Method #3: Update or delete apps

The firmware on your iPhone XS Max can handle a lot more. Apps enable users to do much more and since they are usually updated almost once a month or more, these apps ensure that you get the latest features while an app update ensures fixing, resolving, or curbing any potential symptoms or even bugs that can cause the particular function or the app as a whole to crash at times. Thus, it is crucial to carry the same function.
Updating an app is a piece of cake. A step-by-step procedure will help you into it.

  • First, launch the App Store.
  • Go to the Updates section.
  • Check which apps have received app updates which are signified with an ‘Update‘ button that pops up against each individual app.
  • Click on the ‘Update‘ button and its done.
  • You can click on ‘Update All’ to do the same for all the apps with an update awaiting.

This will primarily fix issues caused due to an outdated app. But there’s a different section lurking at the corner and that’s bad apps or updates.

  • You can go to Home Screen and tap on any app that you don’t want and hold it.
  • The apps will jiggle on the screen along with an ‘X’ pops on the top-right of the icon.
  • Click on ‘X’ to uninstall the app and assert if there’s any confirmation to go through.

Method #4: Upgrade to the latest iOS firmware

As you already went through why updating apps is imperative, the same applies for iOS firmware update as it is a piece of software that acts as an interacting medium for apps (software) and hardware components to interact and make things happen on a smartphone like iPhone XS Max. Also, iOS update can resolve any system error or even the complex and fatal errors as you will be reducing the phone to be using nothing and then apply a new update but there are various other reasons that deem it effective as well. Anywho, you can use the procedure describe below to do it.

  • The foremost step is launch Settings app on your device.
  • Next is to proceed to the General >> Software Update where if there’s any update available, you can check it out, download it and install. Once you have installed, just reboot the phone and bingo.

If you are attentive towards the notifications that you receive, you might have seen an iOS update notification pushed through OTA as it is a usual practice. Simply update the firmware whenever you get the said updates and hopefully, it will shield you against a few bugs if not all.

Method #: The More Permanent Resolution

Irrespective of what issues you have with your iPhone XS Max such as the one “keeps rebooting by itself” or “random restart problem” you can walk through the above-mentioned methods trying to figure out a way to fix it. However, unless there’s a resilient software issue or a hardware issue, you can do it on your own or visit an authorized or third-party service center. The thing is, the former is expensive while the latter is inexpensive and effective but will leave you out of the warranty on the device so good luck with that too.
