Deep_Jangra , Jul 17, 2019 : my oneplus6 recently started laging too much .the camera app of the device wont open for long and then the whole phone would stop working and nothing works for couple of minutes . when i open other apps it suddenly gets closed on its own and apps like snapchat would start to stop responding or freezes or open very slowly . i have reset my device twice but nothing works i have also tried to uninstall the apps and to install them again but it does not work . this started after i updated my device to the new security OTA. update .. can anyone suggest something useful??
