Invalid IMEI, serial number and model number - General Questions and Answers

I bought an S8+ from Craiglist a bit hasty and I think I was tricked. There were a few photos on the Craiglist and on one of them, there's a phone displaying both IMEI numbers (dual sim) and a box with a sticker and the same IMEI number. We met, I checked the phone quickly, everything works, phone looks as advertised, we're both in a hurry, I give the money, take the phone and we split. I took a photo of his driving licence and a car registration. 2 days later, I found a time to set it up and made a switch from my old Galaxy S5. Before inserting SIM card I type *#06# to check IMEI once again just to find it's completely different! And even worse, online services recognize it as an "invalid IMEI". I then checked serial number on IMEI.info and it sees the phone as Galaxy S5. Then I checked model number and it showes SM-G950, which should be a regular S8, not S8+. It's obvious someone has tampered with the IMEI numbers and system. Now, things complicate for me. I don't live in the USA, I flew back to Europe and I can't easily go to the police in US and try to find a person.
My questions:
Where do these wrong info come from? Is there anything I can do to reset it to the factory values? Is the IMEI number truly changed or just software change?
IMEI: 353456789104561 / 01 and 353456789104562 / 02
SN shown when typing *#06#: R28H33QX82H
SN shown settings>Routine management>status: 0123456789ABCDEF
Model number SM-G950
Thanks

Unfortunately, the phone is a copy of Samsung S8+, I realized it once I faced it to the original one. I bought it in Dallas, I have his driving licence and a car plates. Does it make any sense to contact the local police? Will they do anything about that?
Thanks

No there is nothing they can do as it is not a criminal matter. You would have to sue him personally. Which would never be worth it really.

Check this out in ATT Fuze

Hi att fuze owners,
Could you please compare IMEI number of your phone from Start>Settings>System>Device Information>Identity and compare it to the number printed on the back of the phone beneath the battery?
My Fuze has a 15-digit IMEI listed on the box and under the battery.
In the OS, it has the same first 15 digits, but then there are 2 additional digits listed at the end (for a total of 17 digits).
It seems strange to me...I had never previously done a digit-by-digit comparison between the phone and OS before.
i looked through my old devices and it seems that it's always like that where there are 2 extra digits.
My IMEI is the same on the box and in the Settings page.

S/N Not Matching on Android Phone

Hi all,
I have recently bought a dual sim phone and I noticed that, although the imei numbers on the box, in the phone and in the Android info match, the serial number doesn't.
On the box and inside the phone, under the battery, the number is the same, but when I read it in the Android phone info, there is a totally different number.
What does it mean? Have I been swindled?
Thank you,
A

S6 "lost" its IMEI

A colleague of mine bought an S6 from an ebay seller and it has been working fine for about 2 months, then the weekend before last for no apparent reason, the phone lost its IMEI.
The phone has never been rooted, and when he first got the phone we checked the phone with the "Phone Info *Samsung*" app which indicated that this was a genuine non-refurbed device.
The original IMEI started with 359800, but now it's reading 35(and a lot of zeroes)
Anyone have any idea how this happened and if it is recoverable?
Is it possible that this was a cloned device with a fake imei and somehow that has disappeared?
It just seems strange that the IMEI would go for what seems to be no reason at all

[Q] Cheap new phone won't connect to mobile network - dodgy IMEI?

my daughter bought a cheap phone from a well known website here in Australia.
It is dual sim, I think it's a knock-off of a more expensive phone, the model number shows "R11max"
Seeems that no sim card we try will work, they all say "mobile network not availablke" when I try to make a call, text messages won't send, etc.
When I check in About Phone> Status> IMEI information, both SIM slots have the same IMEI.
I'm guessing we got ripped off, with a dodgy phone that somebody has slapped a dodgy IMEI onto, cloned /duplicate IMEIs which have already been banned from the network or something?
Do you think my theory is correct or what else could be causing this problem?
It's not legit for both slots to have the same IMEI is it?
Regarding IMEI - this is normal. some phones with 2 SIMs can have 1 IMEI. If the phone can only have 1 SIM active at a time, then only 1 IMEI is required. Only the true dual-SIM devices, where both SIMs can be active at once, require 2 IMEIs.
You can check the status of an IMEI for lost/stolen etc here: http://www.lost.amta.org.au/IMEI
Some sites give you more info on your device based on IMEI: http://www.imei.info/
Not sure about the network issues, but I came across this random thread while searching. Seems the R11Max is one cheap nasty piece of junk, sorry to say. You'll struggle to install any apps on it, because there's literally not enough storage. Anyway, have a read of that if you get time: https://arstechnica.com/civis/viewtopic.php?f=9&t=1426197

SM-G930F has "weak" network

Hello,
A few months ago, I've bought a second hand Galaxy S7 from the UK (via eBay). I'm in Belgium, the phone was unlocked. I ran a few tests, the phone worked fine and I*installed LineageOS 16 (this one:*<https://forum.xda-developers.com/galaxy-s7/development/rom-lineageos-16-microg-t3921094>).
I've just notice a few weeks ago that the network was not as good as another SM-G930F (with the same ROM). In well-covered areas, it seems fine, but when moving (on a train…) or when in remote location with medium or bad reception, my phone lose all network.
I've tested it with two SIM cards (two different operators) and it's the same result.
I've also noticed that the IMEI and SN on the back cover of the phone are different from those in the system settings (and via *#06#). I asked the seller and he told me “We are sorry to hear that, it may was broken and we have change it with another origins back from another phone, the main number is the one in the settings.”
What could I do to try to improve the network connection?
Should I be worried about the IMEI/SN change?
Thanks!

The phone has obviously been re-built from different parts of S7's, the antenna may not be seated correctly or even damaged. The S7 is not designed to be taken apart by re-sellers.
IMEI, Yes it is illegal to change an IMEI number of any phone. You've been sold a dud phone.

Thank you for your reply. I guess I'll try to check the antenna. This issue aside, it kinda works well…
Is there a way to check IMEI numbers before buying a second hand phone? I've just searched online, but there's too many sites, most of them not free, and I don't know where to begin. Is it country restricted?

Is there a way to check IMEI numbers before buying a second hand phone? Yes there is a free network provider website in most countries to check it's valid and you can check on Samsung website. Don't pay any money to anyone! If an IMEI is blacklisted or reported stolen the phone will not register on any network.
Yours is working so is fine.
