Is there any bugs or battery drain issue?

Do I need to update to OneUi-5 to use 5G on Galaxy S20-FE5G? 

Galaxy tab S6-lite (2022)Can any one tell me how I can avail this back to school offer on this tablet.. what are the terms and conditions and how many days are left for me to get this offer Thanks for answer 

My first flagship phone is this S20-FE5G..I loved the camera most and performance is upto mark till now...one of the best from samsung Hopefully they don't discontinue this FE series here some photograph i have taken 

You can see it in MY JIO recharge section Tell me if you have tried it ... I'm not in a 5G area so yeah 
