What says on browserleaks.com/ip ? It says "generic tunnel or VPN"? As @Bers666, it can be solved by configuring the right MTU value.

If you don't have direct access to the proxy configuration, ask your proxy provider to change the MTU value as per your need.
I here if I change it to TCP mode it would resolve is that true

TCP/UDP is something else.
Usage TypeCable/DSL / Residential
I think it's very difficult to help someone when professionals ask you questions about your problem, but you consistently ignore every single one.
You haven't answered any of the questions that some people here have asked you... Actually, no one should be asking such questions; you should have already provided that relevant information yourself.

Check the MTU.
Make sure the mobile proxy’s passive OS matches the PC where you use OpenVPN.
If you use Windows, set the proxy’s passive OS to Windows, or it will be easily detected.
Use an anti-detect browser.
Finally, your mobile proxy provider might simply have a poor configuration or bad service.

if OpenVPN + a “mobile” IP still flags as a VPN it’s usually ASN/reverse-DNS/reputation or leaks, not the VPN client itself.
get a dedicated ISP IP (not a shared VPN pool), disable WebRTC, use clean DNS, and run checks on ipinfo.io; if ASN or rDNS points to a hosting/VPN provider it will keep getting flagged.

Which carrier are you using? I did some testing on my own Android phone and noticed the link type showed as OpenVPN, even without any VPN or proxy running. I don’t think that alone affects much, since this is a stock device with a US carrier SIM being used normally in the US.

I totally agree with this one from Bers666:
"I am detected as VPN" and other anomalies
The issue is:
- you buy a proxy or a VPN and want to hide the fact of using a proxy or a VPN
- you browse to a popular IP checker to get that info
- they show you are behind a VPN
- you claim the VPN or the proxy you bought is of a low quality
Is it true? Let’s explain.
First, let’s explain how they detect that a VPN is used. The answer is MTU, a special parameter of TCP session that shows size of a single IP packet. For Fiber/DSL it’s normally 1500. For mobile networks, it varies a lot. It can be from 1380 to 1460. It depends on the internal technologies of a mobile network .
So they detect the MTU, what’s next? Then they find a match using publicly available databases of typical cases (MTU and corresponding Link Type which can be VPN, PPPoE, Ethernet, Mobile etc. From what I know, many use p0f3 or similar databases.
OK, assume a mobile proxy has a totally valid mobile MTU 1460. Check the DB, this MTU has assigned with a label generic tunnel or VPN :
label = generic tunnel or VPN
sig = 1460
And then the checker wrongly assumes you are using a VPN, because of the MTU. The same applies for all MTU values marked as belonging to VPN.

Websites can detect VPNs using IP reputation, traffic patterns, or DNS leaks — even if your IP looks clean.
