The new update 64.0.A.5.71 claims to have fixed overheating and focus issues on the telephoto lense.
In this video I am putting it to the test to see if it really is fixed.
This video is doing also an overheating test this is why it is a bit longer. Also if you want to see more overheating tests please see the Sony Xperia playlist on my channel where I post more test videos.
What is your experience with the 1 IV
What should Sony do to fix overheating?
