Samsung Galaxy S II: Why do callers hear an echo during phone calls?

Sun, 08 Feb 2026 04:19:32 -0700

Hi!

Everyone who calls me says they can hear a bad echo of their voice as they speak, but everything sounds normal on my end.

I looked on some forums and some users blame the phone case for the echo. I took the case off and the echo didn't go away. Other users have tried sending their phone in for repairs and/or complete a factory reset with no luck. Is there anything else I can try?

Thanks!

Wendy

Samsung Galaxy S II: Water damaged phone, turns on but screen is black

Tue, 23 Dec 2025 18:17:46 -0700

Just recently, I dropped my phone in water, panicked and took battery and such out and dried the pieces and placed them in rice. I took it out and found out that my phone can turn on, receive notifications and all, but my screen won't turn on and remains black. I went to Sprint store, told me that they do not look at water-damaged phones... What are my options? The phone minus the screen is working perfectly and i would hate to buy a new phone.

Sun, 24 Nov 2024 18:11:20 -0700

I've had this phone for many years and I've gone back to it to fix it many times but never managed to do so

So basically this phone has a changing problem sometimes it did others it didn't charge and after a while it stop charging completely i thought buying a new replacement charging port will do the trick i bought one and still nothing no charge

I was thinking it might be the battery but if it was the battery wouldn't it stop charging in the first place because when i moved the Cable a bit it was charging but i have no idea

Samsung Galaxy S II: I can't take apart my Galaxy S2. Circuitboard is stuck!

Sun, 06 Dec 2020 04:46:32 -0700

I just got a second-hand Galaxy S II and am disassembling it to clean the insides of any dust and apply new thermal paste. I followed a few video guides on Youtube and they made it seem easy but…

Samsung Galaxy S II Teardown

I’m currently stuck at Step 3 of this guide because as I pry the plastic back panel off, I find a part of the circuit board that is directly below the audio jack port is stuck to the panel and slightly bends as I try to further pry it off so I stopped and don’t want to risk risk damaging it without any further guidance.

Here is a link to a photograph of the problem I’m having.

An help please?
