This is what happens when phones are smarter than their owners.
Looking at some of the comments in the Play store it is no wonder people are uninstalling the app. They don't understand how it works at a pretty basic level. I genuinely feel sorry for whoever it is who has to post replies to comments such as these:
"Bluetooth is not needed for anything in the app however if you don't enable the app does not work." - A typical 1 star "review" from someone who seems to think the app runs on fairy dust and moon-beams.
"Sorry I can’t make head nor tail of the NHS COVID-19 app. I don’t understand apps. I’ve tried to download the app and all get is advice on ordering prescriptions." - That's because you've opened a different NHS app which to be fair does look very similar.
"I do not consent to surveillance." - Says someone who's never read a EULA in their life.
"Good but uses battery while on blue tooth" - Waking it up every 5 mins to check the battery level (or your Twitter feed) probably isn't helping.
"Dont install, it's a waste of time. Covid is done and over with." - Tell that to friends and relatives of the 4.06 MILLION people who have died from it so far.
"Annoying as hell that it constantly demands Bluetooth to be turned on, I don't need reminding 5 times a day" - Perhaps a good slapping would work.
And my current favourite:
"I have deleted this since finding out you can fake it to get a isolation alert all you have to do is tick one of the boxes of symptoms I tried it and got the alert straight away twice, I do not have any of the symptoms, so how many people will be saying they have an alert when not true" - Thanks to you, probably everyone you've been in close contact with recently.
If it is your job to respond to people like this then you are one of the unsung NHS heroes. I could not do your job.
