First off, I don't have computer atm. I have few question related to the title. 1. Can I root my phone through any app, if yes how much safe it is? I heard about brick so can it get bricked? then phone totally unusable? 2. After rooting can I play armv7 games? if yes is it practically playable or laggy, I will be needing to install custom rom for it? is it possible without computer? 3. phone gets heated a lot already so,after doing it and increasing clock speed it may cause serious damage?
