Disgruntled Apple customers are flocking to Twitter to report glitches with the iOS 9 update, which they say has crashed their devices and rendered them inoperable.
Some users trying to upgrade their devices received error messages during the process, while those with older devices reported having their devices lock up when they were trying to upgrade, according to CNBC.
Those who take their crippled devices to the Apple Store have been told that they can either return their phones to factory settings, and potentially lose any data that has not been backed up, or wait for a fix.
While many tech experts encourage users to wait a few days, or even longer, before installing a software update, so that the bugs can be found and fixed, some people are determined to be early adopters.
While Apple’s cohesive and uniform operating system is lauded as one of its biggest assets, there is a downside to Apple releasing an update to the masses all at once. Tech analysts believe that many of the current update issues that users are experiencing are due to overloaded servers.
Apple store employees told disappointed customers that engineers were working 24/7 to fix the issues.
This is not the first time that Apple has run into problems with a software update, as iOS 8 faced similar issues and significant bugs.
