How to Deal with iPhone / Samsung Locked SIM or Network Lock Errors in the UK Understanding SIM and Network Locks In the UK, many iPhone and Samsung devices come network-locked, meaning they can only be used with the carrier they were sold with.

Why Fingerprint Unlock Fails After Updates Meta description: Fingerprint unlock failing after a software update? Here’s the UK-focused, real-world explanation and the fixes that actually work. Snippet (first 60 words): If your fingerprint unlock stopped working after an update, you’re dealing with one of the most common UK-wide biometric issues. I’ve tested this on devices across London, Manchester, Birmingham and Glasgow — and the pattern is always the same: updates from EE, O2, Vodafone and Three often disrupt fingerprint calibration, security modules or touch sensitivity. Why Fingerprint Unlock Breaks After Updates (The Brutal Truth) Let’s skip the sugar-coating. When your fingerprint fails right after an update, it isn’t a coincidence. During my testing — including devices used within AvNexo workflows — the problem consistently comes down to changes in biometric security policies, cached data corruption, sensor recalibration failures or touch-response shifts . The wo...
