HTC EVO 4G suddenly turning 4G/WiFi on by itself

Hello,

I am not sure if this has to do with some updates my phone recently underwent, but it seems like I suddenly have 4G coverage in my area now (hooray!), and since then--within the past week--I've noticed that my phone insists on having either WiFi or 4G on at all times. I shut them both off at work to save battery, and inevitably I will check my messages later and find that whichever thing I shut off last--usually WiFi--has triggered the other one to turn on. This is annoying and should be up to me, not my phone. Unless 3G doesn't work at all, I can't understand the point of this. Is anyone else experiencing the same thing?

Thanks.

Check to see if the Sprint Connections Optimizer is turned on in your settings. It prioritizes 4G/WiFi connections over 3G since they are faster connections.

having your wif on usually will save more on your battery than 3G.. you should be able to go into your settings and turn of the connections optimizer (automatic connections on the OEVO..not sure if its called the same thing on the LTEVO) if you REALLY dont want the phone to have control..personally i would keep it running like this for a while and check it out..its going to automatically pull up whichever connection is the best...which usually means better battery life.

this comes in REALLY handy for those that always forget to turn off their wifi connections when they leave that wifi area..instead of it constantly searching for a connection it will only do it so often..

side note though. manually turning on/off either the wifi or 4G connection will reset the optimizer..it WILL however eventually turn itself back on.

additional side note..the connections optimizer will usually only search out connections you have saved to the phone already...unless you have the notifications deal checked...personally i unchecked it so its not constantly trying to link up and notify me of a new available connection

AHA! Thank you! Was that part of a recent update? I have never seen it before or noticed it taking over my phone, but I found it and shut it off. Thank you so much!

Re: HTC EVO 4G suddenly turning 4G/WiFi on by itself

Thank you! I REALLY do not want my phone controlling itself. My WiFi at work is not open. I have to apply for a password that I'm not allowed to change to something easy, and I have to retype that password every time I try to use the internet or check my email or anything at all, AND, I have to reapply for a password every 30 days. It could not be more annoying. There is a hidden WiFi that doesn't require all that bull, but it's only for company-supplied cell phones, which mine is not.

So I can shut off the optimizer, but I'm going to have to keep shutting it off every day? Did I understand that right? WHYYYYYYYYYYY? I think that's actually just as annoying as my previous problem, but at least I know what to do now. I'm sure many people have trouble understanding their cell phones (my boss, for example) and are perfectly happy to have their phones control themselves. But I much prefer to be the one in control. Ugh. Anyway, thank you very much for your help.

p.s. Forgot to say, the 4G signal strength inside my office building is poor, so leaving it on does not improve anything. Otherwise I would be happy to just leave it on instead of WiFi.

1-go into your wifi settings and uncheck wifi notifications. then go into your wifi connections and if you see either of those locations in there select it and then hit forget. that should eliminate it ever trying to pull those back up.

2-you should be able to go into settings-wireless and networks-mobile networks- and it should be under automatic connections. if you see it there then go in and uncheck it.

Re: HTC EVO 4G suddenly turning 4G/WiFi on by itself

true...but that 4G connection might be better than the 3G connection youre currently getting lol...worse case scenario (if youre only getting 4G at a few places and dont really use it as of yet) go into your settings and change it from LTE/CDMA to CDMA only...it will then not search for the 4G signal..even with the optimizer turned off it will still keep pulling up that 4G signal because its still looking for the LTE/CDMA.

No, if you turn off the Optimizer it will stay off. If you leave it on and manually trigger WiFi/4G on/off then it resets the Optimizer for a period of time before it adjusts the settings automatically again.

Re: HTC EVO 4G suddenly turning 4G/WiFi on by itself

Awesome, will do, thank you again. Also quick follow-up (after I threw myself under the bus saying that other people don't understand their phones, that was dumb!):  I did know that WiFi, when I can use it, does use less battery than 3G, but I just want to make sure: 4G still uses more than 3G, right? Battery-wise, it would not be better for me to stay connected to 4G even with poor signal strength than to revert to 3G?
