Please help to rerolve this lagging issue.... I have sony xperia X. I updated latest version patch, but after updation my phone is very slow and drain battery quickly. Please advice
This can happen after applying updates and may persist for only a couple of days, but if you think it lags more than that you can try to perform a software repair using Xperia Companion. This will do a clean installation of the latest firmware and will also wipe your internal memory. Don't forget to backup using Xperia Companion, but preferably without adding apps or settings to the backup.
