Before it was my must have app, every feature was awesome, the connection rate was Ok, the adds were also acceptable and not annoying like in other free app. But latest update version destroyed everything. Xender app has become as aggressive as a virus, spamming the phone with adds even on the phones lock screen and always being active. I'm really sad to see this aggressive behaviour. I desided xender new version deleted my phone and try to get the old version working again. 4 stars because the app does an amazing job for filesharing and is easy to use. 5 stars again when the aggressive behaviour of the app will be changed. Best regards, a sad & disappointed user please try this app.
