15 days with iphone 15

I have used iphone 15 for couple of weeks now. I have taken a bunch of calls, gone on a trip with the iphone, shot about a thousand photos and about a hundred videos, ran out of battery while doing all this a few times, had the phone heat up well enough, but did not cause any issue, I have used it for few whatsapp calls of 1 hour plus time, connected few bluetooth devices and overall used the iphone quite well. And I have found so many annoying things. It feels like a bunch of features are crazy well thought out and slickly done. At the same time there are some things which are quite annoying. Some things failed unexpectedly, and getting data out of the iphone was a pain. So I'll touch upon the good and bad things below. Maybe in future I'll edit the lists and update this article. Bad things(because people love failures... no, they like pointing out failures): * ITunes would not work for me to transfer local music to the iphone. * I ended up getting some third party software th

WiFi interference with Bluetooth

I was facing this issue of sound clipping with the bluetooth adapter that I have connected to my Sony Speakers. Turns out it was due to interference from 2.4GHz WiFi connection. Thankfully my WiFi router has a 5GHz wifi SSID and I could connect the laptop to that and the bluetooth audio issue was resolved. Maybe it's time I moved on to 5GHz wifi. I'll have to check which devices don't support 5GHz WiFi and if there's nobody I can safely disable that SSID. Anyway less exposure is always better for security. Cheers!!

HP's crap software strikes again

So my laptop has been working fine with Windows 10 to 11 with regular updates etc and nothing went bad for a good while. Then this morning I'm greeted with an update error. The problem was shown as "Hewlett-Packard - USB - 40.11.1109.1746 install error code: 0x800f020b" I had this stupid HP MFD and this had some leftover bits on windows. First thing I did was checked installed software list to see if I missed anything when I removed all the software related to this printer couple of years ago. Could not find anything. So went into printer list and checked if anything is left there. Removed couple of unrelated printer things related to one-note etc. And then restarted the laptop - because it's windows. Still the same error. Then did a bit of googling and realized the drivers are still there. Tried to find the drivers but thanks to Windows 11's half-assed under-development control-panel+settings stillbirth, could not find them. Took another google search to find the

Saltwater demise of Redmi Note 7 Pro

The redmi note 7 pro that my wife has been using recently got splashed in some seawater. Of course it was the death knell for it. After bringing the dead phone home I dried it with a hair dryer. Then when it still wont take any charge, so I went on to open it. Of course without proper tools its frame got butchered. But I was able to open it and clean the corrosion and salt residue with help of an earbud. But the bottom board was quite corroded with the usb port too in bad shape. I did clean it to the best of my ability and decided to use it for as many days it would run. I packed the rear using some T7000 adhesive for 200 bucks. And it workwd fine for about a week. Then one day it died on me and battery would not charge. I realized that finally it has given up. So today I reopened it and checked if things are even worse. And there's some more corrosion. Anyway now its too bad that Im just going to pack up and sell this for parts. I have seen people collect bunch of things when they
