Is there a limit within Android, or possibly set by OEMs (heard this from a friend who is a technician), of the total amount of SMS messages you can have? As in, messages within a thread and/or all threads combined? Not just the limit within conversations which you can manually set. I mean a limit android has coded into it, or one that OEMs set, that actually would "limit" (whether by slowing down or stopping) the number of SMS you can have?
And I'm not talking about a couple thousand, but even in the hundreds of thousands in a thread?
