I have thousands of gmail, my LG L70 has been running slow. Do gmails take up memorie or space. I have no external sd card. I think i have a built in app for changing or moving files. Whatever you guys were talking about where people were asking questions about space and apps and foles. I have never had a phone with so little space
How much space email takes up varies. Gmail is IMAP email service, so email is kept on the server. However, some is saved on the phone for easy, quick offline access. Email apps have a setting for how much email to keep on the phone. Depending on the app, it may be stated in days of email or the number of emails.
Whether you save a little or a lot of email on the phone makes no difference in the phone's speed. How many emails are in Gmail doesn't affect speed either.
Email saved to the phone does not go on the removable SD card even if you had one. It goes to internal memory. So to maximize space set the phone to save a minimal amount of email to the phone, maybe 25-50.
