extracting png file from app

I have extracted some png files from one app. I cannot open them using android gallery neither on windows.

Can you help understanding what is really this file and what should be changed in order to view it?

here are the first few lines of the HEX code of the png.

67 3e 65 09 38 a1 25 50 42 d3 14 be c8 23 b1 3d
06 e2 4e 38 f7 c0 36 58 7d 06 2b 1c af 10 6b 4c
bd 1f dd ae 7a 9d 68 8c 89 26 22 7a ea ca 66 b8
99 80 9e a4 48 1b 1b a3 22 96 b6 08 2f 93 c3 c1
57 12 d1 8f 31 22 02 7c ac 29 32 5a d3 cb 48 67
c5 d1 09 9d 82 2a 58 d6 3d 41 47 7a fa de c7 88

Edit:The file is named with png extension. I extracted them from data/data folder. Tried to open it on windows. The above code is when opening it with HEX editot
