Samsung M30s September security update

[Anonymous]

As we got September security update i clean flashed it using odin and here is my review of it... 

1. Restarts :

    No, i don't have any restart issues as of now.

2. Hotspot :

     Still good no issues in connecting my laptop and pc.

3. Display :

     No display or brightness issues

4. Charging : 

     It is taking 2hrs 40-50min in cable charging (0-100%). No heating issues while charging.

5. Network issues :

     Yup.. still there. Same airtel and jio giving min 16mbps in other devices at home whereas i stuck at in kb and max 4mbps (rarely).

6. Heating : 

    Funny think i didn't have heating while gaming but when using Instagram and discord i felt mobile is getting warm.. mobile gets too hot when using data ofcource due to network issues.  

7. Battery backup :

     Here my usage is like 3hrs normal gaming (Wcc3 includes online 1hr), Insta, WhatsApp, discord and other streaming like YT, Hotstar etc this is the SoT i got 👇👇

After update battery needs calibration so i charged in switchoff mode thats the reason you are not seeing charging stats in AccuBattery.

Deep sleep overnight drain is still same 3-4% .. before july update it was 1-2% .

8. Connectivity :

    As i said i don't have issues in hotspot but i used to have WiFi and BT issues.. wifi reception is slow all devices getting 50mbps BB speed where i get around 20-30mbps only. Still same. But BT was getting disconnected frequently while connected to headsets and buds. This BT issue fixed now. Watched a movie for 3hrs and not a once BT disconnected. 

9. DRM issues :

    Seems DRM issues fixed now for Netflix and hotstar. 

Only prime app has issues now i contacted them and 4 out of 5 executives said next update of prime app will fix it. Hope it will.

10. Device care : 

      Idk if its a bug or a glitch on 6th oct i played wcc3 for 2hrs you can see it here 👇👇

But the same app is not shown in device care 👇👇

11. Camera :

       I don't see any improvements or any new issues in camera.

Conclusion:

No major issues you can update without any worries.. 🙂🙂

These are my observations do mention in comments if i miss anything 🤗🤗

odin flash means ofcource data loss.. you have to backup before or ask them to keep data intact.. in service center they do 2 methods erasing data and without erasing data partition. but you have to ask them for this. if not they simply erase data too.

i feel nearly same as of you
except battery ( i love the battery when device was on Android 9 🙄) but after every update its getting worst.

obviously.. optimization in pie was best.. in pie i used to get 12hrs SoT with 60% . now see how it reduced..

phone is overheating while charging after september update. Before update it is ok, but compared to then now it is over heating.

once try clearing cache partition and reset device care. also turn off fast charging for few days.
