As Samsung rolled out latest security OTA update for Samsung M30s, should I install it on my device myself or get it installed from Samsung service center ? As getting it installed from service center erases all the data, so which option is safe ? & Is it worth installing?

Depends on you. Installing update yourself is safe most of the times. Recharge your phone fully and don't restart your phone during update. Also the network speed should be ok during time of update. Updating at night or early morning is better.
