Re-Installing stock Samsung OS

[Rob1971]

Hi I am looking to buy an S9 and try /e/ OS, to eliminate an echo issue I have on my S7 on /e/ OS:

Issue with echo heard by call receivers on some Galaxy S7 devices

Issue details: Some Galaxy S7 users have complained of an echo at the call receiver’s end. The caller would not be aware of the issue unless the person on the other side of the call complains. Some of these devices were purchased from the Murena Store. Investigation: The development team did a detailed analysis of the issue and has arrived at the following conclusions. The issue is due to incompatibility between the hardware and the software which assists in the noise cancellation. This prob…

If I buy a regular S9, install /e/ OS, and I find have the ‘echo’ issue, how easy will it be to restore the phone to how I received it, to return it.

Thanks

to restore the phone to how I received it, to return it.

Once you install a Custom ROM or recovery to a Samsung a Warranty Void flag will appear on the Odin mode / Download mode screen.

You can see this on your existing Samsung.

• Warranty void: 0 is “original”
• Warranty void: 1 is “evidence of custom activity”

Thanks.

I would only look to return the phone if it had an echo on it with /e/ OS installed.

Can you see the Warranty Void 1 in /e/ OS ?, or would that appear only in the Samsung OS.

Odin is a flash utility ? would a vendor run that on receipt of a returned phone, guess thats a question only they can answer. Unless they did, presume it would not be apparent that there had been ‘evidence of custom activity’ … makes one sound less than perfect !

Well yes, as I said, “will appear on the Odin mode / Download mode screen”.

No utility is required ! As you imply we do not know how thorough the supplier’s return process might be, but any (experienced) reseller would know that it is prudent to check the Download mode screen on a Samsung before sending a refund, I would think !

But of course you could offer to buy it on condition you experienced no echo on a custom ROM.

Thats a great link and info, thank you.

Time to buy another phone (and be aware of the echo before I install /e/OS.

/e/ OS on my S7 has so far has proved to be a winner, depsite the echo, but time has come …
