Last days I got OTA update to FW ver. WW-32.2050.2050.29

After that I instantly could observe the issues like below:

·       1) the battery is discharging much faster,

·       2) the WiFi connection goes OFF in 50% cases after screen goes off,

·       3) The camera anti-flicker option is no longer handling my light environment at home,

·       4) I observe few apps (Whatsapp, Loxone, 9gag, mydealz) hang up from time to time and need to be killed and started again to bring them into operation again

·       5) the fingerprint does not work stable like before,

·       6) the phone does not wake up instantly or not at all in 30% of cases when pushing the side button

The issues are annoying me terrible since about 1 week.

Which things I tried to solve the issues:

·       a) trying to use different battery modes,

·       b) clearing app's cache and in the end fully removing and installing them again,

·       c) removing fingerprints and adding them again

·       d) resetting the wifi/bluetooth settings

and because all of above has not helped:

·       e) I made hard reset 2 times already, once per phone settings, once via Recovery Mode


And still my problems remain unsolved!


I am getting crazy, because now I am fully disappoint how the phone works.

Until the mentioned FW update all was working really good, I was really happy with the phone and its performance as well with the battery life.


I really doubt, that there is a way to solve my described issues.

This is why I think the downgrade to previous FW ver. WW-32.2040.2040.23 is the only possible solution. I tried to do it, I have searched how to do it, but I could not find any FW package, which allows the downgrade procedure.


Can someone help me with the downgrade?
