After I was really happy with my Samsung S5230 two and a half years, it has been found that the touchscreen suddenly stopped working. After I had this repair in a relevant specialty store, I was not a little surprised to see how many similar phones were there also repaired using the same vulnerability. Research on the Internet have finally convinced me that the touch screen of this phone is technically not mature or was in the time of production. The successor S5260 Star II no longer uses the technology of the S5230. Each owner and each owner of such mobile phones (S5230) can only be advised if possible to save all contacts on the SIM or to use an extra memory card; the durability and usability of this phone is ultimately a gamble.
