After the update, the phone feels just as good. That is to say, I didn’t have any errors and that’s how I continue. The new features that they indicate (e.g. selection of icons in the menu) I already had before updating. They should review that the changes they make are real, it is not serious. Otherwise, happy with the phone.
Not so much with the lack of communication from the company. I’m not asking for a big camera update for tomorrow, but it would be nice to inform your buyers whether or not there are intentions to fix such a nonsense camera that we currently have.
I didn’t have any heating or battery problems. I have never had. I would like to know what type of use you make of the device and what settings and applications you install. I have social networks, some photo editing apps, etc. Typical and zero problems. See if there are any that consume excessive battery power. Honestly, I would try a factory reset in your case or take it for repair if you really have these problems during several updates.
For my part, I recommend the update.
