How can you roll back / reboot Android 6.0.1 that was perfect for my needs completely. 7 is terrible If someone wants to know why I want to switch back to version 6.0.1 read my statement below.
Hello. Yesterday, an update of my Galaxy J7 2016 (J710FN) to Android 7 popped out. Earlier my phone hung several times for a year. And I didn't have any problems with it. At the moment, i.e. after yesterday's update, the phone has become inoperable. It freezes, it doesn't run smoothly, Wifi has moments when it doesn't work. Packet internet is extremely slow. I am not getting application notifications. The upper beam has become completely useless due to its hopeless appearance. The clock on the lock screen looks like **** I was only able to set the screen brightness adjustment bar to be on top, unfortunately, to press the "outside" button which is useful and intuitively placed in the previous version, unfortunately, but you already have to bother with entering the settings ... And what's funniest yesterday I lay down sleep and connected the phone to the original charger / cable and overnight it is about 6 hours charged a few percent ... which can even be seen in the screenshot
You need to download the odin and soft program to your phone, for example from https://www.sammobile.com/firmwares/ and follow the instructions of the software - uploading the software. The data you have on your phone will be deleted.
In truth, it won't change anything about the aesthetics of the new system, but you can try to hard reset the phone and maybe then the performance problems will solve.
I haven't been here a long time. After several attempts to upload a new software. I managed to upload soft, probably from the French distribution with that name J710FXXU3AQF8_J710FXEF3AQF1_J710FXXU3AQF4_HOME.tar.md5 using ODIN 3.0.4 (other versions could not cope because it bugs) The system has 99% returned to its previous state. The only difference I noticed is the inscription 4G instead of LTE above the range indicator.
