How to fix optimising app issue in any android phone.
Guys this is my tutorial video on How to fix boot screen stuck at optimising app issue on any android phone.
If this FIX didn’t work for you then try flashing your Android phone for which watch this video of mine:-https://youtu.be/N62HnrbG51U
Guys the idea behind removing the battery is to turn off your phone and boot it up again so that we can press the keys together and get into the bootloader or recovery mode. Now If your phone has an inbuilt battery then don’t worry just try to power off
your phone in any way and if you can’t then let it be as it is and let the battery drain out completely after which plug in your phone and do the procedure mentioned in the video.

NOTE: -Guys this is the fix for optimizing app issue on any android phone.Now as far as what I know about this issue, this issue is caused due to many reasons such as a corrupt file in your boot sector, Due to some update patch from the manufacturer, Due to some bug in the running version of the system software or maybe your phone got brick. And whenever this issue occurs your phone just goes into a boot loop and optimizing app message is displayed which never really completes or starts your phone. Now what I am going to show you is how to recover your phone from this state and bring it back to normal via a factory reset from outside your phone’s system since you wouldn’t have any access to your system while this issue happens. Guys, now I can assure you that your phone will be recovered from the boot loop but I can’t promise you that this won’t happen again since the exact reason why this happens is undetected.Now this FIX is only for this particular issue not for any other Android related issues. So don’t blame me or call me a cheater even if this didn’t work for you sometimes it may not because your phone’s internal architecture may be different and it is possible that the fix may be different for your phone.I am just sharing the fix that I used on my friend’s phone and his phone is working smoothly ever since.
