    Default [Question] iPhone 5S freeze/lag/stutter when unlocking the iDevice.

    Hi, So i've been having this problem for almost two weeks now and i have no idea what i installed or changed on my tweaks i haven't installed any app or somewhat.

    By the way the lag occurs (I think) after using a lot of apps like twitter/reddit app/ or messenger at first 10 minutes unlocking locking the phone is fine but after hours or say for example i put my phone on idle for an hour or two next time i unlock the screen wont turn on immediately it will be delayed for 3 seconds or even 4 for worse. Then when i enter my passcode or touchid before i go to the home screen there's a delay for 2-3 seconds.

    Things that i have done to troubleshoot the problem:
    Removed passcode/touchID
    Removed recently installed app
    Removed tweaks that i think i installed recently
    Background app refresh, siri, handoff disabled

    All of that didn't work i only fix this problem by respring even clearing ram doesn't remove the lag only respring and reboot.

    iPhone 5s
    iOS 9.3.3

    I don't really know what's the issue or if this can fix it, but I'd try updating iOS using iTunes. iTunes reinstalls iOS from scratch when doing an update.
