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.

Samsung Galaxy S II: Why is my Samsung Galaxy S II stuck in Airplane mode?

Mon, 28 Sep 2015 06:27:26 -0700

My Galalaxy S II phone is stuck in offline (flight) modus. The offline (flight) modus can not be switched off:

At start-up phone is already in flight modus (airplane symbol)

When pressing power button and choosing "offline-modus" the "offline modus becomes grey" and can not be reversed again. Phone is alwas in flight modus

Removing battery with device on for several minutes did not help.

Also removing battery with phone off does not help.

WLAN works fine but no calls can be placed (neither incoming nor outgoing) and no data up- or downloading over mobile phone network is possible

Anyone has a great idea how to fix this?

Samsung Galaxy S II: My samsung gt-i9100 turned dead and will not turn back on!

Tue, 03 Feb 2015 14:55:52 -0700

I had my phone on the charger while sleeping for a duration of almost 8 hours like ive done for the past 4 years ive had my samsung. However ive had my hotspot option active aswell. I woke up and opened my phone normally and was surfing my facebook account searching through friends walls and posts, when suddenly my phone turned black. i thought it was a glitch i tried to press the homepage over and over, it didnt work. i pressed the on/off button and it didnt even show any sign of power no light no screen no nothing. i removed the battery for over a minute plugged it in and still nothing. i removed the battery and plugged the phone in the charger still no sign of anything not even the charging icon. i changed cables still nothing. i surfed the net for answers and tried several tips. i pressed the volum button up and down. i pressed the home button with the on/off button with the volume and still i cant even get the reboot factory reset option. i tried connecting it to the laptop and still no sign as if my phone was just a toy :( . Please all im asking is for a way to access my info on the phone and my whatsaap messages and contact lists. please awaiting your reply and suggestions.

Many Thanks
