Hi,
I have updated the HTC One to Android 4.4.2. The resulting bugs should be well known, but I have not even found a hint at any solutions. Is this a troublesome topic?
----- Here is my list: -----
-- the dialer. It requires Wifi to be off to make a call. If Wi-fi is on, it stops when it would ask for SIP or no SIP. It used to be sufficient to remove all SIP accounts, but no longer. Maybe it works sometimes with Wifi running, but I suspect when it ever worked, Wifi was just broken.
Is the dialer part of Android or is it HTC One specific? Are the bugs HTC one specific?
Is there any solution, an alternative dialer that accesses the standard address book, can do SIP and works?
I'm a little confused: do you want to use SIP or not? You talk about removing all SIP accounts, which suggests not, but if you don't then there really should be no problem: set no SIP accounts and set "Use internet calling" to "Only for internet calls" rather than "ask for each call". Those are my settings, and I've never had any problem with WiFi on/off.
The dialer is HTC software.
-- Google Maps. It has been not very useful before, as it can not act in any way on any "favourites", "starred places", or addresses. Trying the "person" icon only starts a "wait forever" animation. There is now one more bug, where it just hangs after using it for 1-2 hours. Sometimes it complains it has no GPS signal when this looks bogus, sometimes the screen hangs but speech output continues, and the only fix is to kill and restart the app.
This is part of Android 4.4.2, as it is the exact same in a Samsung device.
Is there a way to install an old version of Google Maps? Is there any good alternative? Is there a way to retrieve old "starred places" including descriptions/titles and import into any other app? I'm not much of a Windows user, so I can make a script to convert text, csv, and similar files.
I'm not sure what interactions you are looking for. On my device it can go to my starred places, or to the addresses of people in my address book. I'm not sure which "person" icon you mean (I never used the old Latitude system though, so if it's related to that I'm not the person to ask).
I've not experienced the hang-ups you describe, but don't use it for navigation very often.
There are offline mapping apps, at different prices and with different capabilities. I keep a copy of Maps.ME on my phone (formerly Maps with Me), since Maps 7's offline map caching is even more limited than Maps 6's, and I travel internationally and find it useful to have stored maps. But that one doesn't do navigation.
-- the performance (latency). The whole system has frequent latency spikes of 1-2 seconds that convert any taps to the touchscreen into holds, that means essentially that the touchscreen works incorrectly. Playing games is hard, and if the home screen weren't locked it would be messed up.
I'm not sure if this is Android specific. I guess any solution requires root.
Never encountered this.
-- the performance (speed). I guess it is somewhat slow overall. I haven't seen any performance settings. Maybe there are hidden or locked performance options that have been set to "lowest possible performance"?
No, there are no such hidden settings. Again, I've not had a loss of performance.
However, I am rooted and so have more options, including the ability to wipe all caches. See the end of the post for the significance of that statement.
-- the Wifi sometimes loses all data (2x in a few months), as if it erases wpa_supplicant.conf. This demonstrates also that "Backup all passwords etc. to Google servers" does not work, at least for the restore part. There is not even a way to manually restore.
I'm not sure if htc one specific, but I haven't seen it on any other device.
Again, never experienced this.
I guess the trivial solution involves root and doing something with wpa_supplicant.conf, including moving it from another device. Is there a solutionthat does not require root, like a hidden Google Restore?
-- any other common problems due to the current software?
-------
I don't care much about cosmetic or luxury problems, like if colors and styles don't match or the screen is cluttered. I think like an old style Linux/Unix user, so crashes, broken essential apps, and repeatedly doing tedious unnecessary time wasting work (wifi) are considered major problems.
any hints?
thanks
If most of these problems started after an update, there's a reasonable chance that you can fix them by doing a factory reset (after backing up important data).
Over the air updates are patches designed to be applied without data loss, but you can sometimes get conflicts which can affect performance or stability after the update. Erasing all caches (the cache partition and the dalvik cache) should fix those, but without a custom recovery you can't do the latter without a factory reset. Many people recommend a factory reset after a system update, and while I don't myself go that far if you find you are having a lot of problems like this after an update I'd certainly give it a go.
Otherwise, what network are you on? Different carrier's handsets will receive different updates, so it's possible that your problems may be specific to one network, in which case if we know which one other users with the same software may be able to compare notes.
. First i thought it's a problem with my charger, but it's working when the phone is switched off. Cannot connect to my laptop too. Data cable also not working when the phone if switched on.
. But i have updated many OTA Updates over the past one year. This is the first time i have faced a issue.
