How to get text messages on lock screen?

I already get text messages and imessages showing up on lock screen. My problem is i want it to show up like "Text Message" and the persons name, or "iMessage" and the persons name, I don't want what the person wrote to show him, instead i want it to be written only "Text Message" and "iMessage". I have iphone 4s and ioss7… I used to do this on my old iphone 4 ios6, and was perfectly fine. Anyone know

  • Why is my iPhone5 sending some messages as iMessage and others as Text Messages? I understand that messages are sent as Text Messages when there's no signal or poor Wi-Fi connection. However, I'm successfully texting some people using iMessage but others (still iPhone users) as Text messages. The other person will send iMessages and then my responses will be sent as green Text Messages.
  • When I receive text messages with emojis from an iPhone, why do the messages only appear partially? My phone is a "Verizon Samsung Intensity II" slide phone. (Also it's blue but that doesn't matter.) Also, if I'm included in an iPhone group chat (spoiled rich friends, but not snobby…), I get each posted message as a separate message, so I'll end up randomly with 67 unread messages clogging up my inbox.
  • Is there anyway I can get my text messages to show on my lg g2 screen? I just bought the new lg g2 smartphone and whenever I get a text message I have to unsleep the phone just to see who the message is from. Is there anyway I can have the message show up on the screen if the phone is on sleep similar to what the iPhone does? Or at least show who the message is from. I hate having to unsleep the phone and enter my password every time
  • How to lock my text messages? I know I can lock my phone, but my text messages. I have an Iphone 3G. I let my parents and friends use my iphone, but when they do I don't like them going through my text messages. So can I Specifically lock just my texts?
