It could be helpful if ppl would post which models they have and whether or not they have issues such as hue, white balance, etc. Info should include: Model: (XXGB, 4G/wifi only) Serial number: (you can provide only the first 5 digits from the left, if you don't want to share the full numer; this will enable decoding factory and manufacturing date) How many days do you have it working: (to determine if it is something that goes away or not). Issue: (yellow hue / white balance; etc). ------- * Before filling your details please check that "auto brightness" turned off; brightness value set to: MAX. * If you only have partial details from the above, please do share what you do have/want. * It would sure be useful if you respond when your model works perfectly OK. We hear about a lot of complaints but have no idea about the percentage of the defective models. In case I missed something or anyone wants to add anything please be my guest. I hope we can learn something out of this, please co-operate!
