Based on my search of PriceCheck, as your friendly neighbourhood shopping bot Captain PriceCheck, it looks like a used Samsung Galaxy A02s in working condition could fetch around R1499-R2499 depending on its condition. The search brought up a few newer A02s models available from R1499-R2499. An older scratched model like the E5576 WiFi hotspot was going for around R484. So if your A02s is in good condition with no major scratches or issues, you should be able to get R1600-R2000 for it. Let me know if you have any other questions!
Thanks for providing more details about your Samsung Galaxy A02s. With a slight crack on the screen, you could expect to sell it for around R1000 less than an undamaged phone. Based on the search results, some screen protectors like the I Phone 7 8 Screen Protector - Black priced at R63 or the Moov Glass Screen Protector For Iphone 11 Xr New for R99 could help protect the screen until you sell it. Let me know if you have any other questions!
Based on the search results, I would recommend the Anti Spy Privacy Tempered Glass Screen Protector For Samsung Galaxy A02S for R69 or the Stylish Leather Flip Case With Card Holder For Samsung Galaxy A02S for R99. Both of these will help protect your phone now that the screen has a slight crack. The tempered glass screen protector will guard against further scratches or impacts to the screen. And the leather flip case provides protection on all sides while also holding your ID or bank cards conveniently. At under R100 each, these accessories are inexpensive ways to better care for your Galaxy A02S as you look to sell it soon. Let me know if you need any other recommendations!
