Here's some background information to get things started: - my cell provider is Alltel - I have an HTC Hero; I'm using Android 2.1 OK, I have a really, really strange and frustrating problem. Somehow, someway, my phone will stop receiving text messages. It seems strongly, strongly correlated to downloading new apps via the Market. When I first got my phone last June, I downloaded some of those Task Manager apps. Around this time, I found that I stopped receiving text messages. I once with like four days without receiving a text, which is odd, because I text fairly regularly. It finally dawned on me that my phone wasn't retrieving messages properly. I restarted my phone, sent a message to my bank to get my balance, and instantly received a text from them. I DID NOT, however, ever receive the messages I had missed over the previous four days (and I'm positive people had sent me some, because they mentioned it in person). I concluded that the Task Manager had probably killed one of the processes that fetches text messages, so I decided to just factory reset my phone on the safe side. I've went MONTHS without having any problems, and I've been very, very conservative about installing apps on my phone. I use only a select few at this point. I have not had any problems whatsoever. A few days ago at work, a couple of coworkers of mine told me to check out some games -- I think it was like "Mighty Miners" and then some construction, bridge-building game "X-Construct." Within hours of installing these games, the same old problem reared it's ugly head -- I stopped receiving texts. I'd restart, I'd get texts again, but they would eventually stopped being retrieved again. (Again, I always test this by sending a message to my bank, which will give me an instant reply) I factory reset my phone, and have not had any problems again. I'm getting really frustrated, because it seems like downloading apps off of the marketplace is a complete crap shoot for me. I sincerely doubt that some of these apps -- ESPECIALLY games -- would have any affect on something like that. Something like a task manager? Sure, I can see that. But this problem has happened probably 6-7 times. I have literally factory reset my phone that many times because I just outright lose the ability to receive texts with any reliability. I don't think this is a problem with my provider, because it seems strongly correlated to installing new apps. I also fail to see how this could be an issue with my phone, as opposed to just a generic Android issue... Has anyone heard of something like this? Any clue what could cause this? I'm basically at a loss, and feel like I almost have to give up my ability to download apps of the marketplace because of how much of a crap shoot this has turned out to be. It's like playing Russian Roulette, with a really good chance of my phone being rendered useless until I factory reset again. Also, there are a few select apps I download every time I get my phone; I will sometimes have these installed for months without any problems at all. I've problem had the "no text" problem instigated by at LEAST 5-6 different apps.
