I recently bought a Galaxy M34 with 6000 mAh. Its battery endurance was awesome for the first week. Then I started playing around and I decided to set a custom font with the help of the app zFont 3: https://play.google.com/store/apps/details?id=com.htetznaing.zfont2&hl=en&gl=US
I used a normal font that I took from the windows directory on my PC. Since the day I set the custom font, battery life started to degrade to an extreme degree. From an average screen on time of 12 hours until I reached 20%, I got 9, all the time. And I was using the phone the same way and in the same places and circumstances. Also, the screen on time never went up from 9 during the following weeks. I ended up returning the phone but, what if zFont 3 could have a virus? The way it manages to set the fonts is strange, it will ask you to install a font made by the app by the title of Samsung Sans, that you don't know what it has inside, then upload a backup to the Samsung Cloud, then install another app made by this app with supposedly your custom font inside and nothing more, then restore the backup from Samsung Cloud... Some people have even said that after doing this they end up with a Settings keeps stopping error... This app seems to mess a lot with your phone. Could it possibly push viruses into your phone or corrupt your settings?
