The stock messaging app automatically converts SMS to MMS after size of 5 SMS. Any way to turn that off without installing some other messaging app? I know it's not problem with carrier, because on my last phone I used to send 20 SMS size
No, not yet. I root and s-off every device, but after few months of using them when I got bored with stock. I have this phone for 2 days so I won't root it yet.
