S21 fe exynos march security update

[au795]

I wouldn't recommend you to update the march security patch for galaxy s21 fe exynos version as i am facing some issues which were not present before updating my phone

1. I am not getting proper 4g and 5g speed 

2. System has become laggy, phone always gets stuck after opening whatsapp 

3. Overall performance seems to be reduced as even for opening samsung members application i had to wait for nearly one min, untill it was loading the application 

4. Gallery app is showing wierd bug, while deleting a photo(captured by the phone's camera)it shows that the file's size is 1.41 gb😂😂

Pls do share your experience also if u are facing same issues and pls suggest solutions

1. 4G can't comment, but 5G hasn't deteriorated
2. WhatsApp had a peculiar bug of notifying" backup ongoing " randomly
3. Haven't noticed the same
4. Can you specify this bug? As deleting from My Files or from Gallery? & where does it show 1.4GB when you hit details or in the recycle bin?

Feb update was wonky, esp after some days
March hasn't been weird yet... touchwood

Ss from gallery app
Actual size is 90kb but while deleting the photo it is showing 1.25 gb

File size isn't 1.25GB. Your recycle bin has 1.25GB of files. Do check

[au795]

Cleared recycle bin of both gallery and files app still showing 200mb size of a photo
