Green Line on Videos shared to WhatsApp by updated Samsung Galaxy S21 Ultra 5G

Just yesterday I had written and shared a post on "My Samsung Galaxy S21 Ultra 5G" and boasted of its many features. I also mentioned its latest updating to android 12 and said that let us see whether all bugs previous to this update are being addressed or not.

But before getting into details a new bug has been noticed when sharing videos on WhatsApp, as can be seen in the screen shot capture above. I shared a video and the recipient asked that was my phone camera Ok as the video showed a green vertical line to its left. Alarmed, I surfed the net and there were many similar complaints. It is unclear whether the bug is due to Android 12 update or with WhatsApp!!

I joined a Samsung community and shared my concern, where already a large number complains had already been registered. However, thanks to the Samsung, as I got an e-mail tell me:
Re: Green line on WhatsApp Video shares
It's an issue with the video resolution during compression. If you switch from FHD to UHD video the green line goes away when sending videos on WhatsApp. 
But when sharing on WhatsApp, I don't find any option of UHD. There is only option of converting FHD to UHD except actual size. Has anyone solved the mystery as yet? If so please share in comment box

My Samsung Galaxy S21 Ultra 5G

I have been a Samsung Galaxy user for about two decades. For sometime, I switched over to OnePlus 5T as was gifted to my son. OnePlus was also a good gadgets and a found some different features from my old Samsung phone. But this year, I got a surprised gift of Samsung Galaxy S21 Ultra 5G from my son who is always on the look out for some new technology intensive device for me. And here I am using the many features of my new phone which just got updated to Android 12.

The phone just launched on 29th January 2021 is laced with many strong features, some of which I am mentioning as under: 
  • It has a big 5000 mAH lithium battery that gives me long hours of usage without recharging.
  • It has 16GB RAM Exynos 2100 for fast processing
  • The screen is 6.8" 1440x3200 pixels - and due to its Dynamic AMOLED 2X, 120Hz, HDR10+, 1500 nits (peak) display, it is treat watching HD quality movies with vivid and vibrant crystal clear videos and images
  • The phone has quad cameras that include 
  • 108 MP, f/1.8, 24mm (wide), 1/1.33", 0.8µm, PDAF, Laser AF, OIS
  • 10 MP, f/4.9, 240mm (periscope telephoto), 1/3.24", 1.22µm, dual pixel PDAF, OIS, 10x optical zoom
  • 10 MP, f/2.4, 72mm (telephoto), 1/3.24", 1.22µm, dual pixel PDAF, OIS, 3x optical zoom
  • 12 MP, f/2.2, 13mm (ultrawide), 1/2.55", 1.4µm, dual pixel PDAF, Super Steady video
  • Its video quality is superb with 8K@24fps, 4K@30/60fps, 1080p@30/60/240fps, 720p@960fps, HDR10+, stereo sound rec., gyro-EIS
  • The phone comes with a fast USB Type-C 3.2, USB On-The-Go which charges the phone real super fast
  • There are much more to it which can be viewed here.

People are really curious about three S21s. The Galaxy S21 has a 6.2-inch screen, the Galaxy S21 Plus a 6.7-inch screen and the Galaxy S21 Ultra a 6.8-inch screen. This is the main difference between the three panels, but not the only thing you should consider. However the ability for the display to alter this rate is greater on the S21 Ultra.

A number of bugs and added features were addressed in a very recent updates starting from 22-24 November which I am still trying to figure out. One of the major issues have been with the 120 Hz mode, specifically that the screen drops down to 60 Hz as soon as the user lifts their finger rather than, say, when the scrolling animation is done. Hopefully it is taken care of.

Cellphone app will now alert if someone within close vicinity of Covid-19 affected person

In order to stay away from a potential Covid-19 carrier, apps are being developed  that would warn if one is close to a affected person.

Apps to use Bluetooth signals to track phones the user comes into contact with and  now people will be alerted if they may have been exposed to someone with Covid-19. However, the app will only work if a person using the app who has been tested positive for Covid-19 and has uploaded his data to a public database. If there's a match, the person will receive a message indicating when and where they might have been exposed, along with guidance as to whether they should just watch for symptoms, seek testing, or self-quarantine.

Apple and Google are joining forces to develop technology where smartphones can warn users that they may potentially be exposed to coronavirus. 

However, the implementation has raised concerns over potential beaches of privacy, though the tech giants insist that the data will be anonymous and that 'privacy, transparency and consent are of utmost importance'. There's also the likelihood of a high number of false positives due to the imprecise nature of Bluetooth itself.
