System stability and performance
During installation, the Nothing Phone (3a) Lite may consume more battery power and become warmer than usual. Nothing advises that this is temporary and that both power consumption and performance will return to normal once the process is complete.
The rollout of Nothing OS B4.1-261029-1756 is being done in stages, so it may take some time to reach all users. To check if the update is available for you, go to Settings > System > System update.
