How do I know if someone has blocked me on their cell phone?
Usually the call/contact blocking softwares in phones reject your call automatically and filter your text messages so that they don't appear in the messaging app. So the best way to find if someone has blocked you or not is to call them, if you receive a busy tone/user busy all the time then there's a 90% possibility that you're blocked.EDIT:What I've written above is valid for some cellphones by Motorolla and Samsung and Nokia's s30/s60 smartphones (Yes, I've used this feature myself). On Android or iOS smartphones the call blocking apps just hide the incoming call interface so the user doesn't know if someone's calling. The bell rings from the caller side though.
I have accidentally disabled/deleted the default gallery app from my Moto G. It doesn't show in apps. How can I get it back?
It is difficult to delete system apps. One cannot delete system/default applications on and android phone without root permission. One of a couple things probably happened. the app became corrupt and is force closing when you try to access it. if this is the case, go to settings>apps>all, find the gallery app, and clear data and force stop it. this should fix the problem. The other thing that could have happened, is that you disabled the app. go to settings>apps> (depending on what version of android you are on, there are 2 spots for it. either go to all,and scroll all the way to the bottom, and you should see gallery there, click on it and hit enable, you also might have to scroll over to disabled and the app will show there, then do the same steps as above) now you should be all good. if you are still having problems, reboot the phone and see if that helps. if you are still having problems, a factory reset needs to be done. Don't worry, reboots do nothing to any of your data. pics and videos, and apps and such will still all be there. factory resets are different for every phone unfortunately. Delete everything on the phone. So keep back up your data. Downloading of your apps is going to be necessary (although it should start automatically once you sign into your google account)
How can I fix the "an error has occurred. Please try again later" message I receive when I try to connect to YouTube (process com.google.android.youtube)?
Here are some I came across little Googling,1. Try to get rid of cookies Here's how to do it, from Google Groups a. Go to "YOU TUBE" site, b. Click "TOOLS", c. Click "DEVELOPER TOOLS", d. Click "CACHE", e. Click "CLEAR COOKIES FOR DOMAIN" f. Click "YES", g. Close BOTH windows. 2. Give a try with another profile3. Verify if it's an issue with rooted device4. You might need to use good process and cache cleaner software which will remove all junk files in the memory (I use Clean Master on Google play store )Most people on above mentioned forum seem to have solved this issue just by clearing out cookies.Hope this helps!
How do I find my husband’s hidden apps?
First and foremost, DOES your husband have hidden apps?Why do you think it is necessary for you to look for “them”? Is it insecurity on your part? Has he done something objectively to make you suspicious?You are bargaining yourself into dangerous territory. Snooping, or rather invading someone’s privacy is getting into an environment in your relationship that is hard to get out of. Since trust is really a very fragile thing.Now, having said that, and assuming you are honest, mature and actually have decided to do that. I will give you some pointers.I cannot give you the exact way to find your husbands hidden apps because I have no idea what apps he may have installed in order to hide apps. As apps that can do that are a dime a dozen.However, most end users tend to hide their pass through their launcher. So that would be your first option. Most 3rd party launchers have an option to hide (not very well) apps from prying eyes. You usually can get around that by going to settings and looking up the “hidden apps” section or something that reads “show hidden apps,” or something to that effect through the launcher app itself. However your mileage may very as stated, depending on the launcher and its settings. Also in some cases, they may be protected by a password, or at least the better apps do.Personally, I would not even bother with that and simply use a file manager app and go into Root/system/app, that folder usually has a listing of EVERY SINGLE APP he may have installed on his phone as a user app. It does not cover every app, but 98% of users out there don’t know any better so they are bound to just have installed it there because that is what phones do as standard. Likely, unless your husband is either in IT but lazy or a regular end user, then the app(s) you are looking for are going to be in a folder there.Now, I assume you are not very technical at all since you literally forgot to mention WHAT KIND OF PHONE AND OPERATING SYSTEM your husband is on. The instructions I have given here are from Android phones although I cannot imagine it would too different on iPhones.Again, I would highly suggest you thread carefully. Perhaps use a more direct approach and ask him directly. At least this way you keep your decency, since if you find out that you went through this stuff, well, you know.Good luck.
