I am having several problems with the stable 7.2.3.0 LIBRA, the battery runs out quickly, at a certain time of the day around 14.00 there are line and data access problems and leaves alone the timing even if it is enabled with WiFi . Compared to the 7.2.1.0 version it was only solved the problem of synchronization of email, which now works.
I wanted to know if I could do a downgrade to 7.1.6.0 doing just wipe & Dalvik cache.
