaker and mic are right next to each other) Would love to hear your input Thank you very much for any suggestions!

I have local terminal access and ping command works when WiFi connected, but not when connected via cellular service. I get same results using ping within other apps. Can this be "fixed?" Phone is Verizon, brand Samsng J7 V, software build M1AJQ.J727VVRU2BSA1

I have recently installed Remix OS on my PC, and now it's like a craze. Nothing worked. I always think it was the problem with the touchscreen, because EVERY operating system I used on my PC, the mouse jumped everywhere. But on Remix OS, it isn't like that. The mouse didn't jumped. But I have a more serious problem. It won't accept any input that uses mouse, and I have to use the keyboard all the time. I found on the system the terminal, which I think can be used to turn off the touchscreen. Is there any way I can turn off the touchscreen using adb or echo?

I have a Galaxy S3 phone and a Galaxy Tab 4, both with the same issue. I'm using the Echo Lockscreen app (paid version) with a pattern unlock, which I'm happy with. I'm also using the built-in "Clock" on the phone and "Alarm" on the tab. When the alarm rings and I shut it off, the phone/tab is unlocked - so it skips the unlock security. Using the stock Samsung lock screen, the lock works and I have to unlock the phone normally. I'm not finding any settings either on the device or in the app - any ideas on how to fix this? I'd be willing to switch to a different alarm clock app, but I'd like to keep the lock screen unless there's something as good as this one. I can switch Echo to use my system unlock method instead of its own, but the user experience is kind of crappy there - you have to unlock then also swipe away Echo. If someone steals/finds my phone, I'd rather not have it unlock automatically for them if I don't remote-wipe it before 6am the next day. **EDIT** I'll be getting a Galaxy S6 in a few days to replace the S3, but I'd guess it will have the same issue there as well - but I don't know for sure.
