So recently I made a factory reset to my LG L70, because the apps weren't working properly. Also I deleted everything from my SD card. And after the factory reset and everything, my battery is draining pretty fast because of the mediaserver (uses about 30% of the battery) and the phone doesn't recognize not even the standard ringtones, and the gallery won't show the pictures I downloaded. I put some music and photos on the SD card, some of them will apear in the gallery, some of them not. I deleted again everything on the sd card, and the problem persists. I rebooted my phone for like 20 times during all the processes and the battery still drains fast and some of the media files won't be recognized. I am starting to deeply regret the factory reset. Please, any help would be welcome, thank you!
