Android 12がリリースされたのは，去年の10月<\/a>だそうです．それから7か月を経て手持ちのスマホにもAndroid 12が降ってきました．<\/p>\n\n\n\n

iPhone\/iOSユーザーには何の話かさっぱり解らないと思いますが，Androidの世界はこんなもんです．Googleが正式リリースしてから，各メーカーが自分のスマホ用に整えて，順番に提供していきます．OSのupgradeを提供しないメーカーもあるそうなので，半年あまり経ってからでも降ってくるのは幸いです．<\/p>\n\n\n\n

もう一つ驚くのは，OSのupdate（パッチ当て）が何か月に1度なのです．これもたぶんメーカー次第なのでしょうけど，セキュリティー大丈夫なの，と感じてしまいます．<\/p>\n\n\n\n

で，めでたくAndroid 11から12になりましたが，ボタンの見た目が違うとか，GUIが遅くなったとかいう以外に特に大きく違うことはないです．<\/p>\n\n\n\n

しかし，重大な問題として気がついたのは，モバイルデータ通信の量が増えたことです．Android 11だったころの2〜3倍のペースで増えています．<\/p>\n\n\n\n

といっても，もともと1か月に400MBくらいだったので，このペースで行ってもせいぜい1GB前後の見込みです．<\/p>\n\n\n\n

今日気がついたのは，外出から帰宅した後，家のWifiにつながるまでにかなり時間がかかると言うことです．Android 11の頃は文字通りシームレスに切り替わっていました．この切り替わりの遅れ（あるいは，家にいてもWifiを使わずにモバイルデータ通信していると疑っています）で，通信量が増えているものと推測しています．<\/p>\n\n\n\n

しばらく様子を見ますが，たいしてめぼしいものがなく，こういう不具合だけ目だつというのでは，OSのupgrade提供もありがた迷惑です．<\/p>\n","protected":false},"excerpt":{"rendered":"
