Since i bought my s20 ultra, i got only 1 update and my security patch are dated march 1. So now i am more considering other brands. Even i read that samsung released alot updates and fixes, i never got them. So sad. Feels like i paid for name not for good smartphone.
Are updates the only feature you value in your phone? The April 1st update is out, but there are many reasons why you might not have it yet. What is your carrier, model, country? Locked or unlocked? Using with original carrier or moved to another (if carrier branded)?
Samsung updates are known to be dated as OneUI is a heavily modified skin onto of Android, this has been the deal for years. Samsung has always been leading in the hardware department however their software updates have been lackluster. However the features that are in Samsungs software often are ahead of stock android, so you're not losing on much. This forum is for help though as has been said. I expect you'll receive more updates soon, do remember that with the current pandemic, a lot of service are running slower.
