What to Know About iOS 11.3 and 3D Touch Problems
Ah, iOS, our old nemesis. Every time Apple comes swooping in with bug fixes, it sprinkles in a few new ones. With the introduction of iOS 11.3, reports are flooding in that upgrading disables 3D Touch on iPhones. That goes for new and repaired phones.
Gadget Hacks reports this is a prominent bug on the iPhone 7 Plus, iPhone 8 Plus, and iPhone X, but that it may affect others, too. The silver lining is this bug doesn’t brick the phone. It temporarily disables 3D Touch shortly upon unlocking the screen with Touch ID or Face ID. It may also cause lock screen notifications to malfunction.
Some sources recommend running through a gauntlet of soft fixes like cleaning the home button, disabling 3D Touch, force restarting, and re-enabling 3D Touch, or re-adding fingerprints, but don’t count on any of those steps to fix the problem.
What’s the real solution?
If it’s not too late, don’t upgrade to iOS 11.3.
If it is too late, try downgrading to the previous version of iOS to ride out the bug fixes in safety.
If it’s too late, and the bug is more severe than expected, the issue may be hardware-related.
Expect questions from customers
This is a pressing concern because iOS 11.3 is a tempting upgrade. On top of performance and security enhancements, it promises a fix to Apple’s infamous battery throttling (in iPhones 6 through 7 Plus) by sharing battery performance stats and allowing users to turn off throttling.
For now, educate as many customers as possible on the risks of upgrading to iOS 11.3 until a bug fix comes along. It won’t be worth the enhancements if 3D Touch goes away.

How to check optimal WAN MTU settings.
The primary reason is that in most if not all cases if you send packets at 1500 they will need to be fragmented resulting in degradation of performance. I would not reccomend changing the MTU settings without first checking the optimal settings for your environment, do not just take the word of your ISP, they are making a generalized statement that covers the masses, it is not a total optomization.
Checking is easy to do. First make sure that your MTU setting is in fact 1500 or the test is compromised and will result in a number that is too low.
The command is to see the largest packet is “ping -f -l XXXX www.XXX.com” -f -l forces the ping packet size to be what you specify, any size to lage returns a reply that the packet needed to be fragmented.
-l is a lowwercase L
XXXX is mtu speeds start at 1500 and decrease in multiples of 10 (1500, 1490, 1480 etc…) until you get a ping result, then increase in multiples of 1 until you again get the reply that the packets needed to be fragmented. The highest numbet that did not have to be fragmented is your highest optimal number. I would actually suggest decreasing it by 2. So if 1464 is the highest you could send without fragmentation set the MTU to 1462.
and XXX is a website of your choosing.
When a print job is sent to the printer, the printer will display processing job on the control panel, and will continually ramp up and down attempting to print the job. After several minutes the printer will return to ready without posting any error messages. Occasionally, after several minutes the print job will print
This usually isn’t a roller problem as the printer WILL pick up the paper, it just takes a few minuets, but it never hurts to check. Next check the firmware. If it’s older than 04.060.7, then it is causing a fault in the fuser. This is a documented problem and the fuser needs to be replaced. In addition, the firmware needs to be upgraded to version 04.060.7 or higher to prevent this error from recurring. You can download an executable firmware upgrade utility from :
Don’t forget to update the firmware to the latest version, if you haven’t already done it, to prevent the new fuser failing with the same fault.
