I would suggest a higher end phone such as the
- Samsung Galaxy s21 series of phone's.
- Samsung Galaxy s²² Ultra or s²² series of phone's.
- Samsung Note ²⁰ Ultra.
- Or wait to see what the Samsung Galaxy s²³ looks like.
- Maybe look for a phone that works with an sPen due to your student work as it may come in handy !
- The above isn't an exhausted list available by any means so do look at the Samsung Online Shop Site for more options that also lists their features and functions.
I'd suggest a higher end phone as you want to be able to perform tasks for your student work.
However some mid range phone's are powerful too. 👌
Samsung phones are typically released with various apps to help with such work.
It also depends on disposable income or what stage your at with your mobile contract if on pay monthly
i.e early upgrade or upgrade status if your on Pay Monthly.
Or if your taking out a new contract then the choice is yours.
Or buy sim free.
I'd suggest to check out YouTube reviews and look at tech blogs like sammobile.com as one example. There are many sites. Google Search is your friend 👍
Also visit a Samsung Experience Store and or Highstreet Shop that has working retail demo models on display to get hands on experience with.
Make a shortlist and slowly whittle them down until you reach two potential phone options.
We are always here to help discuss which potentials you've decided On.
I wish you all the best with your journey.
