Autocorrect in different language

Had the exact same issue!

Went into my settings and searched for “spell check” and then got a various few menu options - if you go into your keyboard options, you see your different languages. It seemed like some of mine (Latvian amongst them) somehow had gone to sleep in the cloud, and I needed to press the cloud to redownload. Afterwords worked all fine!

Yesterday my iPhone automatically updated to ISO 17.4.1

You may have Turned on automatic updates

• Go to Settings > General > Software Update.
• Tap Automatic Updates, then turn on Download iOS Updates.
• Turn on Install iOS Updates. Your device will be updated automatically to the latest version of iOS or iPadOS. Some updates may need to be installed manually.

Update your iPhone or iPad - Apple Support (IN)

That also resolved it for me! Under Settings > General > Keyboard > Keyboards my various language keyboards had little cloud download icons. After re-downloading all keyboards they again work fine.

While smartphones themselves can't harbor malicious intent, we must actively fortify their defenses. Tighten your device settings, be mindful of how you sync, and protect your digital treasure trove by safeguarding sensitive information with your loved ones. Don't underestimate the power of simple security measures. Employ strong passwords, enable two-factor authentication, and regularly update software.

 However, the vulnerabilities lie in our usage and connectivity. Unsecured settings, careless syncing, and oversharing sensitive information can transform this innocuous device into a Trojan horse for attackers. Vigilance is key.

If you feel an unauthorized person/app is remotely using, controlling or monitoring your device, then that is possible only if you have done one or more of the following Don'ts...

1. Don't hand over an iPhone to kids or to a stranger without Enabling Guided Access
2. Don't share Apple IDs
3. Don't Jailbreak
4. Don't share sensitive information pertaining to your device
5. Don't give in to Phishing
6. Don't plug in your device in Airports and Public places through third-party cables and trust the device. Beware of Juice Jacking. (Especially in India)
7. Don't leave your iPhone unlocked and unattended in public places like offices, schools, malls, etc.

If one of the above is true then quickly change the Apple ID Password and Return iPhone settings to their defaults.

A million thanks and PALDIES @ARoso, very useful tip how to solve my Latvian typing misery! Like others, I was happy with my rich Latvian dictionary database and suddenly in one day it’s all gone! Cloud/sleep mode sorted now!
