So many budget phone just like oneplusNord 4 now get andriod 15 but samsung till now not update any device expect s25 models.samsung didn't push oneui 7 for older device for selling s25 series.
I share screenshot how s 20 fe 4g support lte plus (carrier aggregation) but my s20 fe 5g dose not support. I use jio sim on both handsets You can check .
All samsung s20 fe 5g user please send mail to samsung ceo. Please mention carrier aggregation issue in mail.https://contactus.samsung.com/customer/contactus/formmail/mail/MailQuestionGeneralNew.jsp?siteId=592&PROD_ID=G303850
