M21 ONE UI 3.0 problems

[Sanket24]

After One UI 3.0 update there are some problems

1) Ram management in 4GB ram version less than 800MB ram is available for user.

2) Battery drain is high.

3) Performance is low after update.

4) Sometimes device lags while scrolling.

5) No Carrier Aggregation even though requesting many times to Samsung even processor also supports it. So internet speed is low it reaches to about 70Mbps but in other devices it reaches above 100Mbps.

6) Poor WiFi strength

7) Camera autofocus is very slow to focus on object and for every shot it shows that "This shot might be blurry".

8. It shows a black screen while opening apps.

9) No Screen recorder in M21 but according to google android 11 should have screen recording option.

10) No Samsung Dex.

11) Charging speed is very less it requires 3hrs to fully charge even though it has 15W fast charging.

12) There is lot of heating of mobile and charger while charging.

Real main concerns for me:
1. No LTE only mode for 2nd SIM.
2. No VoLTE on Vi operator network, which was enabled for other Samsung models via software update (only Jio & Airtel have VoLTE on M21 for now).
3. No LTE Carrier Aggregation support, even when chip supports it.
4. No Good Lock application in India. I wish Samsung made this app available for India.

For VoLTE on Vi Sim, call customer care and request or send ACTVOLTE to 12345. Vi has deactivated by default after recent upgrade.

Thanks! called Customer Care, they activated VoLTE on Vi instantly. Works now.

Guys who are facing VoLTE issues on Vi network try this. They only activate when you call them for this Request.

Faced all of the 👆 adding 3 more:

1) Micro SD card (SanDisk made, class 10) suddenly shows as 'corrupted' - been using it since I first bought this mobile,
2) Youtube and other websites containing embedded video links, don't update thumbnails properly,
3) The new 'Bedtime mode' doesn't auto disable after expiration of time period, hence I'm often stuck with a grey screen (wind down screen) in the middle of the day.

.. seriously I think the Android 10 based UI 2.5 was much cooler, if there is an option to rollback later on, will do so.

Edit: In the mean time, if anybody solves the problem of painfully slow internet, pl. do share🙏
