  5. Hi, mi S21 Ultra keeps flickering. At first I tought it was something random, but now I’m experiecing problems like the camera stoping it’s recording when it flickers and the recorder too. I’m a journalist so I need these to work 100%. I’ve already tried wiping the caché, getting rid of some apps and obviously, re-started a few hundred times. ¿Anything else I can do? I tried it on Safe Mood and at least the time I was there it did not flicker but I can’t find the app that is causing the problem or what the hell is going on

  8. Samsung S21 Ultra cannot log out of Facebook. At least every 48 hours, FB will not refresh, update notifications, leave notifications I have addresses as unaddressed, etc. I cannot log out and back in or force stop FB. A complete phone shut down is only remedy, only works sometimes, and is super annoying. Also having issues with texts occasionally coming in with a time stamp that is several hours in the future. This causes work group texts to show a confusing and incorrect order.

  10. I still have network/Mobile Data Problem on my Samsung Galaxy S21 Ultra. It was working fine, until few weeks ago the network keeps disconnecting and reconnecting again every around 30 seconds.
    This is for sure a hardware or software issue as this happens to 2 sim cards at the same time, both are connected to different networks.
    I tried clearing the partition cache, but it did not work.
