I totally get what you’re asking — I had the same doubts when I first tried using the app. What helped me was this detailed review:
https://dailysports.net/en-ng/bookmakers/1xbet/mobile-app/. It’s a legit guide tailored for Nigerian users, and it breaks everything down — like minimum phone requirements, where to safely download the app (especially since it’s not on the Play Store), and how to complete registration smoothly through the app itself. I used it to install 1xBet on my Android device, and it worked perfectly. They also include a guide for iPhone users, which my brother used with no problems. The registration part is explained clearly too, so no confusion there. I’d definitely recommend starting there if you want to avoid any headaches. From my personal experience, it saved me time and made the whole process smooth.
