Update: New PWM video coming up    • Thank you, Xiaomi! No More OLED PWM H...  

This is not the typical car photography videos that I share online but rather a topic that not many people talk about.

I decided to make this video because many people like me suffer from headaches and migraines because of pulse width modulation (PWM) & the new OLED displays. The only difference is I know what is causing it.

Storytime. A few years ago, I was diagnosed with a terrible migraine. It crept in progressively & I reached a point where I couldn't drive, dizzy and out of balance. I visited many doctors and was given many medications to control the pain!

Now if you are wondering what the symptoms were, it was:
Pain behind the eye and behind the nose, mainly to the right side of my face, felt like a sinus infection
Light sensitivity
Felt like I had a fever, without the fever
Dizzy & out of balance
Couldn't look at monitors and mobile screens

Being me, I never settled for this, I had to know what is causing the migraines to get my active life back. I have looked everywhere…. until I stumbled upon    / karinnelson   video where she was describing my symptoms!

I have also found this post on Reddit   / massive_eyestrain_from_huawei_mate_20_x  , and back in the days, I was using the Huawei Mate 20...

I know what you are thinking... It's only affecting a small percentage of people & it won't affect you. Well, you are wrong! I used the mate 20 for two years before my migraines started... which means you can build up that intolerance over time. I don't know if this means permanent damage but listen to this.

I recently bought the New Samsung galaxy s21 ULTRA... that was a mouthful. I fully charged the phone and was excited setting it up, I even played a few rounds of clash royal & then I went to bed... with a slight headache!

The following day I woke up with a TERRIBLE headache, more of a migraine that lasted few days... I quickly realised the New Samsung caused this and sold it the next day.

My goto phone was the One Plus 8, which I bought a couple of years ago. It had a DC dimming option, and I was very happy because I found a good flagship device with that feature... But, ironically, they removed the DC dimming option with the latest update.

The following is a question to all smartphone brands out there ... WHY? If you could ease our pain with a simple optional software fix, why not include it?
