screen dims and brightens automatically

[Phone雲]

My xperia C3 has below problem and can't solve by Customer Service:
When web page, forum, letters that contains high colour(red / yellow words , pictures) the screen dim automatically. When scroll it out of the screen, it becomes bright again. It hurts my eyes and annoy me so much.
CS said it can't be solved, please wait for version update, maybe.........
Can I only wait, wait and wait? Xperia C3 is **bleep**.
- auto detect envoirmental function is off
- no screen saver
- no 3rd party software installed, just rec'd from CS
- android 4.4.2, software version 19.2.A.0391

@hellohelloworld : Hi..its almost solved..thanks a lot. Since i bought this mobile, I hav been looking forward a solution for this, but still i found on very few pages getting dim n bright, should increase to 63 to any other figure? 

[hellohelloworld]

I refer to this dim and bright problem. I suppose Sony would fix it on lollipop update, but it is not. Recently, I've tried to adjust the white balance setting, I found that some setting can improve the problem a lot, such as (63,63,63).

I should not say this setting can totally solved the problem. What we should do now is sharing the webpages that got dim and bright, and then figure out the best setting together. I am just a simple user, but I spend a lot of time trying to make my c3 better.

I hope this problem can be solved. Please share anything that we can improve our C3 such as the front camera. Before Sony releasing another update, it is one of the thing we can do in this forum. 

Thanks!

Hi..after a visit of many web pages n playstore i figure out 117-117-117 is d best count to remove almost 99.9% dim n bright. U can also check in playstore at editor choice..scroll down may b 2nd app called EQ being with skyblue.

Hi..after a lollipop update issue with front camera i hav tried many camera apps n found finally " A better camera" app [ Avbl in play store] this app works fine in c3 dual. 4:3 size pics good in this, once u choose 16:9 again d pics r dark. For this size better take it n sony camera by changing setting to manul n hdr on..somehow better alternative until d new update release from Sony.

[hellohelloworld]

Thanks! I am happy to hear your suggestion. How about the flash light of front cam? If it works，I will update to lollipop again. At this moment，I keep using the Kikat build .391 firmware. It takes time to upgrade and downgrade again.

Ya.. Flash is working fine with this app. But b4 u update install this app in kitkat n check it, if u convince, go ahead..

[hellohelloworld]

Hello, I have tried "a better camer" and "camera fv-5" on lollipop, both work fine on front cam 4:3 including the flash light. As you said,16:9 got dark image. Thanks for your clear explaination. I think it is the best temporary solution for c3 lollipop user at this moment.

Camera fv 5 seems to b no front cam? While im using with kitkat i used camera fv 5 and cinema fv5[ video rec] both apps fulfilled my requirement.

[hellohelloworld]

[ravi_p7]
