I am hopping between U1 XAA and U TMB often. I like the TMB better for quality of calls and the only thing that runs me nuts us the horrific startup jingle on the TMobile versions. Once upon a time there has been an app called 'Silent boot' that worked it's magic, but it is an old apk and it does not work on Android 10 ( sometimes it does, most of the time it doesn't. Keep reminded SD US phones are bootloader locked and can't be rooted.
On normal days , COVID-19 aside, I turn my phone off on flights ( the only times I can rest is the 2-3 hours at 35,000 feet. Then landing is a nightmare noisy startup jingle, combined with all the following messeges coming in. I ALWAYS forget to put my phone on silent before turning it off ... then putting a finger in the speaker to muffle it..
I searched for quite some time, could not find a solution. Obviously the other option is not to turn phone off and keep it on airplane mode, but I found those twice a day 'off' time is a life saving on my poor battery. I normally on two flights per day.. and driving rural areas kill the battery dead very easy.
Any solution ? TIA..
