Its the worst device i have ever used it.
Since i have purchased Samsung galaxy s22 ultra its full of bugs and issues. Battery drain so fast despite of trunning off everything which does not make any sense if i have to turn off everything i should be using Nokia 3310.
Bluetooth issue is so bad it does not connect to earbuds or car kit whenever any call comes or you make any call until unless you select it manually on keypaid.
Worst customer service no one there to help.
Vpn connectivity is really bad i have premium vpn which works perfectly on my all other devices Huawei and apple but on Samsung it doesn't work specially using whatsapp call.
Sorry about the issues you are facing. I am not facing any issues with the device in which you mentioned regarding Bluetooth and battery drain. Battery of the device takes nearly 2 weeks or so to adapt and then should last a good amount of hours. 🙈
