Yeah I had that problem with older apps I tried before. Switched to downloading from
1-xbet-tanzania.com/download/ and it's been much more stable. The app loads fast and doesn't lag during live matches which is crucial for in-play betting. Make sure you have a decent internet connection though because that affects performance too. Some apps are just poorly optimized and will freeze regardless of your phone. The current app I use updates odds in real time without delays. Worth trying different apps until you find one that actually works smoothly during peak times
