    Hi,

    I am new here so not too sure which category to post under.
    I recently purchased an iPhone SE which works fine however when I use my fingerprint to unlock the phone the top left hand corner were the main page comes into focus always stutters a little. Its extremely annoying and I am not too sure if it is a software bug or the actual fingerprint sensor feeding erratic information to iOS...? I am running iOS 9.3.5. When the phone was first purchased it was running 9.3.3 and had no issues during the unlock. It's only after I flashed the phone with iOS 9.3.5 from two different sources and restored my backup that this started happening.. I'm coming up to the end of my 14 day try period and not too sure if I should take the phone back or not?

    Thanks!

    It was purchased from the apple store close by.. so returning it would be easy.
    If I remember prior to restoring my backup and and just after upgrading it to 9.3.5 from 9.3.3 it was working fine. Could it be that the backup taken from my old 6 that was being applied to the SE doesn't quite "fit" perfectly?
    The really strange thing is after about a day of usage without switching the phone off, the issue seems to go away until the next restart.

    Could it be a hardware fault...?

    Reset all settings, restore again, or (probably easiest) update to iOS 10.

    I'll give iOS 10 a try and report my findings! Thanks guys!

    Where is generally a safe place to download IPSW files?

    By the way, I was just wondering..
    Does everytime you restore another iOS version or generally just restore to a previous state damage your phone?
    Like long term damage to the internals? It generally heats up when doing those operations...?

    Restores are CPU intensive operations and it is expected that your phone get possibly "warm".

    Any general damage done (to flash chips) after many attempts at updates and restored since I've done it about 10 times...? I've still got about 5 days left on the return..

    The memory in most phone will last 10+ years so wear is not a real factor.

    Ok, I've finally worked it out..! Basically when you name a folder with a '/' you may get that stutter. I had a folder called News / Finance (when I created two separate folders and put the appropriate apps in them the phone no longer stutters when you unlock it). Now, I also noticed the time blink a few times after unlocking the device and after a little googling the time issue seems to be because a reminder or message is on the notification screen. I cleared the notifications on the screen and the time issue disappeared too..!

    Lessons learnt are:
    1) dont use / during folder names
    2) pending notifications (like a reminder on screen) may cause the time to flash


    Just out of interest, do you see this to be a software bug or a hardware issue, like do you get the same issues...?
