Simple question. I work in a basement office and my network signal is very patchy at best. Is there a way to get a notification (buzz preferably) when it finds a signal? I have an HTC One running Kit-Kat (4.4.3). My favourite search engine hasn't given me any joy.

AFAIK there's nothing built-in to be used. And for apps, I only know the opposite: buzzing you when the alert is lost (see: Bad Signal Alert).

However, you could use to create your own customized solution. Tasker can monitor signal strength, and you can setup a profile to utilize that. I cannot give you the matching profile currently, but you might wish to take a look at What is Cell standby and how can I keep it from eating my battery? In my answer there I've introduced a longer configuration involving the necessary tasks, so you might be able to adapt them to your needs. In fact, the SigReturn task already does what you asked for: Whenever the signal is restored, it issues a vibrating notification.

Being older than 2 years already, it might need some polish, though :)

  • Keep in mind, signal strength is not always 100% accurate. What shows, or is reported, may not be the current signal strength. It's the strength that it had the last time it checked the signal strength. – Ryan Conrad Dec 31 '14 at 00:48

    @RyanConrad sure. That's why one always should have a "delay" in. If I remember correctly, I used something like "if signal strength falls below X, wait y seconds and check again. If it's still below X, act." Still not "really safe", but at least "safer" than acting immediately on a "fluke" ;) – Izzy Dec 31 '14 at 00:56
  • Yeah, I wasn't calling your answer incorrect in any way, it is actually a really good idea and could be reliable enough. – Ryan Conrad Dec 31 '14 at 00:58
  • @RyanConrad I didn't take it that way, no worries. I rather considered it a good and justified hint – and thanks for that! It's quite a while ago I last experimented with that profile (conditions improved, better signal now, so no need anymore) – so I really wasn't sure whether that was covered appropriately ;) – Izzy Dec 31 '14 at 11:32
