There are so many lags and bugs after Android 10 update in Nokia 8.1 that disappointed every one including me. Every one expecting update for stabilizing the Android 10 or rollback option to Android 9. But till that time you can remove some bugs / lags by removing cache memory from each and every individual app from settings. Pl. note I am not talking about cache memory removal of device that normally we do in routine. I am talking of cache memory removal from each and every app from setting.
Select setting, select app & notification, select see all apps, select any app, select storage & cache, select clear cache.
Do this turn by turn in all app. That's all. Pl. note only clear cache memory don't clear storage memory of app.
Try it out and remove some bugs and lags. Pl. post me after doing the same.
Hope for the best!
