I have a 9800 pro since February this year. The phone is great, the battery lasts a lot, the infrared camera works great. The only problem I had was with the proximity sensor in the beginning until I figured out how to calibrate it. To this day, however, the phone comes with the firmware I bought it...

If I install the update and a problem occurs ... for example, as my colleagues run out of battery, what can I do then?! .... can I go back to the old firmware version in any way?

I show pictures of the current firmware and the upgrade that comes out, but I do not dare to install.

The device has the firmware with which I bought it in early February. I dare not update it, although it constantly reminds me, precisely because everything works perfectly and I'm afraid there will be problems. The cable is charged in about 2 - 2.5 hours, and the battery heats up. To keep the rubber...

When I use the phone seriously, the battery lasts 2-3 days. At the most serious load I have achieved - 2 days. When I have a lot of work, and I do not have time to use it seriously, it lasts up to 10 days. In fact, the battery is one of the things I enjoy most about this phone :) http://alfa.kachi-s...

Okay, but please tell me if the update is tested. Keeps the 9800 pro stable and hassle-free after the upgrade. And I'm afraid to update because I have no experience with blackview, and I'm happy with the phone at the moment.

Let anyone who installed the update share their experiences. Is the 9800 pro stable after the upgrade?

Hello!

I can't find a way to lock autofocus when I shoot! On all the phones I had before the 9800pro, this was done by tapping the screen (pointing the focus) and holding the finger to lock the focus. This is extremely important, and I do not find a way here. Is there one?
