Uncompromised phone with new wallet. Had Bitcoin moved but how

So I know what is going to be said my phone is compromised. But hear me out. So I won $1000 dollars worth of Bitcoin. Had it transfered to a brand new wallet. Didn’t look or back up the memonic phrase. Only created and transfered. And went to bed. Nobody knew I even won it. 8hrs later it’s moved to another new wallet, while I’m asleep. Phones not rooted. Has no malware that I’m aware of. Scanned with several trojan finders, anti-malware programs. Nothing found. The Bitcoin still sits in this wallet it was moved to. No friends, no business partners. I sleep with my phone, it was turned off actually and I have 6 pitbulls. Nobody had physical access to the phone. Next morning turn my phone on. 5 minutes before I do. It’s moved. I turned off the phone 1 minute after transaction is completed. It is an app wallet. And with all the security breach’s, I’m positive it’s not on my side. The app wallet says the same thing over and over. We can’t be hacked. Are devs are perfect. Bullshit. Everything is hackable one way or another. devs are human. And mistakes can and will be made. How can I track this transaction, get all the info possible and reverse this transaction? Support with the wallet refuses to even consider this. Says it’s my phone. The backup I never made. And even tho I powered off the phone it’s my fault, and there’s nothing they can do. That someone had to physically have my phone. Powered off? Immediately after transaction? Well noone physically had my phone, no one to have it. No business partners. Now it’s conomi wallet. This is the wallet address it’s sitting in. 1BppitPsoVtF3NmJRDvvfYKpEjMNU2G2Sp
