Has anyone had any problems upgrading iPhone 4S to IOS 9.3.6 ? My 4S is currently 9.3.5 and working OK.

1. Download first then upgrade ?

2. Download with WiFi only then upgrade ?

Any advice on upgrading gratefully welcomed

I've got a 4S on 9.3.5 (not 9.3.6) that works fine (though slow) and there's nooooo way I'm going to install 9.3.6 on it because there's no way to go back to 9.3.5 if it gets wonky. Apple has a long history of introducing new bugs with updates and I don't trust them anymore for a non essential upgrade that might make things worse.

But perhaps I'm the exception. I've become extremely gun shy of iOS updates after having been burned too many times.

The only thing this update does is fix a GPS time glitch, it's basically the same version. I tried to install it from the Settings app on 9.3.5 but it never updated so I had to use iTunes.

This page explains the update: https://support.apple.com/en-us/HT210239 so it appears 9.3.5 will become "wonky" as of November 3rd.

Installed IOS 9.3.6 on my iPhone 4S last night through iTunes 12.9.5.5 on my Mac Pro last night.

Initially I couldn't connect to WiFi ( last night ) but today I find that the 4S is connecting to WiFi .. maybe it needed time to realise that it is now IOS 9.3.6. Caching ? No idea.

Everything seems to be working .

What really surprised is that this 4S actually seems to be faster in all operations !

I rarely need nor want to use my 4S for anything besides as a phone + LINE ( social media app popular here in Japan ) , music, photos.

The SIM is from a hobby knife hacked 3GS.

Think of the $$$$ I've saved not upgrading to iPhone 5, 6, 7 .

This 4s does everything I need to do but now a little faster ! ! ! 🤣

PS : The ONLY thing I've had to do since buying it for ¥5,800 = US$54.49 + 8% sales tax here in Japan in 2015 has been to replace the battery which took about 30 miutes.

Very happy with IOS 9.3.6.

IMPORTANT NOTE : Before starting the IOS 9.3.6 upgrade I set the 'Auto OFF' to Never.

While the update is just a bugfix, i heard it can cause some problems on those extremely old phones like the 4s. I guess it's because those phones have not seen an update in a long time (9.3.5 was released in August 2016). Especially when you update over-the-air, it can take forever. I hope you do not experience any issues now with the phone later on.
