I recently purchased Xperia ZR, and it came with stock Android 4.1.2.
It notified me of updates sequentially to 4.2.2, 4.3 and then 4.4.2.
I installed all the system updates as well as the updates for Album, Walkman, etc.
Only after all the updates did I notice that the thumbnails in Album, Contacts or the contact pictures on notifications are distorted.
But this is completely random, one image might be distorted at a time, but appear clear other times. I have not seen this issue with full images, but due to the randomness I cannot be sure.
Since I didn't spend much time on the phone prior to updates, I'm unsure when this problem was introduced or if it was there since the beginning.
I have attached snapshots showing the issue in Album and in Contacts.
Please suggest what to do.
