Find 7 indeed does not have yellow tint, it is just that the LCD colour temperature is slightly to the warm side but brightness is dimmer than Find 7A (the early batches in March/April).
Not sure if anyone posted this. You can adjust slightly by doing to the following.
1. Open Phone app (the dialer)
2. Press *#36446337# (basically means *#engineer#) to go into Engineer Mode
3. Go to Manual Test
4. Go to LCDgamma parameters
5. Tab on menu (the one left of home button) and choose the LCD parameters you want.
- Color-Null shift is by default
- reddish is towards warm and with a slight green (to my eyes)
- yellowish is towards the cooler one (the bluish type)
6. Once done, make sure you press the back button all the way back to the dialer screen (to ensure the settings is permanently set), so that you do not need to change again each time you reboot.
This is based on v1.2.6i firmware. No root required. Works for both Find 7/7A.
If you want to know a little more about the hardware, scroll to Other Information. You can see things like the main board, display panel, rear/front camera by which company, etc. Other settings I don't know and will not touch. Do it AYOR.
Enjoy. Good night!
