Poco X3 NFC (surya), with V12.0.8.0.RJGEUXM of Xiaomi R Firmware, and Arrow-v11.0-surya-OFFICIAL-20210719-VANILLA.zip. I am using Arrow Recovery. (The latest TWRP is not working on my smartphone, I can't flash anything) For some unknown reason, my Poco X3 turns off by itself at night and restarts at the time of the alarm... The morning, I find it on the sim unlock screen. Any idea what causes this ? According to the battery data, it turns off during the night and does not restart until the morning to trigger the alarm clock. Is there a setting that causes this ? At night, I never turn it off, I put it in airplane mode. In the attached image, it was in airplane mode, it turned off (not sure why), and it turned back on to trigger the alarm ! I had this problem three times. Also, and maybe there is a link, very often when I press "turn off" the smartphone freezes and reboots. At night, however, I absolutely do not touch my smartphone. Thank you for your amazing work ! PS : If necessary, I have no problem doing a clean install, I have no important data. But I have already done it and some bugs persist. (Netflix glitch, smartphone freezes). Maybe I am doing something wrong during the installation?
