More little feedback on the telco reception.

I was in my carpark just now. Signal switched to 3G with only 1 bar. Previous Huawei P20 Pro still 4G with 2 to 3 bars, accessing internet not an issue. Granted I know Huawei phone has better signal than my previous Sony, I wonder if Samsung signal really that off? I guess folks with good area coverage would not face this problem.
One thing I like to seek Samsung guru's help, when there are missed message, there's no led indicator permanently on for S21. Internet says S20 uses edge lighting. I tried the only edge lighting setting I could find. The lighting only lasts for a while when message comes in.

How do I have a permanent light indicator to indicate there's pending message, reminder, tasks, etc? Notification indicator while the screen is off.

Thanks.

Battery life is good , can easily hit 6 - 7 hours of SOT on my S21 , but it's only been 2 days having the phone.

Signal is noticeably weaker compare to my OnePlus 8 pro , in the same area with the s21 I would have slightly weaker signal . Especially in underground parking . I'm on Celcom though

Thanks for the feedback bro. I had the Note 10+ for a bit and the weak signal strength drove me to sell the phone off in less than a month, so I wanna make sure it's not the case for the S21 series  since I've not used any other Exynos powered phone since then

Then again, with the MCO and working from home, I suppose signal strength isn't as critical these days

Try to put in aeroplane mode when you are sleeping. Monitor the next morning.

Exynos is infamous for weak network modem, making it keeps hunting for signal real hard. I had S7E, S8, S10, and S10E. All same symptom, unless I was staying at my hometown which had very strong signal and 100% on mobile network because no WiFi. It drained even lesser than my rented house with WiFi but has very weak mobile signal. I had since suspect it could be the modem.

Having said that, the other possibility is the bloated ROM of Samsung. But that's another story (software).
