Xiaomi REDMI NOTE 12 8+128GB DS 4G ICE BLUE OEM

I have had the phone for a year and a half. The battery life is really good and can survive a whole day of intense use without charging. I have had some problems though.Apps are closed very aggressively when you switch to another app. So swapping between a banking app, notebook and website is impossible. The browser will need to refresh, login again etc.I have also had persistent problems with contactless payments. The Google Wallet software will complain that the device is not secure and refuse to make a payment.Also, widgets in the OS just don't work. They do not get updated by the apps. Play and pause buttons for audio apps just stop working or have a long delay. And anything running in the background might not work. I have had alarm apps and email stop working until you restart.The sense I get is that the OS is very focused on reducing power and breaks things to achieve that. And maybe there is not enough RAM.
