There may be several reasons due to which an iPhone may behave as described by you. Some of them could be...

Let's delve a bit deeper into some of them:

1. Storage: A full iPhone can definitely slow things down. Phones can experience performance issues when the storage is nearly full. Users can check their storage status by going to Settings > General > [Device] Storage. Deleting unnecessary apps, photos, or videos can free up space and improve performance. How to check the storage on your iPhone and iPad - Apple Support.
2. Battery Health: A degraded battery can impact performance. A deteriorating battery can impact the overall performance of an iPhone. Checking the battery health can be done by going to Settings > Battery > Battery Health. If the maximum capacity is significantly reduced, it might be time to replace the battery. Prolong and Maximise Battery Performance … - Apple Community
3. Incorrect Handling: Accidental drops or bumps can cause internal damage. looking at the Apple's guide on proper handling is a good step. Important handling information for iPhone - Apple Support (IN)
4. Environmental Issues: Extreme temperatures, dust, and water exposure can all be detrimental.
   1. Keeping iPhone clean is an important step. Dust accumulation in the iPhone's ports and openings can affect functionality. Apple provides guidelines on how to clean iPhones safely, which usually involves using a soft, lint-free cloth to remove dust without causing damage. Cleaning your iPhone - Apple Support
   2. Keep the iPhone within temperature limits. Phones are designed to operate within a specific temperature range. Exposure to extreme temperatures, especially in parked cars, can lead to overheating or other performance issues. If your iPhone or iPad gets too hot or too cold - Apple Support.
   3. Addressing safety issues is also important: Important safety information for iPhone - Apple Support (IN)
5. Unauthorized Service: Servicing an iPhone through unauthorized channels can result in substandard repairs and void warranties. Users should always seek authorized Apple service centers for repairs and maintenance.
   1. Repairs by unqualified technicians can introduce new problems. Find information about your warranty or AppleCare plan - Apple Support is helpful.
   2. Modification / Alteration of an iPhone by a third-party vendor may cause issues beyond repair. --> Unauthorized modification of iOS - Apple Support (IN)
6. Jailbreak: Now, let's talk about jailbreaking. Jailbreaking removes Apple's restrictions, allowing for more customization and app installation outside the App Store. However, it can also lead to instability, security vulnerabilities, and issues receiving future iOS updates.

By considering all these possibilities, you've provided a comprehensive approach to troubleshooting the iPhone's behavior.

Understanding and addressing these factors can help you maintain the optimal performance and longevity of their iPhones. Following Apple's guidelines and seeking authorized support when needed are crucial for a positive user experience.

If you are sure it is the fault of the equipment.

If you have either dropped the device accidentally or exposed it to liquid or used it beyond acceptable temperature limits then…

It's not always the iOS update's fault!  Many things can cause phone problems.  If you tell people you think it's an iOS update, it might make it harder to fix or find a solution for the real issue.

Remember, the right question often leads to the solution!

Was/Is your device Jailbroken? If that's the situation, please be informed that attributing the issues to iOS updates may not be accurate.

iOS updates aim to enhance user experience, boost security, and fix bugs rather than disrupt core features. The majority of the issues after updates might stem from underlying, unmentioned factors. Updates won't typically alter personal data but may refine settings or features. Backup before major updates for safety. Review Apple's update details and backup advice for a smooth process.

Kindly consider checking your settings and addressing any device issues before attributing the issue to external factors. This could be a pure coincidence that the iOS update affected the iPhone functions.

Before initiating a standard iOS update, it's advisable to create a backup. Have you completed this step? If yes, proceed with the restoration from the backup.

See what each update does: OS — iOS 26, About iOS 18 Updates, About iOS 17 Updates, About iOS 16 Updates, About iOS 15 Updates, About iOS 14 Updates, About iOS 13 Updates, About iOS 12 Updates, and so on...

This is the summary of what you are trying to say.

• iOS 26.2 (and all of 26) feels overloaded with bugs, lag, and missing functionality.
• Apple doesn’t seem to be listening, even after multiple feedback submissions.
• Feedback forms have character limits, making it impossible to describe all the issues — ironic, given how many there are.
• The keyboard is slow, laggy, and struggles to display typed text properly.
• Screen responsiveness is delayed; swiping feels inconsistent.
• A strange “click bubble” lingers after tapping items.
• Safari is noticeably sluggish.
• Settings keep changing in ways no one asked for.
• Apple pushes constant “suggestions” (mail unsubscribe prompts, car suggestions), even when they’re turned off.
• Turning these suggestions off wasn’t intuitive or user-friendly.
• App switching is clunky, slow, and sometimes unresponsive.
• Screens freeze or hang before finally responding.
• Lock-screen customization is limited — can’t even change the date format the way you want.
• Overall, this isn’t a handful of glitches but a long list of frustrations unlike any past iOS version.
• Official feedback has already been submitted — this is simply sharing frustrations with the community.

That's correct. Each feedback you submit should be about one issue. Different issues will get routed to different teams.

Siri Learns

Siri Suggestions is a feature that helps enhance your experience by providing intelligent recommendations and shortcuts. It learns from your actions and app usage, gradually understanding your preferences and routines. The list of suggestions will automatically populate based on the apps you use, the times you typically use them, and your interactions with your device.

For example, if you often message a particular contact in the morning, Siri might suggest sending a message to them around that time. If you frequently listen to a specific playlist or podcast on your commute, Siri will offer that suggestion when you're typically heading out. Similarly, Siri can offer suggestions for actions like opening apps, setting reminders, or using shortcuts based on your behavior over time.

These suggestions are personalized, meaning they adapt to your habits and can change based on the context of your day, helping you save time and stay organized without having to manually search for apps or tasks. You can access Siri Suggestions from the lock screen, the search bar, and even in the "Siri & Search" settings, where you can customize how and when they appear.

Make Siri Forget.

To unlearn or reset Siri Suggestions, the only way to completely clear Siri's memory of your past actions is to restore your device from an old backup. This process essentially reverts your device to a previous state, including your app usage, preferences, and habits that Siri has learned.

When Siri Suggestions learn from your behavior, they collect data about the apps you use, the contacts you interact with, and the routines you follow. While you can disable or limit Siri Suggestions in the settings, they will not be fully reset unless you restore the device. This means the suggestions will still be based on your current usage, even if you turn them off.

If you wish to clear this learning history, restoring from an old backup—preferably one before Siri started learning or making suggestions—will remove all the stored data. However, be aware that restoring a backup will also revert your device’s settings, apps, and data to that previous state, which could result in the loss of more recent data.

Disable if you do not want the suggestions.

And feedback works both ways. I sent feedback thanking Apple for iOS 26 as I think it's a GIANT leap forward.

To improve my understanding of the phenomenon, it would be highly beneficial if you could share a full screenshot (Do not crop it). Visual representations carry a greater impact than written descriptions.

Please remember that this is a public forum, so when attaching a screenshot, please avoid including any personal credentials such as IP addresses, card details, email IDs, Apple IDs, IMEI numbers, serial numbers, phone numbers, order IDs, or any identifiable location information if you are sharing a map.

With the limited information that you have provided, It is hard to even guess the problems faced by you.

Please re-post with detail so that someone else can help.

sorry to read about your experience and the impact it causes, Fortunately I don’t encounter any of these, I truly enjoy OS26 especially liquid glass, I wish you to fond a resolution to your problems and as suggested in this forum, contacting Apple Support might be a good starting point I wish you to resolve your points and enjoy this beautiful device at its full

Feedback is your best option as you have said you submitted. I don't experience the screen delays when typing as you have described with iOS 26 and personally I appreciate the Unsubscribe option that is visible on an email that was generated from a mailing list. It is not like it is intrusive or prevents me from interacting with the email and reminds me that I had subscribed to a mailing list where I can also remove myself.

Opinion based posts are best addressed through the feedback, since this is a Support Site where neither of our opinions matter when it comes to providing a Support solution. That would be something that is seen on a Social Media site, which this is not. I do believe SravanKrA has posted detailed steps for the issues that can be addressed by you that is not simply based on an opinion or rant.
