I used an app called LTE Discovery to see the active connection/Band, the service "Crash" issue was happening when the phone was connected to B66 4G+ network and not on regular 4G or even other 4G+ bands, did some google search and found an app called Network Signal Guru to lock the phone out of it, so now i still happen to have 4G+ connectivity with other bands, B5, B7, it does not connect to B66 anymore and i dont see any service crashing now after that, the downside its that you need root for Network Signal Guru app to work.Thanks, how did you go about blocking bands, and finding out which ones to do so?
My provider just deployed 5G on some areas and im able to connect to that as well after this mod.
