Thanks for being with Samsung and for sharing your feedback. Sir, Samsung offers you the best value on the product released. Updates are rolling out by time to time for the devices, However it totally depends on the availability and compatibility of the update with the devices. \We would also like to offer some troubleshooting steps to overcome the issues: 1 Adjust the brightness of the device then check it (Setting-->Display-->Brightness) 2 "Disable the " Show Screen Updates" option in developer options or completely disable the Developer options."((Setting-->Developer options(If its available & highlighted)-->Show Screen Updates)) 3 Check third party application if downloaded recently, Post which issue occurred. Then, check in Safe Mode. 4 If in Safe mode problem is still existing we advise you to create the Data back up & Factory Reset the device. 5 Periodic Software Update through FOTA , SMART SWITCH or Smart Tool is intended to resolve the issue as well. Be sure to hit ♡ when you find an answer that works for you.
